As spring settles in, we’re already getting glimpses of the oncoming summer. When summer heats up, many of us will begin to long for fall, and the return of the cool breezes which will eventually turn chilly as winter blows in. But have you ever wondered about the science behind the seasons? 

Kids and kids at heart are invited to TLU’s annual Chemistry CHAOS Night on Tuesday, April 15—and this year’s theme is “The Chemistry of the Seasons.” CHAOS (Chemistry Happens with Adventurous Outstanding Scientists) Night is all about exploring chemistry in fun new ways, and this year’s event is perfect for curious minds of all ages.

“Seasonal change is part of the fabric of our lives, as our environment predicably shifts around us,” says TLU Chemistry Department Chair Dr. Alison Bray. “We wanted to highlight the special chemistry of each part of the season, like why leaves change to beautiful fall colors or how snowflakes form in winter.”

Bray says participants can look forward to hands-on activities like separating specific pigment colors from leaves and creating dissolvable snowmen.  “We will have demonstrations on summer favorites like the colors of fireworks and how different types of sunscreens protect us from the sun's rays,” she adds.

The fun-filled evening will include live music and various stations where budding scientists can work with TLU chemistry students to learn about the fascinating world of chemistry around us. 

The event takes place on Tuesday, April 15, from 6–8 p.m. in the Student Activity Center at Jackson Park on the TLU campus. It is free and open to all.
