Learners explore water's property of cohesion through two investigations.

Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this activity, learners investigate how different materials repel or absorb water. Learners use spray bottles to explore how everyday items like sponges, cardboard, feathers, etc.

In this activity (on page 2 of the PDF), the learner places a golf ball between salt water and colored fresh water. The golf ball is not as dense as the saltwater.

In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.

In this activity, kids make and play with Ooze before testing the material in an egg drop!

In this activity, learners investigate and compare the rate of drying in different conditions.

In this experiment, learners separate different types of molecules in marker inks (using a technique called "thin layer chromatography").

Learners will compare the growth rate and appearance of crystals forming on small rocks to those growing on miscellaneous objects. Learners will also investigate how temperature (warm vs.

In this activity, learners build models of atoms and molecules, then consider their role in different phases of matter, density, and mixtures and solutions.

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

In this chemistry activity (page 1 of PDF SciGirls Activity: Milk Carton Boat), learners will create a blob of stretchable funny putty out of a water, borax, and glue mixture.

In this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises.

In this activity, learners investigate diffusion by creating underwater "fireworks" using food coloring, oil and water.

In this chemistry activity, learners are asked to form a hypothesis about the behavior of milk as household detergents act upon it.

In this math lesson, learners analyze the density of liquids in order to explore linear functions.

In this physics activity, learners will explore the concept of buoyancy, especially as it relates to density.

In this activity, learners explore how changes in fluid pressure affect the buoyancy of a Cartesian diver inside a plastic soda bottle.

Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.
