Wonderful Weather
Source Institutions
In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

Draggin' Boats
Source Institutions
Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

Two Button Buzzer Circuit
Source Institutions
In this activity, learners explore an everyday situation, where either of two or more buttons can ring a buzzer.

Telescoping Periscope
Source Institutions
In this activity, learners explore the many uses of periscopes and how this simple device was designed and is used in many applications.

Mirror, Mirror
Source Institutions
In this activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.

Cast Your Vote
Source Institutions
In this activity, learners explore how voting systems have changed with engineering advances over time. Learners work in teams to design their own voting system using easy to find materials.

Adaptive Device Design
Source Institutions
In this activity, learners explore the concept of how engineering has made possible the development of--and ongoing improvements to--adaptive devices that serve to help individuals with a wide range o

Vectoring: Steering a Plane
Source Institutions
In this two part activity, learners work in pairs or individually to discover how vectoring the thrust from a jet engine affects movement of an airplane.

Pipeline Challenge
Source Institutions
In this activity, learners explore how engineers develop pipeline systems to transport oil, water, gas, and other materials over very long distances.

Rubber Band Racers
Source Institutions
In this activity, learners explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.

How Do We Convert Mechanical Energy into Electrical Energy?
Source Institutions
In this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.

Investigating the Uses of Backyard Bacteria
Source Institutions
The purpose of this lab is to recognize that the answers to some of society's industrial challenges may lie right in our own backyards.

Card Flip Magic: Error Detection & Correction
Source Institutions
This magic trick is based on how computers detect and correct data errors.

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.

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.

Pendulum Time
Source Institutions
In this activity, learners explore how the pendulum has been a reliable way to keep time for centuries.
