1. Sound display

    Sound display

    The idea of this challenge is to collect and display sound data from the NXT sound sensor in real time on the LCD display of the NXT. You could include the ability to pause data collection by bumping a button to “freeze” a particular screen of the data until another...

  2. Drive in a square

    Drive in a square

    The goal of this activity is to make a robot car drive in a square path. Hint: Rotation sensors are great for controlling the angle of a car’s turn. Resources Square lesson plan – NXT-G (PDF) Square lesson plan – RCX + ROBOLAB (PDF)

  3. Tunnel vision

    Tunnel vision

    Design and construct a car and program it to drive through a tunnel, automatically turn on its headlights when it enters the tunnel, and turning them off when it gets to the other side.       Tip: What kind of sensor would be suitable for detecting when the robot...

  4. Light sensor scavenger hunt

    Light sensor scavenger hunt

    How can you determine the light conditions in different parts of a room? Can you find light sensor readings in the range of 0-30? 60-90? 90-100? Can you draw conclusions and make generalizations about light intensity in the room?

  6. Light theremin

    Light theremin

    In this activity, use an NXT brick equipped with two light sensors to emulate a theremin. One sensor will change pitch as the amount of light sensed changes, and the other sensor will change volume as the amount of light sensed changes. The theremin is meant to be controlled with the...

  7. Science through LEGO Engineering

    Science through LEGO Engineering

    The following four curricula are designed to introduce students (in Grades 3 to 5) to various science concepts through design-based LEGO projects. The first several lessons of each unit engage students in scientific explorations sometimes using the LEGO tool-set as a resource. The students are then charged with an open-ended...
