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.
You need to cover activities 1–6 for AS and 1–12 for A-level.
Investigation into the effect of a named variable on the rate of an enzyme-controlled reaction.
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.
Production of a dilution series of a solute to produce acalibration curve with which to identify the water potential of plant tissue.
Investigation into the effect of a named variable on the permeability of cell-surface membranes.
Dissection of animal or plant gas exchange or mass transport system or of organ within such a system.
Use of aseptic techniques to investigate the effect of antimicrobial substances on microbial growth.
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.
Investigation into the effect of a named factor on the rate of dehydrogenase activity in extracts of chloroplasts.
Investigation into the effect of a named variable on the rate of respiration of cultures of single-celled organisms.
Investigation into the effect of an environmental variable on the movement of an animal using either a choice chamber or a maze.
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.
Investigation into the effect of a named environmental factor on the distribution of a given species.
