Materials, safety, life science–Resources in “Science and Children”

Children painting on various materials using a thin and a thick consistency paint. Children I work with on a weekly basis have been exploring different types of materials as they work with them. Painting with thick or thin consistency paint (see the March 2015 Early Years column), running their hands through a pile of small stones before sending them through a tube, working with ceramic clay formulated for children’s use, and trying new kinds of play dough have provided them with experiences that involve testing the properties of materials. The children have also been making choices about which tool to use to achieve their purpose, measuring using informal units and making models to represent objects.

IMG_5261aChildren putting small stones through tubes.Children use craft sticks to incise ceramic clay.

I used the “Safety First: Safer Science Explorations for Young Children” by Ken Roy in the March 2015 issue of Science and Children to check my materials for safe use by children ages 2-5 years. Of course, the small stones were put away when the children who still “mouth” objects were in the room. Following the column advice, I kept damp paper towels in the area where clay was used to wipe up clay dust before it went airborne.  

A squash seed has sprouted.Alongside this exploration of physical properties and possibilities, we have been growing some squash plants from seeds the children excavated from inside the butternut, kabucha and pumpkin squash fruits. It’s a little early for our location to sprout seeds to put in the garden later unless you have an ultraviolet light to supplement the sunshine on the windowsill. We don’t and we may not have a garden space this year. But we can still explore life science concepts. The Early Childhood Resources Review in the print and digital February 2015 issue of Science and Children describes “Tools of Science Inquiry That Support Life Science Investigations.” 

I think I’ll make a basket of these items to have at hand for our nature walks and playground time.

Logo of NSTA Learning CenterThe NSTA Learning Center Early Childhood Forum is a great place to post a question asking other educators about a standard, lesson plan or concept. Create an account, and join in the conversations. As I tell the children, “Scientists don’t always agree, and that’s okay. We keep trying to learn, together.”

Climate Change and the Anthropocene

graphic saying Science and the STEM Classroom looks at climate change and the anthropocene

This past winter was extraordinary for many parts of the United States. New England saw unprecedented amounts of snow, while the Sierra Nevada mountains in California, famed for skiing, saw barely any. Lower-than-average snowfalls in the Sierra Nevada over the past several years have created California’s serious drought situation. In Delaware, where I live, we mostly escaped large snow events but temperatures have been below normal and there have been snow flurries in much of the state at the end of March, which are both unwelcome and unusual.

Paleoclimatology Data

Severe droughts, floods, frequent tornadoes, polar vortices, strong monsoons, and record snowfalls are all hallmarks of extreme weather. Scientists think that extreme weather is linked to climate change. There’s also strong evidence that human activities are contributing to extreme weather and probably to climate change. It is true that extreme weather events have been a fact of life on Earth for millions of years. But it is also true that extreme weather events appear to be increasing in both severity and frequency. We know this because of the range of paleoclimatology data available to us.

Paleoclimatology is a field that has ancient roots, beginning with Egyptian recorded observations of drought and flood cycles along the Nile River. The Egyptians marked these events because the Nile floods deposited fertile soil on the fields along the river where much of their food was grown. Evidence is now mounting that a severe drought may have been responsible for the collapse of the Old Kingdom, 4000 years ago. Evidence of similar conditions has been found for Mesopotamia, another ancient civilization, where cities were abandoned at approximately the same time and soil deposits indicate a drought that may have lasted 300 years. A thoughtful review of several recent books by historians on climate change, economics, politics, and human geography can be found here. The books describe the rise and fall of numerous civilizations as a result of changing climate.

How does paleoclimatology inform our current understandings of climate events? Current computer models that are used to predict weather and longer-term climate are populated with the results of paleoclimatological studies. Much of the data gathered in such studies comes from the use of climate proxies to infer what conditions were like thousands or even millions of years ago. Some of these proxies include calcareous organisms such as diatoms, foraminifera, and coral; ice cores, tree rings, and sediment cores.

