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

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

This activity (on page 2 of the PDF under GEMS Activity) is a full inquiry investigation into technology design and testing.

In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from

In this puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.

In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.

In this activity, learners create a battery from fruit. This activity helps learners explore electricity, electrochemistry, and series circuits as well as the process of scientific inquiry.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.

In this design challenge activity, learners invent an emergency shelter that can fit a person and is sturdy and quick to build.

In this activity, learners will create their own percussion instrument with recycled materials. Learners will explore design, fabrication, cause and effect and sound through this activity.

In this activity, learners use a fictitious map of "Tourist Town" and counters to problem solve how to place ice-cream vans on street intersections so that every other intersection is connected to one

This activity aims to stimulate discussion on the question of whether computers can exhibit “intelligence,” or are ever likely to do so in the future.

In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.

This activity (on page 3 of the PDF under GPS: Sailboat Design Activity) is a full inquiry investigation into design optimization.

This activity (on page 3 of the PDF under GPS: Roller Coaster Design Activity) is a full inquiry investigation into g-force and acceleration.

In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

In this activity, learners examine nanoscale structures of common things.

This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.

This is a quick activity (on page 2 of the PDF under Hockey Sticks Activity) about how the arrangement of carbon atoms determines carbon's different properties.
