Much of science deals with constructing explanations of how things change and how they remain stable. What Students Will Learn in this Lesson 1 minutes Students will set up several hay infusion cultures to model succession.

The purpose of this two week lab is to help students better understand ecosystem dynamics, functioning, and resilience.

By studying the changes in a hay infusion over a two week period, students will gain an appreciation of a ditch by the side of the road, an ecosystem they see every day on their way to school.

Students will model the ditch ecosystem in an Erlenmeyer flask. The protists that they will view include several plant-like protists, fungi-like protists, and animal-like protists both free-living and parasitic.

Later in the lesson, students will revisit their predictions and learn more about the classifications of protists.

They will need to make some sketches of what they see in their lab notebook. Students will be making daily observations for about 2 weeks. I like to start this lab on a Friday so that the cultures will have the weekend to mature.

Since the hay infusion culture has had no time to mature, it is unlikely that students will see anything but hay particles on their wet mount slide today.
