Tuesday: This is the conservation of energy lab that uses pendulums and photogates. We observed huge errors I’m unaccustomed to but the kids were great at describing sources of the error, so there’s that. Followed up with the Lewin pendulum video. Today, I put the lab first. I liked the result. Need to do that more often.

Monday: because we ran out of time Friday building our rubberband cars, I allowed the kids to finish building at home and we raced them in the morning. The pictured car easily ran the minimum 3 meter distance required of the project. Also this student had an ingenious way to create a spinning axle that’s held in place. He said this car was his fourth iteration. My feeling on this project is that it’s probably best to have kids build an published design and modify it. In the ninth grade the average kid simply don’t have the mechanical aptitude to design and build in a reasonable window of time.

Friday: In the morning, we tested our knowledge of forces and in the afternoon, built rubber band powered cars. I built alongside the kids and all of us struggled to construct an axle that spins and also stays in place. Mechanical aptitude isn’t our strong suit, I suppose. Ooh and the Supreme Court also announced its ruling on marriage equality Friday! My marriage is no longer illegal here in Georgia.

The pictured list is incomplete but at least it was generated by the students. Fun fact: this post was created automatically using a recipe I programmed on IFTTT.

#180blog Inertia: why does the table setting stay put when you yank out the tablecloth? Great question arose when the silverware kept falling off the table. Why? When we put it on the plate, the silverware stays there. Could it be that the silverware is too light? If the plate’s inertia makes it resist changes in motion, maybe the silverware doesn’t have enough inertia to stay put.
