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

In this activity (7th activity on the page), learners use their sense of hearing to find a "sound match." Learners shake containers filled with items like dry seeds, sand, beans, etc.

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 will create paint out of natural materials. Explore your natural world (or your fridge) and find berries, leaves, or flowers to find a great base for your paint.

In this fun hands-on activity, learners whip up a batch of cyber-dough (play dough) using math for measurements.

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

In this activity on page 3 of the PDF, learners create a collage by using vinegar to transfer color pictures from a newspaper onto a piece of white paper.

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

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.

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").

In this activity, learners will estimate the sizes of balls to learn how to estimate the size of hail. Learners will compare their estimates to the estimates of their peers and the real measurements.

In this math activity, learners create their own units of measurement by making noodle rulers. Learners practice estimating and measuring objects using the noodle rulers .

In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.

In this activity, learners build a machine made of craft sticks to multiply the levering motion of their hands and create a device that bends and extends.
