We have used liver and potato for this experiment on a few occasions.However each time our success rate has been dissapointing.Does anyone out there have an experiment that will perform with a better rate of success? Helppppp!!!!!!!

Hi Mother,
the biology teachers[3] are about to do this prac with potatos as they have without any problems for many years
the students cut small pieces with the largest cork borer and then take 0.5, 1.0, 2.0 cm slices to use
i make fresh 3% peroxide solution, diluting fresh 6%
then they follow the method in Biology In Context
hope this may help

Hi mother,
We use junket tablets which are bought from the supermarket. The tablets contain the enzyme Rennin. We make the junket up with milk according to the directions on the packet. The rennin curdles the milk by transforming caseinogen into insoluble casein, producing a jelly-like product.
We have also purchased enzymes from southern biological and used the practicals that come on the information sheet. However they must be refrigerated and don't last long (4-6months).
I like the junket for it's convienience. I always have a couple of packets stored.

Hope this helps.

Our Biology teacher has just downloaded some "simple" enzyme pracs from the internet. Unfortunately no web address on the copy he gave me. If you want a copy I'm happy to fax a copy to you. I can be contacted on 02 4471 5600 (ask for Sandra in the Lab). The teacher is very happy with the results, easy to prepare and excellent results.

Hi Waddle,
I would love a copy of your enzyme prac. We are doing this topic right now, and I'm a bit tired of the same old methods.
mY FAX NUMBER IS 67711979.

P.S. Where is Broulee???

Hi ! Could I have a copy too please ? My fax number is 49511649. I'd really appreciate it

Hi Waddle,
There are probably a lot of us doing this prac who would like a copy!
Would it be possible to post the website on this forum, please?
Many thanks,
Liz

Dear Waddle ,
Sorry to be a pain, but a copy of the enzyme pracs that you have would be greatly appreciated, Fax 42852332. Thanx a bunch

I would like a copy of the enzyme prac too, if you don't mind. Fax No 02 6762 1752. (Attn: Rosalie Murray)

May I hope on the band wagon also.

My fax number is 9823 7662 attn Sue in Science

Thank you.

Have a great weekend

I asked about this earlier in the term, see a few weeks back ,check those replies I found them very helpful. Also substituting liver for silverbeet (no smell and yukky test tubes.)

We just got some awesome results using silver beet for the first time, thanks to this forum!!

We have been happily using potato for years, but one of this year's students is allergic to potato. We were happy to know about the silver beet as a substitute, so we didn't have to mess around with liver.
Thanks everyone!

Julie

Many thanx!

Hi guys,
I was about to put my hand up for a copy of this prac too, but after checking, I have found the labbie "Waddle", hasn't been on this site for over a year. My guess is that she has moved on. Just thought I would let you know, because if you're checking your fax machines daily, you may be waiting a while. I could be wrong, but I don't think you'll be seeing those faxes anytime soon. Maybe someone else has something. Unfortuneately, I can't help with this one.
Cheers,
Lisa
