Whoaa Nelly.......you wouldn't believe it - now that i have pulled it all out of the cupboard - my HOD thinks she might want to keep it after all. 5 years of no use - tis bit like the juicer really - once it goes in the cupboard - it doesn't get used. No wonder I drink.!! But watch this space - we m...

Morning Everybody - I hopefully have attached a list of all the sensors and there codes - we bought most of them in 2003 and some are still unopened. The only one i would be concerned about would be the dis O2 sensor as the membrane is so delicate and it has been years since we have used it. I had p...

Our school is looking to part ways with all our pascoe equipment. We have had it for quite a few years now - with very little use (used under 20 times in 8 years). What a waste. We have alot of sensors - motion, force, pressure, voltage, acceleration, pH, calourimeter, dis O2, EKG, heartrate, respir...

Hi kerri - we did a prac today - we used our electrical conductivity plates. There is a plate that is meant to rest on the top edge of a small beaker with a plate that hangs down into a solution - there are two terminals at the top which you attach your power to and a light bulb to indicate conducti...

Sooooooo - on that knowledge - since there is enzymes in green capsicums and minimal in the yellow , could we summize that there would be enzymes in red capsicums and minimal in orange. As they are both just ripe versions of the green and yellow.....? I am going to give it a go with the peroxide ......

You can get them from any BOC or norstate gas. Not sure if you have them down south but anywhere your tradies get their gas you can pick them up.

OHHHHHHHhhhhhhhh! 8O Why didn't you tell me about the tongue thing earlier. It dammed well worked - and gave wonderful results - but only if I stuck my tongue out just ever so slightly to the left. We have put it down to our qld capsicums - bought the last lot on special - we recon that the yellow o...

I am tellin ya!! Going aroung the bend with it. Stock is only newly purchased - have just completed the liver enzyme experiment and the same H2O2 worked fine.

I made the Hydrogen peroxide up fresh - I tried a 3 % , 6 %, 15% and full strength. The stronger it got - the smaller reaction we obtained- at full strength it caused the capsicum juice to clear. The green capsicum gave maybe a ml of froth and the yellow capsicum gave 2 or 3 ml. I checked out your t...

Thought i would grab your attention Sass - need help with capsicum prac. dowesn't appear to be working. Which concentration should froth the most on the green. froth so far is very minimal .???????/

Hey Sassi - HELP! We are sitting here - biol teacher and me - we can not get the capsicum to froth up - is there something obvious we are doing wrong. One class did it yesterday and got the same results for the yellow as green. What concentration of hydrogen peroxide did you use.?

gosh Pommy - I was scanning the topics - this one sounded like a pearler . I was thinking along the lines of "is it me or is the size of the ....certan male teachers brain (who drives me nuts on a daily basis) shrinking!!! I do believe so or Is it me or is the size of the ................back c...

Arghh Carol - thank you...thankyou ....thankyou. I could get used to being lazy.
cheers
Kim.

Being entirely lazy here - haven't used our hoffmans generator for a whole year and i can not remember the concentration of sulfuric acid that we used. :coffee: I really should get off my butt and look through my files but I really do not want to right now. Don't expect you guys to go looking for th...

Breathe Sassi .....Breathe......only an hour to go!!!! Then a big glass of wine might ease the pain.

Goodmorning Sassi .... Received your fax -really appreciate it - thankyou.


Kim.

Hi Sassi - I think i must have a gumby computer as I can open the "graph" file but not the actual practical - it tells me that the file is damaged. Would it be at all possible that you could fax it to me . 0749399610 . I am grovelling ....... pleassseeeeeeeeeeeeeeeeeee. (I have got my most...
