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.

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.

3D addons to science equipment
Just printed some 3D printed addons for the smartcart from . The reflective block is a bit too loose so we are working on a wider one to publish with a screw fixing.
