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 activity, learners discuss the different salinities of oceans, rivers and estuaries.

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

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 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.

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 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.

In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.

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, learners are introduced to challenges of maintaining temperatures while living in space.

In this hands-on activity, learners will construct a scuba diver that can float in order to explore how sea creatures stay neutrally buoyant in the ocean and to see what kinds of forces might be influ

Learners observe a tank of water containing cans of diet and regular sodas. The diet sodas float and the regular sodas sink. All the cans contain the same amount of liquid and the same amount of air.
