Re: Limit on number of Practicals done each week?
Hi Sarah, Do please read the thread Urgent help needed. How many teachers do you have? also how many students? Do the teachers help them shelves to equipment, or is it locked away.

Re: Iron Sulfate
Disposal Retain for collection by a waste service or <100 g/day may be dissolved in 20 times the mass of water and poured down the drain in a stream of water. Do remember most of you have pit or Sump of some sort, hence the CSIS lets you put it down the sink to waste, with lots of water of course.

Re: Wheatstone bridge
The Wheatstone bridge is an electrical bridge circuit used to measure resistance. It consists of a common source of electrical current (such as a battery) and a galvanometer or a multimeter that connects two parallel branches, containing four resistors, three of which are known.

Re: Ammonium Iron Sulphate
Your SDS should tell you. But it needs to go to chemical waste collection. In a jar or container well labeled.

Re: Risk Assessment
Hi Kimmy68 I do not think there is any thing on that, I would be very interested if there is. The DoE put out the CSIS and the teachers should do a RA in there head. I agree with new teachers we need something.
