Today is the electricity & magnetism test - good luck!!
Work period: Review Package - TEST on Friday, Feb. 27, 2015
Amazing Article about Electricity production by placing turbines and generators within sewer systems...read the article and watch the video and post a comment in this comment section.
Today we are completing our concept map on electricity production. You will take a picture of your finished work and post it in the comments section of this post. We will then start work on our review for this unit.
Today we will work a little on completing the Transformer Problems that we started on Friday (they are due tomorrow at the end of the day). We will also then start work on developing our Electricity Production Concept Map Activity.
The information will help you understand some of the energy sources that are on the list...

Transformers are used to step-up (increase) or step-down (decrease) voltage. They are extremely important in our everyday lives. They are used to step-up voltage at a power generating station so that electricity can travel long distances with very little energy loss (low current flow) to your neighbourhood and then is stepped back down so you can use it in your home at safe voltages and high current. They are used in your cell-phone and computer chargers as well - look at the back and you'll see. But...how do they work?

Today we wrote a basic quiz using the Electromagnet Equation and the basics of electromagnets. We then completed our investigation into Faraday's Law of Electromagnetic Induction and then we created some simple generators which use this principle.
Today we finished up our speakers activity (please post the video links in the comment section of this site).
Demonstration of Faraday's Law of Electromagnetic Induction - Your task: write out the definition of EMF and electromagnetic induction.
Newton's Dark Secrets - later in the year when we are learning about Newton we will refer back to this video and discuss the life of Newton.
