Is magnetism a source of green energy? Sort of. Magnetism by itself may not provide a new source of green energy. However, it’s clear that it could play a big role in lowering costs and improving efficiency for a number of renewable energy sources. Looking for educational activities for kids at home? Have some fun with exploring the cool properties of magnet science!
- Empty 2-liter bottle
- Pipe cleaners
- Strong magnet
1.) Cut pipe cleaners into smaller pieces (thirds worked best).
2.) Put the pipe cleaner pieces in the bottle.
3.) Use your magnet to manipulate the pipe cleaners. The kids all had fun moving them around in the bottle!
This floating ball game and classic toy by Schylling is a wonderful example of Bernoulli’s Principle, the same principle that allows heavier-than-air objects, like airplanes, to fly. As air is forced through the wooden pipe and around the ball, it must move faster in order to “catch up” on the other side. The result is a decrease in air pressure around the ball than in turn keeps the ball in place!
