Young Scientist

An In-Park Science Inquiry Paper for Ages Five-Adult

A young scientist explores Yellowstone with a magnifying glass.

Students ages 5 and up—you can become a Young Scientist! Purchase your self-guiding booklet for $5 at the Canyon Visitor Education Center or Old Faithful Visitor Center. You’ll investigate the mysteries of Yellowstone by completing activities in the visitor center and field. The 5–9 year old program is offered only at Old Faithful. If you are investigating in the Old Faithful area, be sure to check out a Young Scientist Toolkit, which has a thermometer, stopwatch, and other gear. Once your investigation is complete, you will be awarded an official Young Scientist patch or key chain.

Development of this program was funded by the National Science Foundation through a generous grant to the Yellowstone Park Foundation.

You cannot fish from Fishing Bridge. Until 1973 this was a very popular fishing location since the bridge crossed the Yellowstone River above a cutthroat trout spawning area. It is now a popular place to observe fish.
