Bridge Expansion Joints
To compensate for the temperature fluctuations, among other things, bridges cannot be connected to the roads. Instead engineers use expansion joints to allow the bridge to move.
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:
- Browse or search the site to find an Iowa-based phenomenon to align to your learning standard.
- Grow your phenomena skills and knowledge with our Iowa Science Phenomena Teacher Guide.
- Equip your students to engage their own curiosity and be phenomenon-finders for themselves with the Iowa Science Phenomena Student Guide.
- Capture and share your phenomena to the project.
