Students explore how populations grow — rapidly at first, then leveling off as they reach the carrying capacity their environment can support — and the limiting factors that keep every population in check.
Students will be able to…
No population grows forever — something always slows it down. What limits how many organisms an environment can support, and what shape does that growth take?
Project this and change the carrying capacity. Watch the population grow fast, then level off as it approaches the limit the environment can support.
