EASY SCIENCE EXPERIMENTS FOR KIDS!

HANDS ON SCIENCE ACTIVITIES

Kids are curious and always looking to explore, discover, check out, and experiment to find out why things do what they do, move like they move, or change as they change! My son is now 10 and we started around 3 years of age with simple science activities for kids. Here’s our very first experiment.

Read more about the scientific method for kids to help you get started.

There are lots of easy science concepts that you can introduce kids to very early on! You might not even think about science when your kid…

pushes a car down a ramp.
plays in front of the mirror.
laughs at your shadow puppets.
bounces balls over and over again.
fills up a bucket of water and dumps it out.

See where I am going with this list! What else can you add if you stop to think about it? Science starts early, and you can be a part of that with setting up science at home with everyday materials. Or you can bring easy science to a group of kids! We find a ton of value in cheap science activities and experiments.
