"Kinematics is simply - the study of motion..." Today we are going to do an introduction to this unit and start learning some key concepts related to motion. The downloads are below...our first topic, after the introduction, is Vectors & Scalars Downloads / Lessons

1. Finish Concept Map (if not completed yesterday) 2. Work period: Review Package (+ additional review)- TEST on Tuesday, April 1, 2016 Generating Electricity in Sewers!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. http://magazine.good.is/articles/portland-pipeline-water-turbine-power 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.
Additional Resources The information will help you understand some of the energy sources that are on the list... CLICK HERE to get more information.
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? Instructions
The following three downloads are in the package you were given in class, but are also available for download below.
Building Simple Speakers (Motor Principle in Action!)Today we are building speakers and then learning about Faraday's Law of Electromagnetic Induction. Faraday's Law
Today we completed our investigation into Faraday's Law of Electromagnetic Induction and then we created some simple generators which use this principle. We will also look at how electricity is produced from hydro plants, fossil fuel plants and wind turbines.
QuizToday you will write the quiz on the basics of magnets and electromagnetism. You should know the basics of magnets, domain theory of magnetism, Oersted's principle, Right Hand Rules, electromagnets and the equation as well as the motor principle. Michael FaradayWatch the first part of E=mc2 (start at 4:56 and only the part on E - the Michael Faraday part). Learn about Michael Faraday's amazing discoveries and insights into the connection between electricity and magnetism and the development of the branch of physics called electromagnetism. Today we will complete the motor principle worksheet and build our mini-motors (see previous day for hand-out)
Work Period: today you will be completing the 3 example problems and then completing and handing in the 4 question electromagnet problems. Please make this very neat, show your work, include units and box your final answers. Newton's Dark SecretsYour homework (or in class after you have completed the assignment) watch the video below and answer the questions on this sheet: Newton's Dark Secrets - Handout Today we are doing a few things. We will start with a lesson about Solenoids / Helixes (coiled wires) and how the RHR for current carrying conductors works when you coil a wire up. SPOILER: It is just Oersted's principle in action, but we get field amplification! 1. Electromagnet Lesson & Electromagnet Problems 2. Learn about and use the electromagnet equation.
