Would you plan to visit a local science museum to see new seasonal exhibits?
The Center of Science and Industry (COSI) in Columbus has introduced seasonal autumn programming, including a science demonstration on leaf color changes. The museum is also hosting a new Mickey Mouse Clubhouse exhibition.
Why it matters
These additions represent the ongoing effort by the institution to integrate seasonal biological phenomena into public science education. They follow the museum's established strategy of pairing specialized hands-on science activities with rotating exhibits to maintain local engagement.
The leaf demonstration employs chromatography, a method used to separate chemical mixtures by passing them through a stationary phase. This technique isolates leaf pigments, revealing the underlying colors hidden by chlorophyll.
The players
COSI
A science museum in Columbus, Ohio, that manages interactive educational exhibits and recurring public event series.
The details
Chromatography works by dissolving leaf pigments in a solvent and allowing the mixture to migrate across a substrate, such as chromatography paper. Because different pigment molecules have varying affinities for the paper and the solvent, they move at distinct rates, effectively separating them. This allows visitors to visualize the specific compounds, like carotenoids or anthocyanins, responsible for fall foliage colors.
Timeline
October 2026: COSI began featuring new fall science experiments and exhibits.
The Tech Race
This programming aligns with the museum's broader strategy for rotating interactive science experiences, consistent with its established COSI After Dark event model. It marks a shift to seasonal thematic integration for local public science engagement.
Residents can access the leaf color science demonstration and the Mickey Mouse Clubhouse exhibition at the museum site in Columbus. These attractions are available as part of the museum's current seasonal offerings for the public.
The takeaway
The museum continues to focus on seasonal science, providing a practical look at the chemistry behind autumn foliage. Visitors can monitor future museum announcements for changes to the rotating exhibit schedule.
