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

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.

In this activity (2nd activity on the page), learners explore how the nose is responsible for part of the flavor we taste in food.

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.

In this demonstration, learners can observe a number of small convection cells generated from a mixture of aluminum powder and silicon oil on a hot plate.

Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.

In this activity (Page 22 of PDF), learners investigate the evolution of wheat by washing different types of dough with water and comparing the results.

In this activity (Page 25 of PDF), learners investigate the evolution of wheat by creating dough from different flours, observing the samples of dough as they rise, and then baking the dough.

Learners engage in close observation of falling objects. They determine it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.

In this activity, learners perform a simulated blood test procedure.

In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.

In this chemistry activity, learners explore density by using four solids and 6 liquids to create colorful, layered rows.

In this chemistry challenge, learners systematically investigate which combination of four solutions produces a deep red color.

In this activity, learners discover that atoms and ions of different metals will change places.

In this activity, learners explore how their depth perception would be affected if they only had one eye. Learners work in pairs and attempt to drop a penny in a cup with one eye covered.

Learners play the role of materials engineers as they test the flexibility of different materials.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.
