Hi Sunray,
Where did you end up getting your pipette fillers from? (the ones that worked!)

Re: Chart storage
Thanks for the suggestions. I like the idea of the Wallfile, and will suggest this for the new storage area.

Chart storage
Hi gang,
How do people store their charts? Ours are rolled up and sit on top of a flammable storage cupboard!

Re: Pipette Fillers
Ordered some pipette fillers from Office max recently, the ones with the adjustable thumb wheel, and half of them are too stiff to turn the wheel, so they've been forced and the plunger thing inside has come away (broken). Is it worthwhile ordering from somewhere else, or is this problem a sign of t...

Hi Smiley, We just had a go using scotch fingers and adora cream wafers. What biscuits did you use? Also, I used ready bought frosting as it was a small class, but now some more people want to do it, and I'm thinking I'll have to make huge amounts of frosting!!?? But all up a huge hit, and once more...

Hi Kathryn,
I can remember doing this years ago using Elodea. I have some if you need it.

Hi Rosalie,
Are there still many vacancies for workshops? I wont get an application in until next term.

Re: Acidified Barium Nitrate
We use 5% Barium Chloride and drops of conc HCl.
Just a further note to this , we used a method this year that added agar as a coagulant (I think I got the method from Chemtalk), and the results were really good.

Small Goggles
Hi all in labbie land, I've had a look through most of the catalogues I have, and can't find anything on small goggles. We are always needing the odd pair for the odd small head that turns up. I've tried the 'rubber bands around the end' trick, but on some kids it's not successful. Any help would be...

Hi gang in lab land,
I am trying to make those heat conduction metal rod things with globs of wax on them, and can't get the wax to stay on the rods!!! Is there a trick to this?
Needed by last lesson today!!
Grateful for any help.

Re: Ammonium nitrate
Hi Lada,
Yes, endothermic. I have found these alternatives in case anyone needs them in future;
sodium acetate, sodium nitrate, sodium thiosulfate.

Re: Ammonium nitrate
Hi all,
We are doing the prac 'Measuring the Heat of Solution' which uses ammonium nitrate and sodium hydroxide, and I need an alternative for the ammonium nitrate. Any ideas?
Thanks in advance.

Re: Leaf starch experiment
I wonder if you're leaving them too long in the metho. We leave only until metho turns green. Have the leaves been in the sun prior to picking? Freshly picked seems to work well.

Re: Leaf starch experiment
Hi there, We have good success with this experiment, but our method may be a little different. We boil the leaves first in water, then place in a test tube with metho which is in a beaker of water on a hotplate. Remove the leaf, flood with iodine solution. Young, soft leaves work best. Try a paddle ...

Re: standardisation of NaOH
Hi Lada, The kids here make their own standard Sodium carbonate, then use this to titrate against some hydrochloric that I provide. But I adjust the molarity, so it gives a good titration, and this involves titrating and standardising I guess. I do the same for another prac that involves vinegar and...
