The Physics Teaching Podcast

Space is a challenging subject to teach, so a good subject for the first “Ways to Teach…” of this academic year. Thomas and Robin start with a look at some physics in the news. The proton is smaller than we thought! About 5% smaller which will make it even harder to find one if you lose it, but let's not be negative… In other news, a new wonder-polymer promises transparency, strength and lightness all in one. Will it be as successful as graphene (which Robin made the mistake of questioning in front of an engineer). And so to space. If there's one message (and thanks to Dr David Boyce and others for this advice) try to use models, demos and activity to show what's going on. It's tempting to think you can't do anything other than PowerPoint and YouTube for this topic, but whilst the odd video of cosmic phenomena can be great, you can make this subject live in the classroom. So whether it's “phases of the egg” or redshift on a balloon, try to get students involved in the subject. Living orreries, using beachballs to represent the sun and modelling the solar system's scale with a beachball and a pea – all this and more is in our first “Ways to Teach…” of 2022.

Thomas and Robin return after an extended break to talk A-level expectations, girls in physics and strategies for inclusion.

New year, new groups and tips to get underway. All this and an interview with the force of nature that is Professor Averil MacDonald. It can only be a brand new season of TPTP.

Well, we made it. What. A. Year. Robin and Thomas hook up with Patrick Kaplo to hear about how he has been getting on in the North Eastern USA and, as usual, get somewhat distracted. Thomas nobly tries to steer the whimsical chat towards physics teaching with limited success. Patrick had to cancel his extraordinary trebuchet competition because of the pandemic (see video below) and has also been suffering under incredible heat. This leads to him crushing another of Thomas' stereotypes about the USA and for Thomas to explain how he used his Physics teaching knowledge to save some money by investing in an inverter. Thomas thanks David Cotton (@newmanphysics on twitter) for a gift he sent of a vintage textbook of practicals and a tiny triple LED light demonstrator. We drift in to chatting about how relevant our Physics specs are to everyday life. Thomas asserts that he only used his knowledge of a vernier scale but Patrick quicly points out all the other ways. Robin is adamant (look away now CLEAPPS) that a basic knowledge of electricity is enough to do DIY electricity*. We then talk about the difficult year and Thomas reflects on his failures with Year 7 - making the same mistakes he made in his first years of teaching. We talk about what we are going to take forward from the pandemic and really hope that CPD will be better! No more drawing a "perfect teacher" or "perfect student"... Patrick and Robin both have a new start next year and Thomas is expecting a huge uptick in students at A-Level. We talk through the changes we'll face. If you teach a huge class of A-Level students PLEASE get in touch and come on the podcast to tell us your strategies. Patrick has itchy feet and wants to avoid James de Winter's "velvet lined rut". Finally some thank yous. Thank you to everyone who has listened, we couldn't do it without your support and kind words. Thank you to all the guests; so many wonderful people who have freely given their time. Thank you to Robin for being the brains of the operation, bringing some credibility and always doing the show notes (and nearly always on time). This is my least favourite task but I have muddled through ~ Thomas +And thank you Thomas for all the heavy lifting ~ Robin

Thomas has received a shiny new Travelling Microscope with a 0.01 mm precision vernier scale. There is only one thing he wants to talk about. First Thomas talks briefly avbout his 205 mile (329km) ride for Education Support (the only UK charity dedicated to the mental health and wellbeing of education staff in schools, colleges and universities). He's raised over £1,300 so far, and the donation page is still open. We then thank Tim Browett for getting in touch. Tim is going to be our guest for Ways to teach... Space, so if you have any ideas please share them with us in the usual ways (@physicstp on twitter and a contact form on the web site). Then on to the vernier scale, which was invented in 1631 by Pierre Vernier and is a simple way of taking high precision measurements. Thomas describes how he introduces it in class by making a large 1 cm scale vernier that can measure mm. This was the way Thomas taught himself to use it when he was doing A-Level and he thinks nothing beats the experience of working it out with a large scale where you can see things happening in front of you.

