In my physics class, the students modified their "Going the Distance" robots to push on a ball. This was an opening activity for my "Force and Motion" unit. We used some fabric taped to the floor as a hole.

In my physics class, my students create physical pendulums to study oscillations. They use the NXT and a light sensor to test their predictions regarding the period of the pendulum's oscillation

In a first grade class, students built cars using motors, pulleys and basic bricks. They added plows to the front to clear the "snow".

Today you won't have troubles to buy an electronic compass from the shelf. But, sometimes you want to understand - or as a teacher - to explain how the compass direction can be turned into digital information. This sensor got its name, because it is made of a few LEGO pieces, the RCX, a magnet, a li...

The aim of this project is to show the nonlinear dynamics of a vertically driven pendulum using Lego NXT. I use this toy in my Nonlinear Dynamics classroom.

Below you find building instructions and a video of the toy.

A pendulum with a fixed suspension point has two eq...

Acceleration is a physical concept that is difficult to understand, although you can feel
it when driving on a roller coaster. This sensor might help kids to realize how
acceleration can be quantified. It got its name, because it is made of a few LEGO pieces,
the RCX, and some n...

In this lesson, students will design and build a wheelchair that can hold a load about the size of a water bottle. Students will build their wheel chairs using the engineering design process and must follow specific design requirements.

This is part of the curriculum unit “Robot...

Eighth-grade students built LEGO balances that were accurate to within half a gram.

Eighth-grade students built LEGO balances that were accurate to within half a gram.

In this activity, the students first choose an animal that they want to create and think about the types of motion that the animal does. Then, they approximte the animal's motion using gears and motors. This is a good way to use gears and motors in a situation other than a car. At the end, present y...
