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...

To learn about application of electrical engineering, this lesson requires the students to build a game similar to Operation. An open circuit is created. One end is a wire maze made of a bare wire. The other end is a loop of bare wire attached to a popsicle stick. The object is to guide the loop...

This activity is an introduction to building with the NXT or RCX. Have the kids build a vehicle without motors that will roll down a ramp. The objective is to have the car roll as far s possible. Make sure to introduce concepts such as gravity, friction, and sturdy building with the legos.

Filter dirty water and then measure the turbidity of the water. We gave the students the decision to choose two of three of the following materials to put inside a cup with a hole in the bottom: cotton balls, gravel, and coffee filters. They used two of these materials and built a filter around the ...

For this activity you will need an NXT brick, a wire, an NXT proximity sensor, and computers running MINDSTORMS

1. Have student design an alarm box that will detect when a person approaches the box. If students want to use more than one proximity sensor or a different sensor as we...

This is a great introductory activity to mechanical engineering. Simple machine kits were used to create sturdy carts, which would transport a pumpkin (orange marble) and its passenger (lego figurine) down a ramp.

In this activity, use an NXT and a light sensor to collect data about the light conditions of the room. Can you find light sensor readings in the range of 0-30? 60-90? 90-100? Draw conclusions and make generalizations about light intensity in the room.
