G'day,
our Biology teacher reckons they are bloodworms and are a sign of pollution. She learnt this from Streamwatch.
Hope this helps,

Thank you Sue,
I have their website available and their price is not bad. I hope the contrast/staining is OK.
We are looking for minigrids also but they cost more than $25 each there, maybe ISSCO is worth a try..........

Hi All,
has anyone seen good examples of the above?
I am looking for a supplier of some well stained slides....

Hi All, I was asked by my HD recently for maintenance items that the Science department and the school are responsible for, especially during the Christmas break, when contractors and the school maintenance team can get to them unhindered. So far what we have come up with is: Science Department- 1. ...

Hi All,
our favourite mitosis video (from Video Classroom) is no longer working well and we have to replace it. The original supplier doesn't seem to be still in business.
Does anyone have any suggestions for a replacement??

Hi All, it is wonderful how these traditions start, isn't it?? Our geological specimens are numbered after the old Students Geological Specimen Set as supplied by the redundant Geological & Mining Museum, Department of Mineral Resources from The Rocks in Sydney. It is numbered from 1(quartz) to ...

G'day all,
I am very in favour of the boiling water technique but our teachers are very sceptical.
Can you give me more details? How long did you boil it and how soon after it cooled did you use it? We need it (the oxygen free water) to turn methylene blue clear.
Thanks,
~Robyn

Hi Helen, One of my end of term jobs is to dispose of all our dissection meat which we keep frozen until the freezer drawer is full. Fortunately, the abattoir we deal with are happy so far to take back the meat for recycling. (into blood and bone meal I guess.) I can sympathasise with your dilemma.....

Hi All, and welcome back to a new term. Has anyone been asked to supply a sodium dithionite (sodium hydrosulfite) solution as a means for removing oxygen from water prior to photosynthesis and respiration experiments? We need it for year 7, it is only approved for years 11-12, to be used with cautio...

Hello there, If you have these attachments, you can optically induce contrast into living and colourless material under the microscope. If the teacher uses a video microscope that displays to the classroom via a monitor- 1. Phase contrast technique. You need to have the kit which is special phase co...

thanks all, the Fiegerts people worked out well, the Bella Vista number didn't respond.
Only waiting to hear if our cloud chamber works now...............

Hi All,
I am looking to print my own radiation warning sign to post onto the door of where these sources are kept.
A quick look at the forums did not come up with what I require.
Has anyone else seen this sign?

Any ideas??

Hello,
I can fax you our IEC manual if you would like? About 20 pages including experiments.

Hello Diana,
its never been a problem, I guess the heating has softened the wax plug?
Perhaps an ordinary sewing needle would do as they come in some very fine sizes.
Don't forget to do the 'poking' from inside to the outside of the jet hole.....
All the best,
~Robyn

Hi all, this job (therapeutic?) comes around regularly, doesn't it? I wait till I have a plastic bucket of these little suckers. Have ready: a needle pointed dissecting needle; triangular file; pliers, tissues. I find using another bunsen, lit with a tissue draped around the base works well. The sic...

metallic looking plastic button??

Hi Lorrae,
would the cooking flavours available in the supermarket be esters??
Almond oil, peppermint flavouring, artificial vanilla, pinappple, banana, lemon essence?
Their chemical formulae would be available on the internet, I reckon...
Good Luck,
~Robyn

Hi Sue,
we get our lab coats from Victoria at a cost of $26 (+GST) for less than 5 in number. I can PM you with the details if you don't get a better offer. They are new, white and we are very happy with the quality.
Have a great long weekend, too!

Hi,
by Googling 'onion root stain', it comes up with a few ideas that may jog your teachers memory. I have been lucky to have been given an onion root squash with superb mitosis displayed in all it's stages. It's labelled '5 AU stain'-wish I was a histologist to know what that means!
Good luck,
~Robyn
