Studying bacteria

From teachitmaths.co.uk available here https://www.teachitmaths.co.uk/resources/ks4/percentages-compound-percentages/studying-bacteria/17939 Made into a Desmos card sort activity. Students use compound percentages/exponential growth/geometric sequences to find the number of bacteria after a certain amount of time. Students then decide which bacteria would be the most 'dangerous'. Extension: students find how long it would take for one of the examples to double in size.
