Machines and Tools (Part 2)
Which pulley system will give us a whale of a good time? Teams compare the theoretical and actual mechanical advantages of different pulley systems. They then form a recommendation for how to move a whale from an aquarium back to the ocean.
Teach Engineering
Tools and Equipment (Part 1)
Looking for the best inclined plane for the job? Groups calculate the theoretical mechanical advantage for four different inclined planes. They determine the actual mechanical advantage by measuring the amount of force needed for the...
Teach Engineering
Just Plane Simple
It is plane to see that simple machines help reduce the force needed to perform a task. This resource introduces three of the simple machines--the inclined plane, the wedge, and the screw, and the formulas in order to be able to...

Induced EMF in a Coil Wire
Small groups investigate the interaction between a coil of wire and a magnet to create an electromagnetic field and observe the voltage they create. Through further interactions, they realize a conductor can be charged from the...
Teach Engineering
Slinkies as Solenoids
What does an MRI machine have to do with a slinky? This activity challenges learners to run a current through a slinky and use a magnetic field sensor to measure the magnetic field. Groups then change the length of the slinky to see the...
Teach Engineering
Biot-Savart Law
Electrical current going round and round,produces a magnetic field. After a demonstration of the magnetic field surrounding an electrical wire, class members use the provided formula associated with Biot-Savart's Law to calculate the...
Teach Engineering
Both Fields at Once?
An MRI uses both a magnetic and electricity, so how do the two interact with each other? Class members observe the effects on a charged particle when it is subject to both an electrical and magnetic field. The teacher background...
Teach Engineering
May the Magnetic Force Be with You
Class members use mathematics in order to better understand magnetic forces and their interaction on charged particles. After a demonstration of the interaction between a magnet and an electron beam using a CRT computer monitor, learners...
Teach Engineering
A Simple Solution for the Circus
Class members are challenged to design a device that will move a circus elephant into a train car. Groups brainstorm ideas that use simple machines to load the elephant. They then choose one of their ideas, sketch a plan, and present it...
Teach Engineering
Are We Alone?
Find an answer to the age-old debate of whether life exists on Mars. Groups determine criteria to help look for signs of life on Mars. The activity has the class simulate testing Martian soil samples for signs of life before drawing...

Manned Mission to Mars
To go or to not to go — the question for a mission to Mars. This resource provides details for a possible manned mission to Mars. Details include a launch schedule, what life would be like on the surface, and how the astronauts would...
Teach Engineering
Egg-cellent Landing
The classic egg-drop experiment gets a new bounce with an activity that asks pairs to design a lander similar to one used to land a rover on Mars within a fixed budget. The activity provides a great introduction to the idea of terminal...
Teach Engineering
The Great Gravity Escape
Groups simulate an orbit using a piece of string and a water balloon. Individuals spin in a circular path and calculate the balloon's velocity when the clothes pin can no longer hold onto the balloon.
Teach Engineering
Come On Over Rover
Introduce your class to the steps that occur in the manufacturing of parts, the assembly, and the testing of a Mars rover. Pupils learn about fabrication techniques and tolerances in the manufacturing process.
Teach Engineering
Strong-Arm Tactics
Experience collecting rock samples using a robotic arm with an activity that has pairs work together to operate a robotic arm. One pupil serves as the eyes and the other operates the controller. The objective is to be the fastest pair to...
Teach Engineering
Red Rover Robotics
Help your class understand the importance of exploration using robots. with a resource that provides a short history of robotics as a lead into looking at Martian robotic exploration missions. The activity specifically looks at the...
