How does the length of a piece of string or rope vary with the number of knots tied in it? I came across this question a few months ago and decided to try it out as an investigative activity to help A-level Physics students revise some basic practical skills. I’ve since seen other Physics teachers, like Frank Noschese, tweet about using it in class. What’s the relationship between the number of knots and the length of the rope? Great #modphys graphing lab I learned from @hbarphysics! pic.twitter.com/jPlA1xdp1o — Frank Noschese… Read more A knotty problem →

I’m teaching the AS content for the AQA Physics A-level for the second time this year, and have recently had my students carry out the core practical to “find a value for g using a free fall method”. I used the same approach as I used last year, using a “g-ball” as shown in the video below, but have simplified the worksheet that I used. (The one I used last year asked the students to carry out parts of the uncertainty analysis as they were going along, whereas this one… Read more Finding acceleration due to gravity: take 2 →

I’ve found the videos below useful for showing my students how to read a vernier scale: Click here for a worksheet to practise reading these scales. Click here for online practice questions

It’s important that A-level Physics students can handle numbers in standard form and use prefixes with units. Below are some resources students can use to help them revise these skills: Video on how to convert numbers into / from standard form: Click here for online questions to practise converting to and from standard form.

I’ve just started teaching my second lot of year 12 students the new (AQA) Physics A-level. I believe the move from coursework / assessed practicals in the form of EMPAs etc. is… Read more Introductory A-level Physics Practical? →
