Preschool is an excellent time to introduce kids to science. There are lots of great science projects you can do with preschool students.

Preschool Science Project Tips

Above all, preschool science projects should be fun and interesting. They do not need to be time-consuming or complicated. The goal is to get preschoolers to ask questions and see if they can find ways of answering questions. Another goal is simply to get preschool students interested in science. Science projects at this level should be relatively brief, preferably accomplished within one session.

Preschool Science Project Ideas

  • Silly Putty - Have the preschool students play with silly putty. What are its properties? What makes Silly Putty different from other materials? Try to pick up newsprint with the putty. What happens to the image when you pull the putty in different directions?
  • Explore Color - Preschool students can explore how color works by predicting what will happen if different colors of finger paints are mixed or by seeing what happens when different colored filters are used to look at a light source.
  • Make a model of the Earth. Make a model of the solar system.
  • Model a volcano by making a baking soda and vinegar volcano.
  • Make a 'telephone' using empty cans and a string.
  • Fill a bowl or tub with water and have preschool students predict whether objects will sink or float.
  • Play with balloons and discuss how they work. Blow them up, rub them on your hair to produce static, see what happens when you let go of an open inflated balloon, try twisting balloons into shapes. If you have access to helium balloons, explore how helium is different from air.
  • Blow bubbles. Are bubbles always round? How do bubbles stack on top of each other. Make bubble prints.
  • Group foods into those preschool students think are healthy/unhealthy and discuss why the foods were placed in these groups.
  • Plasma Ball - Have preschool students predict what will happen when they touch the surface of a plasma ball. What happens when you use one finger? Your whole hand?
  • How many times can you fold a piece of paper in half? Does it matter what type of paper you use?
  • What do seeds need in order to sprout?
  • Flower Petals - Have preschool students take a close look at flowers. Have you ever counted how many petals a flower has? Most flowers have petals in multiples of 3, 4, or 5. Can you predict how many petals a flower might have just by looking at the leaves of the plant?
