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.

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.

Shake up your lessons on earthquakes. A simple seismograph lets scholars record "earthquakes" in the classroom. These earthquakes occur when classmates drop balls from different heights. Young scientists measure these with seismographs...

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.

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.

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.

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.

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.

Art and science sometimes go hand in hand. A set of four activities for learners in grades 3-5 teaches engineering concepts as part of art projects. Class members build homemade robots, elastic puppets, musical instruments, and...

In 1993, five biomedical engineers in Edinburgh, Scotland, created the first functional bionic arm. In the activity, learners explore the world of bioengineering through discussion and hands-on exploration. In groups, participants...

What is the best way to test water quality? Using plastic bottles, scholars create monitoring sensors to test water quality. Creating three different sensors allows individuals to measure water quality at different water levels.

Help your class understand the importance of exploration using robots. with a resource that provides a short history of robotics as a lead into looking at Martian robotic exploration missions. The activity specifically looks at the...

You've probably heard of solar-powered cars, but what about wind-powered cars? Scholars build cars that can travel at least six feet. They can only use their breath to move the car—so, obviously, a sail might be a good feature for the...

Herbivores and carnivores just don't get along. Using a box of animal crackers, classes collect data about the injury status of herbivores and carnivores in the box. They complete the process of chi-square testing on the data from...

Could you reinvent the light bulb? Scholars tap into their inner Thomas Edisons to build a light bulb prototype out of a jar and some wires. They see how long the filament wire glows in the jar (batteries not included) to measure their...

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.

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.

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.

Stability is key when building a bridge. Scholars explore the forces acting upon bridges through an analysis of Newton's Laws and Hooke's Law. The activity asks individuals to apply their learning by building a bridge of their own.

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.

It's time! The fourth lesson in a five-part series has teams of scholars build a circuit for an alarm. A switch lets them turn the alarm on and off and allows them to hide the alarm—just as long as they don't hide it in the classroom!

Imagine seventh graders developing a school wide plan to promote respect in their school. That's the vision behind the second lesson plan in the R-E-S-P-E-C-T series. In preparation for designing a school-wide media campaign, class...

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!

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!
