We are still having great fun blasting our water rocket high into the air. So far, we've only had to retrieve it from the neighbor's yard once. But, while we had the hose on, and our minds turned to Newton and his 3 Laws of Motion, I thought we'd take on a simpler experiment, for the younger kids.
I had T fill a bucket part way with water, and demonstrate to the little ones how the water would spill out, pulled by gravity, if he tipped it over.
Then, much to their amazement, they watched as he spun the bucket, in quick circles, up and over his head, without getting wet.
I explained to the little ones, that the water was in motion, and wanted to keep moving in a straight line, through the bottom of the bucket (Newton's 1st Law of Motion). So, even when the bucket is upside down, and gravity is pulling the water out, the force of the motion, keeps it pressed against the bottom of the bucket.
I tried to get T to demonstrate what would happen if he stopped the bucket above is head, but he remembered enough about the lesson from when he was younger, to refuse.
If you do this experiment with your own children, remember to use a bucket with a sturdy handle, or you will end up inadvertently demonstrating centripetal force, instead.
It's great to be a homeschooler.
