In this goopy activity (page 2 of PDF under GPS: Glaciers Activity), learners will model glacial movement with “gak,” a white glue and liquid starch mixture.

Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.

In this activity, learners examine the culture and history of the tomb site.

In this activity, learners create their own archaeological profiles.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

In this hands-on science experiment, students combine their understanding of the different states of matter and the characteristics of various chemical reactions.

This activity (located on page 3 of the PDF under GPS: Lava Flow Activity) is a full inquiry investigation into the relationship between an object’s mass and the distance it is thrown by a catapult.

In this activity, leaners explore building techniques by recreating the story of The Three Little Pigs.

This activity has learners observe water and compare it to other liquids.

In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.

In this activity, learners investigate visual perception as well as plan and conduct their own experiments.

In this experiment, learners try different liquids to see which ones clean pennies best. Liquids to try include water, lemon juice, cola, vinegar, and dishwashing detergent.

In this physics activity, learners build a toy with a figure that spins around like a gymnast on the high bar.

In this activity about human interface design issues, learners help the Oompa-Loompas of a great chocolate factory solve different problems.

In this activity (26th on the page), learners construct an easy-to-build device and test motor learning.

Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.

In this activity, learners investigate procedural memory.

In this activity, learners collect, categorize, weigh and analyze classroom trash and discuss ways that engineers have helped to reduce solid waste.

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.