Sediment cores contain pollen and other evidence of climate and weather events over time. Palynology is the study of pollen in the fossil record. Pollen can tell us what kinds of plants lived in the study area at a particular time. Because certain kinds of plants are adapted for certain kinds of climate, scientists can track climate change over long periods of time by inference using plant pollen.

Another important source of paleoclimatology data comes from polar ice cores that preserve atmospheric oxygen isotope ratios. When sea water evaporates as a result of rising air temperatures, it tends to leave a higher percentage of heavier oxygen isotopes in the ocean. When this water freezers, a record of the higher temperatures is left behind in the ice. Ice cores preserve a wealth of other information such as atmospheric dust, pollen, volcanic ash, and pollution. The current ice core record dates back 800,000 years in Antarctica. But scientists think that there might be ice as much as 1.5 million years old on that continent. Some evidence from ice cores is pointing to a global cooling trend that occurred in the late Holocene (up to about 1800 years ago), ending with the Little Ice Age. Temperatures today are still in fact below long-term global averages.

Some scientists are advocating for the designation of a new geologic era, the Anthropocene, to indicate the effect that human activities have had on Earth’s environment. A working group of stratigraphers is currently developing a scientific basis for this new geologic era. There is active debate about the necessity of a new geologic era as well as what event should be chosen as the start of the Anthropocene. Some scientists feel that the first atomic blast is an appropriate starting point, while others suggest the beginning of agriculture or the start of the Industrial Revolution.

Developing a STEM Unit

To develop a STEM unit around paleoclimatology and its possible relation to current extreme weather events, you might like to include a number of elements. Biology teachers or a local botanical garden can help you determine which terrestrial biome applies to your area and help identify which kinds of pollen might show up in the fossil record for your area. You might be able to compare your local pollen with pollen assemblages from other climate zones. Work with a geography teacher to understand what effect historical weather events such as droughts and floods have had in your area.

A physics teacher could help you understand heat transfer and its effect on ocean circulation. Ocean circulation is the engine of climate, so this concept is at the heart of our current understandings. This is part of the reason why changes in polar ice cover are so concerning for many scientists. The uncertainties around the possible outcomes of melting polar ice highlight the importance of further research and illustrate some of the ethical dilemmas wrapped up in this topic. Your chemistry teacher could contribute background on why isotope ratios can be used to infer changes in Earth’s air temperature over time.

If your district has a computer science program, those teachers can provide examples of some of the sophisticated models used to predict weather and associated climate trends. If you don’t have access to a computer science teacher, a calculus teacher should be able to describe how the models are built. If you’ve got access to a technology lab, you could work on designing and building weather instruments. If you have students who are interested in engineering careers, you could have them investigate the emerging fields of climate engineering and terraforming, which may be used on Mars to make that planet more habitable for people in the future.

There are a number of ethical issues involved in geoengineering and terraforming, and involving English teachers or social studies teachers with an interest in ethics would enrich STEM lessons on climate change. Hard choices may need to be made in the future to ensure our sustainability as a species. Addressing the ethical issues up front will help everyone involved make the best possible decisions. The effects that human activities have had or will have on global climate change are open to debate.

NSTA Legislative Update: Negotiations Continue on ESEA Rewrite

text-based graphic for NSTA legislative updateBipartisan negotiations continue between the two education leaders in the Senate. Senators Lamar Alexander (R-TN) and Patty Murray (D-WA) have issued a statement that they indeed intend to release their bill to rewrite the Elementary and Secondary Education Act (No Child Left Behind) the week of April 13 (Congress is now off for their two week Easter break). Both are committed to a bipartisan process for the bill, but Senator Alexander has indicated that addressing early childhood programs in the ESEA—a huge priority for the Administration and Senator Murray—will be difficult. At the center of negotiations are the issues of accountability and testing. STEM advocates are continuing to work with offices on both sides to get STEM-specific funding and programs included in this Senate bill.

In the House, Chairman John Kline is working to whip up more Republican support for his ESEA bill, the Student Success Act, after the bill was pulled from the floor following the loss of support from key conservative groups who thought it did not go far enough to erase the federal footprint from K-12 education. On March 24, the Washington Post reported that Kline was still a few votes short to pass the bill.

