OCR science plus coursework

This half term we have been doing coursework. The experiment that was chosen was adding an indigestion tablet to acid and counting the bubbles that were produced.

Difficulties included – no decent response with 0.5M acid, but far too many bubbles with 1M.
– students couldn’t count the bubbles fast enough, even over 15 sec. In some cases they couldn’t count high enough!
