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.

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

In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

Learners classify a variety of objects by their characteristics. They then design an experiment to determine which objects float or sink in water and add this characteristic to their classification.

Focus sound through a balloon! In this Exploratorium activity, you'll use dry ice to create a balloon that's a sound lens.

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

In this physics activity, learners will explore buoyancy.

Experiment with liquids of different densities and create liquid layers. For example, oil and water have different densities: oil floats on water because it is less dense than water.

Learners measure a bottle full of air, and then use a vacuum pump to remove the air. When they re-weigh the bottle, learners find the mass is about 0.8g less.

In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

Making liquids of different densities to perfectly lay on top of each other can be a frustrating exercise. The Exploratorium created this activity as a fool proof way of making a density column.

It's difficult to see convection currents in any liquid that's undergoing a temperature change, but in this Exploratorium Science Snack, you can see the currents with the help of food coloring.

In this activity, learners will use cereal to conduct an experiment and investigate how decreased bone density is related to increased risk of bone fracture.

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.

In this activity, learners create a kind of balance device using a wire coat hanger, some string, and paper cups.
