Pendulum Time
Source Institutions
In this activity, learners explore how the pendulum has been a reliable way to keep time for centuries.
Chair Lift Challenge
Source Institutions
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.
Tall Tower Challenge
Source Institutions
In this activity, learners explore the design of tall structures such as skyscrapers and telecommunication towers.
Build a Band
Source Institutions
In this design challenge activity, learners build a four-stringed instrument that can play a tune.
Pop! Rocket Launcher
Source Institutions
In this activity, learners construct a simple air pressure launcher for paper rockets.
Pollution Patrol
Source Institutions
In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.
Smooth Operator
Source Institutions
In this activity, learners explore surgical instrument design. Teams of learners construct surgical instruments from everyday materials.
Filtration Investigation
Source Institutions
In this activity, learners explore how engineering has developed various means to remove impurities from water.
Rocket Wind Tunnel
Source Institutions
In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.
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.
Design a Park
Source Institutions
In this activity, learners are invited to imagine the park of their dreams!
Working with Watermills
Source Institutions
In this activity, learners explore how watermills have helped harness energy from water through the ages.
How the Rubber Meets the Road
Source Institutions
In this activity, learners explore how engineers design tire treads to increase safety and reliability.
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.
Blimp Jet Challenge
Source Institutions
In this design challenge activity, learners add a jet-propulsion system (i.e. a balloon) to a blimp so it flies straight and far under its own power.
Headphone Helper
Source Institutions
In this design challenge activity, learners add headphones to a previously built instrument (see "Build a Band" activity) to make it easier to hear.
Making Mosaics
Source Institutions
In this archaeology meets art activity, learners make a mosaic and consider the ways in which art communicates.
Popsicle Bridge
Source Institutions
In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit
Low-Tech Water Filter for High-Impact Clean
Source Institutions
In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.
Levers at Play
Source Institutions
In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).
