Recommendations for microscope replacement: Our school microscopes are old and in need of replacement, however I am interested in viewpoints as to whether traditional compound microscopes are still
When choosing a microscope consideration needs to be given to the application, skill level of staff and students and budget.
Chemical Labels: How do I know if the chemical labels that I have been using are compliant?
Disposable nitrile gloves: How chemical-resistant are disposable nitrile gloves? Are they only resistant to certain classes of chemicals and up to certain concentrations?
DRONES: Everyone seems to be droning on about drones so which ones have people used??
Storage of offal: Is it acceptable to store offal, such as plucks, hearts, kidneys, etc., in a freezer for long periods (months) for future use?
Recommended Chemicals for secondary Schools: I have to order new chemicals for our school in QLD, but the following chemicals are not in the list "List_of_recommended_chemicals-18March-2016.
Safe concentration of HCl for Year 8 students to use?: A year 8 textbook has an activity which includes an example for a colour change (blue litmus paper with HCl added to it).
- Year 8 > Science Understanding > Chemical Sciences > Chemical change involves substances reacting to form new substances > ACSSU225
Balloons: I haven't heard of any issues but we have a parent who is concerned with regards to balloons and latex and the powder residue in them.
Safety issues are a significant consideration in the teaching of microbiology as the subject is practical-based and there is potential for exposure to infectious organisms.
