Let's Warm Up!

 
Have you ever rubbed your hands together to get warm? Try it! Rub your hands together really fast for 30 seconds. They feel much hotter. Rubbing produces heat.
 
Try this activity to see for yourself.
 
Materials:
  • Paper clip
  • Assorted objects to test:
    • Craft sticks
    • Rocks
    • Socks
    • Blocks
    • Jar lids
    • Etc.

 
As you have seen heat is made by rubbing things together. Some objects produce more heat than others, but heat is always produced.
