This morning, Dr Margaret Ritchie enthralled us all with stories about her career and international research work. She then trained us in the use of pipettes and test tubes so that we can carry out some forensic tests on foods and drinks later in the term. We measured out 20 droplet of dyed water and compared with our team mates to see if we had been accurate and precise. (20 droplets should be exactly 1.0cm3) The session ended with a quickfire quiz – some winning team members are pictured.
Dr Ritchie explained why hydrogen and oxygen are unique in the universe – can your P6/7 daughter/son remember why?

Grace found this really interesting and was keen to tell me all about it.
