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

Cooling Off
Source Institutions
In this activity, learners are introduced to challenges of maintaining temperatures while living in space.

Human Interface Design: The Chocolate Factory
Source Institutions
In this activity about human interface design issues, learners help the Oompa-Loompas of a great chocolate factory solve different problems.
Build a Super Structure
Source Institutions
In this activity, learners use things from the kitchen as building materials to explore how shapes contribute to the strength of different structures.

Fun with Speedboats
Source Institutions
In this activity, learners explore how boats are engineered to achieve speed.

How the Rubber Meets the Road
Source Institutions
In this activity, learners explore how engineers design tire treads to increase safety and reliability.

Paper Table
Source Institutions
In this design challenge activity, learners use tubes of newspaper to make a table that’s at least eight inches tall and strong enough to hold a heavy book!

Copy Cats
Source Institutions
In this math activity, learners use what they know about shapes to copy a friend's hidden picture. Learners create a design out of pattern blocks and then hide their picture behind a screen.
Needlework Designs
Source Institutions
In this math activity, learners create symmetrical designs for paper models of special blouses known as huipiles.

Simple Pop-Up Mechanisms
Source Institutions
In this activity, learners construct three quick and simple mechanisms to start building a pop-up book. Learners fold, cut, and glue paper to make a bird beak, parallelogram, and V-fold.

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

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

As the Rotor Turns: Wind Power and You
Source Institutions
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

Cylindrical Wing
Source Institutions
In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

Balsa Towers
Source Institutions
Learners work in groups to design and build a tower out of balsa wood. As a motivator, they can compete to build a tower with the highest strength-to-weight ratio.

Ramps 2: Ramp Builder
Source Institutions
In this inquiry-based learning activity, learners design, build, and test their own ramps. They are introduced to a variety of materials and explore putting them together.

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

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

Fun with Shapes
Source Institutions
In this activity, early learners combine pre-cut recognizable shapes and their own abstract ideas to make representational pictures (e.g. houses, trees, shoes).

Lift Off!
Source Institutions
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.
