Maybe this is something to do with the concentration (>99%) and in large quantities

Oh!- and no need to soak before freezing.

Hi Rae,
I usually freeze eyes( when I can get them!!)in Normal Saline(0.9%) and freeze in takeaway containers, lens towards the bottom of the container. I was told that helps to keep the lens clear.

The slides I made way back when with this mountant didn't dry properly either. Interested to hear what others have to say...!

Hi Sujatha,
Whereabouts is Kingswood in WA?

In WA we also have to apply for animal ethics permission to dissect rats even though they are already dead- and need to apply a minimum of 8 weeks or so in advance! Haven't done them for a very long time now which suits me just fine

Good question Darryl. I am very interested to hear what other schools are teaching in year 10. Maybe we could have a poll- who specialises in year 10, who leaves it until 11,12?

Hi Sassi, Does the grey and wess mountant dry so that any excess can be trimmed with a scalpel and peeled off the slide - like you can do with DPX? I made some up- love the resulting product \:D/ \:D/ \:D/ but was wondering how well my slides will tidy up. It has been many years since my slide makin...

Feulgen's or Gallocyanin-chrome alum would also do it but none are really suitable for a school lab.

We are still getting ours- and love them too!! They have really been useful for all sorts of pracs- used by year8s through to 11s. And the freebies -dvd, poster etc- are good fun as well. All in all, a great investment and thankyou so much Fibreweb for putting us all on to it!

Oh, Kim! Don't you hate it when they don't work- I have had more enzyme pracs fail than I care to admit :whistling2: We did have success with this one though. I blended about 6 green capsicum with 100ml distilled water- made about 500ml capsicum juice, and used freshly made 10% hydrogen peroxide. Re...

Thanks Sassi! Going capsicum shopping today!!

Hi Sassi, Thank you for posting this prac =D> . My teachers are keen to have a go. Could you tell me approximately how many capsicum you blend up- also is it just enough water to cover, or more :unsure: :unsure: ? Capsicum extract is a new one for my repertoire but I am willing to try!! Thanks heaps...

Sharing your pain Sassi- you are not alone! I kind of missed this place a bit though- a bit sad isn't it?!
Enjoy your day!

No worries, Richard

I have some model rocket engines that came with the instructions:Do not use damaged model rocket engines. Soak them in water for a day or two until they come apart, then put the remnants in the bin outside.
Sounds easier than trying to get the powder out!

Our first issues arrived today- they look fantastic! The blocks are quite a reasonable size and the photography and info in the booklets are great. Judging by the reactions of several students who happened to be walking by they are destined to be a big hit. Useful for not only lower school classific...

No- it doesn't work.

Hi Kimmy,
Check to see if the little tab on the video tape has been removed. If it has I don't think you can copy it to dvd- or video. It is the protection mechanism to prevent something being taped over it.

Hi Lyn,
As the surveys were being sent to the principals, perhaps it hasn't reached the out basket yet?? Might pay to check with your HOD as well. It is probably there somewhere...
