Why Should I Teach Science in Early Childhood Education?

Science is an important subject for all students, and it is especially important for young children. Science helps children understand the world around them, and it provides them with critical thinking skills. In addition, science is a lot of fun!

What Does Science Look Like in Preschool?

You DON’T have to be intimidated by science!

People often think of science as being difficult, but that doesn’t have to be the case. Kids are natural scientists because they love exploring. The best way for a 3,4, or 5 year-old to learn science is through hands-on FUN. A science center for preschoolers should be all about play and exploration.

What Should Preschoolers Learn in Science?

Here is a nice list of scientific topics that you can teach to preschoolers:

  • The five senses – We can constantly talk about what we hear, see, feel, and smell.
  • Seasons – The seasons are always changing and in many places, you can explore these changes with your senses.
  • Weather – Along with the seasons, the weather is always changing. Talk about this with your kids.
  • Plants – From trees, to lawns, and houseplants, kids can care for or observe changes in the plants in their world.
  • Animals – Kids LOVE animals! Talk about life cycles, adaptations, differences, what they need to survive, etc.
  • Life cycles – How to animals grow? What about trees and other plants?
  • The human body – From the five senses and germs to anatomy and growth & development, there are so many kids can learn about themselves.
  • Materials and changes in matter – Don’t get scared about this one. This can include things like talking about the water cycle (melting ice cubes), classifying objects by whether they are made of wood or plastic etc.

Nothing is intimidating there, right? These concepts are all very easy to teach with the right activities.
