The students did an experiment in the classroom where they grew bread mould to study microfungi.
Day 1 - The bread was made wet with only water, this bread was placed in a zip lock bag and kept in a warm place to promote the growth of microorganisms.
Day 7 - In just a week the results were shocking, on those wet places the microfungi grew rapidly.
Students were excited all week long as they could then see how the theory relates to the practical outcome of how microorganisms can grow.
