This activity (located on page 3 of the PDF under GPS: Alligator Habitat Activity) is a full inquiry investigation into organisms and the health of their ecosystems.

This is an activity about turbidity, or the amount of sediment suspended in water.

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

In this activity about states of matter, learners get to witness firsthand the awesome power of air pressure. They watch as an ordinary soda can is crushed by invisible forces.

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 explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.

In this activity, learners add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules.

April showers bring May flowers, but what do coastal storms bring?

In this math lesson, learners predict, interpret, and sketch graphs of functions related to the shapes of bottles. A measure of water is poured into a container.

This is an activity about our sense of smell and how it compares to sharks' super noses. Learners will create varying solutions of water and perfume.

Learners will see that changing the shape of an object, like a clay ball, that is more dense than water, can affect whether the object will sink or float.

In this activity (on pages 4-5), learners make fake snow by adding water to the super-absorbant chemical from diapers, sodium polyacrylate.

In this activity (12th on the page), learners investigate their ability to discriminate (see) different colors.

In this activity, learners explore temperature changes from chemical reactions by mixing urea with water in one flask and mixing calcium chloride with water in another flask.

In this activity, learners make film canister rocket ships. A fin pattern is glued onto the outside of the canister, and fuel (water and half an antacid tablet) is mixed inside the canister.

Learners see that a can of regular cola sinks while a can of diet cola floats. As a demonstration, bubble wrap is taped to the can of regular cola to make it float.

In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

Learners add drops of four liquids (water, alcohol, salt water, and detergent solution) to different surfaces and observe the liquids' behavior.

Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.