The bottom line is that STEM is becoming increasingly lost in both House and Senate legislation to reauthorize this federal education law.

Now is the time for educators to contact their members of Congress immediately, and ask them to make STEM education a national priority. At the Legislative Action Center of the STEM Education Coalition website, you can send a letter to your elected representatives, asking them to

  • Maintain a strong focus on science, technology, engineering, and math (STEM) education.
  • Continue the focus on math and science as required elements of any state’s accountability system.
  • Provide states with dedicated funding to support STEM-related activities and teacher training.

We need your help getting this message heard and to get as much support as possible for science and STEM education. Please take a moment to write to your elected officials, and send this message to your networks.

And finally, the White House Science Fair was last week. In case you missed it, here is a link to get you caught up. During the event, the President announced new corporate pledges made under the Educate to Innovate initiative. Congratulations again to the teams from ExploraVision and eCYBERMISSION who participated in this year’s White House Science Fair!

Stay tuned and look for upcoming issues of NSTA Express for the latest information on developments in Washington, DC.

Presentation options

millerblog504One of my goals is for students to communicate what they’re learning in science through presentations. For many of my students, traditional oral reports are overwhelming. I’m looking for authentic, less stressful alternatives.    —T., Oregon

One year, I assigned every student a 5-8 minute oral report on a science topic that interested them. I thought I was doing a good job by sharing a template and rubric for the presentation and providing class time for students to prepare. It took several class periods for all of the presentations, and even then some students were not ready. There was a comment sheet for audience members to fill out, but I wasn’t sure the students were engaged enough to justify the time and effort.

So I revisited the original purpose of the assignment to provide opportunities for students to communicate and share what they were learning. This is an authentic goal; most scientists write reports and give presentations at conferences, to potential sponsors, and to the public. It also can be an effective assessment strategy and aligns with the Next Generation Science Standards Science and Engineering practice of “Obtaining, evaluating, and communicating information.”

From my own experience as a presenter, I knew many presentations are done as a team or panel. Most include visuals and use different formats. Some are straightforward lectures; others have activities for participants or opportunities for discussion. I questioned which was most important for my middle schoolers—using an assigned format or engaging in the process of communicating their interests and enthusiasm.

I asked my students how to make this a better experience. They were brutally honest! They wanted to have a choice of formats, work with a partner, and use their creativity. I learned that for some students (for example, English language learners and those with anxiety issues) getting up in front of the class may not be a positive experience, but they still have a lot to share.

So the following year, during a unit on invertebrates, students did presentations in their choice of format, demonstrating something they learned or were excited about. I realized the variety of media and formats made it impossible to use a traditional rubric. But my students did not disappoint!

Meet the People Behind the 2015 NSTA STEM Forum and Expo

The 2015 NSTA STEM Forum and Expo is happening next month in Minneapolis, May 20–23. This unique, STEM-focused event is where informal and formal educators gather to share tools and resources that contribute to successful implementation of STEM education into schools and communities. What makes this so different from any other event of its kind? The people! So here’s a peek behind the scenes at just a few of the people who are collaborating to organize this year’s forum.

STEM Forum committee member Doug PaulsonDoug Paulson (the home town hero in this bunch!) is a STEM Specialist, Division of Academic Standards and Instructional Effectiveness, in the Minnesota Department of Education.

“I am thrilled to welcome NSTA and the STEM Forum to Minnesota, home of innovations such as pacemakers, post-it notes, and most recently, the first personal jet. In addition to the awesome sessions, come and hear from the next generation of Minnesota innovators on the Saturday student panel!

 

NSTA STEM Forum committee member Jennifer WilliamsJennifer C. Williams is the Department Chair Lower School Science at Isidore Newman School in New Orleans, LA.

“I’m looking forward to the excellent slate of presenters dedicated to helping primary educators develop STEM programs for their schools and their classrooms.”

