Lesson Plan 4

 (Activity)

"ZONATION AND DISTRIBUTION PART II"

ACTIVITY:

For this exercise, you will be visiting a site on the internet that posts "false color" image maps of phytoplankton in the ocean. By viewing these maps, students can observe that phytoplankton are most heavily concentrated nearest to shore. The directions for accessing one of these sites is given on the next page.

Discussion
Have the students compare the maps for different areas of the world or different times of the year and relate their findings in a group discussion. Generally, the more sunshine and nutrients that are available, the more phytoplankton there will be. Point out to the students that there is almost always more phytoplankton closer to shore than there is in the open ocean.
