Edexcel iGCSE Paper 2 Science Topics

I don't know if this thread has already been made, but I was wondering if together we could compile a list of topics for each of the sciences which were not on paper 1 and therefore likely to come up on paper 2.

Many thanks everyone!

^^ this is a really good IGCSE A* biology revision blog (written by a biology tutor at Eton!) and these are the topics he thinks will come up...

•

A question about blood, vaccination, pathogens, bringing in bacterial and viral structure, maybe comparing them to animal cells?

•

Something to do with enzymes, nutrients (monomers, polymers), some detail on elements of the digestive system that have not been covered?

•

Water uptake, osmosis, transpiration stream, potometers?

•

Photosynthesis biochemistry, maybe an experimental question, linking with respiration (hydrogencarbonate indicator experiment for example?)

•

Nervous system – reflex arc and eye structure and function are both ripe for a good question

•

Homeostasis question, on thermoregulation or kidney function

•

A question about cloning that links in with cell division, mitosis and meiosis, asexual versus sexual reproduction

•

Natural selection, evolution, selective breeding, maybe linked to an environmental context (e.g. global warming), or food production (e.g. fish farming)
