This week in science, we focused on learning about how to create a hypothesis and how chemical changes can cause energy to be created. We learned about how all matter is made of particles and is either a solid, liquid, or gas. Students began Monday by creating a group hypothesis, after we observed what happened when water was added to a mystery solid substance, and what we think should be combined to have the largest transfer of energy in another trial on Tuesday. There were some explosions on Wednesday!
