Global Phytoplankton Distribution

Overview

Using interactive maps of chlorophyll concentration, students will identify patterns to formulate their explanations of phytoplankton distribution over time and space.

This interactive model is one of a three-part sequence of learning experiences related to Global Phytoplankton Distribution. To maximize optimal learning outcomes, it is suggested to complete the series in the following order:

1. Global Phytoplankton Distribution Interactive Model (current page)
2. Phytoplankton Distribution and Watersheds Interactive Model
3. Chlorophyll Concentration and Incoming Shortwave Radiation Interactive Model

This story map is intended to be used with students who have access to a computing device in a 1:1 or 1:2 setting.

Materials Required

Resources Needed Per Student:

• Student Data Sheet (Optional)
• Computer/Tablet
• Internet Access
• Link to Global Phytoplankton Distribution Interactive Model

Directions

1. Using an internet accessible device, students open the link to the Global Phytoplankton Distribution Interactive Model to begin their exploration of this phenomenon.
2. Distribute the Global Phytoplankton Distribution Interactive Model Student Sheet (optional). Have students navigate on their own through the interactive model to answer the questions and complete the activities on their student sheet.

Teacher Note

At the bottom of the ocean's food chain, phytoplankton account for roughly half of the net photosynthesis on Earth. Their photosynthesis consumes carbon dioxide and plays a key role in transferring carbon from the atmosphere to the ocean. Unlike the plant ecosystems on land, the amount of phytoplankton in the ocean is always followed closely by the abundance of organisms that eat phytoplankton, creating a perpetual dance between predators and prey.
