In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

In this activity, learners are challenged to build a bird feeder using recycled materials from home and are encouraged to problem solve during the extensions.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

In this activity, learners construct a home-made journal with simple, everyday materials.

In this activity, learners use simple, everyday materials to experiment with balls and ramps.

In this activity, learners use found natural materials to create a water haven for bees and other insects.

In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

In this outdoor activity, learners use pegs (like tent pegs) and string or elastic to simulate drill sites and roads in Northern Canada.

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

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

In this activity, learners make a small batch of biodiesel that will work in any diesel engine. Learners use an old juice bottle as a "reactor" vessel to chemically process vegetable oil into fuel.

In this activity, learners explore how engineers have improved roofing designs and materials in order to protect the contents of buildings.
