#Teach180 Day 61
AP learned about Kepler's Laws and derived the third one. They worry about it not being on the equation sheet until we derive it for a circle.
Physics did a max force lab, making use of string that I was gifted that falls apart very easily. Continuing to reinforce Fnet vs others.🎢🧪

Physics continued exploring Newton's Laws without calling them that with the blocks & bands activities. They have similar blocks, some with hooks and some without that they attach to rubber band chains. Lots of prescribed experiments but they also do their own. 🎢🧪

#Teach180 Day 15:
AP Physics worked through a review slide deck in partners for forces covering everything from units to vector addition to FBD, conceptual scenarios, etc. Great discussions if they engage with it. It includes this inertial reference frame question i mocked up: 🧪🎢

Even with fresh batteries this one wont work ... I think its time it goes to the toy car junk yard. 🧪🎢

Knitting hats on my knitting machine led to some charge build up apparently. This was after the first time or two I couldn't even get the cut end to go into the tube at all. #ITeachPhysics 🎢🧪
