Bits and Bobs
Robin asks Thomas what the bits and bobs were he sent home to his A-Level students. What would you send? Tell us by tweeting @physictp #tptpbitsandbobs
Thanks to Frank Noschese for pointing us at the “String and Sticky Tape Physics” PDFs: http://www.arvindguptatoys.com/arvindgupta/edge-one.pdf and http://www.arvindguptatoys.com/arvindgupta/edge-two.pdf .
We also mentioned Laura Pankratz’s speed of sound measurements with a bottle. There are similar experiments here https://www.thenakedscientists.com/get-naked/experiments/blowing-bottles and here https://www.physicslessons.com/xlab-speedsound.html If anyone can find a good set of instructions for how to do the measurements with home kit (and video it pleeease ) then we would love to promote it!
Also, we couldn’t find the experiment Thomas refers to where you tie weights together so that they pull the next one off a drop and end up with string spacing such that the sounds of the weights hitting the floor are regular. If you can come up with a good story as to how this might work at home, let us know!
Please share ideas or successes – or indeed questions – on our Facebook Page: https://fb.me/physicstp . You can also message us via our website contact form at the.physicsteachingpodcast.com, Twitter @physicstp, email using the address given in the podcast (if we remember), you could even email us an autio file if you are feeling really keen.
