Reef in hot water

How do changes in temperature, light and water quality affect the survival of corals?

Students learn what corals need and why they bleach, analyse example data linking hot-water weeks to bleaching (and how teams of scientists, rangers and citizen scientists collect reef data), then test how muddy water cuts the light corals depend on. Lessons 1 and 2 need only iPads; lesson 3 uses clear cups, soil and a printed reading card.
