The teachers here like to use Sulfuric Acid of course with distilled water. Perhaps their judgement of how much Conc sulfuric acid they put in is the problem??

We have used a Voltameter with of course Sulfuric Acid Conc, we have new plugs at the bottom. It took a long time for it to bubble this time around, although the plugs do not fit too well, just a little lose, (Sulfuric acid drips out). Could our Sulfuric acid be too old, it was purchased in 1997, ha...

Sorry

Thank you Robb, I shall do that. MSDS do not have all the information one can need. So just ask Robb

Hi Pat,

Any chance of a photo of your two kids??

We have a outcome test, where the students heat up a test tube with Zinc oxide inside it. The students do not know it is zinc oxide, just marked as A . Can this zinc oxide be used again, for the same test. As I am sure their is no change with heating zinc oxide, the B test tube has copper carbonate,...

Hi Folks,
Welcome to so many of us. Robb is that date correct Nov 26 1965. One of our students have asked, or is it just out of date?????

I would not get Carton Stero Microscope's, put out by Science World P/L They have a plastic case around the objectives, it is this plastic case, that brakes so often. It is not very strong, and cracks, over time we have replaced these case's. You can only turn the objectives via the case. That is th...

Lets hope they do not use the soap, which used 6M, heavens help.

Thank you so much folks. We are going to purchase the CD's, I put all the information down from chemtalk, and the board deceided it was a OH&S issues, so it should arrive next term.

Thank you again

Hi folks, I have received more information from chemwatch, the training is quite a price. Was it easy to pick up using the CD's Did you have training on the CD's Is their written instructions on how to use the CD's Perhaps you wonderful people that paid for chemwatch, could answer the above questions.

Every thing that goes into a class room must be labeled. Even if it is unknown, must have a coloured dot. In some out come tests, we have little dropper bottles marked with a green dot, and unknown. I can not find it at the moment, but I do believe you can only have 250ml of unknown in the class at ...

We have been in touch with Chemwatch, and I received some information to day. A 6 page brochure, cost about $80.00 + GST each year. My head teacher will read through the brochure, and guess make up his mind. Its the disc's, you people have been so very helpful, indeed. When some thing is strange, it...

Great idea Rob, thanks we will try that next time.

He really is very good, he did two very old Electronic balances for us. It was given to the school in 1961 when it first opened. We did not think it was worth fixing. So Eddie took it away, and came back with a quote, Via the phone, and we went ahead. Its a big old thing, but being big and old it is...

Very very cute,

Thank you for all your help, in the end we spray river pebbles silver, so the students can not see the difference, between them, used river pebbles silver, zinc, and mg ribbon.

Thank you all so much

No I do not mark exams. I would help out, but if I ever need help with something, only the head teacher, seems to be the only one to help.

So I keep to my part.

Thank you Robb, I had not come across this before. The teacher had said he used it many many times before. But I do thank you for your time. It all makes sense now.
