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 activity, learners explore how voting systems have changed with engineering advances over time. Learners work in teams to design their own voting system using easy to find materials.

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 activity, learners explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.

In this activity, learners train to increase muscular strength and improve upper and lower body coordination by performing the “bear crawl” and the "crab walk.” Learners perform the exercises over tim

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

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.

In this quick activity (located on page 2 of the PDF under GPS Wetlands Activity), learners will model how wetlands act as natural filters for the environment.

In this activity, learners create an origami model of DNA, demonstrating its double helix structure.

In this activity, learners will train to develop upper and lower body strength in their muscles and bones by performing body-weight squats and push-ups.

In this activity, learners explore how the pendulum has been a reliable way to keep time for centuries.

In this activity, learners explore the unique challenges in transportation engineering, such as devising a method for skiers or hikers to get to the top of a mountain.

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

In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.

Learners will build a homemade pump using a balloon, a mason jar, and some straws.

In this activity, learners explore how engineers work in a team to solve problems.

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