In this activity, learners build a game that tests their steadiness. Learners construct the game board by setting up an electrical circuit and a wand.

Before there were clocks, people used shadows to tell time. In this outdoor activity, learners will discover how to tell time using only a compass, a pencil, a handy printout, and a sunny day.

In this design challenge activity, learners design and build a circuit: an "electric highway" that connects a battery and buzzer at least three feet apart using four types of materials.

In this activity, learners explore electronic communication, the Morse Code system, and advances all the way through text messaging. Learners build a simple circuit, send messages to one another.

In this activity, learners make an electromagnet motor to demonstrate the most basic method of changing electrical energy into mechanical energy.

This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.

In this design challenge activity, learners invent a device that will make their friends and family ask, "What's buzzing?" Learners design an alarm with an on/off switch that is small enough to hide.

In this activity, learners actually feel the difference in energy required to light two different types of light bulbs: incandescent light and LEDs.

In this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.

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 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 about electricity, learners imagine that they are out in the wilderness and it is getting dark. Their task is to use the materials supplied to build a simple flashlight.

In this activity on page 12 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners examine how recyclable materials are separated by various properties at recycling centers.

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

Make a one-string "guitar" by stringing a cup with some fishing line. You amplify the plucking of the string by placing a piezo contact microphone and mini battery powered amplifier inside the cup.

In this activity, learners construct cars that are powered by hand-made, electric propellers.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

Build your own Mini Mini Golf Course and learn about hands-on building and design, basic circuitry, motion modules and more!

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
