In small group, read the book, What Is A Scientist by Barbara Lehn. Explain to the children that they are going to be scientists and will find out what actions can produce heat. Give the children a small wooden block and sand paper. Have the children put on goggles and sand their wooden blocks as fast as they can. As they sand, ask the children if they notice any changes to their wood. Have them touch their block to feel the surface heat. Talk about friction and how two objects that rub together really fast can cause heat.
