We’ve almost completed the Electronics unit. You might want to see how you are doing by clicking on the link below and downloading the booklet. The booklet contains statements you can tick off to record your progress and has extra homework questions at the back to test you further.
We started work on the Telecommunications unit last week. If you want to check your progress you can use the link below to download a summary booklet on Telecommunications. The booklet contains learning statements for you to tick off as you work through the course, along with extra homework questions to test how much you have learned.
I’ve uploaded a set of summary notes that you might find useful as you prepare for the end of unit tests on Using Electricity. Download the pdf file using the link below.
I forgot to say that the moonsaic project starts tomorrow. Get yourself a smart poster for your bedroom wall – and it’s free!
Last week we looked at using electricity to get things moving. We looked at examples of an electric bell and the movement of a current-carrying bar of copper in a magnetic field. We’ll be taking an electric motor apart this week to see how it works but in the meantime, here is a link to an animation of an electric buzzer (same idea as the electric bell).
If you want to read someone else’s explanation of how an electric motor works, you could go here or here. There are animations of a dc electric motor here and here (this is the example I used in class).
We have almost completed the Using Electricity unit. We will start looking at magnetism tomorrow as an introduction to movement from electricity. The closer we get to the end of a unit, the nearer we are to test time.
You might want to download a copy of this electricity revision booklet to help you check how well you understand the topics we have covered. It also contains some useful revision questions in the homework section.
I won’t mark any homework on useful circuits handed in after today.
We’ve been looking at the different properties of series and parallel circuits over the past week or so.Â Since there are only 91 days left until Christmas, I thought I would ask you all for some shopping advice.
I need a new set of Christmas tree lights.Â Should I be in the market for a set of lights built in series or parallel?Â Don’t forget to tell me what information influenced your choice!
