hi, i am a biology teacher and took my PGCE at bristol. im hoping that you will be able to help me.
i would like to grow some carrots in test tubes with a low ability group, but i am not sure what sort of transparent nutrient jelly to put in the test tubes so that the students can see them grow. Ive trawled the internet and phoned garden centres to no avail. Is there a recipe i can follow or a brand of nutrient jelly i can buy, that will work?
thanks in advance
liz

What you could use is "agar". It is a nutrient solution and functions as media for fungi and bacteria; I grow my (tree) seeds on it and they are doing fine and germinate quickly.

You can find some general information on: http://en.wikipedia.org/wiki/Agar

A recipe is given on this page: http://www.sciencestuff.com/playground/ … wder.shtml

Good luck and great idea!
