…….As with many science topics, there are some wonderful children’s books about water; one of my favorites is Water’s Way by Lisa Westberg Peters. Share this book with your child to help develop his or her understanding about evaporation, condensation, erosion, and how water flows — through text and pictures that are designed for a young child’s reading level.
Place a small amount of water in a plastic bowl. Give your child a thick paintbrush and have him “paint” with water on a sidewalk at a park or on the concrete slab in your backyard. Talk about the
Buy an eggbeater or hand mixer at the dollar store. Have your child play with bubbles not just by blowing bubbles, but also by placing dish detergent in a large bin and using the beater to make lots and lots of bubbles, This will also promote hand coordination practice for your child!
Remember, you don’t have to be a science teacher to teach concepts like these to young children. All you have to do, really, is create or put them in an environment with interesting things to explore and objects to explore with, and then be as curious and interested in what they see, hear, touch and do as they are. Meanwhile, you will be planting seeds of understanding about physical science concepts that children will formally encounter in school before too long.
