Creating a resonance driver. The speaker has its note changed. This pulls on the cord which is attached to a spring with a weight. At the right note the spring starts to vibrate wildly.- the resonance frequency #iteachphysics #physics

Going Green
New video Podcast on Going Green Starting on Earth Day we celebrate your conscious decision to make a better world.
Old tech ticker tape timer and a Pasco Dynamics Cart
#iteachphysics old tech. A ticker tape timer and a @pascoscientific dynamics trolley producing great ticker tape graphs to stick in a students book. Although I have the new technology you can't beat this way of really getting to grips with acceleration.

Earthday 2021
A very easy thing to do on #EarthDay2021 plant some wild flowers. Help restore the natural flora and help the insects as well.

Earth Day 22nd April Looking at alternative energy and finite resources
With #EarthDay2021 a couple of days away, I have been looking at renewable energy and the finite resources the Earth has left with some of my students.
The students coming to my home are still surprised to see solar panels on the roof - are they any good, do they save any money.
They all still need to have the latest phone and won't recycle the old one. They use more and more energy and although they worry about climate change it's up to someone else to do something.

Friction and Forces
#GCSE #Physics Looking at forces. A box is filled with some mass to make it heavy and then pulled across a surface. What happens if we put more elastic bands on, does it get easier or harder to pull. What happens if we spill oil or water on the table does it get easier to pull? #iteachphysics

New Tension Protractors
Two @pascoscientific tension protractors arrived today from @SciChemEdu I was a little surprised when they came unexpectedly. Been trying them out. Hopefully this will make forces and moments easier for my students to visualise and understand. #iteachphysics
