Biology practicals apparatus set-up guides
We’ve worked with experienced teachers and technicians, as well as higher education institutions and learned societies to produce these apparatus set-up guides for each of the required practical activities.
Practicals are at the heart of our new AS and A-level Biology specifications – so it’s important to get them right first time in the lab.
Required activities
You need to cover activities 1–6 for AS and 1–12 for A-level.
Practical 1
Investigation into the effect of a named variable on the rate of an enzyme-controlled reaction.
Practical 2
Preparation of stained squashes of cells from plant root tips; set-up and use of an optical microscope to identify the stages of mitosis in these stained squashes and calculation of a mitotic index.
Practical 3
Production of a dilution series of a solute to produce acalibration curve with which to identify the water potential of plant tissue.
Practical 4
Investigation into the effect of a named variable on the permeability of cell-surface membranes.
Practical 5
Dissection of animal or plant gas exchange or mass transport system or of organ within such a system.
Practical 6
Use of aseptic techniques to investigate the effect of antimicrobial substances on microbial growth.
Practical 7
Use of chromatography to investigate the pigments isolated from leaves of different plants, eg leaves from shade-tolerant and shade-intolerant plants or leaves of different colours.
Practical 8
Investigation into the effect of a named factor on the rate of dehydrogenase activity in extracts of chloroplasts.
Practical 9
Investigation into the effect of a named variable on the rate of respiration of cultures of single-celled organisms.
Practical 10
Investigation into the effect of an environmental variable on the movement of an animal using either a choice chamber or a maze.
Practical 11
Production of a dilution series of a glucose solution and use of colorimetric techniques to produce a calibration curve with which to identify the concentration of glucose in an unknown 'urine' sample.
Practical 12
Investigation into the effect of a named environmental factor on the distribution of a given species.
