Electrical Circuits


In this unit students will build electrical circuits using LEDs, batteries, resistors, jumper cables, solderless breadboards, buzzers, potentiometers, thermistors, capacitors, and more.  Students will learn the difference between a circuit wired in series and one wired in parallel. Current, voltage, and resistance will also be discussed in their relation to Ohm's law.

Review of Atoms


If you aren't familiar with atoms, electrons, protons, and neutrons, you'll want to watch this first video (What is an Atom) before we begin.  Pay extra close attention to the discussion  
of electrons as they will be very important to our discussion of electricity.  If you have any questions, please ask Mr. Capretto.  We will be 
discussing the video as a class after everyone has watched it.  If you would like more information on atoms, feel free to watch the following video from Crash Course.  It is part of an entire series on Chemistry.

Introduction to Electricity

Once you learned more about electrons you'll want to familiarize yourself with the basics of circuits.  Open and flip through the Electricity Book part 1 and part 2.  Be sure to click on the interactive elements of each screen.  When you finish each part, be sure to take the quiz below.  Don't panic, its not graded!  The electricity book part 1 has a quiz built in to it, so you can skip that quiz and take my quiz below.

Insulators and Conductors

You might already have some basic understandings of insulators and conductors.  Nevertheless, please take some time to research insulators and conductors so that you can complete the quiz below.  That's right, I'm telling you to google it.  

Batteries

It is no news flash that batteries power our electrical devices, but how exactly do they work.  Check out the videos below to find out.

Breadboards

From their beginnings as repurposed cutting blocks, today's plastic breadboards make it possible to quickly and easy connect multiple components together to form a circuit.  Prototyping, building an early model to test an idea, is the first step to inventing new technology.  With the aid of solderless breadboards, amateurs 
 and professionals, are able to map out the electrical circuits before the more costly process of manufacturing printed circuit boards (PCBs).
