This activity was prepared by David Walker (LASA High School) and Rose Cory (University of Michigan), based on work conducted during summer 2019 at Toolik Field Station in Alaska. The purpose is to expose students to photooxidation, one of the main pathways by which organic molecules in Arctic streams are oxidized into carbon dioxide. Different teas will be used
Students will build a simple plankton net from a nylon stocking, then (optionally) use it to collect plankton in ponds, lakes, streams, bays, oceans, or even aquariums.

It's All About Repetition!
In this lesson, we will learn what repeat photography is, and discuss how it can be used in scientific analysis.
Introduction
What is repeat photography? It is the taking of photographs from the same location, over time, to document changes. This tool has become extremely useful in science, as a qualitative way to
