1. Compare your predictions to what actually happened in the activity. How were your
predictions the same or different?



2. What do you think caused the color to change faster? Why?



3. What do you think would happen if you used different colors (for example, blue or
yellow instead of red)?


Write a paragraph describing something you witnessed in the last week that demonstrates how
heating or cooling affected a material (consider what happened in your kitchen, backyard, etc.).
