TED.com provides “Riveting talks by remarkable people, free to the world,” as videos (streaming, downloadable, podcasts, etc.) captured during the conferences. TED stands for Technology, Entertainment, and Design. Here are some of my favorite TED videos, and this list corresponds to the list published in our Science 2.0 column this month along with a few [...]
YouTube is an amazing resource, with videos on just about any topic. There are animations, videos of demonstrations that you might not be able to do in your classroom, and records of talks by famous scientists. The SciLinks webwatchers have been including them as teacher resources in SciLinks for several reasons: Some of the comments [...]
All you earlybirds out there are in for a treat this month if you look eastward just before dawn (and the weather is clear). Four planets will be engaged in a slow-motion dance, aligning themselves differently day by day in a tight segment of the sky. NASA has created a nice video describing the phenomenon:
The last few days of the school year are a challenge—the time in between the final projects/assessments and the last day of school. Students assume that the year is over, and to stay “busy,” they are sometimes inundated with videos or word puzzles. I often used this time for science activities we didn’t get to [...]
In the video above, a third grader gets to use a rather striking example of 21st century technology to talk about some common topics in science, namely earthquakes and volcanoes. As was mentioned in this blog before, back at the 2009 National Science Teachers Association’s national conference, Arne Duncan mentioned in his keynote that, “You [...]
How does a tomato go from green, marble-like sphere to juicy red brilliance? Chemistry, that’s how. In the case of tomatoes, the plant bathes the fruit in ethylene molecules when the fruit reaches an edible size, and this hormone triggers the fruit to ripen. We are into week eight of the weekly, online, video series [...]
Here’s a taste of NSTA San Fran. More on this later, but many of the tech tools are open-ended allowing for student/teacher defined uses. Overall, the future looks like a fun place to teach!
One thing about attending a NSTA conference, you get to try local cuisine, as well as an occasional unusual treat. I just spoke to this teacher from Pittsburgh who told me he sampled a scorpion in the exhibit hall. The chef didn’t recommend any sauces so as not overwhelm the scorpion’s natural flavor. It also [...]
It’s been a busy morning at the national conference. Although the exhibit hall didn’t open until 10 a.m., many sessions started much earlier. I had to chance to talk to some attendees between sessions and it sounds like everyone is looking for something a little bit different, but all with the same goal—to be a [...]
I must admit I’m a fan of mystery novels—from Nancy Drew to Sherlock Holmes, from Agatha Christie to Tony Hillerman. I enjoy trying to follow the clues and the thinking process of the protagonist. In contemporary stories (and TV programs), it’s also interesting to see how science is part of the investigation. The interdisciplinary activities [...]
