In this activity, learners discover how geologists use stratigraphy, the study of layered rock, to understand the sequence of geological events.

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

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

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

Can gelatin (like Jell-O ®) change the speed of light?

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

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

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

In this geology and engineering activity (page 7 of the PDF), learners build an earthquake simulator, then use it to test various building designs, exploring different materials, shapes, and design op

In this activity, learners explore Charles' Law in a syringe.

Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.

In this activity, learners work in teams build and launch rubberband-powered foam rockets.

In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.

In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.

In this activity, learners will use cereal to conduct an experiment and investigate how decreased bone density is related to increased risk of bone fracture.
