I almost forgot about my blog post today!
AP Physics: Ohm’s Law
We got out the power supplies and resistors to see if the formula students found for Ohm’s Law in the sim yesterday also works in the real world. Students were getting good results and I overheard a lot of good talk about uncertainty.
Earth Science: Earth’s Layers
Students worked on a scale drawing of the interior of the earth. I like students comparing the thickness of the layers and getting a sense of scale by adding some features like Mount Everest or an ocean trench. The questions are fairly superficial, so I need to think about what kind of deeper thinking I want them to do tomorrow. I do like the way the Mystery Tubes lead into this, since we don’t have any direct observations of Earth’s interior.
