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 build simple alarms that they can attach to anything, such as a drawer or doorway. This activity introduces learners to electricity, circuits, and currents.

In this activity, learners construct drawing machines using a cup, some markers, and a battery pack. The markers act as "legs" for the machine, making a drawing that records as it moves.

In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

In this technology activity, learners build an "alarming" doormat to keep siblings out of their rooms. Use this activity to teach learners about circuits, switches, and sensors.

In this design challenge activity, learners investigate series circuits and motors to build a hand-held "kick stick." Their goal is create a battery-operated device that sends a Ping-Pong ball across

In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.
