Fun with Air-Powered Pneumatics
How high did the ball go? Engineering teams build a working pneumatic system that launches a ball into the air. The teams vary the amount of pressure and determine the accompanying height of the ball. An extension of building a device to...

Conservation of Mass
How do you teach a student with visual impairments about the conservation of mass? You use tactile models that represent the theoretical concept. Baking soda and vinegar are used to add gas to a deflated balloon. Learners will feel the...

Name That Frequency
How cool! This plan uses old cassette tapes to show frequency from traveling vibrations. To prepare for the lesson, tactile frequency diagrams are made and then placed near the video tapes or dominoes that are already set up. When they...

Design and Problem Solving
What if you had a design problem you wanted to solve, but were unable to draw because you were unable to see? Teach your learners with visual impairments that they can use Wikki Stix®, a braille ruler, Legos®, and Constructo Straws to...
Practical Action
Moja Island
Did you know that 1.3 billion people live without any form of electricity? Discover an array of possible renewable energy options by taking a trip to Moja Island, an online learning resource that will equip you and your learners with an...

Amusement Park Ride: The Ups and Downs in Design
Groups design the ultimate roller coaster by considering potential and kinetic energy. They test their designs using marbles and then go on to rate each group's design based on aesthetics, loop diameter, and cost.

Acoustic Mirrors
Investigate sound waves with acoustic mirrors. Using audio software, groups make recordings of musical instruments, both with and without acoustic mirrors. They compare the recordings to see the effect of acoustic mirrors on sound waves.

All Fats Are Not Created Equal
Apply robotics to connect physical properties to chemical properties. Future engineers use robots to determine the melting points of various fats and oils. The robots can do this by measuring the translucency of the fats as they heat up.
