In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.

In this activity, learners create night lights using a plastic cup, programmable PICO Cricket, tri-color LED, and sensor.

In this activity, learners explore computer programming and the impact of computers on society. Learners build and test a program to turn a light on and off using an Arduino board.

In this activity, learners construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket.

In this activity, learners create a marble maze that contains sensors. As a metal marble triggers the sensors, the Pico Cricket turns on lights or spins motors.
