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 activity, Frankenstein's lab is running out of electricity! Learners use fruit to help Igor find a temporary source of energy to turn on a light.

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

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

In this simulation, learners explore how ocean currents spread all kinds of pollution—including oil spills, sewage, pesticides and factory waste—far beyond where the pollution originates.

In this activity, learners make optical fibers out of strips of gelatin.

In this activity, learners use detergent solution to compare two solutions containing vinegar and cream of tartar.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

Learners make their own acid-base indicator from red cabbage. They use this indicator to test substances around the house.

In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

In this activity, learners explore how packaging engineers develop customized shipping and packaging containers to meet the needs of many different industries.

Learners carefully look at four known household crystals.

In this activity, learners discover how gelatin can be used as a medium for drug delivery. Learners create colored gelatin and then cut out pieces of the gelatin to simulate medicine (pills).

Each learner chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days.

This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.
