Beat the Clock: Sorting Networks
Source Institutions
Even fast computers are limited to how quickly they can solve problems. One way to speed things up is to use several computers at once.

Make a Model of a Home Made From Shipping Containers
Source Institutions
In this activity, learners watch a video to learn about a couple who built a home out of shipping containers in Brooklyn, New York.

Biomimicry: Synthetic Gecko Tape Through Nanomolding
Source Institutions
In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.

Make a Speaker
Source Institutions
In this activity, learners explore how an electromagnet works by making a simple one. Using this knowledge, learners design a diagram to make a working speaker using household materials.

Stabilization Wedges Game
Source Institutions
This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.

Round & Round
Source Institutions
In this activity, learners make and test fly paper helicopters. Learners use templates to create paper helicopters and then take take turns flying them in the air.

The Power of Graphene
Source Institutions
This lesson focuses on graphene and its electrical properties and applications.

Heat Capacity: Can't Take the Heat?
Source Institutions
Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

Family Flyers
Source Institutions
In this activity, learners work in teams to build and test paper airplanes. Learners try to fly their airplanes directly on the runway and earn points for accuracy.

Design and Build a Wind Vane
Source Institutions
In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.

Total Internal Reflection
Source Institutions
In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.

Biotechnology Through Time
Source Institutions
In this activity, learners investigate the history and development of agricultural biotechnology.

Metal Heads
Source Institutions
Pairs of learners play the roles of programmer and robot. The programmer gives specific directions to the robot to accomplish a simple task (e.g. walk across the room and pick up a pencil).

Build Your Own Hydroelectric Generator
Source Institutions
Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

Tools of Magnification
Source Institutions
In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.

Airfoils
Source Institutions
In this experiment, learners discover how an airfoil creates lift. Learners use simple materials to build an airfoil and test it at different angles to investigate Bernoulli's principle.

Weather Vane and Anemometer
Source Institutions
In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

Spring Scale Engineering
Source Institutions
In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.

Water Tower Challenge
Source Institutions
In this activity, learners explore how engineers work to solve the challenges of a society, such as delivering safe drinking water.

Sticky Engineering Challenge
Source Institutions
In this activity, learners explore how engineers work in a team to solve problems.
