The ability to draw and interpret graphs is a skill which gets tested every year in the Junior Cert exam.
However I have yet to see a lesson-plan on this; usually each graph is dealt with separately in its corresponding chapter. Which is why the revsion page of thephysicsteacher.ie now offers a guide to answering graph questions in the exam. It includes a full set of graph questions taken from past-papers at higher and ordinary level.
Each graph is explained and solutions provided, including an emphasis on the importance of knowing the formula for calculating the slope, the significance of a line going through all data points and the origin, and the trick to drawing a ‘best-fit’ line (this is not on the syllabus but is only one more example of something not on the syllabus coming up on the exam paper).
There is no password required to access the resource, no log-in process, no funny handshake, no ‘you show me yours and I’ll show you mine’. As always, feel free to take it, adjust it and make it your own – life is too short to do otherwise. Make no mistake – this will be very useful to most students. All I ask is that you follow the suggestion on the top of the first page and photocopy A3 – A4 (this puts two pages onto one) and then use front and back of the page to save paper.
There are a couple of other resources on the revision page and one or two more which should be completed and uploaded in the near future – stay tuned.
