Predicting the Meltdown


Crayola® Model Magic snowmen demonstrate your understanding of the different physical forms of water.


1. Discuss and demonstrate how water has three forms: solid, liquid, and gas. If possible, create a snow figure outdoors. Or freeze ice in molds. How long will it take the snow/ice to melt? How long will it take the water to evaporate? Under what conditions?

2. Work in pairs to create four or more Crayola Model Magic models: the solid form of water, intermediate melting stages, the liquid, and the scene after it evaporates (or melts into the Earth). Use Crayola Washable Markers to color any parts of the Model Magic sculpture.

3. Conduct experiments with snow, ice, water, and evaporated water. Predict how long it will take for real solid water (snow sculpture or ice) to become liquid. Estimate how long it will take for liquid to evaporate. Make labels on index cards with markers. Note the current date plus each team's date and time predictions for melting and evaporating.

4. Display the prediction models. Compare the predictions with what happens to the snow or ice. Consider why the predictions were accurate or not.

Safety Guidelines

Adult supervision is required for any arts & crafts project. Observe children closely and intervene as necessary to prevent potential safety problems and ensure appropriate use of arts and crafts materials. Some craft items, particularly beads and buttons, are potential choking hazards for young children. Avoid use of such small parts with children younger than 3 years. Craft items such as scissors, push pins and chenille sticks may have sharp points or edges. Avoid use of materials with sharp points by children younger than 4 years. Read all manufacturers' safety warnings before using arts and craft supplies.

Crayola Modeling Materials including Crayola Model Magic®, and Model Magic Fusion™, Crayola Air-Dry Clay, and Crayola Dough—

  • Keep away from open flames. Do not use to make candleholders, hot plates, trivets, or other similar objects that will be used or placed near fire and other heat sources.
  • Do not put in an oven, microwave, or kiln.
  • Do not make into vessels/containers that will hold unpackaged food.
  • The use of modeling material to make items that look like food is discouraged for children younger than age 5 to avoid their confusion with real food.
  • Unless sealed with a water-resistant glaze, do not make projects exposed to or immersed in water, such as boats or outdoor bird feeders. They would disintegrate when exposed to moisture.
  • Crayola Dough—contains gluten (wheat flour) as an ingredient.
  • Crayola Air-Dry Clay, Crayola Model Magic and Model Magic Fusion are gluten-free. However, they are produced on the same machinery as Crayola Dough which does contain gluten. Although the machines are cleaned prior to the start of each production run, there is a slight possibility that trace amounts of gluten from Crayola Dough may be present in the other modeling compound products. For information regarding specific ingredients or allergic concerns, please call our Consumer Affairs department at 1-800-272-9652 weekdays between 9 AM and 4 PM Eastern Standard Time.


  • Experiment with various melting conditions, such as indoors and out; heated, frozen, or refrigerated; moving or still air; insulated with newspaper; sunshine and shade. Observe and record all results. Compare to predictions.
  • Try the process in reverse. Predict how long it takes liquids to freeze. Or how long it takes gelatin to set. At what temperatures? In what types of containers or amounts?
  • Make ice cream, frozen juice pops, or frozen grapes for a healthy treat.
