Andy Darvill's TES stuff

I've been teaching science/physics for quite a while, and written lots of stuff along the way. Much of what I've written is for Nelson Thornes, OUP and SamLearning, but here are some things that are properly mine and I can publish here. Hope you find them useful. At www.darvill.clara.net you'll find some more items, and minisites about gcse radioactivity, energy resources and the electromagnetic spectrum which can occupy a class for a whole lesson and more.

Lenses - how to draw ray diagrams

Lenses - how to draw ray diagrams

(0)
This powerpoint and worksheet walks students through the procedure for drawing ray diagrams for gcse. It refers to the AQA OUP textbook, but the activity itself is self-contained.
Intro to the gcse wave equation

Intro to the gcse wave equation

(0)
The wave equation “velocity = frequency x wavelength” tends to terrify students. This activity takes most of a lesson, and walks them through it so they can interpret exam questions and know what they’re looking at.
Radioactivity - Properties of alpha, beta and gamma

Radioactivity - Properties of alpha, beta and gamma

(2)
An overview of the properties of alpha, beta and gamma radiation. The sheet consists of a blank table with jumbled answers underneath for pupils to sort. I use it during the first lesson of the topic where I show the class radioactive sources and what happens when you put paper/aluminium/lead in front of them. See www.darvill.clara.net/nucrad for more gcse radioactivity stuff.
Falling Cupcake Cases Investigation

Falling Cupcake Cases Investigation

(0)
Structure for an investigation taking 2~3 lessons. Suitable for KS3, 4 or 5 depending on how deep down the rabbit hole you want to go, colour-coded slides steer you to KS3/4 or KS5. Method: drop a cupcake case. Measure the speed of fall. Now put another cupcake case inside the first. has the speed of fall changed? How much? What about 3, 4, 5, …10 cupcake cases? Is there a relationship between number of cases and speed of fall? Is it proportional? Simple on the surface, but gets students into independent/dependent/control variables, measurement, uncertainties, anomalies…the lot. Shamelessly based on an idea from the Physics teaching Podcast at https://twitter.com/physicstp
Calculating kiloWatt-hours lesson

Calculating kiloWatt-hours lesson

(0)
This would take most of a lesson, or a whole lesson if you have a follow-up discussion and compare results. An A3 sheet with a picture of a house and activity instructions, page 2 is a selection of appliances for students to choose from and put in their house.
Electromagnetic spectrum overview lesson

Electromagnetic spectrum overview lesson

(0)
Book a computer room, give students this worksheet, send them to www.darvill.clara.net/emag and let the lesson run itself. A good follow-up is to assign a type of wave to each student pair, and give them the task of researching and making a presentation about it in more detail.

V-I characteristic of a lamp

(0)
To do this properly, students would need a whole lesson. The worksheet walks them through the procedure, gives instructions about plotting the graph and scaffolds the conclusion.
Half life lesson
andydarvillandydarvill

Half life lesson

(0)
This is pretty much an whole lesson, but you’ll need to insert your own half life calculations worksheet (I have one that I like, but i didn’t write it so can’t include it here). The lesson centres around eating chocolate M&Ms. Or Skittles if you prefer. The idea is to have something that gives you ‘heads’ or ‘tails’ when tipped out onto the desk. See www.darvill.clara.net/nucrad for more gcse radioactivity stuff.
A level Skills practical - mass of a metre ruler

A level Skills practical - mass of a metre ruler

(0)
A whole lesson to teach problem-solving, practical technique & data processing to new A-level students. You have a metre ruler. You have a 100g mass. Nothing else. Your mission is to determine the mass of the metre ruler. (Hint - principle of moments) The powerpoint walks the class through how to do it, how to get reliable results rather than just make one measurement and then claim that you’ve done it, how to use graphical techniques to get those reliable results, and how to calculate the uncertainties. Adapted from an idea I heard on https://twitter.com/physicstp You should subscribe and listen too!
Intro to the photoelectric effect

Intro to the photoelectric effect

(0)
A-level physics. The powerpoint scaffolds the lesson. You’ll need to do the demo with the various light sources, electroscope and 5kV power supply. It’ll be fine… The other powerpoint file is a printable worksheet that saves a lot of writing.
