Egg Drop
Don't drop the ball on the resource ... drop an egg instead! A teacher-led demonstration has the class consider how to drop eggs into glasses when a tray is in the way. Hint: If you've ever seen a magician pull a tablecloth off a table,...
Teach Engineering
Energy Choices Game
Here's a fun game on a very serious matter. Scholars play a board game to learn about personal energy use and consumption. They see how various choices affect their energy use and costs, and then apply this knowledge to brainstorm ways...

Energy in Our Lives Carousel
Don't waste any more energy trying to find a great resource on energy. The third installment of a 25-part Energy Systems and Solutions unit focuses on energy use in pupils' lives. They consider how their daily routines consume energy and...
Teach Engineering
Energy Intelligence Agency
Protect the world from energy depletion—join the Energy Intelligence Agency. Using a set of cards, pupils distinguish between correct and incorrect information regarding energy use in the United States. They analyze graphs and diagrams...
Teach Engineering
Design a Flying Machine
Wrap up the unit in one final design. Pairs use their knowledge of aviation to design new flying machines and record how their designs take into consideration the forces that act upon airplanes. The pupils determine whether their designs...
Teach Engineering
Better By Design
Which modification is the best? Using the scientific method, pairs determine the effects of each control surface on the distance of a glider's flight. The activity, section 16 in a 22-part unit on aviation, allows pupils to gain a better...

Building-Testing-Improving Paper Airplanes: Head's Up!
Take foldables to all new heights. Pupils build and fly different types of paper airplanes in the 14th portion of a 22-part unit on aviation. Groups collect data on distance and flight time for each plane and compare the data from the...
Teach Engineering
What a Drag!
Stop and drop what is in your hand! Pupils investigate how form effects drag in the 12th part of a 22-part unit on aviation. Groups create equally weighted objects and determine which one falls the fastest by collecting data.
Teach Engineering
Bend That Bar
Bend it, but don't break it. Groups investigate the strength of different materials. Using a procedure in the seventh segment of a 22-part series on aviation, pupils determine how far a rod will bend. They determine the strength-to-mass...
PBS
Helping Hand
Reach out and grab something. Given the task of picking up objects at least two feet away, pupils design and build a grabber. The last activity in a series of five challenges requires learners to use information about fulcrums and levers.
PBS
Paddle Power
Potentially get all the way across the water. The fourth of five design challenges asks pupils to develop a plan for a paddle-powered boat that will store its energy. Given a limited number of supplies, the class members design, build,...
PBS
Zip Line
Slide all the way to the bottom. Using the design process, pupils create a carrier for a ping pong ball that will travel down a zip line. Learners test their carriers and determine solutions to issues they encounter to complete the third...
PBS
Paper Table
What is black and white and re(a)d all over? Class members build a table out of rolled newspapers. Pupils follow the design process to design, build, and test their paper tables in the second challenge in a series of five.
PBS
Watercraft
Whatever floats your boat—with some additional weight. The first activity in a five-part series challenges pupils to design a boat to hold pennies. Using the design process, learners design, build, and test their boats, making sure they...
