Can't make it to the beach? Bring the science of ocean waves home with this fun earth science-related craft.

Help your kindergarten scientist explore an important part of earth science: how soil retains water.

It's a rare kid who doesn't like a sandbox. Next time you're out digging, build in some earth science, too.

Children learn the six parts of a plant...but do they really understand? Try this plant-themed meal plan to bring school science into the home.

Kindergarten algebra is a lot different than high school. In kindergarten math, algebra means grouping like things, or noticing what doesn't belong in a set.

This fun experiment provides a concrete and visually striking illustration of photosynthesis.

This experiment challenges students to forecast the weather based on the surrounding areas' weather.

This project explores whether plants can live and grow when "watered" with juice, soda, or milk.

In this project children discover, identify, and sort seeds from a variety of fruits and vegetables

Create your very own scented hand sanitizer that will help your child to keep those nasty germs at bay!
