Teach Engineering: Trebuchet Launch
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....

Teach Engineering: You've Got Triangles!
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...

Teach Engineering: On Track Unit Conversion
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...

Teach Engineering: The Portable Fluid Power Demonstrator (Pfpd)
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...

Teach Engineering: Keep It Hot!
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.
TeachEngineering
Teach Engineering: Sliding Textbooks
In this culminating activity of the unit which highlights how forces play a role in engineering design and material choices, students explore and apply their knowledge of forces, friction, acceleration, and gravity in a two-part experiment.

Teach Engineering: Let the Blood Flow
Students work as biomedical engineers to find liquid solutions that can clear away polyvinyl acetate polymer "blood clots" in model arteries (made of clear, flexible tubing). Teams create samples of the "blood clot" polymer with...
TeachEngineering
Teach Engineering: Measuring Lava Flow
Students learn how volume, viscosity and slope are factors that affect the surface area that lava covers. Using clear transparency grids and liquid soap, students conduct experiments, make measurements and collect data. They also...
TeachEngineering
Teach Engineering: How High Can a Super Ball Bounce?
Students determine the coefficient of restitution (or the elasticity) for super balls. Working in pairs, they drop balls from a meter height and determine how high they bounce. They measure, record and repeat the process to gather data...
TeachEngineering
Teach Engineering: Fun With Air Powered Pneumatics
Working as engineering teams in this introductory pneumatics lab, students design and build working pneumatic (air-powered) systems. The goal is to create systems that launch balls into the air. They record and analyze data from their...
TeachEngineering
Teach Engineering: Slow the Cylinder
Students learn why shock absorbers are necessary on vehicles, how they dampen the action of springs, and what factors determine the amount of dampening. They conduct an experiment to determine the effect of spring strength and port...

Teach Engineering: Maze Challenge
As the first engineering design challenge of the unit, students are introduced to the logic for solving a maze. student groups apply that logic to program LEGO MINDSTORMS NXT robots to navigate through a maze, first with no sensors, and...
TeachEngineering
Teach Engineering: Hare and Snail Challenges
Students extend the ideas learned in the maze challenge in this unit with a focus more on the robot design. They learn how to design the gear train from the LEGO MINDSTORMS NXT servomotor to the wheel to make the LEGO taskbot go faster...
TeachEngineering
Teach Engineering: Sumobot Challenge
Students apply their knowledge of constructing and programming LEGO MINDSTORMS NXT robots to create sumobots- strong robots capable of pushing other robots out of a ring.
TeachEngineering
Teach Engineering: Line Follower Challenge
Student groups are challenged to program robots with light sensors to follow a black line. Learning both the logic and skills behind programming robots for this challenge helps students improve their understanding of how robots work, and...
TeachEngineering
Teach Engineering: Navigating a Maze
Students program LEGO MINDSTORMS NXT robots to go through a maze using movement blocks.
TeachEngineering
Teach Engineering: Wait Program!
After completing an associated lesson, students test their understanding in two programming tasks that utilize LEGO MINDSTORMS NXT robots and sound/touch sensors. Students gain practice in the iterative design-program-test-redesign process.
TeachEngineering
Teach Engineering: Using Waits, Loops and Switches
Students incorporate their knowledge of wait blocks, loops, and switches into their programming of the LEGO MINDSTORMS NXT robots to perform different tasks depending on input from a sound sensor and two touch sensors. This activity...

Teach Engineering: That's Hot! Robot Brain Programming
With the challenge to program computers to mimic the human reaction after touching a hot object, students program LEGO robots to "react" and move back quickly once their touch sensors bump into something. By relating human senses to...
TeachEngineering
Teach Engineering: Commanding a Robot Using Sound
Students continue their exploration of the human senses and their engineering counterparts, focusing on the auditory sense. Working in small groups, students design, create and run programs to control the motion of LEGO TaskBots. By...
