Added another nice rainbow photo to my collection yesterday when the low evening sun combined with a sudden rain shower.

I extended GUESS to GUESS SUn adding Significant figures and Units at the end.

Madeira is lovely too but does it have a sea pool fed by a natural thermal spring where you can float in bath temperature warm water watching shoals of fish swimming amongst the bubbles rising from vents? And if you force your teenagers to get up v early you can have it to yourself?

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.

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.

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.

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?

Interesting when you add an Earthed copper wire in the centre.

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.

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:

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.

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.

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.

@crossjack.bsky.social It is now definitely readable (I only had a finer grade wire wool in the house). Should I do more - i was worried I would damage the scale markings. Is any wax wood polish okay or specifically renaissance wax? I think it doesn’t look too bad for 30 Pounds + postage.

@crossjack.bsky.social I bought a cheap travelling microscope from eBay. Any tips for best method of removing surface rust from the scales?

@crossjack.bsky.social any idea on the age of this microwave transmitter
