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.

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

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

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.

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

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

In this activity on page 12 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners examine how recyclable materials are separated by various properties at recycling centers.

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

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.

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

This activity was designed for blind learners, but all types of learners can utilize it to investigate volume, mass, and density.

In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

Learners create beautiful fluid motion. They explore fluid dynamics, surface tension, solubility, and buoyancy while mixing liquids together.

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

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

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 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.
