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.
Giving Water the Treatment
Source Institutions
In this ecology activity (page 8 of the PDF), learners explore how to filter contaminated water using a variety of materials.
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.
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.
Squidgy Slime
Source Institutions
In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.
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.
Wind Tunnel Testing
Source Institutions
In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.
Life Vest Challenge
Source Institutions
In this activity, learners explore the engineering behind life vests or personal flotation devices and the challenges met by these devices.
Rubber Band Boat
Source Institutions
In this activity, learners build styrofoam boats powered by twisted rubber bands.
Puff Car
Source Institutions
In this activity, learners are challenged to design a wind-powered car using only a handful of household materials.
Milk Plastic
Source Institutions
In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.
Clipper Creations
Source Institutions
In this activity, learners create a working model of a nail clipper. This activity helps learners learn the basic principles of simple machines, engineering design and model building.
Target Practice
Source Institutions
In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.
Gumdrop Dome
Source Institutions
In this engineering activity, learners construct sturdy geodesic structures out of gumdrops and toothpicks. Use this activity to explore engineering principles as well as sturdy shapes and triangles.
Ships Ahoy!
Source Institutions
The goal of this activity is to design the fastest sailboat or one that carries the most treasure.
Hand Biometrics Technology
Source Institutions
In this activity, learners explore how engineers incorporate biometric technologies into products as well as the challenges of engineers who must weigh privacy, security and other issues when designin
