In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

This highly visual model demonstrates the atomic theory of matter which states that a gas is made up of tiny particles of atoms that are in constant motion, smashing into each other.

In this activity, learners explore how engineering has impacted the manufacturing of canoes over time, including the development of new, durable, and lighter materials.

In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.

In this activity, learners mix water, cooking oil, and liquid food coloring to create beautiful colored designs in a cup. Use this activity to explore liquid density and solubility.

In this activity, learners explore sports engineering and advanced materials development.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

In this activity, learners explore how hot and cold water move. Learners observe that temperature and density affect how liquids rise and fall.

The demonstration/experiment provides quick proof that air has mass.

In this activity, learners explore density, convection, stratification, and, by inference, the melting of icebergs. Learners make hypotheses, test their hypotheses, and explain their observations.

In this chemistry meets cooking activity, learners compare the stability of egg white foams with various additives.

Learners will understand the relationship between climate change and sea-level rise.

In this activity, learners explore what makes a boat float and sink. They examine and test various objects to determine why objects float or sink.

This fun video explains how to make a batch of oobleck (or slime) and why this special substance is known as a "non-Newtonian" fluid. Watch as Mr.

Get a roll of pennies, throw them on the ground, then remove those that only show tails, and repeat with the ones left over.

In this quick activity, learners explore static electricity using a plastic comb, wool cloth, puffed rice, and a plastic bag.

As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.

This is an activity exploring color and color mixing.

In this physics activity, learners will explore buoyancy.

Everybody loves bubbles, and this is the best bubble recipe ever!
