      Unit 1: Test for starch/fat/reducing sugar/protein; Conducting a quantitative survey.

      Unit 2: Preparing and examining one plant/animal cell; effect of pH/temperature/heat denaturation on enzyme activity; Influence of light intensity on photosynthesis; Production of alchohol by yeast, Osmosis

      Unit 3: Examining the transverse of a dicot stem; Effect of exercise on pulse; Effect of factors on germination; use starch agar to show digestion during germination

      I think those would be the key ones to put focus onto, good luck! :)
