A lesson plan that I created throught the Virginia Scientists & Educators Alliance is now available! Check it out here: https://scholarworks.wm.edu/vasea_lessonplans/4/

& other lesson plans created by marine science graduate students: https://www.vims.edu/research/units/centerspartners/map/education/profdev/VASEA/lessons.php





Lesson Plan Overview:

This lesson plan was created for high school students (grades 9-12). The procedure for the lesson plan is broken into 4 parts. In part one, the instructor will capture the attention of students by reading aloud “an engaging introduction to phytoplankton” while also displaying supplemental figures that will help students visualize what phytoplankton are and how photosynthesis works.

The instructor will continue to engage students in visual learning in part two of the procedure, by presenting the powerpoint titled “Who’s that Phytoplankton?”. This presentation will prepare the class for the lesson by introducing them to harmful algal blooms; explaining what they are, how they impact the world, and the importance of monitoring their presence.


After the students have had a chance to visualize what phytoplankton are and comprehend the largescale impacts they can have on the environment as well as human life, then they will start thinking like a scientist in part four where they will dive into the literature of harmful phytoplankton, aka interpret the vocabulary terms and breakdown the background information that I’ve provided.

In part four, the students will complete a set of worksheets with 4 activities where they will apply the information they’ve acquired and perform observational, analytical, and critical thinking skills like a scientist.


In activity one, students will investigate the scene of a harmful algal bloom. The will assess an aerial image of a bloom by writing down observations they think may be important for identifying what phytoplankton may be responsible for the bloom. They will then use these observations and the phytoplankton identification guide to formulate a hypothesis about the bloom’s causative species.


In activity two, students will generate data by collecting a water sample from the bloom they observed and made inferences on in activity one and perform phytoplankton cell identifications and counts on the cells in their sample. And by this I mean students will ID and count cut out images of phytoplankton that you have placed in a reusable cup.


Activity 3 is geared towards your more creative students who will have the opportunity to apply key information from this lesson into a sort of art project. Students will invent and illustrate a blooming phytoplankton species. In this illustration they will integrate at least 3 adaptations that phytoplankton have to help them grow.


And lastly, activity 4 is a lesson reflection worksheet for them to demonstrate that they have understood the material.

YORK, Va. (WAVY) — Following our recent heavy rain and hot stretch of weather, algae blooms have been spotted in area rivers.


In photos and video captured by Savannah Mapes – who is researching blooms like this one at the VA Institute of Marine Sciences on the Middle Peninsula – you can see the algae blooms along the York River.

In the pictures, the dark areas are spots where Margalefidinium polykrikoides has been spotted. Nicknamed Marg by the scientists at VIMS, this algae is found in coastal waters worldwide and has bloomed almost annually for the past several decades in the York River area.


Dr. Kimberly S. Reece at VIMS tell me these algae blooms occur most often in the late summer, and can be impacted by many factors including temperature, recent rainfall, and salinity.


In more recent years, blooms have been noted in the lower Chesapeake Bay’s main stem and in the James, Elizabeth and Lafayette Rivers.


The blooms can impact marine life, including oysters in the river – but the human impact is usually minimal. Some respiratory issues have been reported over the years. If you have a reaction to call the HAB Hotline. The HAB hotline at 1-888-238-615 with any questions about human health.

The York River endured a long-lived Margalefidinium polykrikoides bloom this year (summer 2022). I hitched a ride with pilots Sam Chelf and Chase Smith in July and August to monitor this bloom from above.
