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.

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.

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.

Build a Better Roof
Source Institutions
In this activity, learners will engineer a roof using simple materials to protect a construction paper person from a rainstorm.

Pop! Rocket Launcher
Source Institutions
In this activity, learners construct a simple air pressure launcher for paper rockets.

Cranking Bird
Source Institutions
In this activity, learners build a mini crank machine to make a bird "fly." This engineering activity introduces learners to automata, rotational motion, cranks and cams.

Dispenser Designs
Source Institutions
In this activity, learners explore how engineers work in a team to solve problems.

Investigating Ice Worlds
Source Institutions
In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.

Temperature Tactics
Source Institutions
In this activity, learners explore the devices used over time to measure changes in temperature.

Launch Altitude Tracker
Source Institutions
In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

Using Ohm's Law to Build a Voltage Divider
Source Institutions
In this activity, learners apply Ohm’s Law to construct voltage divider circuits. Learners discover how to read resistor codes and calculate resistor values.

Thrill Ride
Source Institutions
In this activity, learners will build a roller coaster for a marble to run on using everyday household materials such as paper towel or toilet paper rolls, cups, boxes, books, buckets, chairs, etc.

Blow It Away
Source Institutions
In this activity, learners design wind-powered cars out of simple household materials. Students have fun designing and then racing their vehicles around the room.

A Question of Balance
Source Institutions
In this activity, learners explore how engineers use scales and measures when designing a manufacturing process to ensure that final products are uniform in weight or count.

Can You Copperplate?
Source Institutions
In this activity, learners explore chemical engineering and how the processes of chemical plating and electroplating have impacted many industries.
