As tungsten halogen lamps give out some UV I wondered if I could use a vintage Rank Aldis Tutor 2 slide projector to show UV beyond the visible light in a spectrum #ITeachPhysics #SciTeachUK Two simple ways to reveal the UV beyond the violet end of the visible light specturm youtu.be/8lr-LA-0xzc

The breaking stress of a crunchie bar practical is a standard for my physics lessons during the materials topic so I made this video describing it. #ITeachPhysics #SciTeachUK youtu.be/Kr6YKfMN1f0

Making good use of the Radiacode 110 which they kindly sent me for using in my YouTube videos I made this video about radioactive things you can buy relatively cheaply. I hope you like it. #ITeachPhysics #SciTeachUK youtu.be/gdcyphtu26k

Radiacode kindly agreed to send me one of their gamma ray detectors (the Radiacode 110) so that I could see how it might be used in physics teaching. Here is the first video making a gamma ray spectrum from the school cobalt 60 source #ITeachPhysics #SciTeachUK youtu.be/DRDnrSdAKTs

Inspired by @harvard.edu natural sciences lecture demonstrations video which shows a projected absorption spectrum of sodium I created this version with an extension to then project the emission spectrum. I hope you like it. #ITeachPhysics #SciTeachUK youtu.be/Gz--LUuYvSg

This video is about how to use 4 way stretch cloth to model electric fields. It is based on an activity in the @perimeterinstitute.ca resources for teaching fields available from here: resources.perimeterinstitute.ca/products/fie... if you make a free account. youtu.be/ea6RB8nb6iU #ITeachPhysics

Used my ‘new’ 1960’s slide projector to make the best projected spectrum I have managed. I hope my students appreciated it. #ITeachPhysics #SciTeachUK

I made this compilation of some of my favourite demonstration videos from the last couple of years Which almost look like magic (to me at least). I hope you like it. #ITeachPhysics #SciTeachUK youtu.be/jQKr1ZrQSjc

I built a resistor cube to test the theoretical answer to the interesting extension question and filmed it with an infrared camera to show the current symmetry which is my favourite way to solve it. youtu.be/CQ5CAqUHHxc #ITeachPhysics #SciTeachUK

I made this video about the Photon Bricks Lego interferometer which UK schools can loan for free and they have instructions if you want to build your own (quite costly). Link to their site: artlab-nottingham.com/lego/ My A-Level students enjoyed it. #ITeachPhysics #SciTeachUK

I have made this video about electron diffraction which features what I think is a new demonstration which uses three crossed diffraction gratings, a violet laser and glow in the dark film to demonstrate and explain relatively simply why the electron diffraction produces rings at 3 mins 30.

There are some really good simulations and a simple video analysis tool on this site: #SciTeachUK #ITeachPhysics mintapps.org/html/mint-in...

What will happen to the balance reading when I drop a magnet through the copper pipe which is supported on a clamp stand on the zeroed balance? A predict and explain demonstration with electromagnetic induction, terminal velocity & Newton 3 #ITeachPhysics #SciTeachUK youtube.com/shorts/s0eOE...

Set up the pearls in the air demo today for projectile motion: #ITeachPhysics #SciTeachUK

Using a microammeter and low voltage power supply find the resistance of a person or even loop of people by measuring the potential difference across and current through them. It is a fun alternative to finding resistance of the usual components. #ITeachPhyiscs #SciTeachUK youtu.be/sDb9cUbs3gM

@lascells.bsky.social my monkey and hunter launcher was not hitting the switch when released earlier. The screw on the end of the spring bit seemed to not be pushing through. Any suggestions to fix? I have improvised a ripping Al foil method for my lesson tomorrow but hope to fix for next time.

