ONE WATER CYCLE: Climate Change and the Ocean Habitat

Project Description

In this project, students learn about the impact of climate change on the ocean’s habitat. This includes extremely warm climates, extremely cold climates, and natural phenomenons that occur in water based on the temperature. This unit is grounded in the biology concept: Law of Tolerance (a set of environmental conditions within which an organism can best survive and reproduce). Factors that impact the law of tolerance are: Salinity, pH, Temperature, and oxygen levels. Each of these (abiotic) factors will impact different things in the ecosystem and students will experience those changes through chemistry lab work. Students will explore different blue careers related to these concepts such as Marine Conservationist Photographer, Commercial Diver, Marine Biologist and Filmmaker, Hydrologist, Geoscientist, and Aquatic Toxicity Testing Support. Students will investigate and research the ocean’s ecosystem and how these changes impact our world as a whole. Students will take action as they compare and contrast two environments, the difference between temperatures, and impact on growth of plants and animals in those environments. Students will take the advice of the career experts that they learned about during this unit and create an ideal state campaign for a specific audience around aqua-optimism in the medium of their choice. Their campaign will be shared with a public audience encouraging others to take action as well.
