Four Corners
It's imperative to be as precise as possible. Future engineers learn about precision by building a cardboard machine. The base, corners, handles, and paddles must all be assembled with precision or the machine won't work.

Pop Fly
A lever comes in handy when scholars build a launcher for a ping-pong ball. They test the launcher and redesign it to send the ball higher or to accommodate a tennis ball. This is the third lesson in a five-part unit.
PBS
Kinetic Sculpture
Build a sculpture that moves on its own; no power source required! The second installment of a five-part series has individuals create a sculpture that moves with the wind. It can't topple over though, so some type of support is necessary.

Rubber Band Car
Class, start your engines. Future engineers design a car with old CDs as wheels. The power source? Some rubber bands will do the trick! This is the first installment of a five-part series.

Build a Bridge
Cost overruns are unacceptable—in the real world and in an engaging activity. Groups of pupils get together to build a bridge out of straws, paper cups, and tape. They keep track of costs ($1,000 for each material) and must stay within a...

Slime!!
Who's going to get slimed? Your entire class! Scholars create slime using Borax, water, and white glue. Some food coloring can give the slime a bit of color.

Textbook Support Challenge
Textbooks are heavier than a sheet of paper, so how can paper hold up a textbook? Young engineers create a structure out of paper that can support a textbook. To add another wrinkle, they must stay within budget and time constraints.

Product Dissection
Sometimes, taking things apart is more fun than putting things together. Groups of learners participate in a reverse engineering activity. They dissect a device of their choosing to see how it works—great hands-on learning from the...

Wind Farm
A wind turbine is essentially just a giant pinwheel, right? Individuals first create pinwheels from paper, pins, and pencils. In groups, they model a wind farm along a coast and then test out their designs using an electric fan.

Paper Tower
Read all about it! Challenge your class to build taller and stronger. Newspapers provide the means to build towers in a simple activity. Scholars try to build as tall a tower as possible with just two sheets of newspaper.

Pilot a Balloon
Balloons will go where you want them to. Young pilots first add paper clips to a balloon to make it neutrally buoyant. They then use cardboard to steer the balloon in different directions, taking air pressure into account.

Harmless Holder
Here's a lesson that's not for the birds! Scholars design and build packaging for soda cans that is environmentally friendly. These packages must be durable, easy to carry, and have no environmental impact.
DiscoverE
Siphon Pump
Defy the laws of gravity. A simple activity has learners create a siphon pump for water. The challenge is to get water to flow upwards through a tube.
DiscoverE
Tunnel Meetup
Meet me in the tunnels. Scholars choose a tunnel entrance and mark it on their side of the cardboard. They describe the location to their partners and see if they can guess each other's locations. Punching a hole through the cardboard...

A Clever Way to Water
Your plants will survive without you. Scholars create a device that can water plants using a coiled string. Along the way, they learn about adhesion and cohesion of water. The challenge is to keep the plants alive for at least a week.
DiscoverE
Shaky Ground
You're on solid ground if you decide to use the resource. A simple activity has young engineers investigate the problem of liquefaction. A battery placed on dry sand will stay standing—but not if scholars add water to the cup.

Sun-Warmed Treats
Treat your class to a fun activity, complete with treats. Groups create a solar oven from a pizza box. They then use it to heat up some food ... that's what an oven is for, after all!
DiscoverE
Clean It Up
Water, water, everywhere, but not a drop to drink—until we clean it, of course! Scholars design a filtration device that removes pollutants from water. The goal is to have the water come out as clean as possible from the device. How...

Kicking Machine
Don't kick the resource to the curb; you'll definitely regret it. Future engineers devise a kicking machine that launches a ping-pong ball toward a target. They can use a pendulum, a rubber band, or both, depending on whether they want...

Kinetic Sculpture
Let your creativity run wild. Scholars build a sculpture out of basic materials. These sculptures must be able to move in the wind (from an electric fan). However, they must also withstand the wind enough to not fall over—it's quite the...

Hold Your Water
Let's hope there are no leaks. Pupils work together in groups to build a device that will keep as much water as possible in a cup. After being dropped from a height of seven feet! Time to haul out the ladder.

An Egg-Citing Ride
Wheeeee! Young thrill seekers build a bungee jump—not for themselves, though, but for an egg. The egg must fall from a height of five feet and rebound within two inches of the ground or floor.
DiscoverE
Rocket-Powered Ski Lift
If a ski lift had rockets, imagine how fast it would be! Scholars let their imaginations take flight as they build models for such a ski lift. Rather than using a rocket, though, they'll use a much safer balloon as the power source.

Dome Home
Homes come in many different shapes and sizes. Building a model of a geodesic dome is the ultimate goal for the activity. Cutting and folding is the way to go here.
