What are HABs? ...What causes them? ...What can we do about them?

These activities, in conjunction with Bigelow Laboratory's "Toxic and Harmful Algal Bloom" web site, will help your students gain a better understanding of toxic and harmful algal blooms. Each module below consists of background content material and related standards-based activities. Each module is independent of the others; however, some background knowledge is required to complete the lessons. Refer to the "Preparation" section of each lesson for ideas on how to prepare your students. The content and activities on this web site are also available as PDF files.
