Discover the wind's direction using bubbles, a map and a keen eye. Learners blow bubbles and note their general direction on a map, taking readings from different points around a building.

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 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").

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

In this activity, learners start their own field journal to better understand the wildlife in their area.

In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.

In this activity, learners will test the strength of different brands of paper towels.

On an airplane trip, learners have an opportunity to investigate the properties of air pressure at different altitudes.

This activity introduces learners to Native Americans as people who depended upon nature in the past and continue to emphasize the importance of nature in the present.

In this activity, learners build small animated toys that move.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

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.

In this activity, learners create their own obstacle course based on Bernoulli's Principle and try to get a floating ball from the start of their course to the finish line.

In this activity, learners will take a step back and learn the history of the land they live on, and the people who used to live on it.

This activity is a sensory experience that recreates the sounds of a pond at night.

In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.

In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.

In this activity, learners design a bungee jump for an egg using nylon stockings.
