Stack 'Em Up
Source Institutions
In this simple and fun activity, learners build a tower of cups to explore distribution of weight. Learners make predictions about their towers and test their designs.

Sticky Structures
Source Institutions
In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.

Out of Sight: Remote Vehicle Activity
Source Institutions
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.

Oil Spill Solutions
Source Institutions
In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

Filtration Investigation
Source Institutions
In this activity, learners explore how engineering has developed various means to remove impurities from water.

Three Little Pigs
Source Institutions
In this activity, leaners explore building techniques by recreating the story of The Three Little Pigs.

Trophy Triathlon
Source Institutions
In this activity, learners are challenged to design and construct a trophy for prize-winning sports equipment.

Ewok Escape
Source Institutions
The goal of this Star Wars activity is to design and build a balancing device to help an Ewok escape the Imperial Forces by sliding down a tightrope to safety.

Vocal Visualizer
Source Institutions
With a bit of PVC, a laser, a can/cup, and a small mirror, you can make a device that visualizes you voice or any sound transmitted into the cup/can.

Rocket Wind Tunnel
Source Institutions
In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

Wind Works!
Source Institutions
Learners will build and experiment with their own windmills made from simple household materials.

A Simple Escapement Mechanism
Source Institutions
In this activity, learners build a simple mechanism that regulates the "escape" of energy released by a falling weight by portioning it into discrete amounts.

The Squeeze is On
Source Institutions
Each group of learners uses everyday materials, such as paper, toothpicks, and tape to design and construct a structure intended to support the weight of a cinder block for 30 seconds.

Cooling Off
Source Institutions
In this activity, learners are introduced to challenges of maintaining temperatures while living in space.
No bones about it!
Source Institutions
This is an activity (located on page 3 of the PDF) about the mixture of materials in bone and how they affect its strength.
Building a Community From the Ground Up
Source Institutions
In this activity, a group of learners work collaboratively to design and construct a paper model showing the evolution of an environment through multiple stages, from prehistory through the modern cit

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.
Hazardous Chemicals in Your Neighborhood
Source Institutions
In this environmental science lesson, learners will examine hazardous chemicals and their effects on human health and the environment.

Leaning Tower of Pasta
Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

Confetti Launcher
Source Institutions
Hooray! In this design challenge activity, learners invent a device that launches a spoonful of confetti into the air. Learners are encouraged to create the biggest cloud of confetti possible.
