Parallel Springs

 All the students know about Hookes Law and weights on a spring, but much weirder things happen when there are springs in parallel. It is down to the A level students to work this out.

 Isn't it easy to show velocity Force and Acceleration using a @pascoscientific smartcart, from @SciChemEdu and a vector display. I didn't need all the kit out and after a few minutes the students remembered the experiments to tell me about them. #iteachphysics

 Starting to print on the 3D printer some @pascoscientific diy metre stick torque set. I have ordered a Pasco one through @SciChemEdu with an Aluminium metre rule but I thought I would try out the wooden ruler version.

This is ideal for working out moments and is extremely accurate and very sensitive. Instead of the fulcrum that was designed I am using a modified file so that we can use the rotary motion sensor.

 

Using @pascoscientific dynamics trolley and an ultrasonic sensor supplied by @SciChemEdu to carry of some Physics Revision. Using these today just as models to remind the students of the experiments they have done.#iteachphysics

3D addons to science equipment

 Just printed some 3D printed addons for the

@pascoscientific

smartcart from

@SciChemEdu

. The reflective block is a bit too loose so we are working on a wider one to publish with a screw fixing.

The rotating block for the smart cart fan looks to be a useful addon.

Back to Practicals

 So glad to be back teaching the students face to face and getting back to letting them do the practical work. Starting today with titrations.

Teltron Tube

 I have been doing a lot of work recently with students doing A level Physics looking at the discovery of the electron and how electrons and behave in a magnetic field. This teltron tube is set up with Helmholtz coils to do just that.On the left a low voltage supply heats a wire so electrons are given off, and then on the right a high voltage supply attracts the electrons and fires them across the tube as a beam of electrons.
