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.
DiscoverE
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...
DiscoverE
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...
DiscoverE
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...
DiscoverE
Friction in Action
There's no need to have friction among instructors regarding the resource. Pupils investigate how marbles and coins slide along different surfaces which gives them information to estimate coefficients of friction.
DiscoverE
Oranges and Batteries
Orange you glad you can make circuits using fruit? Young electricians learn about electric circuits and electricity. As part of the lesson, they build a circuit with an orange and then with a banana.
DiscoverE
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.
DiscoverE
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
Paper Recycling
Paper is made from paper, right? Future scientists take bits of paper and produce sheets of recycled paper. The only drawback? It has to dry overnight.
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.
DiscoverE
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.
DiscoverE
Electromagnetic Fishing Pole
Let's go fishing ... for paper clips! Individuals create a device that attracts paper clips. This device relies on an electromagnetism, where a flow of electricity in a loop of wire wrapped around a nail causes magnetism.
DiscoverE
Human Suspension Bridge
When is it okay to be suspended in school? When you're part of a human suspension bridge! Learners first model tension and compression in pairs. Once complete, they get together as a class to model a suspension bridge.
DiscoverE
Slinky® Science
Toys are great for learning about physics. Scholars use Slinky® toys to study Newton's laws of motion and types of energy. After a little play, they then model longitudinal and transverse waves with the Slinky® toys.
DiscoverE
First You See It, Then You Hear It
Light and sound go hand in hand. Pupils set up a system that will emit sound when a laser is directed at a photodiode. Various objects, such as a comb and talcum powder, allow for modulation of the laser beam. Individuals also...
DiscoverE
Build a Better Boomerang
This isn't the boomerang you're used to. Scholars first see how a commercial boomerang works. They then cut out a four-wing boomerang and test its flight to compare it to that of the commercial boomerang.
DiscoverE
The Power of Graphene
When you think electric circuits, your pencil probably isn't the thing that comes to mind. A simple experiment lets learners test whether the graphene in pencil lead is a conductor or an insulator. If the LED bulb lights up, a conductor...
DiscoverE
Human Arch
Sometimes, we all need somebody to lean on. Scholars create a human arch by leaning against each other. They consider different approaches to making the arch sturdier and stronger.
DiscoverE
Air Train
Train your pupils to be master engineers. Young learners design a train that travels along a fishing line. The train needs to safely carry pennies as passengers without falling out.
DiscoverE
Spaceship to Mars
Feel like a rocket scientist for the day. Using only paper and tape, scholars create a framework for a spaceship to Mars. Each sheet of paper costs $10 million and each piece of tape costs $100,000. Make sure you stay within budget!
DiscoverE
Building Begins with a Beam
A sturdy beam made of foam seems like an oxymoron. Scholars design a 48-inch beam that can hold a one-pound weight. The beam should be sturdy enough so it doesn't bend too much. If it does, the egg placed underneath the beam will break.
DiscoverE
Let Your Lights Glow
Put those old holiday lights to good use. Individuals use a section of ornamental lights to create electric circuits. If the lights glow, it's a success; otherwise, it's time to try again!
DiscoverE
Solar-Heated Water
Heat up some interest in solar energy. Young engineers create a water heater that runs on solar power (simulated by a lamp). Using thermometers, they determine the change in temperature before and after the water goes through the heater.
