Put your second grade scientist to work this Fourth of July with our colorful "liquid fireworks" project!

Your kid will be captivated as she watches liquids change color before her very eyes during this fun science project that introduces some chemistry basics.

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.

Test your friends to find out if you can replicate the placebo effect's incredible results.
