In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

In this design challenge, learners will engineer a structure and see if it can survive an earthquake they create.

In this activity, learners explore the function and engineering of dams and how dams have many uses and solve many problems in the world.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

Using simple, inexpensive items, learners build and test submarine models.

Learners construct one or more of the following kinds of sundials: a shadow plot, a horizontal sundial, and a diptych sundial.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this activity, learners explore rocketry and the principals of space flight.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

In this activity, learners will engineer three different parachutes to test how well each one works.

Learners recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and learners perform several velocity calculations.

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

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.

Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.

In this activity, learners investigate passive solar building design with a focus solely on heating.