 

STEM Forum committee member Kavita GuptaKavita Gupta is a High School Strand Leader in the Fremont Union High School District in Sunnyvale, CA.

“As a 16- year veteran of teaching profession , I think STEM is the future of education. NMSI (National Math + Science Initiative)  underscores the need of STEM education, ‘The U.S. needs 1 million more STEM professionals over the next decade than it is projected to produce at the current rate.’ We need to align with the STEM education to fulfill this need. I am really excited for the high school strand of  STEM forum this year because we have a wide-variety of rich STEM-based lessons for high school teachers, administrators and science liaisons– handpicked from over 100 outstanding  proposals.”

 

STEM Forum committee member Adrienne GiffordAdrienne Gifford is the Innovation & Technology Lab Director at Open Window School in Bellevue, WA (in addition to being a robotics coach and crafter); and she is the Steering Committee Chair for the 2015 STEM Forum & Expo.

“As a former aerospace engineering major, I am SO pumped to see the keynote by Captain Barrington Irving—the youngest person to ever fly solo around the globe! It is so inspiring to have the chance to see someone my own age pursuing their dreams and having such a positive influence on STEM education at the same time!”

 

 

NSTA Assistant Executive Director of Conferences and Meetings, Delores HowardDelores Howard is the Assistant Executive Director of Conferences and Meetings at the National Science Teachers Association.

“When I see teachers coming together and sharing their best ideas and supporting everyone from the newbies to the people making decisions at the highest level, it reminds me how lucky I am to be tied into this fantastic network!

How Do You Captivate with Current Events?

St. Thomas- August 08 145Today is March 22nd which can mean a variety of things to a variety of people.  It’s close to the beginning of spring this year; it’s in the middle of March madness, and it is also World Water Day.  According to the World Water Day website, this day is “It’s a day to celebrate water. It’s a day to make a difference for the members of the global population who suffer from water related issues. It’s a day to prepare for how we manage water in the future.” While the website has a variety of resources and materials other resources that can be utilized include the following which also appear in this month’s Leaders Letter.

While this day is important, it is not the topic of this month’s blog – rather the topic is “which current events do you integrate into your curriculum and how do you do so?” is the topic.

In recent months, the Leaders Letter has featured the following topics in the “Building Content” area:

Each of these topics focused on a current event in the news and the application of science to helping solve a problem, investigate a phenomena, or understand what is happening in the world.

Current events often bring the science students are studying to real life and create an interest to explore in more depth and understand more about what is happening, as well as, the science behind it. Current events can be obtained from print, social or digital news sources (and a recommendation is to always verify through multiple sources especially if something is obtained online) thus allowing news to be almost at your fingertips.   Discovery News actually has a listing of science topics tagged “current events” which may be of help in finding reading materials for students about a variety of current topics.

Where and how you find the current events topics is part of this question but also what do you do with the topic once found is the second part?  Do you utilize a current event topic at the beginning or end of class? Keep a certain day of the week for these topics? Hold the topic until it appropriately fits into your curriculum?  Share your ideas with others as you continue this month’s conversation.

A View of #NSTA15 from Down Under

international science teacher delegationAs soon as I saw the space that was allocated for the NSTA conference I knew I was in for something special. To have such a large convention centre dedicated to various forms of professional development over four days is a credit to the American science teachers and the National Science Teachers Association (NSTA), who took the time to put the workshops on.

The vast choice of workshops available meant there was always a new learning opportunity either on something specifically relevant to my teaching, or something that I was interested in learning more about. The presenters were confident and inspiring, encouraging high standards in the classroom. It is apparent that with the implementation of the NGSS, teachers in America are becoming more willing to think beyond the textbook and incorporate skills that are able to be applied to all facets of life beyond the classroom.

Moving from Textbook to Reality

As STEM becomes more prominent in Australian schools, I feel confident that I can up-skill my colleagues’ approach to their teaching and assist them in constructing lessons and units that engage students with real-world experiences, developing their global competitiveness for the jobs of the future. To have such an amazing educational event keynoted by someone as inspiring as Bill Nye seemed to bring the entire audience together, and perhaps reignited a passion for some teachers encouraging them to be the best they can.

