COSI
Hands-on laboratories, a planetarium, live demonstrations, dinosaur specimens, a miniature city, and rotating exhibitions turn scientific ideas into choices visitors can manipulate.
Artwork inspired by George Bellows
COSI is strongest when an exhibit produces a prediction rather than a button press. Progress, Gadgets, Ocean, Energy Explorers, and the planetarium approach science at different scales, while the American Museum of Natural History Dinosaur Gallery connects reconstructed animals to fossils and comparative anatomy. Live shows matter because a skilled presenter can expose the uncertainty and failed attempts that polished interactives sometimes hide.
Families should choose two anchor areas and leave room for repetition. A child returning to the same water channel or machine with a changed strategy is doing more useful scientific work than racing through every floor. Adults can help by asking what changed, what stayed controlled, and what evidence would overturn an explanation; that keeps the visit collaborative rather than turning every label into a quiz.

Quick guide
- Choose two anchors
- Build the day around two major galleries rather than every floor.
- Ask what changed
- Use one-variable experiments to turn activity into evidence.
How to turn play into investigation
- Predict first
- Ask what you expect before touching a control, then compare the result.
- Change one variable
- Repeat an experiment while altering only one condition so cause and effect remain visible.
- Find live science
- Use demonstrations and staff conversations to see uncertainty, technique, and revision.
- Repeat on purpose
- A second attempt with a new strategy is more valuable than collecting another exhibit.
Good to know
COSI’s strongest learning often looks like repetition, not coverage. Allow children to retest a favorite mechanism; leaving time for a second attempt produces more insight than hurrying toward an arbitrary number of exhibits.