100 official episodes! Who would have expected it? We hook up on a beautiful day in Essex to talk about why we love Physics and go off on a series of tangents.

The aim is to talk through ones people suggest that are actually usable in lessons. As usual we get excited and make a few mistakes. Thomas is pretty sure that aeroplanes are made of aluminium, not steel and there were a few mentioned (Ant Man, Hulk) that we forgot to cover.

Thomas and Robin are joined by Paul Cook, senior lead technician at Ark Burlington Danes Academy and lead technician for the Ark Academy network. Paul gives us his top tips on how to get the most out of your relationship with your technician.

A short chat about teaching light with simple tools like light boxes (shoe boxes with a colour filter), lenses and mirrors.

Thomas and Robin discuss a few strategies you might use to help you assess your exam groups in physics, as well as grappling with pervasive mass-weight confusion.

Thomas was interested in how the brain makes its own beat, and put together this little sound test. You'll need headphones to appreciate it properly, but it is interesting to listen to on speakers as well.

Loosely focused on KS3 (but when have we ever stuck to the brief), this episode looks at ways to teach sound with David Cotton, the most enthusiastic proponent of the topic.

We are delighted to be joined by Mark Robinson (@mark_robo) who has had some deep thoughts about how to write and mark questions. So much so that he has taught a computer to do it for him and you can use it too!

We are delighted to be joined by the inspirational David Cotton to talk about supporting trainees who have missed out so much during the pandemic.

Thomas and Robin are joined by Patrick Kaplo from Wyndham, New Hampshire to follow up on a question he asked way back at the beginning of the Covid crisis, namely "How will this change our practice?"

We are delighted to be joined once more by Friend of the Podcast and Physics Teacher Support Polymath Carole Kenrick (@HelpfulScience) to talk about Literacy for Physics.

We are so privileged this week to be joined by Christina Astin. She wears so many hats she would keep a division of milliners employed, but she kindly talks us through some of her most recent and most important work.

Will introduces us to Nearpod which is a beautifully designed teaching aid that has lots of excellent features to help you with AFL during lockdown.

Thomas and Robin chew the fat over how they are progressing in the new lockdown.

Thomas and Robin return to talk survival as we lock down again. With many teachers now doing hybrid teaching, we discuss strategies for keeping sane.

We talk through the dear listener's favourite holiday season activities; things that make you smile then think.

Thomas and Robin have a couple of goes at sharing the ideas our dear listener has given us about teaching about magnetic fields and magnetism. We were particularly thinking about non-specialists who are likely to be covering this with the younger kids.

What are ranking questions and why do they matter? James de Winter pops by to tell us. What do we do about resource curation? Could you be the answer?

How great to reach out across the pond and catch up again with Patrick Kaplo (an early hero of the podcast who teaches in Windham, NH). He has been hunkering down and adapting to new paradigms, and it is refreshing to hear that the problems we are all dealing with are pretty similar, no matter where you are in the world.

Thomas and Robin meet outside, at an appropriate social distance, to remember Tim Hardingham and introduce an interview with the PhET Head of Development Ariel Paul (@DrArielPaul). Surely all physics teachers have heard of this outstanding free source of simulations and demos provided by the University of Colorado Boulder.

Robin and Thomas are joined by Rajani Nair (@NairPhysics), (who before answering our tweet had not heard of the podcast) and who shares her ideas about teaching Specific Heat Capacity at A-Level. She also has a wonderful memorable practical which involves throwing eggs. We are then joined by James de Winter in a (hopefully) regular slot "Dispatches with de Winter" where he talks about the book 5 Easy Lessons.

The Nobel Prize is still the ultimate accolade and viewed with envy by the fields that don't have a Nobel Prize (in your face, maths!). This week we start by congratulating the three winners of the 2020 physics prize: Roger Penrose, Reinhard Genzel, and Andrea Ghez, before talking to FoTP, Carole Kenrick about Domains and Zines.

