In this activity, learners are asked to examine the differences between two materials in a pair.

Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.

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.

Learners observe and compare the sizes of three toy “growing” crocodiles made from water-absorbent polymers. One is it its original state, dry, hard, and about 10cm long.

This is an activity about the behavior of light. Using simple, everyday objects, learners will discover that light moves in straight lines until acted upon by another object.

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 chemistry activity (on page 2 of the PDF), learners make a layered drink with liquids of different densities.

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.

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.

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.

In this activity, learners will be introduced to biomass gasification and will generate their own biomass gases.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

In this physics activity (page 12 of the PDF), learners explore potential and kinetic energy by rolling different sized marbles down an inclined plane.

This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

Learners design their own experiment to determine which M&M color dissolves the fastest in water.
