In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.

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 water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

In this activity, learners build water-propelled engines from soft drink cans.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

No glue is needed for learners of any age to become marshmallow architects or engineers.

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 will use chemistry to create a night sky watercolor painting. They will experiment to learn the effects of mixing crayon, salt, and lemon juice with water color paints.

In this physics activity, learners experiment with the attractive and repulsive power of magnets.

Learners observe and record what happens when they manipulate bottles containing a liquid (water or corn syrup) and one or more objects (screw, nail, paper clip).

In this activity (on pages 13-16 of the PDF) learners investigate three mystery samples to see which one contains life. The three samples are sand, sand and yeast, and sand and antacid.

In this Bob the Builder(TM)-themed activity, learners explore what it means to work together as a team.

In this Bob the Builder(TM)-themed activity, learners explore the 3Rs (Reduce, Reuse, Recycle) by rotating through several activity stations.

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

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