Students use data acquisition equipment to learn about force and displacement in regard to simple and complex machines. In the engineering world, materials and systems are tested by applying forces and measuring the resulting...

Using microphones connected to computers running Audacity software, student teams experiment with machine-generated sounds and their own voices and observe the resulting sound waves on the screen, helping them to understand that sounds...

After completing the electrical engineering project called Ant Bot, improve your machine and share your ideas with others.

In this activity, students learn about the trade-off between speed and torque when designing gear ratios. The activity setup includes a LEGO pulley system with two independent gear sets and motors that spin two pulleys. Each pulley has...

Students learn about gear ratios and power by operating toy mechanical cranes of differing gear ratios. They attempt to pick up objects with various masses to witness how much power must be applied to the system to oppose the force of...
