Here's a fun activity to help build thinking skills in young first grade scientists, and to encourage them to have a blast exploring the mass and volume.

Your 1st grade scientist will improve her observation skills as she's encouraged to eat healthy by comparing the dry and fresh fruit in this experiment.

Satisfy your sweet tooth with this easy summer activity! Make homemade ice cream and let your child practice his science skills.

Did you ever think you could make colors disappear right before your eyes? This science experiment is just like a magic trick: now you see it, now you don't!

Water can go from solid to liquid to gas...but how does popcorn go from kernel to snack? Invite your first grade scientist to find out.

Make meringues with your first grader and see how states of matter can transform before your very eyes. Here's how:

Introduce your child to science with something they see everyday--their shadow!

First grade science often covers solids, liquids, and gases. This silly science explores serious facts about the difference between all three.

This project demonstrates the correspondence between the volume of water displaced by a submerged object and the volume of the object displacing it.

Explore the scientific concept of capacity by seeing how many pennies you boat can hold before it sinks!

Explore solids and liquids with your young scientist by making gluep, a goopy substance that can behave like both a solid and a liquid!

Help your kindergarten scientist discover relative size, density, and buoyancy with this fun, pumpkin science project!

Use reusable, recyclable materials--along with a dose of imagination--to build a castle with first grade geometrical forms.

This fun, think-outside-the-box activity introduces kids to gravity and other basic scientific concepts as they construct an impressive marble run!
