Why Is Science Important For Kids?

Kids are curious and always looking to explore, discover, check out, and experiment to find out why things do what they do, move as they move, or change as they change! Indoors or outdoors, science is definitely amazing! Holidays like Christmas just make science all the more fun to try!

Science surrounds us, inside and out. Kids love checking things out with magnifying glasses, creating chemical reactions with kitchen ingredients, and of course exploring stored energy!

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.

Helpful Science Resources To Get You Started

  1. Can you use anything in place of the Borax? I work in a elementary autism room and some of our students are very oral. They put their hands in their mouths quite often. I would love to make the crystal ornaments with them.
