This is an educator-led demonstration of microarray technology using a model created from a pizza box and ping-pong balls.

In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this activity that can be used as a lab or demonstration, learners use Lactaid® and lactose to demonstrate the concept of enzyme action.

In this activity (page 10), learners explore how molecules self-assemble according to forces of attraction and repulsion.

In this quick and easy activity and/or demonstration, learners illustrate the effect of the weight of air over our heads.

In this activity/demo, learners are introduced to the connection between medieval stained glass artisans and nanotechnology.

Learners classify a variety of objects by their characteristics. They then design an experiment to determine which objects float or sink in water and add this characteristic to their classification.

This is a series of demonstrations about different electrical and magnetic phenomena.

This lesson guide includes six simple and quick activities to help learners better understand Bernoulli's Principle.

In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause

In this activity, learners explore how a hydraulic pump works. Learners work in teams to design and build a unique water fountain that employs a hydraulic pump.

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

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

In this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.

This magic trick is based on how computers detect and correct data errors.

In this interactive and informative group activity, learners use packages of M&M's to illustrate the difference between weather and climate.

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 demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and temperature inside

In this activity about the heart (on page 22 of the PDF), learners examine sheep or chicken hearts to learn about the heart's structure and the flow of blood through the heart.