Thank you so much for making such a great job of teaching with the Covid restrictions! Given the circumstances, schools have done an extraordinary job, and this episode shows how teachers will always find a silver lining. We get a raft of ideas from folk turning the situation to their advantage; for example using visualisers to zero in on the crucial points of practicals, using OneNote to 'write' equations for you... we could go on.

Way back at the beginning of series one we were thrilled to hear from an international school teacher named Matt who had just landed in Lima. Fast forward two years and we have finally managed to organise a chat with the fabulous Matt Bowman.

Season 3 continues to deliver physics royalty as James de Winter joins us. James is the physics tutor on the Cambridge PGCE course and has seen generations of physics teachers through their training. Having met a fair sample I can say that all of them hold James in the sort of reverence that Luke reserved for Obi Wan.

Robin and Thomas reflect on a first week back under the new covid guidelines and find time to talk through a simple required practical - timing a trolley rolling down a ramp.

Thomas and Robin look forward to a new - albeit different - school year with some reflections on "the new normal" and an interview with physics-teaching Royalty.

Thomas doesn't know which week it is; thinking there is one more week of term he drags Robin to his garage to test some vacuum cannon upgrades. Thomas and Robin also look backwards and forwards though the podcast's second season. A Tight Collar Thomas has been experimenting with the collars that are used to join vacuum cannon spec pipes. After initial excitement (described in the podcast) Thomas does some further testing (described in an addendum) and finds that they don't seal perfectly when pushed on dry and that the hole in the middle is slightly smaller than a table tenis ball (which probably doesn't matter). The collars can be cut in to slices to make round flanges with three benefits: - Greater surface area for the tape to grip - The potential for “reloading” the tape off-line whilst another shot is prepared (one of the issues with the cannon is the pfaff of taping it up in the lesson - Easier reloading when you forget the ball! The slices can also be used as a mechanical support for the “gold standard” flange – if you have managed to persuade tech. to make you them. Thank you. It's Been… Emotional There are so many people to thank. We would not do this without *you* dear listener. The emails we get cheer us up and keep us going. We have had so many guests; thank you to you for giving up your time and being so flexible. (Special mention here to Miss Neutrino who happily rerecorded the podcast after Thomas didn't press the right button). Thanks to Patrick Kaplo, who has become a good friend and who we were very disappointed not to meet face to face this Spring. Finally, thanks to our families, who think we are bonkers but wave us off to our respective cupboard and garage each week.

What will the well-dressed physics lab be wearing this year? Jonathan Shaw secured £53,000 of funding to kit out his physics department and asked Thomas and Robin to throw this over to the physics-teaching hive mind, and you did not disappoint! We had some fantastic suggestions, and some surprises.

Peter is one of those special people who is a finisher. Dissatisfied with the resources available to him in his trainee year, Peter set about creating his own resources. Not only that, he shared them through his web site, sciencedoctor.school.blog. His one problem with all this #sharingiscaring? The endless requests for the answers. If you use the resources and there are no answers, then please send them to him. Thomas says he will put a link to Peter's site on the resources aggregator we host, https://resources.physicsteachingpodcast.com. Peter also suggests ways of spending Jonathan Shaw's £50,000 on Physics equipment - his ideal would be to spend £10,000 on one big ticket item. Thomas is skeptical, Robin delighted. Finally, Peter's Practical in Memoriam is a beautiful way of making one of the less inspiring practicals (density) more appealing.

Rachel tells us what she's learned about getting yourself online. Empowering stuff and some great advice from Rachel about how to make a resource that will be of lasting value in your classroom.

Jo is a career-changer from a medical background who kindly agreed to join us to chat about her experience of teaching physics.

