Petri Plates\Growing Bacteria Experiment


There are two kinds of my entry, the top one is slangish (Yo bro, innit fun, wassup!, innit blood) and the bottom
one is more what my Dads expectation is.

A longish time ago I want'ed t' do an experiment but it took ages to find one and when Dad finally did I had to nag him for ages and ages and ages and ages and ages and ages and ages and ages and ages since like the 6th until we finally got round to doing it. We have started doing the Homemade Petri Plates experiment but I don't know whether we have done it well so far. Well basically the experiment is making bacteria grow so you can see it.

 You do this mixture of a stock cube, plain gelatine or agar agar, water and sugar and put it at the bottom of disposable containers put it in the fridge or somethin' and well after an age take it out and rub the um... bacteria on and wait another age until you can see the bacteria and... ya.  Just in case you do, don't try this recipe because I was tired and definitely got some of the things wrong so these are two websites that definitely got it right:

Quite a time ago I wanted to do an experiment but it took a very long time to find one and when Dad finally did I had to nag him for a really, really long time probably since the 6th until we finally got round to doing it. We have started doing the Homemade Petri Plates Experiment or Growing Bacteria Experiment but I don't know whether we have done it well so far. Well the experiment is making bacteria grow so you can see it.

Mix together a stock cube, plain gelatine or agar agar, water and sugar and put it at the bottom of disposable containers. Put it in the fridge and after a long time take it out and rub the bacteria on. Wait another long time until you can see the bacteria and that's that.  Just in case you do, don't try this recipe because I was tired and definitely got some of the things wrong so these are two websites that definitely got the things correct: http://kitchenpantryscientist.com/?p=931 and http://www.sciencekids.co.nz/experiments/breedingbacteria.html
