Using beams, connector pegs, and craft materials (such as foam and glue), students create a handle for a stamper. Students will need to build the handle and attach the foam shape. Students test it out by using ink and putting a stamp on paper.

In this activity students will construct a tower that is at least 4-6 inches high. The tower must withstand first the weight of a stack of books, then themselves and then you.
Concepts: 1) building
2) sturdiness

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

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 ...

Determine the best structure for a sturdy car. Motors do not have to be attached, but the car must roll with wheels and skid plates. To test the car design drop the car from a height of 4in to check if it survives.

In this activity, design and construct a chair that keeps Mr. Bear (a floppy stuffed animal) from falling backwards, forwards, to the left and to the right. The safety of Mr. Bear is in your hands.
See the "Chair for Mr. Bear" PDF for detailed instructions

In this activity, investigate different shapes in order to determine which shape is the strongest. Design and construct a number of roofs to be placed on a previously built house. Then test the structures by pushing on the top of the roofs.
