In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.

In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

Using a real-size sketch of a baby elephant's footprint, learners estimate, measure and record the width (diameter) and outside edge length (perimeter or circumference) of the footprint.

In this coin math activity, learners sort and stack 100 (one hundred) pennies into piles of 5 pennies each, 10 pennies each, and 20 pennies each.

In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this activity, learners write invisible messages on goldenrod paper, and make the message appear and disappear using acids and bases.

How many colors make black? Gather as many water soluble black markers as you can find.

In this interactive board game, learners "hire" different types of scientists to help canine character Ruff Ruffman solve unusual problems.
