Storm Water Runoff Pollution
Source Institutions
This activity (located on page 8 of the PDF) introduces learners to the concept of Non-point Source Pollution--what happens when rain washes garbage and other pollutants into rivers and lakes.

Design a Submarine
Source Institutions
Learners act as engineers and design mini submarines that move in the water like real submarines.

Touch Down
Source Institutions
In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.
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.

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.

Using Different Models of Earth
Source Institutions
In this activity, learners explore how the shapes, sizes, and distances of land masses appear differently on two different models of Earth: an icosahedron and a flat map.

Trebuchet Toss
Source Institutions
In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

Paper Puzzle
Source Institutions
In this math activity, challenge learners to make two equal rows from eight different paper strips. Learners can explore the many ways they can solve this problem.

Magnetic Seesaw
Source Institutions
In this activity, learners build a seesaw powered by magnets.

Critical Load
Source Institutions
In this activity, learners explore the concepts of structural engineering and how to measure the critical load, or the maximum weight a structure can bear.

Hanford at the Half-Life Radiation Calculator
Source Institutions
This quiz lets you estimate your annual radiation exposure.

Handheld Water Bottle Rocket & Launcher
Source Institutions
In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

Using a Sundial
Source Institutions
In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

Airfoils
Source Institutions
In this experiment, learners discover how an airfoil creates lift. Learners use simple materials to build an airfoil and test it at different angles to investigate Bernoulli's principle.

Weather Vane and Anemometer
Source Institutions
In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

Spring Scale Engineering
Source Institutions
In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.

Water Tower Challenge
Source Institutions
In this activity, learners explore how engineers work to solve the challenges of a society, such as delivering safe drinking water.

Life Vest Challenge
Source Institutions
In this activity, learners explore the engineering behind life vests or personal flotation devices and the challenges met by these devices.

Cup Draw (Low Tech)
Source Institutions
In this activity, learners construct drawing machines using a cup, some markers, and a battery pack. The markers act as "legs" for the machine, making a drawing that records as it moves.