Further to this, the resources available both in the NSTA store and the trade displays are going to greatly assist my lesson development as I have been exposed to data I didn’t know existed. I spent way too much money on books at the NSTA store and if it wasn’t for the weight limit on my flight home I would have bought a lot more. The digital resources that I have discovered thanks to both workshops and trade displays are amazing, and they are going to assist me in bringing global data to the classroom. I have already started to share these with my colleagues back home and I am excited to incorporate them into my teaching programs.

I am very thankful for this experience, and appreciate how welcoming all the NSTA staff were, and all the effort they went to to make the experience worthwhile. I look forward to the strong partnerships that have been forged with the Australian Science Teachers Association and though I may never be fortunate enough to attend another NSTA I will always remember the passion I saw in my international colleagues and I will use that as inspiration create relevant, supportive environments for science education.

Today’s Guest Blogger is Ashley Mulcahy, Glenwood High School, Science Staff, Foreman Avenue & Glenwood Park Drive, Glenwood New South Wales 2768

Editor’s Note: NSTA is grateful for this international view of our conference and learns so much from those beyond our borders. Thank you, Ashley! Should you ever require a member of the NSTA social media staff to attend an Australian conference, don’t hesitate to ask…

Crosscutting concepts

Themes, big ideas, unifying concepts—as the editor of Science Scope writes, the idea of crosscutting concepts in science is not a new one. (See the guest editorial Interdisciplinary Science: A Fresh Approach From the Past in Science Scope) But what is new in the NGSS is how the concepts integrate with science/engineering practices and disciplinary core ideas and also transcend grade levels and traditional subject areas. Many of us teachers are (or have been) challenged to connect these three dimensions in a planned and purposeful way. Fortunately for us, the NSTA journals each month provide examples and suggestions.

Building NGSS Capacity at #NSTA15

NGSS Forum collageThe 2015 NSTA National Conference on Science Education (held in Chicago, March 12-15) was a great opportunity for educators to build their capacity for understanding and implementing the Next Generation Science Standards (NGSS).  In Thursday’s featured presentation (The Key to Implementing the NGSS? Teachers!), Dr. Stephen Pruitt described this capacity-building journey as a path toward expertise: gaining knowledge but also pairing that knowledge with the information on how to use it.  In Chicago, NSTA offered NGSS sessions for everyone, covering the spectrum of experience with the Next Generation Science Standards.

2015 National Conference Learning

In Thursday’s Featured Presentation, Dr. Pruitt described three key innovations of the Next Generation Science Standards–3-Dimensional learning, the shift toward students being engaged in explaining phenomena and designing solutions, and the integration of engineering with the nature of science. The conference offered over 350 sessions to learn about these key innovations and move the standards into practice. Conference attendees had opportunities to learn from the NGSS and Framework writers, science specialists, post-secondary researchers, and classroom educators.

On Friday NSTA hosted a series of presentations called the 2015 NGSS@NSTA Forum. Dr. Joe Krajcik facilitated one of my favorite forum sessions (Developing and Evaluating Three-Dimensional Curriculum Materials). During our time with Dr. Krajcik, we were immersed in NGSS experiences involving models, reflection, table talk, metacognition, and practicing all the elements of expertise. An important take-away for the group was that this “figuring out” using all 3 dimensions  by explaining or creating a model continues to build throughout the lessons facilitating the deep understanding of science.

Many of the NGSS “rock stars” describe the result of NGSS learning as creating a complete picture for the student as opposed to presenting the student with discrete pieces of information.  There were so many wonderful NGSS-focused sessions presented by teachers sharing how they are translating NGSS into classroom teaching and learning. For example, Jaclyn Austin and Emily Perry shared their Stormwater Literacy Project as part of the Natural Resources, Natural Partnerships strand incorporating the NGSS and helping students use the science they learn to impact change. The NGSS share-a-thon session on Saturday morning brought together a room full of NGSS resources and opportunities to impact classrooms.

Post-Conference Learning

A critical element to any great professional learning experience is the opportunity to put new learning into practice and reflect on product and results, as well as find on-going support.  For those new to the NGSS, Achieve announced the release of a series of videos around the NGSS developed in partnership with the Teaching Channel.  Educators can use these videos to continue learning about the three dimensions of the NGSS and how they work together.  For those ready to design NGSS lessons and units or to evaluate existing materials to see if they are NGSS aligned, the EQuIP rubric developed in a partnership between NSTA and Achieve is a tool to encourage reflection and conversation among educators working together to develop and evaluate instructional products.  The NGSS@NSTA Hub is a one-digital destination to support teaching and learning of the Next Generation Science Standards.  NSTA offers more than 80 resources (not counting their journal articles)  to support teachers in understanding the NGSS and implementing the standards.

Man and woman holding a sign saying NGSSBlogs ProjectIn addition to resources and tools, educators need opportunities to have conversations and share ideas, stories, and curriculum.  As the NGSS featured presentation title indicates, the key to implementing NGSS is teachers.  Every teacher has a story to share and should be a part of the national conversation and work building curriculum around the NGSS.  There are rich communities like the #NGSSchat PLN (Professional Learning Network) and the #NGSSblogs Project that offer ongoing support, conversation, and opportunity to share and receive feedback about the frontline implementation of NGSS:  the science classroom and the programs and PD that support it.  There are multiple ways to access and join #NGSSchat and the #NGSSblogs project.  Learn more at http://www.ngsspln.com/.

Moticam X

 Moticam X

moticam

We live in an age where iPads and cell phones are part of the everyday fabric of high school life. With this being the case, Motic’s Moticam X has a great deal of promise as a scientific instrument that can connect a classroom microscope to a variety of portable technologies. As an added bonus, the Moticam X allows you to stretch your science budget by putting students’ personal devices to use instead of investing in a classroom set of new technology. The kit includes:

 

  • A focusable lens
  • Variable size eyepiece couples
  • Removable mini-USB cable
  • USB charger
  • C-ring
  • Macro-tube
  • Motic calibration slide with 4 circles and cross hair
  • Motic software and free apps for tablets

 

The Moticam X is a digital camera that can be used on its own for macro images or attached to the eyepiece of a microscope. Once in place, the digital camera streams high-resolution images to wifi-enabled devices such as  smart phones, tablets, and laptops. The Moticam X device can stream images to up to six different devices at the same time, which is excellent for a typical lab station sizes. The streaming image is 1.3 megapixels, which is appropriate for viewing on screen.

The procedure to set up the Moticam X is very straightforward. First, prior to attaching the Moticam X, I focused a microscope on a prepared slide. Next, I attached the Moticam X to the eyepiece of my microscope using a coupler that comes with the device. (If you prefer, you can attach the Moticam X to a goose-neck clamp and use it without the benefit of the microscope’s magnification.) Once the Moticam X was in place, I connected my iPad to the Moticam X by searching for it under the list of available wi-fi connections under the Settings tab. Once I established this connection I launched the app associated with the device and was able to view the slide on which the microscope was focused The device comes with software to help you connect to other wireless devices your students might be using. A router is not required.

 Users can view live images, but can also save images to their portfolios. They can then use the apps image editing tools to modify, annotate, and share images. The app also comes with camera settings that allow users to make adjustments for lighting conditions (fluorescent, daylight, LED, etc.) and change the brightness, hue, color saturation, and other basic settings. You can also flip and mirror the image using the camera controls

 Overall, I think this is a first-rate device that enhances the capabilities of a microscope and facilitates lab work. In addition, students can save images on portable devices and refer to them when completing homework and other assignments outside the classroom. The Motic X is a reasonably priced and well-built device that enhances the applications of microscope viewing by integrating Wi-Fi applications to connect microscopes with modern technologies. Undoubtedly, this is the kind of the application that will help students use technology for learning and give them an opportunity to collaborate outside the classroom.
