What is Going on with Grandma?
Pupils individually determine what they need to know about osteoporosis and how they will find that information. They share their thoughts with a partner before moving on to share with the class. The class arrives at a list of a set of...

Puff Mobiles
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...

Energy on a Roller Coaster
Roll with your class into the idea of conservation of energy. Pupils use a roller coaster track to collect data to reinforce the concept of conservation of energy and the influence of friction. Class members then create a graph from...

Making Model Microfluidic Devices Using JELL-O
Nothing flows like J-E-L-L-O! In the final portion of a four-part series, pupils create scale models of microfluidic devices out of gelatin and bendable straws. They use their devices to test various flow rates in the delivery of...

How Big? Necessary Area and Volume for Shelter
Teams must determine the size of cavern needed to house the citizens of Alabraska to protect them from the asteroid impact. Using scaling properties, teams first determining the number of people that could sleep in a classroom and then...
Curated OER
Manipulating Digital Images
High schoolers work with pre-loaded images as well as with a digital camera to manipulate digital images. At the end of the lesson, they analyze and write about their work using complete sentences, correct grammar, and spelling. For a...

Stop the Stretching
Stretch your teaching repertoire with an experiment on the elongation (stretching) and failure (break) of several materials. The point of the experiment is to design a composite material for chair webbing.

Understanding the Design Process
Can you build a better mousetrap? Broken into two sessions, this plan introduces learners to the design process. The first session has pupils look at the world through a design perspective by redesigning everyday objects. In the second...

Build a Plankton Net
Give household materials new life by turning them into a plankton net. Scholars design and build a net to collect and filter plankton from water. They test out their creations by using glitter to represent plankton. The nets need to...

Build a Pinball Game
Watch your classroom turn into an arcade. Pupils work in groups to build pinball machines from boxes and other found objects. Gamers must incorporate a variety of obstacles and launchers into the machine to see their designs in motion.

Action Figure Diver
Will your next buoyancy lab rise to the occasion? Make a splash with action figure divers! Teams of young physicists explore the relationship between mass and buoyancy by adding weights or balloons to achieve a diver that neither sinks...

Heart Valve Replacement
Put your heart into it. Scholars design and build replacements for mitral heart valves. Obviously, they can't test their creations on a real heart, so a box with marbles (to represent blood cells) will suffice.

Electrical Liquids
Liquid or not, here comes the electricity. Scholars test the conductivity of various substances using a circuit that includes a light bulb. If the light bulb lights up, then the liquid is a conductor. What a bright idea!

Kicking Machine
Don't kick the resource to the curb; you'll definitely regret it. Future engineers devise a kicking machine that launches a ping-pong ball toward a target. They can use a pendulum, a rubber band, or both, depending on whether they want...

Penny Perfect Properties (Solid-Liquid Interations)
I can get more water to stay on a penny than you can! Collaborative pairs determine the volume of liquids that can be contained on the surface of copper pennies and plastic coins. The pairs analyze their results using graphs and go on to...

The Internet Is for Everyone
What is this thing called the Internet? A KWL activity elicits what the class knows about how the Internet works. Then pupils read a copy of a memo about the need to keep the Internet open and accessible by everyone.
Teach Engineering
Force on a Current Carrying Wire
What do electrical currents have to do with an MRI? Using a simple wire setup and a magnet, class members explore forces used in an MRI by investigating the magnetic force acting on a wire carrying a current.

Designing Highway Interchanges
How do engineers determine the most efficient highway designs? Introduce young scientists to the world of topology, the branch of mathematics that examines how things are connected. Teams use model highways to create the most...

Lego Structures
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!
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...
DiscoverE
Water Sampling
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.
DiscoverE
Ocean Acidification
Combat ocean acidification with bubbles. Young engineers create a system that reduces the acidity of water. Dry ice in water helps simulate ocean acidity, and blowing bubbles into the water results in a gas exchange that neutralizes the...

Air Train
Train your pupils to be master engineers. Young learners design a train that travels along a fishing line. The train needs to safely carry pennies as passengers without falling out.

Musical Vibes with Palm Pipes
Ancient people used musical pipes as early as the third millennium BCE. Young scientists explore the workings of musical pipes to better understand the relationship with frequency, length of pipe, and sound waves. They determine the...
