Students learn about traffic lights and their importance in maintaining public safety and order. Using a Parallax Basic Stamp 2 microcontroller, students work in teams on the engineering challenge to build a traffic light with a specific...

Students work as engineers to design and test trebuchets (in this case LEGO MINDSTORMS robots) that can launch objects. During the testing stage, they change one variable at a time to study its effect on the outcome of their designs....

Students learn about trigonometry, geometry and measurements while participating in a hands-on interaction with LEGO MINDSTORMS NXT technology. First they review fundamental geometrical and trigonometric concepts. Then, they estimate the...

Students use three tracks marked on the floor, one in yards, one in feet and one in inches. As they start and stop a robot specific distances on a "runway," they can easily determine the equivalent measurements in other units by looking...

Working as teams, students learn the basics of fluid power design using the PFPD as their investigative platform. Students will investigate the similarities and differences between using pneumatic and hydraulic power in the PFPD. While...

Student teams design insulated beverage bottles in this challenge, and test them to determine which materials work best at insulating hot water to keep it warm for as long as possible.

Students conduct an experiment to determine the relationship between the speed of a wooden toy car at the bottom of an incline and the height at which it is released. They observe how the photogate-based speedometer instrument "clocks"...

Students are introduced to the basic principles behind engineering and the types of engineering while learning about a popular topic - the Olympics. The involvement of engineering in modern sports is amazing and pervasive. Students learn...

Working as if they are engineers who work for (the hypothetical) Build-a-Toy Workshop company, students apply their imaginations and the engineering design process to design and build prototype toys with moving parts. They set up...

Students learn about the process of reverse engineering and how this technique is used to improve upon technology. Students analyze push-toys and draw diagrams of the predicted mechanisms inside the toys. Then, they disassemble the toys...

Students learn how engineers harness the energy of the wind to produce power by following the engineering design process as they prototype two types of wind turbines and test to see which works best. Students also learn how engineers...

By taking a look at the energy of motion all around us, students learn about the types of energy and their characteristics. They first learn about the two simplest forms of mechanical energy: kinetic and potential energy, as illustrated...

This unit covers introductory concepts of mixtures and solutions. Students think about how mixtures and solutions, and atoms and molecules can influence new technologies developed by engineers. The first lesson explores the fundamentals...

Create a creature that uses air to create motion with this challenge. Site includes tips, lesson plans, and a place for students to document their design process.

Build a machine that accomplishes a task in an inefficient way with this Rube Goldberg challenge. Find some tips and a place to document your engineering process on this site.

Using cardboard, popsicle sticks, rubber bands, and strings create a pine cone that opens and closes. This site contains lesson plans, tips, and a place for students to document their engineering design process.

Build a zoetrope machine where you can animate a facial expression and the machine plays the animation back with this site. Site contains lesson plans, tips, and a place to document your design process.

Using common household materials students are challenged to make a flying raptor and control its flight with attached strings. Site includes lesson plans, tips, and a place for students to document their process.
