understanding frame of reference, measuring speed and velocity, observing acceleration caused by gravity. I'm not sure why I don't have pictures of any of the experiments. ?
We skipped a few things that seemed like they'd be too hard to do. We didn't do the second half of the frame of reference because we didn't have a wagon big enough to put a person in; we also skipped the relativity poster in lesson 20.
In unit 4, we started exploring dynamics (laws of motion, gravity, falling bodies) by observing inertia.
|When you flick the card, the coin drops straight down into the cup due to its inertia.|
We explored the second law of motion,
experiencing the third law of motion,
and played with gravity.
|Her design was unsuccessful.|
|Tenor's design: 4 small, inflated balloons in the bottom of the box; the egg wrapped in bubble wrap; 4 inflated balloons attached to the corners of the box|
determined whether mass affects how fast things fall,
and understood center of mass.this balancing bird instead.
We also skipped the green experiments in lesson 21 and lesson 23.
