Today we built a slingshot to help us understand energy. We learned that there are two main types of energy. One is potential which is energy waiting to be used. The other is kinetic which is energy in motion. We learned that potential energy changes into kinetic energy. We also learned that energy is constantly changing, but we can never make more energy than you use.
The energy used to propel the slingshot came from us. The energy we had came from the food we eat. The food we eat got its energy from the plants. The plants got their energy from the sun. The energy changed a bunch, and kept changing into something new.
