If a sailboat is stranded because there is no wind, is it possible to set up a fan on deck and blow wind into the sail to make the boat move?

Groups of learners are provided with a generic car base and an egg. Their mission: design a device/enclosure to protect the egg on or in the car as it rolls down a ramp with increasing slopes.

In this activity, learners use a laser pointer and two small rotating mirrors to create a variety of fascinating patterns, which can be easily and dramatically projected on a wall or screen.

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.

This activity (on page 2 of the PDF under SciGirls Activity: Hovercraft) is a full inquiry investigation into hovercraft engineering and design optimization.

In this activity, learners explore how nanosized structures can create brilliant color.

This activity (page 2 of the PDF under SciGirls Activity: Microgravity) is a full inquiry investigation into how ordinary things behave in microgravity, similar to what astronauts experience.

In this activity, learners build a recording timer made from simple materials (e.g., small dc motor, sharpie pen, craft sticks, adding machine paper tape, etc.).

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 activity, learners design, build and test wind turbines. Learners go through the design process and use the scientific method to test important blade variables.

This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

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 activity, learners explore how boats are engineered to achieve speed.

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

In this activity (posted on April 18, 2011), learners follow the steps to construct a zoetrope, a device that produces an illusion of action from a rapid succession of static pictures, using a 16" bik

In this design-based lesson, learners study flood dynamics as they modify a riverbed with blockages or levees to simulate real-world scenarios.

This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.
