Welcome to the Iowa Science Phenomena website! The goal of this website and service is to create, curate, collect and share a growing collection of user-generated, media-based, standards aligned, science phenomena resources for use in Iowa classrooms, as well as support Iowa teachers as they continue to implement phenomena-based and place-based teaching practices.

There are several ways you can be involved in this project:

Tree roots that would normally be underground have been exposed due to erosion.

Animals as Loggers

Trees can be cut down or stripped of their bark by animals.
