University of Maine Cooperative Extension 4-H plans to offer an online weekly club for youth 13 to 18 years old about Maine’s tidepools and how to be citizen scientists.

The club runs from 4 to 5 p.m. Tuesday, April 12, through Tuesday, May 17. An optional field day will be held Friday, April 22, with a rain date of April 21, at Southern Maine Community College, 2 Fort Road, South Portland.

The 4-H Tidepool Immersion Discovery Ecology Workshop Series will explore the intertidal zone while contributing to marine science research, according to a news release from the Orono extension. Participants can learn about animals that might be seen during low tide and how to identify them using photos taken with a cell phone.

Additional topics are invasive species, climate change, species identification and how to participate in research.

UMaine Extension 4-H professional Sarah Sparks and University of New England graduate student Emily Pierce will lead the workshop.

The workshop is free; participation is limited to 15. To receive the link and materials, register by Thursday, March 31, at extension.umaine.edu. For more information or to request a reasonable accommodation, call 207-581-8206 or email [email protected].

This workshop is supported by the Maine Established Program to Stimulate Competitive Research (EPSCoR) at the University of Maine.
