Lab description and primary aims of the lab: 

In 1962, Rachel Carson published 'Silent Spring', which drew attention to how the use of pesticides was indirectly decimating bird populations by causing thinning of egg-shells. This model illustrates how DDT in near-shore waters accumulates in a 'food chain' of phytoplankton, zooplankton, smelt, salmon, and pelicans.
