In this activity, learners discover if carbon dioxide has an effect on temperature.

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

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

In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

In this activity about molecular diffusion (located on page 2 of the PDF under Nanosilver Activity), learners will make predictions and move molecules of iodine through a seemingly solid plastic sandw

In this quick and easy activity and/or demonstration, learners illustrate the effect of the weight of air over our heads.

In this activity, learners construct hail-proof houses using recycled materials to discuss storm readiness and safety.

In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this activity, learners explore how engineers design tire treads to increase safety and reliability.

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

In this activity and/or demonstration, learners illustrate visually and physically that air has weight. Learners balance two equally-inflated balloons hanging from string on a yard stick.

In this quick activity, learners observe how wind creates ocean currents.

In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.

In this Spanish-language chemistry activity, learners use simple materials to explore how fire extinguishers work to put out fires.

In this activity, learners explore the engineering behind life vests or personal flotation devices and the challenges met by these devices.
