Fun Physics
Physics can be quite fun and amusing at times. A glass of water, a piece of paper, and a bowl ready for when things go awry. #ScienceFun #PhysicsExperiment

Simple Harmonic Motion
With a @pascoscientific Force Sensor at the top of a spring and an Ultrasonic Motion sensor at the bottom, the phase relationship between force, distance, velocity and acceleration can be examined and taught online within minutes.

Mitosis
Slide making and staining and then trying to look for mitosis happening. Trying to find the different stages of mitosis is quite tricky at this magnification. This was one of the best slides.

How useful is the CG50 Geometry
Just how useful is the Geometry App in the CG50? It seems to be quite good for GCSE Maths but I am not really sure it is worth the effort for A-Level Maths. Sure it can do some clever things, but the interface is hard to use so no marks here.

Learning to test Chemicals
One of my favourites - identifying the unknown chemical. First flame tests, then chemical tests to determine the unknown. The Silver Nitrate test came out particularly well. I sometimes can't tell the Bromide from the Iodide, but in this case, I could.

Input / Output devices
Input / Output devices - easy in A-level computer science until questions like this come along, then it gets more fun. What specialized input and output devices are used in fields such as medicine and engineering?
Using a spectroscope to look at Helium
Using a @pascoscientific spectroscope to look at the discharge of Helium. After using a hand held spectroscope I now know what the students are looking at. #ScienceTeacher #Spectroscopy #STEMEducation
