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, design and construct a windsail mechanism connected to a rotation sensor and an RCX to measure the speed of the wind.
See "Capture the Wind -RCX" PDF for detailed instructions.

In this activity, design and construct a windsail mechanism connected to
a rotation sensor and an NXT to measure the speed of the wind.

In this activity, design, construct and program an RCX or NXT dancing
robot that has at least two moving parts and at most two motors. Set your
robot's dance to music.

In this activity, design and construct an RCX car and program it to run
for varying lengths of time. The distances that the car travels will be
recorded and plotted into a graph to determine how long the car will need
to travel in order to make it stop as close to a randomly pla...

In this activity, design and construct an NXT car and program it to run for varying lengths of time. The distances that the car travels will be recorded and plotted into a graph to determine how long the car will need to travel in order to make it stop as close to a randomly placed LEGO person as po...

In this activity, design and construct an RCX or NXT car and program it to enter
a tunnel, then reverse back out when it encounters a darker light reading.
See the Activity PDF's for detailed instructions.

In this activity, set up an NXT “voting booth” to gather data using touch sensors. The presses will be recorded and plotted into a graph.

In this activity, set up an RCX “voting booth” to gather data using touch sensors. The presses will be recorded and plotted into a graph.

In this activity, design and construct an RCX tractor that is capable of pulling a heavy load across a floor. (NOTE: Gears will be needed.)
