Exploring a Complex Space-Filling Shape
Source Institutions
In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.
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
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.
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.
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.
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!
Measuring Wind Speed
Source Institutions
In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.
Shake it up with Seismographs!
Source Institutions
In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.
Design a Lunar Rover!
Source Institutions
In this team design challenge (page 2-10 of PDF), learners design and build a model of a Lunar Transport Rover that will carry equipment and people on the surface of the Moon.
Get a Leg Up
Source Institutions
In this activity, learners experiment and collect data during a simulation of the fluid shifts experienced by astronauts' bodies in microgravity.
Diaper Dissection
Source Institutions
This is written as a display, but can easily be adapted to a hands-on activity. Learners discover how all the parts of a diaper work together to keep babies dry and comfortable.
Sail Away
Source Institutions
In this activity, learners explore watercraft engineering and sailing.
Design a Landing Pod!
Source Institutions
In this team design challenge (page 11-18 of PDF), learners design and build a Landing Pod for a model Lunar Rover (previously built in activity on page 1-10 of PDF).
Eye Spy
Source Institutions
This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.
Tired Weight
Source Institutions
Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.
Mini Zoetrope
Source Institutions
In this activity (posted on March 27, 2011), learners follow the steps to construct a mini zoetrope, a device that produces an illusion of action from a rapid succession of static pictures.
Designing a Wall
Source Institutions
In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.
Pico Cricket Compass
Source Institutions
Learners can program a compass to draw a circle by itself using a Pico Cricket, some Legos, and lots of tape! Pico Cricket is required.
