Pack just enough to fit. Crews determine what personal items to take with them on a trip to Mars. Each team must decide what to take with them on a two-and-a-half year trip to Mars and whether their items will fit within the allotted...

A parachute is probably a good idea. An engaging lesson has pupils brainstorm ways to slow the descent of a falling object to minimize the impact when it lands. They decide on a design, build a prototype, test it out, and then make...

Here is a comprehensive and well-written lesson plan that results in learners building a standard wind turbine. Once built, teens can design a variety of experiments to test different factors. This activity is a noble undertaking that...

Ready, aim, fire! Launch to a new level of understanding as scholars build and test their own catapults. Learners explore lever design and how adjusting the fulcrum changes the outcome. 

How fun it must be to play Frisbee in space! That is just what a NASA engineer gets to do, and you can learn how, too. Follow the instructions provided in this informational article to create your own satellite launcher. Afterward,...

What do you call a story about a broken pencil? Pointless. Scholars may not be telling stories when using the resource, but they are solving optimization problems involving the maximum number of pencils that can fit on a tray. They...

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...

According to the movie Wildcats, "It's the sport of kings, better than diamond rings, football!" It is also, however, the sport of severe concussions and ongoing blows to the head. In order to keep our Seahawks soaring and Broncos...

Class members work in pairs to build a catapult to launch a grape a given distance. The catapult project, a compound machine, reinforces pupils' understanding of simple machines.

Which modification is the best? Using the scientific method, pairs determine the effects of each control surface on the distance of a glider's flight. The activity, section 16 in a 22-part unit on aviation, allows pupils to gain a better...

The classic egg-drop experiment gets a new bounce with an activity that asks pairs to design a lander similar to one used to land a rover on Mars within a fixed budget. The activity provides a great introduction to the idea of...

Provide a Hooke for a lesson on elasticity with an activity that has groups investigate a set of springs. They use a set procedure to collect data to calculate the spring constant for each spring using Hooke's Law. The groups...

It's important to make sure houses can withstand winds. A hands-on activity has learners create a structure out of household materials. They use a fan to simulate hurricane-force winds to see if their structures can withstand the...

Building an accelerometer app for your Android device. Groups develop an app that uses the accelerometer on an Android device. The purpose of the activity is to reinforce the programming design. The post activity assessment challenges...

Sometimes we all need a helping hand. Scholars get together to lend a hand in creating an assistive device that must be able to grab a hard-to-reach object. Now that's some help we could all use!

Waxed paper, newspaper, or aluminum foil? Keeping an ice cube from melting may require one or more of these materials. Learners design a box that will provide insulation so an ice cube stays intact for at least 90 minutes.

Solar energy is an amazing alternative ... but, not always particularly portable! Challenge young scientists to a folding solar panel build-off with an easy-to-execute activity. Scholars brainstorm around specific design needs, construct...

Working with a map that does not have a coordinate system on it, small, collaborative teams must come up with a coordinate system for their map. Groups then explain their coordinate structure to the class.

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.

Let your class become master builders. Scholars use Legos® or K'nex® pieces to create a structure that looks like an actual building in existence. The time limit is 12 minutes, so you better start building!

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.

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!

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...
