Chemical waste and septic systems: I have been working in the education department for the last eight years, and have recently started working one day a week in a small school.
Use of Science ASSIST resources: Do I need permission to use and/or adapt the resources on the Science ASSIST website?
Radioactive Minerals: Our school recently found a cardboard box of radioactive minerals which have been stored at the back of the cupboard.
Plasma ball: Are there any safety issues associated with using a plasma ball in the classroom? Sources on the internet seems to give conflicting information and I would appreciate some clarity.
Agar plate storage in the fridge: Is it necessary to store the agar plates upside down in the fridge?
Legalities of practical work: While I know it is not ideal, is it illegal for a science class to undertake a practical if the regular classroom science teacher is absent?
Phenanthroline: My Chemistry teacher would like to use Phenanthroline for senior chemistry EEI’s. The MSDS lists this chemical as Acute hazard category 1, and Acute toxicity oral category 3.
Autoclaving microbiological waste: we have just purchased an autoclave, however it has minimal instructions and no preprogrammed settings.
Food tests: glucose, starch and gelatine solutions: I have to make up solutions for a prac where students are working out if select foods are a protein, carbohydrate or sugar.
Food testing is routinely carried out in senior biology classes. Students test a variety of food samples for carbohydrates, such as sugar and starch, lipids, proteins and vitamin C.
