Not a prob mate. I spend literally hours on there (oh yeh I don't have a life!!! lol) But you can jump from applied chemistry to physics to astrology. If you need any help with homework they are willing to help. But I just love reading some of the replies to posts too, they are real characters. See ...

Thanks Robb, I will pass on these ideas to the teachers. I found another great experiment regarding foods and digestions, and that is to find out how much fortified iron is in cereals. Place the cereal into a beaker and add water and using a white magnetic stirrer after a few minutes or so you can s...

White Boards
Hi all, Has anybody ever had to re-coat any of your whiteboards? The trouble is over the years the film has come off and everytime any of the teachers write on them they have to use the special whiteboard cleaner spray to remove the text. Just wondering if anyone knows of the approximate cost too. T...

Hi everyone, While we are on the subject of Thermometers, a teacher found that some of our thermometers are reading 115c while boiling water. :-o :oops: Not sure if it's worth callibrating them using glycerol? But also isn't that just for when the liquid seperates inside???? Any input appreciated Julz

Toluidene Stain
Morning/Afternoon peoples, I would appreciate some info about the stain, Toluidene. I know it's used for showing the different structures and cells in say celery, but can it be substituted for another stain (apart from iodine)? I don't have any Toluidene on hand and it's not worth buying it in for o...

Hi everyone, Trying to get back in the swing of things but it is hard. Along the same lines as mummified cats and that, I have a real skeleton that needs to be put to rest somewhere.... Giving it a burial is out of the question, the police don't see the humour in digging up skeletons. :giggle: I bel...

Chewing gum
Hello everyone
I need help please regarding the affects HCL has on chewing gum.
Apart from visualling seeing what happens, what other test can be carried out? I thought maybe weighing it before and after but I'm not sure.
Thanks
Julz

Chemtalk is also a great way for us WA'ers to get in touch with each other, as we are not only isolated in areas but segregatated into Public and Private schools which is a shame. We have different PD days so there is hardly any contact between us. Be nice if there could be one day at the end of the...

70% Sulfuric Acid
Hi everyone, I'm in a bit confused, I'm setting up a prac that requires 70% sulfuric acid. It's for breaking cell walls of foods, fresh and processed. (upper school) The trouble is the science staff are divided as to what molarity it should be. I've made it around 7M which I think is strong enough, ...
