Australia's Science Forum

In the past we have done bean seeds crushed, cover with honey & Hot water, add a teaspoon of dry yeast & leave the culture to ferment for about 24 hours. Place a drop of Crystal violet on a miroscope slide, then place a drop of the yeast culture on top of the crystal violet, aim to observe the reproduction of yeast cells.

After a few minutes the yeast cells died, and we could not see any thing.
We would like to know what other people do for Cell division.

PLEASE!

Can people please tell me want you do for Cell Divison.

Our kids, even the senior Biology just use pre peprepared slides and large plaster models to demonstrate cell division.

We just use yeast, sugar and warm water it's ready to use within 1/2hour. Then straight onto the slide.

How much yeast & Sugar please?????????? 50-50?

Its hit and miss, but I'd say 2 tablespoon dry yeast 1 tablespoon sugar in 600mls warm water (1 litre beaker) so it dowsn't overflow everywhere.

They do the same here. Plus look at a video on Youtube.

We had a green single celled something dividing right before our eyes, while we were looking at pond water. Don't know what it was, but it took 20mins and was spectacular.
