If in doubt, make your own calculations using the molecular weight of the chemical. I have to rush off to a meeting now but I'm sure someone else can explain. Once you do this, you'll wonder why you ever had to look it up! :thumbup: Yes i know how to do this but even these are different on differen...

OK i am doing up a new information booklet for the common chemicals i use at school. This is just for myself for making up solutions of my common chemcials. So many sites have different information on them for the strength of chemicals. What is the best site to get accurate information. Even between...

I absolutely love mine. My whole chemical store room in made of Gratnell shelving and drawers. So easy to adjust height with different size containers. So good for dropper bottles and solutions.
Ill add some photos after.

yes when i read it i thought, wow what a great idea.

i know this is a old old post but i have just came across a great idea of how to prepare the squares for the diffusion experiment.
K mart have silicone ice-cube molds that are perfect for the 3cm square cubes then students can cut another one down to get a 2cm square and 1cm square.

This is also a way that you can do the diffusion Agar 1. Measure out 1.6 g of agar-agar and 200 ml water. Mix them together with a whisk or fork in a large microwave-safe bowl. 2. Heat the solution in the microwave on high for 30 seconds. Remove to a heat-safe surface using a hot pad or oven mitts, ...

We use a mixture of both glass and plastic dropper bottles. The only chemical that is a must for me with the amber glass bottles is Silver Nitrate and Iodine Solutions. '
I have got my plastic bottles from both MTA and Westlab.

maybe it is Iodine (Potassium Iodide)

Fake Blood Recipe

175 g Cornflour
75 ml Water
175 ml Golden Syrup
Red food colouring
Green food colouring

Mix cornflour and water
Add golden syrup
Add the red and green food colouring (you will need to play around with quantities or these until you get the desired colour).

My question to that Kimmy is, has anyone been able to source the decanoic acid? I'm either having a bad senior moment or I am just useless, but none of my regular suppliers have this... :crazy: :crazy: :crazy: Mine is older stock but still fine to use. I think it came from either Chem Supply or Ser...

Our Senior chemistry are doing the Preparing artificial fragrances and flavours experiment.
Has anyone made the salicylic acid or the decanoic acid stock solution.

Any recipes would be great - thanks in advance.

i go under so many different name but basically as far as i am concerned i am simple the Science Assistant. On all paper work to do with the school i am a SAO (School admin Assistant). Some days when making up electrical wires etc i feel like i am a electrician, than the next day making Agar Plates ...

Never heard of a Dissection Policy?
Have any other schools got one of these?

Have learnt so much from all the wonderful members.

Happy Anniversary to me today.

Thanks for all the advice and great quick tips that we have all shared over the years.

I am not sure where i got this from, or who sent it to me but it is great. :clap3: Iv added a few of the suppliers we use here to the list also. It is just a simple spreadsheet with names of suppliers and what they sell and contact details. Thank you who ever gave me the original of this, but i just...

Endoterm reaction using citric acid, Acid base indicator using red cabbage, spaghetti, bicarbonate & lemon, bouncing ball using raw egg & vinegar, etc most of our kids would not have this stuff at home and we are trying to work on some simple experiments that kids will have the stuff at hom...

Now most of us are down to only a few students turning up at actual school and google classrooms now is what seems to be happening. We had our video link up science meeting this morning and i mentioned we need to actually get the kids off the computer for a bit. All lessons are basically now compute...

I have just looked at this site and the banned chemical list that is there, and if you go to the bottom of that list (after Z) it says the list was last updated 0n the 19/2/2020. So I don't think it is dark ages stuff. Thanks for the link Mel. It will be quite useful. I've already put it on my favo...

Hi Kimmy, Try this link: https://education.nsw.gov.au/asset-management/chemicals/appendices-to-volume-2/appendix-h-chemicals-which-are-banned-from-government-schools Sorry anyone not in a DoE school, the list is way too long to paste here... Hope it helps, Mel Thank you, that is the one I have but ...
