Maine state Science Fair 'Smile Lab'

The Slime Lab session was designed to introduce students to hands-on chemistry through an engaging, sensory-based activity. Prior to the meeting, participants registered through a Google Classroom survey system, allowing us to prepare the necessary materials according to the number of attendees.

The session began with a brief presentation outlining the procedure for creating slime, followed by an introduction to the Maine State Science Fair and a short announcement about upcoming club activities. Students learned how borate ions interact with PVA molecules in glue to form cross-linked structures, which give slime its unique properties. The demonstration explained how ingredients such as water, glue, baking soda, and shaving foam can influence the formation and strength of these cross links.

During the lab activity, all materials were placed at a shared table station, creating a collaborative workspace for club members. Students experimented with different ingredient ratios, with some adding shaving foam to adjust the texture of their slime. Many participants recalled that slime was a popular DIY trend during their childhood in the early 2020s, adding a nostalgic element to the activity.

By the end of the session, members showcased their completed slime creations, with group and individual photos documenting their work. The Slime Lab not only strengthened students’ understanding of polymer chemistry but also encouraged creativity, teamwork, and hands-on scientific exploration.
