=UNIT TWO: ENERGY =

Here is our unit planner for energy:



=WEEK ONE: =

Our first focus in this unit will deal with electrical energy and how it an electrical current travels around a circuit (a pathway through which electrical current can flow):

**__Lesson 1:__** How to draw a circuit 

**__Lesson 2:__** Series Circuits 

**__Lesson 3:__** Parallel Circuit  Here's a copy of the circuit homework if you missed it/lost it:

__**Lesson 4: **__ Electric current 

Use this simulation to create a simple circuit. Test the amperes and voltage at different parts of the circuit pathway.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">Then you will need to create a series circuit. But first, ask yourself- how will the second resistor affect the brightness of the biulbs in the circuit? What will happen to the volatge and amperes in different parts of the circuit?

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">Create a series circuit. Make a note of how the brightness, voltage and amperes change (if they do change) in different parts of the circuit.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">Create a parallel circuit. Make a new set of observations

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">Here is a short interactive animation on magnetism: [|Magnetism]

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">In order for you to have a more complete understanding of the basics, here is a rather long (over 30 minutes) video which details the essential concepts that we will study in class. Don´t be put off by the length or its age. It is a very good general description of the process you need to know:

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">Note that no matter what type of energy is involved, it cannot be magically created... it must come from a source.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">As humans, we use energy to power almost all the aspects of our lives. Electrical energy, as we have seen is of particular importance and we need to be careful about how we use and from what source we obtain this energy.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">Energy can be defined as the capacity of a physical system to do work. <span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">It is also vitally important to understand that energy can neither be created nor destroyed. It is simply transformed from one type to another. For example, plants can transform light energy to chemical energy through the process of photosynthesis and this allows them to feed themselves. Potential (stored) energy in an object raised above the ground is converted into kinetic (/moving) energy when the object is allowed to fall back to the floor. <span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">Have a look at the video below: media type="custom" key="24880098" align="center"
