Students design and create their own air-powered rockets, in this hands-on activity.

Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.

In this food science activity, learners explore digestion and proteins by observing the action of meat tenderizer on luncheon meat.

In this activity, learners of all ages can enjoy experimenting with ice. Try this experiment at the kitchen table or in the great outdoors to encourage budding scientists to experiment with ice.

In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.

In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

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

In this outdoor activity and bingo-like game, learners explore why and how seeds spread far from the plants that produce them.

In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

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 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, learners explore what happens when polarized white light passes through a sugar solution.

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").

Learners compare the weight of equal volumes of wax, water, and clay. Learners discover that since the wax weighs less than an equal volume of water, it is less dense than water and will float.

Learners create hard water by mixing Epsom salt and water. Then they compare what happens when soap solution is mixed with hard water and regular water.

Learners construct and use a "real" 3D coordinate system out of balsa wood and foam core. They will then be able to locate coordinates in space.

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