Heat and Matter!!!

After discussing energy and temperature in science, it was time for a science lab. Yesterday we used a balloon, safety goggles, a yard stick, string and a heat source to demonstrate how temperature increases when you add energy. After our experiment each student had to write a journal to explain how heat affected the size of the balloon and what happened to the air particles in the balloon when it was heated. I think we may have a few future scientists in fourth grade this year. :)
