Population growth

  of  2

Population growth

Living things, such as rabbits and micro-organisms, need food and water to grow and reproduce. In these games you can control the temperature and how much food and moisture is available.

Population growth is also affected by predators and by harmful substances. Extensions to the games allow you to see how these can affect the growth or rabbits and micro-organisms.

Population game

This activity is an experiment in which you can change the conditions to see how that affects the population of rabbits in an area, or of micro-organisms in a petri-dish.

Once you have looked at how changing the temperature, amount of food and moisture affect the population, introduce some foxes into the area where the rabbits live, or put an antibiotic in with the micro-organisms!
