Flashcards are a useful and effective way to revise things like equations and definitions. I know that a large part of the usefulness of flash cards is in the process… Read more A-level Physics Equations Flashcards →

This is my basic recipe for dal – it’s the one I cook when I need a fresh pot of dal quickly. Ingredients: 300g split red lentils 900 ml water… Read more Cheap, Easy, Quick Dal →

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 →

Every year, I send out a tweet asking UK sci-commers what they’re doing to mark Black History Month (BHM), and every year, I get the same lack of response which tells me that no-one is doing anything. This year, I don’t want to just send out my usual tweet because I suspect all it really accomplishes is to make a few more people in sci-comm dislike me. So, for the past few months I have been talking to lots of important, influential people who I think could make things happen… Read more Black History Month 2018 →

I recently read a “popular science” book on a topic that I felt I needed to learn more about. The book was well-written, ideas were clearly explained, and I finished… Read more Pop. Sci book or Textbook? →

One of the most important (and perhaps most counter-intuitive) ideas students need to grasp when learning about projectile motion is that the horizontal and vertical motion of a projectile are independent of each other. There are some lovely ways to demonstrate this, including the classic monkey and hunter demo, but here’s a quick and easy way to convince students of this if you don’t happen to have a brilliant technician:

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.
