Focus: Science and Art

Evaporating Art: Experiment to see how sun, shade, and wind affect how water evaporates. This activity works best on a warm, sunny day.

Materials

  • Paint brushes, sponge brushes, or sponges
  • Bucket or open container to hold water
  • Water
  • Pavement or stone (playground, driveway, sidewalk, or large rocks )

Directions

  1. Dip a brush or sponge into the water and paint a picture on the pavement in a sunny area.
  2. Ask the child to predict what will happen in 5 minutes to his picture.
  3. “Act out” evaporation with your child. Have him follow along with you. Crouch down and explain that you are all the water molecules in his painting. Next, explain that the sun comes out. All the molecules “getting excited” and “jumping” into the air. As you say this, stand up and jump into the air with your arms extended up and say “evaporate”.
  4. Ask him the following questions:
  • What do you see?
  • Describe what is happening to the water.
  • Is the water soaking into the pavement?
  • Is some of the water evaporating? How can you tell?
  • What do you think your painting will look like in _____ minutes? (Select a time you feel is reasonable here)
  1. Repeat the steps above, but have them paint a picture:
  • on the same surface in a shady area.
  • on the same surface in a shady area, but have him blow on it or fan it.
  1. Ask him what happened to the water painting. Discuss the differences he saw between his paintings when in the sun, when in the shade, and when he added wind.

Extension

  1. Have the child paint on the back of his hand or on his arm.
  2. Have him blow on it or fan it.
  3. Ask him the following questions:
  • What is happening to the water?
  • How does your hand/arm feel differently?
  1. Explain that when water evaporates that heat escapes with it. This is why it feels cooler when the air made contact with it. This is also why when you come out of the bath or shower that your body feels cooler. As the water on your skin evaporates, some of your body’s heat goes with it.
  2. You can continue to experiment with different surfaces (pavement, siding on the house, a toy) to see what happens to the water.
