The three things that I learned in this lesson was I learned that our houses are heated by convection. I also learned that when two things come in contact it is called conduction and I learned that heat rises when it is hot and it goes to the ground when it cools. My favorite science lab was the one when we had to see if the green food coloring moved or stayed the same. I mostly liked every thing in this lesson because it was fun to learn and try different things. One thing I didn't understand to well was how radiation worked or what it did.
