All three journals this month include the inaugural Best STEM Books for Students K–12 with descriptions and reviews. The rubric and criteria used in selecting these books is also provided. Share it with your librarian, too.
Crowdfunding for Elementary Science Educators in S&C has fund-raising ideas applicable to any grade level.
Science Scope — Water
From the chemistry of water to the biology of water habitats and ecosystem to the relationship of water and weather to the importance of water in the body to current events related to access to clean water, water is indeed an Essential Substance.
Featured articles that describe lessons include a helpful sidebar (“At a Glance”) documenting the big idea, essential pre-knowledge, time, and cost. The lessons also include connections with the NGSS.
- Supporting Student Understanding of Watersheds by Using Multiple Models to Explore Elevation shows how a variety of models and maps can help students understand the flow of water in a watershed and its relation to elevation.
- If you are looking for a context in which to help students understand the concept of systems, take a look at Learning and Applying Systems Thinking When Studying a Local Creek System. The article includes student diagrams.
- From Fish Tank to Fuel Tank: Engineering Photobioreactors in the Classroom describes a multidisciplinary activity in which students grew algae as a potential source of renewable energy.
- Water, Water, Everywhere! But Is It Clean to Drink? Applying Engineering Design to the Challenge of Water Purification takes a problem-solving approach to this topic.
- The 5E lesson in An Inquiry Lesson on Stream Ecosystems shows students how the distribution of aquatic macroinvertebrates relates to the characteristics of a stream. There are suggestions for modifying this investigation if you aren’t near a stream, too.
- Science on a Shoestring: Testing the Waters includes directions for making and using a mini Secchi disk to measure water turbidity.
- With the Citizen Science: Citizen Science for a Rainy (or Snowy) Day project, your students can contribute to a national database of precipitation data, which can be used by the National Weather Service, NASA, USDA, researchers, and emergency management.
- Disequilibrium: Sticking Together has a 5E lesson on the cohesive properties of water.
- Teacher to Teacher: Designing the Water Treatment Process has a timely lesson on creating and testing models of treating water.
- Find ideas and suggestions from other teachers in this month’s Listserv Roundup: Teaching the Water Cycle.
