This comprehension activity, aimed at students aged 11-14, looks at the role of the immune system in protecting us from infectious disease, and how it recognises the difference between the body (‘self’) and invader. This worksheet is part of a collection of materials based on...

As the number of cells in a microbial culture increases, turbidity increases. In this experiment students calculate doubling time and growth rate constant using absorbance as the measure of growth. Turbidity is caused by suspended cells in the growth medium scattering light, and may be measured using a colorimeter...

This experiment is a continuation of Determining Doubling Time. Students create a standard curve of absorbance against yeast concentration, and use this to determine the concentration of yeast produced over time.

The standard curve (dry mass, grams per litre) is generated from known concentrations of dried...
