New Spectometer form Pasco

 @pascoscientific just announced their new UV-vis spectrometer. I am still a bit behind with my wired colorimeter supplied by @SciChemEdu a few years ago. Works well and does great expts. Looks like I will need to save up some more pennies.

I find that for many of these new toys and inventions altjhough the students use them a bit, I get more out of them than the students. 

Diffraction Grating

 #alevel #Physics revision Looking at a laser passing through a diffraction grating to determine the wavelength of the laser light. Measuring the angles between the dots, gives an accurate measurement of the wavelength. #iteachphysics

Pinhole Camera

 The bright sunshine is an excellent opportunity to try out the pinhole camera. Many students are amazed to see images with such a simple device. Many thought photographs could only be taken an a several hundred pound smart phone. #iteachphysics

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
