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 and construct an RCX or NXT crane controlled by motors and a touch sensor remote control.
See "Crane" PDF for detailed instructions.

In this activity, design and construct an RCX car that can bridge a one
foot gap without falling.

In this activity, design and construct an RCX fan with 2 touch sensors
and program it to run at variable speeds and have a stop/start function.
See the "Fan-Tastic" PDF for Detailed Instructions

In this activity, design and construct an NXT fan with 2 touch sensors
and program it to run at variable speeds and have a stop/start function.
See the "Fantastic - NXT" PDF for detailed Instructions

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.

Using a sound sensor and an NXT car, design a robot that moves forward when a person claps somewhat softly, and stops when a person claps loudly.
