Composites
Source Institutions
In this activity, learners explore how composites work by creating and testing their own composite for an imaginary company.

Stem Cell Differentiation Game
Source Institutions
This game uses a modified Uno deck to review concepts related to stem cell research and diabetes.

Radiohead
Source Institutions
When you teeth clatter, they make quite the racket disproportionately to how much they actually sound to someone else.

Personal Pinhole Theater
Source Institutions
Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

Chocolate (Sea Floor) Lava
Source Institutions
In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

Resource Hunt
Source Institutions
In this activity, learners explore nonrenewable resources and learn why these resources are finite.

Balloon in a Flask
Source Institutions
Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.

Control a Bird’s Flight
Source Institutions
In this engineering design challenge, learners make a bird and then control its flight with attached strings.

Homemade Rain Gauge
Source Institutions
In this activity, learners will build rainwater collectors to practice meteorology in their own backyard. Collect and analyze data to determine how much rainfall you get in a set period of time.

Powdery Mildew Fungi: Classification and Ecology
Source Institutions
In this laboratory exercise, learners will discover how many different plant hosts they can find that are infected by the same genus of a powdery mildew fungus, or how many different genera of powdery

Rutherford Roller
Source Institutions
In this activity, learners make a black box device that serves as an excellent analogy to Rutherford's famous experiment in which he deduced the existence of the atomic nucleus.

Build A Dome
Source Institutions
In this activity, learners explore the structural strength of triangles by creating their own free-standing geodesic dome out of plastic straws.

A Simple Escapement Mechanism
Source Institutions
In this activity, learners build a simple mechanism that regulates the "escape" of energy released by a falling weight by portioning it into discrete amounts.

Spinning Illusions
Source Institutions
In this activity, learners construct three optical illusion toys to examine how our brains play tricks on what we see.

Leaning Tower of Pasta
Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

Motor Learning
Source Institutions
In this activity (26th on the page), learners construct an easy-to-build device and test motor learning.

Swing in Time
Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.

Mirror Image
Source Institutions
In this activity, learners investigate procedural memory.

Mitten Challenge
Source Institutions
In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.

Plastics the Second Time Around
Source Institutions
In this activity, learners test and compare the physical properties of thermoplastic polymers. Learners compare different plastics based on their color, degree of transparency, texture, and density.
