Twirling in the Breeze
Source Institutions
In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

Crank It Up
Source Institutions
In this engineering activity, learners explore simple machines and then build cardboard automata using cams.

Exploring a Complex Space-Filling Shape
Source Institutions
In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.

The Carbon Cycle and its Role in Climate Change: Activity 3
Source Institutions
In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

Cup Speaker
Source Institutions
Make your own speaker with a magnet, wire, and paper cup! If you have a radio with a headphone plug and an old pair of headphones, this is a great tinkering activity.

Light Quest
Source Institutions
Learners test their "light-smarts" by playing a game called "Light Quest!" The game board represents an atom and each player represents an electron that has been bumped into the atom's outer unstable

Straw Oboe: Two lips make sound
Source Institutions
Oboes's unique sound originates from the two small reeds a musician blows into. Make your own double reed instrument out of straw!

Engineered Sports
Source Institutions
In this activity, learners explore the concept of how aerospace engineering has impacted sports, specifically exploring the design of golf balls.

Scaling an Atom
Source Institutions
In this activity, learners make a scale model of an atom to see how big or how small an atom is compared to its nucleus. Learners will realize that most of matter is just empty space!

Design Your Own Rube Goldberg Machine
Source Institutions
Engineer and cartoonist Rube Goldberg is famous for his crazy machines that accomplish everyday tasks in overly complicated ways.

Shell Shifts
Source Institutions
Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.

Soaring Satellites
Source Institutions
Working in small teams, learners try to build a satellite that can float for at least five seconds in the marked area of a vertical wind tube.

Kinematic Fanatic
Source Institutions
In this activity, learners are challenged to design and build a system of gears and kinematics to create a hand-stamping machine.

Gel Electrophoresis
Source Institutions
In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

Set It Straight
Source Institutions
In this activity, learners build a simple tabletop seesaw to test how different variables (the position of the fulcrum, distance, weight) affect its balance under increasing weight loads.

Get It Write
Source Institutions
In this activity, learners explore how pens have been engineered and re-engineered over time. Learners work as a team to develop a working pen out of everyday items.

Playing with Parachutes
Source Institutions
In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

Why are Compact Fluorescent Bulbs More Efficient?
Source Institutions
In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.

Does Sunscreen Protect My DNA?
Source Institutions
In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

Solar Powered Cooking
Source Institutions
In this activity, learners make a solar oven. Learners witness the awesome power of the sun to make a yummy treat--a chocolate chip cookie!
