series or parallel?

We’ve been looking at the different properties of series and parallel circuits over the past week or so.  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.  Should I be in the market for a set of lights built in series or parallel?  Don’t forget to tell me what information influenced your choice!

If you’re not sure why the series/parallel decision would make a difference to tree lights, you might want to check this site.  There’s also some information on series and parallel circuits here.

Traffic Light Chart

traffic light chartI’ve used the traffic lighting information you provided in your jotters to draw a bar chart showing how comfortable our class feels about each of the success criteria.

If you want to read the text along the x-axis, just click on this pdf version of the traffic light chart. You will be able to zoom in using Acrobat’s zoom feature and read the full text label for each of the criteria (get Adobe Acrobat Reader here).

I will address the topics attracting the highest red scores first, so we will start with “know that the declared value of an alternating voltage is less than its peak value”. We will start a lesson with this topic in the next week.

Back to School

We’ve nearly finished the first week of term. Hopefully your timetables are all sorted and you are starting to get back into the learning routine again 😉

Feel free to use this site to remind yourself what we have worked on during the week, last week or last month as we work through the Standard Grade course. There are categories down the side menu to guide you to the correct course unit, along with links to other sites you might find useful. I will add updates as we cover new topics. You can ask questions or start discussion by posting comments. (Rude comments will be removed!)
