I’m really enjoying the fact that we are discussing energy so early in the year. In unit two, we covered how temperature worked when a substance did not change state. Now we are preparing to add the concept of phase energy. We need to explain why different substances exists in different states at the same temperature. This is where phase energy comes in. To prepare for this discussion, we need to understand that energy is always conserved.
To do this, we reenacted the Eureka video about heat and temperature. We then whiteboarded and discussed it. Take a look:
