edexcel AS biology experiments
moon:
please I need these experiment for edexcel A2 Biology
1. Describe how to carry out a study on the ecology of a habitat to produce valid and reliable data(including the use of quadrats and transects to assess abundance and distribution of organisms and the measurement of abiotic factors, eg solar energy input, climate, topography, oxygen avaliability and edaphic factors.
2. Describe how to investigate the effects of temperature on the development of organisms( eg seedling growth rate, brine shrimp hatch rates)
3. Describe how DNA can be amplified using the polymerase chain reaction(PCR).
4. Describe how gel electrophoresis can be used to separate DNA fragments of different length.
5. Describe how to investigate the effect of different antibiotics on bacteria.
6. Describe how to investigate rate of respiration practically.
7. Describe how to investigate the effects of excercise on tidal volume and breathing rate using data from spirometer traces.
8. Describe how to investigate habituation to a stimulus.
Thanks a lot.

hey thanks guys! :) (though im doing CIE)
Umm, there's a book I have.. it's called biology a level experiments.. i will try to find the e-version of it; (if there is one).
also, go to the biology links topic and look at the thinkwell vids, nice help.

oh hey, this isn't bad.. thanks for the share! However, I have a black cover one and it's way way different/better. I'm still looking myself.. but hey guys try these:
http://www.practicalbiology.org - not bad.
e.g. http://www.practicalbiology.org/areas/introductory/cells-to-systems/microscopic-organisms/observing-protoctista-in-water-using-the-hanging-drop-technique,93,EXP.html
