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.
Microscope servicing: Can any one recommend a microscope servicing company/person who would do the Gold Coast area please?
Calcium Carbide: My teachers are wondering whether there are any restrictions on us storing and using Calcium carbide for pracs here at school?
Mitosis in onion root tip: Are there alternative stains for mitosis in root tips please? It needs to be inexpensive (I've been quoted $150 for 5 gm orcein, including postage), not too hazardous,
Employment: Are there any standards or recommendations regarding the number of hours a lab technician should be employed?
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).

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.
The Chemical Management Handbook was developed by Science ASSIST in recognition of a need for guidance on the safe handling, storage and waste disposal of chemicals in schools.
In this investigation, students explore the properties of gases and liquids. They will follow instructions to predict the effect of changing a variable when planning an investigation.
