With the help of some students, science presenter Jon Chase investigates the growth of bacteria on agar plates. The students swab some of their personal possessions, including earrings and mobile phones, and then spread the bacteria onto the surface of agar plates. These are grown in an incubator and the results are shown. Jon explains how bacteria grow and reproduce by binary fission.

Students could make models of bacterial cells out of balloons. They could label them with the parts of cells and include relevant functions. After watching the clip, students could repeat the experiment seen, by swabbing and culturing their own samples. (An appropriate risk assessment must be completed). A follow up activity could involve investigating which antibiotics or antiseptics have the greatest effect upon cultured bacteria.
