In this activity, learners explore how to protect their skin while applying pesticides to plants.

In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.

In this activity on page 4 of the PDF (Get Cooking With Chemistry), learners investigate ingredients that combine to produce gas bubbles.

In this activity, learners create a "Jam Jar Jet" based on Francois Reynst's discovery of a pulsejet engine, which uses one opening for both air intake and exhaust.

In this activity, learners experiment with different variables in making hollandaise sauce to achieve the correct texture and consistency.

In this activity, learners explore sublimation by conducting experiments with dry ice.

This activity uses Jell-O(R) to introduce learners to microfluidics, the flow of fluids through microscopic channels.

In this activity, dry ice and other items are used to construct a demonstration model of a comet that illustrates the comet nucleus, coma, and tails.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this activity, learners create a gelatinous slime using guar gum powder and borax. Educators can use this simple activity to introduce learners to colloids.

This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.

In this activity, learners use aluminum trays and wooden blocks to form stream tables to investigate river formations in two different landscape scenarios.

In this activity, learners perform an experiment to find out what determines a flower's color.

In this activity, learners discover the relationship between temperature and pressure in the lower atmospheres of Jupiter and Earth.

In this activity, learners explore how pneumatics and hydraulics could be used to produce movement in a robotic arm.

In this experiment using sprigs of Elodea, learners will observe a natural process that removes carbon dioxide (CO2) from Earth's atmosphere.

In this physics activity, learners will gain a better understanding of how friction, inertia, and mass affect objects.

Learners will build and experiment with their own windmills made from simple household materials.

In this three-part activity, learners explore how waves are formed and why some waves are bigger than others. First, learners observe waves of water in a pan generated by an electric fan.
