In this activity, learners play a simple card game to learn the sequence of events in the transmission of nervous system signals.

In this activity, learners construct a simple game to test their hand-eye coordination and steadiness of hand.

Learners discover the bubble power of living cells in this multi-hour experiment with baker's yeast. Learners make a living yeast/water solution in a bottle, and add table sugar to feed the yeast.

Learners mix a solution containing luminol and copper with a fake blood solution. A chemical reaction between the luminol solution and fake blood (hydrogen peroxide) show learners a blue glow.

This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

In this activity, learners build models of atoms and molecules, then consider their role in different phases of matter, density, and mixtures and solutions.

In this activity, learners discuss the different salinities of oceans, rivers and estuaries.

In this activity, learners use a laser pointer and two small rotating mirrors to create a variety of fascinating patterns, which can be easily and dramatically projected on a wall or screen.

In this introductory demonstration and activity, learners are introduced to the concept of density as they explore a rock and a wooden block in water.

In this activity, learners discover how the extent of various wind speeds changes in each of the four quadrants around a hurricane.

Learners will see that changing the shape of an object, like a clay ball, that is more dense than water, can affect whether the object will sink or float.

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe.

In this demonstration, learners observe as a bottle is placed on a table with wooden hoop balanced on top and a pencil balanced on top of the hoop.

In this activity, learners confront their perceptions of gravity in the solar system.

In this simple activity, learners investigate refraction by placing a picture of an arrow behind a glass of water.

This is an activity (located on page 4 of the PDF under Surface Area Activity) about surface area and reactivity.

In this adapted version of poker, learners practice writing chemical formulas by playing this chemistry card game.

In this activity, learners make models representing bones on Earth and bones that have been in space. They discover what happens to bones without proper exercise and nutrition.

In this chemistry activity, learners use guar gum to make slime. Use this activity to introduce learners to polymers, viscosity, and colloids.
