The mystery of Benham's Disk
Turn a CD into an excellent spinning platform. Spin the CD with the Benham’s Disk pattern on top and explore the interesting effect that happens. The spinning black and white pattern creates an illusion of seeing colors in the spinning disk. It also reveals an interes..
Sort animals by how they are born!
Students have fun using a model to sort animals into 2 categories: those born from an egg and those not born from an egg.
Curriculum topics: Biology, animals, sorting, classifying, patterning
Kit includes: 1 idea sheet, 1 3-ring binder, 1 3-ring pencil pou..
What can keep a simple structure from collapsing during an earthquake?
How will an earthquake, simulated by shaking, affect a "building" made of linked squares? How can the square "stories" be cross-braced to prevent the "walls" from collapsing? What dangers are there in building above a garage?..
Creating electrical circuits with simple materials
Provide students with opportunities to create a basic circuit, build a portable version, and explore parallel and series circuits!
Curriculum topics: Electricity, conductors, parallel and series circuits
Kit includes: Idea sheet, 10 foam ba..
What's all the buzz about?
Give this little noisemaker a whirl to learn about the effects of air passing over a taut rubber band. As it vibrates, the rubber band can generate a surprising range of deep rumbling tones. How can the pitch be changed? Experiment to find the answers.

A clever way to demonstrate the transfer between potential energy and kinetic energy
Create a model car consisting of a simple chassis and a straw-based axle system (simple machine) that produces minimal friction and allows the cars to roll with little energy input, making them ideal learning too..
Discover the rainbow of colors in white light!
White light is actually a combination of different colors. This easy-to-build spectroscope allows students to separate the incoming light into its component colors, forming a light spectrum (rainbow). Besides creating interesting color patterns it c..
Unique Connector + Pencils = Pom Pom Launcher
Many catapult designs have evolved over the centuries. The new connect-a-pult demonstrates common items being re-purposed with the aid of a little creative engineering. Even young learners can explore the effects of using different launch angles and ..
What makes this capsule jump like a critter?
Build student curiosity about motion, center of mass, and inertia with this fun activity! Use this activity as a tool to discuss the characteristics of living organisms. The reason for the capsule's tumbling motion is concealed by the foil which adds t..
A Glimpse into Cyber Security
Students build empathy around the concept of cyber security by learning about different types of data categories and by conducting research into how cyber security is addressed globally. Students to learn and apply concepts for creating effective account passwo..
Create sound from electromagnetic waves.
Create a working earphone by combining cup lids, a magnet, and a coil of magnet wire. The activity can be done as a step-by-step assembly or as a design exploration. Attach to a sound source and hear music from of a couple of cup lids!
How do you prevent a dropped egg from cracking up?
Students build a "vehicle" designed to prevent a dropped egg from breaking. In the process, they discover that combining simple materials with a little creative thinking and teamwork will reveal many ways to solve this intriguing challenge!
Simulate evolution with critters and beaky birds
Simulate evolution with some colorful “critters” and carnivorous “beaky birds”. Simulations are helpful to demonstrate processes like evolution that take place over many years. Observe how adaptations such as camouflage help organisms survive and p..
Have a blast with this gas-powered flyer!
These rockets enable students to use design thinking and are effective demonstrations of Newton’s laws of motion. The liftoff power of the rocket is produced by a common acid/base chemical reaction that creates carbon dioxide gas; making this activity an ..
Let a steel needle point the way!
The floating compass is a useful tool for detecting the magnetic fields of magnets and of the Earth. Make a simple compass with a magnetized needle demonstrates the properties of magnetic materials and shows that magnets have north and south poles. Using the floa..
