The exam is near and I still feel a little unsure..how are you guys feeling about it and do you know any good websites to revise from ? I already using bbc bitesize and sam learning. Do you have any predictions about what the 6 mark questions might be about ?

Looking at the B1 B2 B3 exam, it seems the 6 markers are impossible to predict!

To be honest I agree with you. I found the core science pretty easy though. Need to get a grip and revise additional now

K, I've just written a list. Hope this helps you.. there are just so many possibilities. ;l
Mhmm.. okay, I'll try and make a little list of possibilities.

B4 Six Markers:


Comparing parts of plant/animal cell, what they do, how they help respiration.
Explaining how enzymes work + analysing/explaining data? How pH/temperature affects? Graphs?
Comparing aerobic and anerobic respiration and the advantages/disadvantages?
Comparing uses of fermentation. (Biogas/Bread/Alcohol). Maybe some explanation.
Explaining rate of photosynthesis, limiting factors, etc + analysing/explaining data.
Taking a transect/using a quadrat/light meter/ identification key.
The differences between diffusion/osmosis/active transport. Perhaps analysing/evaulating data? (I HOPE THIS ONE ISN'T USED! ><)
Comparing respiration between human cells/plant cells/bacteria cells.



B5 Six Markers:

Explaining how proteins are made by ribosomes.
Comparing Meiosis and Mitosis.
Comparing Adult Stem Cells and Embryonic Stem Cells + ethics?
Explaining how to clone using stem cells.
Explaining how to clone plants. (Cuttings, meristems, rooting powder, etc).
Explaining Phototropism and Auxins + analysing/explaining data?


B6 Six Markers:

Comparing CNS and PNS. Maybe just explaining either?
Explaining how the CNS coordinates a response with a given scenario (like, a bird sees a cat).
Explaining Synapses + why impulses can only go one way.
Explaining the reflex arc with a given scenario. (Sarah's leg still reacts when the doctor hits it with a hammer).
Explaining simple relflexes with different examples. (Sea anemones wave their tentacles when stimulated by pray's chemicals, molluscs close their shells, human eye contracting with increased light, etc, etc,).
Explaining Pavlov's dogs/conditioned reflexes.
Comparing brain development between child and adult + explain. Possibly explaining data. Maybe even comparing normal and feral children.
Different ways to study the brain + ethical issues.
Explaining how memory works + model.
