Harmful Algal Blooms and Climate Change

This module was developed by Robin McLachlan (mclachlan.rl@gmail.com), Angie Boysen, Isaiah Bolden, and Christine Baker, all graduate students at the University of Washington, in conjunction with Jane Addams Middle School, with support from the IGERT Program on Ocean Change and the Program on Climate Change.


Grade Level: 6th-8th Grade

This module invites students to investigate the phenomena of harmful algal blooms on Washington state’s coast and around the world. Lessons integrate ideas from biology and chemistry in a marine context. Students build a conceptual model of harmful algal bloom occurrence and evaluate the socio-economic impacts of climate change on blooms.

The curriculum is written as four individual lessons which can take 1-3 weeks total to complete, depending on student comprehension level and time devoted to class discussion. The lessons are designed so that some can be dropped if needed due to time or resource limitations. The lessons involve PowerPoint presentations, worksheets, videos, readings, and hands-on lab activities. All worksheets, presentations, and documents are included.

This curriculum is written to meet Next Generation Science Standards MS-LS1-6, MS-LS2-1, MS-LS2-2, MS-LS2-3, and MS-LS2-4.
