Science CheMystery: Halloween STEM Demo with EcosySTEM Ambassadors: October 30, 2025

This Halloween, learning came with a bang, glow, and ooze as a pilot group of our 4th–12th grade students experienced a special hands-on science demonstration presented by our EcosySTEM Ambassadors. The event, appropriately named Science CheMystery, blended chemistry, curiosity, and a bit of spooky-season fun!


Students observed a series of high-engagement demonstrations that showcased:

  • Chemiluminescence (how certain reactions produce glowing light),

  • Mystery mixtures that changed color and texture,

  • Safe, small-scale explosions used to demonstrate energy release,

  • And polymers that oozed, stretched, and transformed before their eyes.

But beneath the excitement, the focus was on scientific inquiry and explanation. Ambassadors shared how reaction rates, molecular structure, energy transfer, and material properties all play roles in what we see during chemical reactions. Students were encouraged to make predictions, analyze outcomes, and connect what they observed to real scientific concepts.

This event offered:

  • Peer-led learning

  • Public speaking and leadership practice for Ambassadors

  • A spark of inspiration for younger learners

  • And a celebration of the joy and wonder of science

We are incredibly proud of our EcosySTEM Ambassadors for their preparation, confidence, and ability to make science meaningful and fun for others.

It was a Halloween treat that ignited learning—and a few bright glows along the way!
