In this science fair project, young children discover what happens when two fluids that have different densities get together.

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.

Is it solid or liquid? Create oobleck and witness the amazingly weird oscillation between the two!

Put a twist on traditional oil painting with this fun science activity that you and your first grader can do together.
