In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

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

In this activity, learners investigate the movement of water into and out of a polymer. Learners test the diffusion of water through gummy bears, which are made of sugar and gelatin (a polymer).

In this two-part activity, learners use everyday materials to visualize one mole of gas or 22.4 liters of gas. The first activity involves sublimating dry ice in large garbage bag.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity (page 18 of PDF), learners will measure the volume of impact craters created by projectiles of different masses.

This activity puts a mathematical twist on the familiar “guessing jar.” No guesses allowed, estimates only.

In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.

In this activity, learners explore how product design differences can affect the success of a final product -- in this case a bag for holding candy.

In this activity, learners will put a set of containers in order by capacity. Would the tallest container hold more or less water than the wide, short one?

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

In this chemistry meets cooking activity, learners compare the stability of egg white foams with various additives.

Learners make a counting/estimating jar to exchange with friends or bring home.

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

Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.

In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.

In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.

Learners act as engineers and design mini submarines that move in the water like real submarines.
