By the end of this module, the students will be able to explain (using physical models and computer simulations) the components of electrical circuits, the purpose of each component, and the differences between series and parallel circuits.This module was developed by Christina Owens as part of a Virginia Commonwealth University STEM initiative sponsored by the Virginia Department of Education.

The students will learn about how circuits work within a computer to not only turn the computer on, but to store/recall data, run applications, and in general respond when the mouse is clicked or a key is pressed (input/output), etc..This lesson can be created as a class with the teacher demoing what the students tell him/her/them to do or if there are enough kits students can work with partners/small groups/indivdually to create circuits and draw conclusions about how computers use circuits to operate efficiently.Suggestion:  Use this link to share with students how circuits work within the computers to store and recall memory to inspire their connective learning more :) start about 3:54 until 7:19.  This information will help students understand how electical currents are used to store information,  but also be able to make connections with what also happens when a key is pressed or the power is turned on and electricity flows through the open circuits within the computer's operating system (hardware).Video Link: https://www.youtube.com/watch?v=0A1e8eceIsY   

See how the equation form of Ohm's law relates to a simple circuit. Adjust the voltage and resistance, and see the current change according to Ohm's law. The sizes of the symbols in the equation change to match the circuit diagram.

In this assignment, students will use their knowledge of simple and parallel circuits to design and build a picture or card with a working light-up component. Students will need to work collaboratively and problem solve to accomplish this task. Through lots of trial and error students gain a much better understanding of conductors, switches, the semiconducting properties of LED bulbs, parallel circuits, and short circuits.

See how light knocks electrons off a metal target, and recreate the experiment that spawned the field of quantum mechanics.

Dope the semiconductor to create a diode. Watch the electrons change position and energy.

Why do the lights turn on in a room as soon as you flip a switch? Flip the switch and electrons slowly creep along a wire. The light turns on when the signal reaches it.

Provided basic circuitry materials, including a multimeter, students experiment through guided inquiry to gain hands-on experience with Ohm's Law and Equivalent Resistance.

When you think about moving, what comes to mind? Most of us think about using our muscles. But what tells your muscles to move? Your brain! Join Dr. Catherine Franssen, a resident scientist at the Science Museum of Virginia, as we investigate how your brain senses the outside world and helps you walk, run, swim and toss a ball. Movement can even make your brain think better! Along the way, we will explore the different areas of your brain and create a model brain out of dough.
