Water Science Experiments for Elementary Students

When COVID hit, I became a homeschool mom overnight.  While I appreciated the worksheets our school sent home during the spring, my kiddo did not.  She is a hands-on learner.  So I started looking for science experiments we could do as a family to not only keep her excited about learning, but to also teach her about the world around her.

Here we share a few of our favorite “water tricks” that she has learned by doing these elementary water science experiments.

Science Experiment: What is Air Pressure?

Science Lesson
When a glass is pushed underwater, air is trapped inside.  The air pressure balances the water pressure outside.  The water compresses the air but cannot push past it.

Science Experiment: Does Water Climb?

Science Lesson
Water molecules can be more attracted to other substances than they are to each other.  The attraction enables water to travel a long way into some substances.  This is called capillary action.  Capillary action encourages water to climb up plants.  Plants allow water to evaporate from their leaves, which also helps to ‘suck up’ the water.

More Great Water Science Experiments for Elementary Kids

If you’re looking for more great elementary science experiments for preschoolers, kindergarten, and first grade students (heck, the book could be used for older kids, too), I highly recommend the Usborne Science Activities Volume 1 (or Volume 2) books.  They are fairly inexpensive, full of great ideas, and they have the science lesson to be taught easily explained.  We purchased these books to help us with homeschool science projects when learning went virtual during COVID.  Our daughter truly looks forward to picking out experiments to do in the book, and it’s good fun for the whole family.  All experiments on this page were taken from the Volume 1 Book, and the science lessons below each video are taken from the book, too.
