Pop Rockets
Source Institutions
Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.
Making Metals Strong
Source Institutions
In this activity, learners demonstrate the effects of cold-working (strain-hardening) and annealing. Learners discover that these processes change the load that a wire can support.
Puppet Play
Source Institutions
In this activity, learners will make a marionette puppet and put on a show. Learners will explore color, design, fabrication and storytelling through this activity.
Make and Fly a Helicopter
Source Institutions
Learners follow the template to build and fly a paper helicopter.
Sky Glider Challenge
Source Institutions
In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.
Keep-a-Cube
Source Institutions
In this activity, challenge learners to keep an ice cube from completely melting in 30 minutes. Learners engineer a box or wrap to prevent an ice cube from melting.
Mechanical Grabber
Source Institutions
In this engineering activity, challenge learners to make a "grabber" that can pick up trash. Learners use simple materials to create pinchers that can grab small items.
Garden Poles
Source Institutions
In this activity, learners build large-scale structures and cantilevers in a series of "building out" challenges with garden poles and tape.
Patterns in Pixels
Source Institutions
This activity (page 2) draws upon a familiar, computer-based concept related to visual resolution: pixilation.
Build a Borneo Glider
Source Institutions
In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So
Robot Basketball
Source Institutions
In this activity, learners explore accuracy and precision.
Nano Latch-n-Catch
Source Institutions
In this activity, learners design a therapeutic agent to image and/or cure various diseases in the respiratory system.
Topographic Investigation: Map an Underwater Surface
Source Institutions
In this activity, learners create a map of a hidden surface using a "sounding stick" -- a technique similar to how underwater maps were once made.
Dowels and Rubber Bands I
Source Institutions
If you have 3-foot dowels and rubber bands, you can can started on this fun and open design challenge. You can make structures big and small: make it so you can fit your parent into it!
Pendulum Time
Source Institutions
In this activity, learners explore how the pendulum has been a reliable way to keep time for centuries.
Jet Propulsion
Source Institutions
In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.
Arduino Blink Challenge
Source Institutions
In this activity, learners explore computer programming and the impact of computers on society. Learners build and test a program to turn a light on and off using an Arduino board.
Swing That Pendulum
Source Institutions
In this full inquiry activity (located on page 3 of the PDF under GPS: Kinetic Sculpture Challenge Activity), groups of learners will make predictions about which feature of a pendulum (mass, length,
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.
Hang Time
Source Institutions
Learn how to make and fly a paper helicopter! This simple activity includes a template (for the copter "blades") and instructions for folding, flying, and testing designs.
