In this lesson, students investigate and identify various phytoplankton using images that were previously taken with a compound microscope.  Credit:  This lesson is modified from a lesson of the same name created by The Center for Microbial Oceanography: Research and Education&nbsp

Students will analyze a graph showing the amounts of peak energy received at local noon each day over the year changes with different latitudes. 

In this activity, you will use an inexpensive spectrophotometer* to test how light at different visible wavelengths (blue, green, red) is transmitted, or absorbed, through four different colored water samples.

Students observe monthly images of changing vegetation patterns, looking for seasonal changes occurring throughout 2017. These data can be used by students to develop their own models of change.

Students will make a claim about whether changing albedo contributes to changes in Arctic habitats.

In this activity, students will analyze past and future eclipse data and orbital models to determine why we don’t experience eclipses every month.
