Good Vibrations
Visualize vibrations within the classroom. Pupils see the connection between sound and waves. The learners use a tuning fork in two different ways to demonstrate the waves associated with sound. Scholars see how the sound waves from a...

Utah Open Textbook: 3rd Grade Science
How do we interact with Earth? Scholars learn about the sun, Earth, moon, forces, gravity, and heat sources by reading a text and performing hands-on demonstrations. They also differentiate between living and non-living things using...

Build a Roller Coaster
Let the good times roll as young thrill seekers build a roller coaster on school grounds. Future engineers design and build a roller coaster from flexible tubing. The roller coaster is for a marble, so there will be plenty of room to let...

Build a Straw Bridge
Build teamwork skills while building a bridge. Scholars work together in groups to create a bridge out of 20 straws and tape. There is a minimum span length of 25 centimeters, but otherwise, let creativity run wild.
DiscoverE
Critical Load
Help your class master the important concept of critical load. Pupils work together to build a structure using 12 playing cards. They test the critical load of the structure using pennies or paper clips.

Let's Make an Elastic Puppet
Create bending joints—but don't break! The activity shows how to make a puppet using straws and fishing line. Pupils create cuts to make joints that rely on the elasticity of the straw to bend and return to their original shapes.
DiscoverE
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.
DiscoverE
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.
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...

Oranges and Batteries
Orange you glad you can make circuits using fruit? Young electricians learn about electric circuits and electricity. As part of the activity, they build a circuit with an orange and then with a banana.

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.

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.

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.

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
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
Seismic Shake-Up!
Shake your earthquake-resistant building prototype! Groups create structures using coffee stirrers and clay that can withstand seismic waves. They then test their structures against their own earthquakes.
DiscoverE
Marble Run
It's time to slow your roll! Can your class create a track that allows a marble to roll as slowly as possible? Teams of science scholars collaborate to design, build, and test their tubes while learning about gravity and friction.
DiscoverE
Build a Spinning Top
There's no spin needed to describe the usefulness of a dizzying resource! Using paper plates, DVDs, wooden skewers, and pencils, learners work in teams to create spinning tops. The longest-spinning top wins.
DiscoverE
Conveyor Belt
Convey your interest in conveyor belts. By considering different size tubes, groups create a conveyor belt that can transport boxes of candy at least four feet. Also, the conveyor belt must make a 90-degree turn—quite a difficult task!

Rocket Challenge
You might just be responsible for launching a future career in rocket science. Pupils use Alka-Seltzer® tablets as the power source for a film-canister rocket. These rockets must able to carry a clay payload and hit a target on a wall.
