In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

In this physics activity, learners conduct two experiments to explore free-falling.

In this colorful activity (page 6 of the PDF), learners will make a multicolor density column by using different concentrations of sugar solutions.

In this activity, learners model the gravitational fields of planets on a flexible surface.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

In this physics activity, learners attempt to lift a jar full of rice using only a spoon.

In this activity, learners can create five-layer density columns by employing one of three (or all) methods.

In this physics activity (page 8 of the PDF), learners will explore the property of density.

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

This fun and simple hands-on astronomy activity lets learners explore what happens when a star explodes.

Learners conduct two activities to investigate two properties of liquids: density and viscosity. In a clear container, learners stack 7 different liquids which will layer according to their density.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

In this activity, learners make their own heat waves in an aquarium.

In this activity, learners discover the difficulty of ocean exploration by human beings as they investigate water pressure.

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

In this activity, learners create a model of a hot air balloon using tissue paper and a hairdryer. Educators can use this activity to introduce learners to density and its role in why things float.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

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.

In this activity, learners use oil, water, food coloring and antacid tablets to create a bubbling lava lamp. Use this activity to introduce concepts related to density, hydrophobicity vs.

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.
