Hi everyone,
I had a look through old posts here but couldn't find quite the right thing......so I'm hoping someone can help.......does anyone do yoghurt or cheese making experiments?
I'm looking for something simple that we can do with our junior science classes, years 5 & 6, so it needs to be easy & safe.
Any other microbiology based activities for the youngsters would be greatly appreciated too.
Cheers,
Kiah

Re: Junior science pracs
Hi, Kiah - I have a couple of recipes for both at my 'other' school, but sorry, haven't had time to transfer all my resources yet.
I'm sure someone else will give you directions today, but you could always try googling, or try 'wikihow' or professor Bunsen, or the ABC Science site - any of those have simple recipes.
Have fun!

CHeck out this website for simple yogurt instructions. www.instructables.com
In the past I've begged baby food jars from school mummies and sterilised them in Miltons.
Incubation can be done overnight in a frypan on a thermostat with a trviet or something in to keep the jars off the hot base of the frypan.
You could also inflate a balloon using yeast.
First inflate and deflate a balloon a few times so that the rubber is stretched a little.
Put one packet of yeast into a soft drink bottle, add warm water and sugar.
Put the balloon over the mouth of the bottle and tape it if necessary to keep it sealed.
Balloon should inflate as the yeast produces CO2.

Re: Junior science pracs
Thanks for the help & recipes everyone!
I had time to do a bit of googling this morning (takes time to trawl through though ) & found a couple of sites with simple yoghurt instructions too.
http://www.landlearn.net.au/curriculum/ ... oghurt.htm & http://www.greenlivingaustralia.com.au/yoghurt.html
& one for cheese making......http://www.greenlivingaustralia.com.au/ ... ecipe.html
Plus a junior science site full of links & activities that look interesting.......http://www.erl.vic.gov.au/kids/science.htm
Cheers,
Kiah
