Old and New Technology

 Using old and new technology together, with a tickertape recording and the @pascoscoientific smart cart generating a realistic record of the journey down the track

Shapes of molecules across a period

Looking at the shapes of molecules changing as we move across a period. Fun naming some of the shapes and working out the angles, then comparing Methane, Ammonia and Water and why the angles change
 

Respirometer

 Investigating respiration using the respirometer to measure the uptake of oxygen from some germinating cress seeds. Its going to take a while so the next candidate for a time lapse

Reversible reactions

 Take blue hydrated copper sulfate heat it to make white anhydrous copper sulfate. Add a little water observe the colour change and the het given out. Heat the blue copper sulfate and return to anhydrous copper sulfate and repeat. Some repeated it four time and were convinced it could go on for ever.

A Level Computing

 

A level Computing and I got out the #turingtumbles. I don't think I have ever seen the students so engaged. The lesson ended and they all stayed on solving problems of logic

More Spectral line

 Using the @pascoscientific spectrometer to show the same spectral lines as the simple spectrometer. the students were more convinced that the spectrometer was showing the right thing. Much easier to use and see what is going on

Spectral Lines

Using a very cheap and simple spectroscope the students with the help of the camera could observe and record the spectral emission lines from different sources
