  • Core Practical Potato Chips

    The classic potato chips experiment. Add cubes of potato, of very similar dry mass and size, to glucose solutions of different concentration. Leave for some time, remove and dry. Measure the change in mass.

  • Practical Enzyme rate vs substrate concentration

    A visual demonstration of the impact of substrate concentration on enzyme activity. Rates are demonstrated using different concentrations of hydrogen peroxide added to yeast and soap.

  • Practical pH and enzyme activity

    Using yeast kept in different pH buffers, another very visual demonstration of the effect of pH on enzyme activity.

  • Practical Temperature and enzyme activity

    Again, another visual demonstration of the effect of temperature (using a number of water baths) on enzyme activity
