In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.

In this chemistry demonstration, learners will discover that phenolphthalein is a chemical that displays different colors depending on the acidity or basicity of the environment.

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

Learners conduct an experiment to determine the rate at which two materials, sand and water, heat up and cool down.

In this water activity, learners discover ways to move water across the water table.

In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

In this exciting and tasty chemistry activity which requires adult supervision, learners explore how chemistry affects a simple everyday activity like cooking.

In this activity, high voltage is applied across a pickle to emit a yellow glow. This activity should only be conducted by skilled adults and is best suited as a demonstration.

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

In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla

In this activity, learners discover the difficulty of ocean exploration by human beings as they investigate water pressure.

In this design challenge activity, learners invent a device that will make their friends and family ask, "What's buzzing?" Learners design an alarm with an on/off switch that is small enough to hide.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height.

In this activity about magnetism (page 15 of the PDF), learners will explore how opposite and similar magnetic poles affect a swinging (pendulum) magnet.

In this activity about transfer of energy, learners get to build their own catapult using nothing more than a plastic spoon and some tape.

In this hands-on activity, learners determine the types of chemical reactions achieved when combining different household products.

Learners classify a variety of objects by their characteristics. They then design an experiment to determine which objects float or sink in water and add this characteristic to their classification.

During this activity, learners will make different versions of "ooze" using varied proportions of detergent and glue.
