In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

In this activity, learners explore how engineers work to solve the challenges of a society, such as delivering safe drinking water.

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.

Water sticks to all kinds of things in nature — flowers, leaves, spider webs - and doesn't stick to others, such as a duck's back.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

In this activity, learners build a water squirter using a PVC pipe, dowel, and foam. This activity is great for the summer time and introduces learners to forces and water pressure.

In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

In this demonstration, learners observe as two cola bottles and a dollar bill are arranged in a specific order: one bottle, upside down and filled with water, is placed on top of another bottle, with

In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

In this physics activity, learners conduct two experiments to explore free-falling.

In this activity, learners will use simple materials to explore centripetal force and variables by swinging a cup of water without having the water spill out.

In this activity, learners use sieves with different-sized holes to sort balls by size.

In this activity, learners investigate convection by using food coloring and water of different temperatures.

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

In this physics activity (page 5 of the PDF), learners will witness the effects of free fall by observing falling water, and will gain a better understanding of the concept of weightlessness.

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.

Perform this classic inertia demonstration to illustrate the transfer of potential energy to kinetic energy.

In this activity, learners use simple items to construct a device for indicating air pressure changes.
