In this activity, learners explore the unique challenges in transportation engineering, such as devising a method for skiers or hikers to get to the top of a mountain.

In this math lesson, learners participate in several activities where they apply measurement skills.

In this activity, learners compare plant and animal life in different habitats including a sidewalk crack and lawn. Learners sort human-made materials and natural materials found in each habitat.

This activity shows how our experience of the Sun changes with time and location. The sun dagger at Chaco Canyon is thought by many to be a sort of ancient timekeeping device.

In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.

In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.

In this activity, learners explore the devices used over time to measure changes in temperature.

In this activity, learners will build a roller coaster for a marble to run on using everyday household materials such as paper towel or toilet paper rolls, cups, boxes, books, buckets, chairs, etc.

Learners build models of sinkholes to gain an intuitive knowledge of their physical aspects.

In this activity, learners explore chemical engineering and how the processes of chemical plating and electroplating have impacted many industries.

In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.

In this activity, learners calculate their water usage (in cups and galloons) during an average shower. Learners also chart and analyze water usage during showers in their households.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this 6-7 day investigation, learners begin with an introduction to seamounts that are present in the Gulf of Alaska.

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

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

In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.

In this activity, learners take on the role of a carbon atom and record which reservoirs in the carbon cycle they visit.

In this activity, learners explore surgical instrument design. Teams of learners construct surgical instruments from everyday materials.

In this robotics activity, learners drive a remote-controlled car through a course to learn the challenges faced while trying to operate a planetary rover.
