Make sure your house is warm in the winter. Pupils analyze graphs of heating costs for two similar houses and make hypotheses for why the costs differ. They then build models of houses with appropriate insulation to reduce heating costs.

Every child's dream: stuffing as much candy into a bag as possible. Doing this, though, requires a nice sturdy bag. Scholars design the sturdiest bag they can and test the limits of those bag using a sweet treat!

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.

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.

Discover the power of wind energy. Learners design, build, and test wind blades in a hands-on experiment. They analyze the results to determine if they can make any improvements before gathering as a class to discuss their designs.

Students examine the concepts of computer and mechanical engineering. They dissemble a computer mouse and create a new design for the mouse. They also design new enhancements for the mouse over time.

Nano-nano! Nanotechnology can seem like it's from another planet! After learning about this tiny technology, collaborative groups experiment with how smaller particles affect chemical reactions. They do this by immersing a whole and a...

How many noodles long is your classroom? Find out when engineers of all ages explore measurement through the use of pool noodles. With the noodles pre-cut to certain metric lengths, the activities could be used to introduce the metric...

Future engineers test different alloys to determine the specific strength of each one. Based on the results, they make a recommendation to NASA on which alloy to use on engines for spacecraft.

How can you teach a person about technology and engineering if he has never been exposed to the tools and devices used to create and construct? Learners with visual impairments examine a number of common tools, such as hammers, wrenches,...

How do engineers turn something that is readily available, like wind, into energy? Scholars create a prototype of a wind turbine and attach it to a motor. They test out their prototypes and decide on their effectiveness. They also...

Sail to the ground with a parachute activity! Kids construct parachutes out of household items and a toy figure, after brainstorming the best way to reduce drag. Once they test their parachutes, they can adjust their projects to...

Launch pupil interest in rockets. Scholars build rockets out of straws and balloons to learn about Newton's Third Law of Motion. Their task is to hit a target five feet away. It's not as easy as it seems!

Here's a lesson that is simply a-MAZE-ing! Introduce science scholars to pipeline systems through a hands-on project. Partnered pupils participate in the design, construct, and test a PVC pipeline maze. Reusable materials and clear...

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...

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...

Paper is a lot stronger than you think. Scholars create newspaper structures that can hold the weight of several books. For the purpose of this activity, the designs must be eight inches tall to be considered complete.

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...

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.

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.

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...

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...

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!

Whatever floats your boat—with some additional weight. The first activity in a five-part series challenges pupils to design a boat to hold pennies. Using the design process, learners design, build, and test their boats, making sure they...
