In this activity, students observe how chicken eggs can be used to simulate the potential effects of increasing ocean acidity on marine animals with calcium carbonate shells or skeletons, for example, bryozoans and cockles.
By the end of this activity, students should be able to:
- understand about ocean acidification and the possible impacts on shelled marine animals
- conduct an experiment that tests the effects of solutions of varying pH on eggshells.
