Concentrated Solar Power
The seventh segment in an eight-part unit promotes the idea of concentrating the sun to increase the power of a photovoltaic panel. Pupils learn about devices used such as reflectors or lenses.
Teach Engineering
Surface Tension Basics
Back to the basics (of surface tension). The first installment of a nine-part series teaches young scholars about the basics of surface tension and how it relates to water droplets. They also learn how this concept allows for the...

Sugar Spill!
Sugar isn't good for you, but it's great for yeast! Scholars design an experiment to investigate how variables affect the rate of sugar consumption in yeast. The last installment of a nine-part Life Science unit considers how scientists...

Helping Hand
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!
Cold Spring Harbor Laboratory
Genes Can Be Moved Between Species
Biotechnology changes lives every day, but how did it all start? Learn about Cohen and Boyer's technique for recombinant DNA and the founding of this new scientific study. Then, scholars use the online interactive to discover how Hanahan...
Teach Engineering
When Silicon Talks
Explore Snell's Law using thin films. In the fifth installment of a seven-part series, pupils solve a set of problems relating to Snell's Law and use this skill during an experiment requiring the collection of reflective measurements...
Teach Engineering
Spring Away!
The last segment of the nine-part unit makes a connection between springs and linear equations. Groups hang weights from the spring and measure its length. Then, using the data collected, they calculate the slope to find the k-value of...
IMAX
Hubble
Explore what it takes to service the Hubble telescope. In the set of three activities, groups investigate several aspects of the Hubble telescope, including robotic arms used during repairs, spacesuits, and extravehicular activity (EVA)...
Teach Engineering
Accelerometer: Centripetal Acceleration
Scholars build robotic arms that swing back and forth and use them to collect velocity and acceleration data. To analyze the results, pupils compare data to the equations for angular velocity and centripetal acceleration.

Working with Watermills
Water is a powerful force; harness it through watermills. The task at hand is to create a simple watermill that functions in flowing water for at least three minutes. Scholars work together in teams to design and construct such a...
DiscoverE
Keep-a-Cube
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.
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
Slime!!
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.
Teach Engineering
Boxed In and Wrapped Up
If cubes have the smallest surface area, why aren't there more cube-shaped packages? Scholars take a box in the shape of a rectangular prism, cut it up, and make new boxes in the shape of cubes with the same volume. They then brainstorm...
DiscoverE
Design a Folding Solar Panel
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...
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...
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...
Mojang
Minecraft – Pocket Edition
You don't have to be a Minecraft wiz to know that this app has great playability for your learners! As afterschool programs and classroom projects around the world demonstrate, this game goes well beyond placing blocks and traditional...
Mascil Project
House Insulation
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.
Messenger Education
Design Challenge: How to Keep Items Cool in Boiling Water
Keeping items cool in boiling water... what? This engaging activity challenges high school learners to build a container that keeps butter in a solid state when placing the container in boiling water. Groups use previous knowledge and...

Build a Better Candy Bag
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!
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.
