In this activity about the relationship between food and energy (page 1 of PDF), learners observe and quantify the growth of yeast when it is given table sugar as a food source.

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

In this activity, learners explore the concept of how engineering has made possible the development of--and ongoing improvements to--adaptive devices that serve to help individuals with a wide range o

In this two part activity, learners work in pairs or individually to discover how vectoring the thrust from a jet engine affects movement of an airplane.

In this activity (located on page 2), learners will construct tiny model geysers out of film canisters, warm water, and antacid seltzer tablets.

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

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.

In this activity, learners will engineer three different parachutes to test how well each one works.

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

In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

Learners use compasses to detect the magnetic field created by current moving through a wire. This is one of four activities learners can complete related to PhysicsQuest 2008.

In this activity (4th activity on the page), learners test to see if saliva is necessary for food to have taste.

In this activity (on pages 11-12 of PDF) learners create models of lava layers that have formed on the moon.

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

Many common household cleaners are antimicrobials.

In this activity learners explore surface tension. Why are certain objects able to float on the surface of water and how do detergents break the surface tension of water?

In this design challenge activity, learners build a four-stringed instrument that can play a tune.

In this activity, learners explore the devices used over time to measure changes in temperature.

In this activity, learners explore how engineers use scales and measures when designing a manufacturing process to ensure that final products are uniform in weight or count.

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