Materials
- Warming tray
- 12 foil baking cups
- 2 ice cubes
- 2 peeled crayons
- 2 cubes of cheese
- 2 paper clips
- 2 pieces of wood
- 2 tortilla chips
- Chart paper and marker
What to do
1. Turn on the warming tray and warn the children that it will get hot. Supervise closely.
2. Hold up each item and have the children predict whether or not the object will melt. Record their predictions on chart paper.
3. Have children place one of each item in the foil muffin cups.
4. Place one set of items on a nearby counter or table and the other on the warming tray. For example, one ice cube would be placed on the table and one on the tray.
5. Have the children observe the two sets to see which ones melt and which don't. Discuss their observations.
