Usually getting 2 groups in your class to achieve 21% is not something to be smiling from within about. There was a small whoop within today when 2 groups got the O2 percentage to be 21% in a recent experiment.
I do not doubt there were experimental imperfections but all in all to get that result was a delight.
Applied maths going good oh on the Projectiles, finished Resistance with 6 physics, 1st years are ALL up to date with their experiment books, although some are not using the graph pages for Diagrams :(
