Has anyone prepared yoghurt slides in Yr 11 Biology ? :-(
If so - were they successful and what is the secret in preparing them ?? :oops:
Thanks for any help

I've never done this, but I just googled it and multiples sites came up.
The first one said:
1.Take a very small drop of yogurt with the toothpick and smear it for 2 to 3 seconds on the slide.
2.Place a small drop of methylene blue solution on a microscope slide (optional). ...
3.Place a coverslip on top. ...
4.View in the compound microscope at 4 x or 10 x initially, before moving to higher magnification.
