Learners make a circuit board that has questions and answers. When the correct answer is chosen for a question, a circuit is completed and a light illuminates.

In this activity, learners demonstrate and discuss simple circuits as well as the differences between parallel and serial circuit design and functions.

In this activity about magnetism (page 11 of the pdf), learners will experiment with magnets to explore how opposite poles attract and similar poles repel in magnetism.

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

In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.

In this activity, learners explore electricity and conductivity to find that many things conduct electricity including copper, pencil lead, fruit, play-doh, and even people!

In this activity, Frankenstein's lab is running out of electricity! Learners use fruit to help Igor find a temporary source of energy to turn on a light.

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.

Make your own speaker with a magnet, wire, and paper cup! If you have a radio with a headphone plug and an old pair of headphones, this is a great tinkering activity.

Did you know that some breakfast cereals are fortified with ferric phosphate, while others contain tiny pieces of reduced iron?

In this activity about magnetism (page 17 of the pdf), learners experiment with magnets, exploring the concept of diamagnetic materials by seeing how a grape reacts to a magnetic field.

Learners observe an electrochemical cell constructed from a small jar containing zinc and copper strips immersed in separate solutions. The strips are connected to a motor that turns a small fan.

This is a perfect summertime lunch activity! Pico Cricket is required (micro controller). First, get a bunch of cut up fruit, line them up, then plug a piece of fruit with a Pico Cricket sensor clip.

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.

Margaret Pezalla-Granlund, a Minnesota artist, came up with this really fun and surprising activity using graphite from a pencil, connected with a Pico Cricket to tell a story: "The first time I saw s

In this activity, learners explore how a flashlight works, showing the electric circuit and switch functions of this everyday household item.

In this activity, learners use a pencil, magnets, and mat board to illustrate Newton's Second Law.

In this experiment related to plant biotechnology, learners discover how to prepare and load an electrophoresis gel.

In this activity, learners use colored candy to represent subatomic particles and make a model of an atom (Bohr model).

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.
