In this underwater activity students build a boat with two motors and touch sensors that they must navigate through a small course.

NOTE: The RCX cannot be submerged in the water.
Propellers can be bought at http://www.hobby-lobby.com/boatprop.htm

This giant walking crab was built by the imagination of resident LEGO genius Carter. Using pneumatics, the crab walks with two 3-point movements (front and back leg of one side with the middle leg of the opposite side). A series of 4 motors perpetually pressurizes 3 air tanks supply the power. A mot...

In this activity students explore the concept of torque and build a "boat" with two propellers facing opposite directions. If you spread the motors apart the boat will spin faster and if you move them in it will spin slower. A great lead up activity to the Slalom Boating Activity also in this Underw...

Think about when you give students accessories and LEGO People. Kids can often get distracted with decorating over the goal of the activity. I give students people once they have passed whatever tests their creation needs to pass.

In this lesson students have to build a "spatula" (cantilevered beam) that can hold as much weight as possible. Students learn what makes strong and sturdy connections in LEGO building and can explore how cantilevered beams work.

This is part of the curriculum unit "Robotics: Assisti...

I find it helps to keep young children (early elementary) more focused on the task at hand if they only have access to the pieces they need. For example, I usually take the motors and battery packs out of the Simple Machine kits.

Objectives:
Kids will program motors to change direction 3 times using rotations, seconds, degrees, or unlimited DURATION and make a robot that does the Bunny Hop.
