We had more fun with Newton's Laws of Motion today, pulling an experiment from Janice Vancleave's Scientists Through the Ages.
I prepared things ahead of time, by cutting one of the narrow sides off of an empty cereal box, and taping it into a loop.
Then, we balanced the loop on top of a jar, and placed a penny on top of the loop.
The kids took turns rolling the loop off the jar, with a pencil...
...and watching the penny drop into the jar.
It fell straight down every time. We repeated the experiment, replacing the penny with lighter objects, like a googly eye, or a paper clip, and it still worked every time.
I asked the children if they knew why the penny dropped into the jar, instead of moving forward with the loop. My oldest didn't miss a beat in telling me it was because of on of Newton's Law thingies - an object at rest wants to stay at rest. The others nodded in agreement, and added that gravity was pulling it down, too.
They've been listening! I think I managed to keep the evil laugh inside my head, though they might have noticed the happy dance in my eyes.
It's great to be a homeschooler.