After 20 years of teaching I finally built a working flame probe for measuring electric potential and used it with my students earlier in the week. It really is good for bringing alive the electric fields topic. I made this video about it: #SciTeachUK #ITeachPhysics youtu.be/f0YWO2PfBVU

Did this in my A-level lesson today which I think was interesting for the students. #IteachPhysics #SciTeachUK Measuring the capacitance of a parallel plate capacitor by discharging it through an oscilloscope youtu.be/-4JNebKmJEU

It was good to get A-level students doing some calculations with the shuttling ball demo yesterday: #SciTeachUK #ITeachPhysics youtu.be/usP5YtWQh6c

Set up this old Nuffield demonstration for the first time yesterday afternoon ready for my first A-Level lesson of the electric fields topic on Monday. Simple but effective I think. #SciTeachUK #ITeachPhysics Paper indicator to show the direction of a uniform electric field: youtu.be/oAVDkdi7nb8

I was trying to have a break from thinking about physics teaching in the Azores but this beach got in the way: youtu.be/lj-ZZTG0ddU #ITeachPhysics #SciTeachUK

Finished two days of loudspeaker making with year 8. Key to making them loud is to ensure the coil is securely attached to the cup so that the cup vibrates along with the coil. #ITeachPhysics #SciTeachUK

Got the few students who were actually in my lesson this afternoon to test out the tumble buggies / constant velocity buggies ready for next year. #ITeachPhysics #SciTeachUK One of the many activities in my forces and motion sets of ideas www.teachphysics.org/home/forces-...

Useful and inspiring day at the @ogdentrust.bsky.social senior teacher fellowship induction today in Stratford upon Avon. Found time for an early morning river walk. Looking forward to making more sets of physics teaching ideas next year. #SciTeachUK

Inspired by Arbor Scientific’s 10 ideas with a plasma globe I set out to see if you could verify V is proportional to 1/r. After failing because I used a metal clamp stand it then worked perfectly. Full details of the setup at the end of the video: youtu.be/crW7pMdZxUc #ITeachPhysics #SciTeachUK

The workshop includes lots of the ideas that I have developed as part of my @ogdentrust.bsky.social senior teacher fellowship in the last year.

Just finished planning my workshop of fun physics things for KS3/GCSE for the Bedford Festival of Science CPD event on 8th July. Booking link: www.eventbrite.co.uk/e/secondary-... It features this but do you know what it is? #SciTeachUK #ITeachPhysics

Inspired by a video made by James Lincoln about electric fields I have been exploring using copper mesh, a fun fly stick and threads to show electric fields ready for teaching in September. Photo attached and link to video if you are interested youtu.be/lD3V6-2WTAw #IteachPhysics #SciTeachUK

I struggle to get good results from our gas discharge tubes, EHT I tried the Arbor Scientific of using a plasma globe instead which works very well as you can see in the photo. Full details in the video: youtu.be/AjuKXOFSdjY #IteachPhysics #SciTeachUK

A great thank you present from some of my A-level students. As it doesn’t have a case you can see how it works: Floating magnet platform explained youtu.be/vmkKEfvzeFI #ITeachPhysics #SciTeachUK

This is probably my favourite idea on slide 140 from the waves collection of physics teaching ideas (see quoted post). Using a cheap remote controlled LED light to see the appearance change under red and green light. Students have to explain it. #SciTeachUK #ITeachPhysics

Magnetic field chips are a beautiful way to show magnetic fields in 3D and much less unpleasant than iron filings. You can buy them ready made or cut up freezer bag twist ties (suggested by @cleapss.bsky.social) or plastic covered garden wire. youtu.be/pPDsVYkGyM8 #ITeachPhysics #SciTeachUK

Apparently it is green turtle day which reminded me of my favourite wildlife encounter- independent snorkelling in Cyprus with my family and seeing these beautiful creatures last October.

I made this google slides of nearly 100 ideas for teaching magnetism and electromagnetism in the Summer term with help from @hookean.bsky.social If you haven’t seen it then it is worth a look: www.teachphysics.org/home/magneti...

If the waves set of teaching ideas makes you want more of the same then a reminder that this is the forces and motion set that I shared in January. #ITeachPhysics #SciTeachUK

Here is the collection of over 250 ideas for teaching the waves topic from KS3 to A-Level. Follow the link to access them all: www.teachphysics.org/home/waves-i... Thanks to all who contributed and especially @ogdentrust.bsky.social for funding my time to make it. #ITeachPhysics #SciTeachUK
