Rosella’s mam Christine is a biochemist. She works in a lab that makes creams, gels and ointments. She came in with Emma’s mam (Selena) to do an experiment with our class.
When Christine makes the special medicines it is important that she keeps her workspace germ free because germs can make you ill. This means she must wear a special germ suit, mask, hairnet, goggles and boots. She also has to test the air, the tables and her hands for germs. To do this she uses a dish with special jelly called agar jelly. They test the surface with a swob and then put a sample on the jelly then they put it in an oven so the germs can grow.
Selena and Christine gave us all agar jelly plates and everyone decided what they wanted to test. We swobbed teacher’s laptop, our tables, the taps, the door handles and even our hands. We put each sample into the agar dishes and Christine took them to her lab to grow them. We got to dress up in the germ suits too. We had so much fun. We can’t wait to see our results!!!
Thanks Christine and Selena
We had great fun dressing up as biochemists!!!!!