Friend of the podcast Dave Farmer returns to talk about a subject to strike fear into any physics teacher's heart: uncertainty! We peel away some layers of complexity to reveal... more layers of complexity! Having worked with a lot of exam boards' A-level specs over the last few years, Dave recommends reading the mark schemes and looking for examples of what your particular exam board recommends. Whether we are talking scale resolution, combining uncertainties or ascertaining the gradient of a graph with error bars, we couldn't agree on any of them. But don't despair, there's a lot of uncertainty about uncertainty, so just work out what your exam board require and after that, let your students develop their ideas. We also emphasise that all of these methods are estimations and approximations: rigorous statistical consideration of uncertainty is a scientific career in itself, so inevitably A-level is just going to scratch the surface. Finally we celebrate a physics teaching hero: take a bow Dr Peter Edmunds the Science Doctor who has shared an immense catalogue of resource for physics at all stages. Stuck for some resources? You'll find something on Peter's excellent site - link below. Why not fill your boots and then buy Pete a coffee?

Wall-to-wall gimmicky demos on this week's podcast as we welcome John Hudson. Although we call them gimmicky, nothing could be farther from the truth: John introduces us to some great experiments and demos that are crammed full of physics to inspire and talk about.

What can we usefully get students doing at home to explore their physics and what (cheap) kit might we be able to provide them with come September?

We are delighted to talk to Mark Whalley, IOP Education Manager, former headteacher, and of course, a physics teacher. Robin caught up with him to chat about KEEP Teaching, a project funded by the EEF, run by the IOP, and evaluated by UCL that is looking to find out what will keep early-career physics teachers in the classroom.

The "new normal" has once again shrunk the globe, as Thomas and Robin reach out to Alberta, Canada to talk to the inspirational Laura Pankratz of the Perimeter Institute. Just as well we talked to her when we did because apparently we've discovered a black hole next door...

The "new normal" is just another way of saying "weird" as far as we're concerned. In this episode, we range around the emergency assessment routines that OFQUAL have put into place, reflecting on the humanity and fairness that they have managed to salvage from what is a stressful and potentially difficult end to our GCSE and A-level students' studies. It is interesting to contrast with CPAC, as this time of year also sees us tidying up and finishing of this traditional aspect of A-level assessment. Thomas talks about his experience as an exam board moderator, and we discuss whether this model of accountability has somehow lost its way.

Alexia has a Physics degree from Imperial (which made Robin happy) and a PGCE from the London Institute of Education (which made Thomas happy). She has many strings to her bow. In addition to being a physics teacher, Alexia is a LaTeX guru, has a fascinaton with neutrinos and tweets as @MissNeutrino. Alexia tells us about her NQT year and how she is faring in her first year as a Teacher.

Thomas and Robin have heard some strange tales of what is going on in different schools. Virtual learning walks sounds like unnecessary stress at this strange time and what about detentions for the kids if they don't turn up on-line? They have had some success with Teams and discuss how they are trying to set work for the children that is practical rather than more worksheets. Thomas is missing equipment for teaching and Robin is missing his colleagues. On we go in this strange time...

Patrick, Thomas and Robin try out zoom. Patrick tells us hhis successes and failures and gives Thomas the top tip of zoom breakout rooms. Thomas is clueless about what to do with Year 7 and asks for advice. Thomas then chats with Emma Brown in Shanghai who has to teach classes of 70+ online. She has some good advice about using video and ways of checking the kids are engaged. Finally Thomas and Robin report back about how they got on and Thomas gives an update on his collaboration with Helen Reynolds making a resource site for Physics teachers.

So much has happened in such a short time, Thomas and Robin decide to talk to some experts about how to support their students remotely. YouTube is a great resource, but also Physics teachers all over the World are cooperating and sharing. The podcast scrapes the surface of this but we get some good advice along the way.

Fabio Di Salvo joins us to talk about Chat Physics, Physics chat on Twitter. Robin asks for advice about the photoelectric effect.
