GCSE OCR Twenty First Century Additional ScienceWatch
Ack. So much science which I haven't visited properly yet! I believe that the CGP books don't actually cover everything too - oxygen debt, molecules which make up DNA backbone and some other stuff was missing unfortunately.
Went through my Biology already.. need to revise it the night before though just as a reminder. Still need to cover Chemistry and Physics Going on BBC bitesize gcse, Sam learning and the cgp then making some notes on the harder stuff and making posters works well for me.

Anyone have any idea's about the possible six markers for any of the Biology additional. Im quite worried B4 is rather straight forward but im a bit stuck on the other two. Any good revision sites ive been using bbc bitesize but im not sure if my CGP book covers all of the modules.
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.
Thanks that was really helpful! I've been doing past paper and getting around 37 to 40 which is an a/a* but some of my teachers told me this year they're planning in raising Boundries higher anyone else hear that?
like in biology the rolled up leaf, we've done about that but not specifically rolled up leaves
i need help
