"Making Every Second Count": Utilizing TikTok and Systems Thinking to Facilitate Scientific Public Engagement and Contextualization of Chemistry at Home

TikTok is a social media video-based phone application which enables creative and engaging videos to be shared on social media platforms worldwide. TikTok has been applied to create fun, exciting, and engaging 15-60 s long chemistry outreach educational videos, to encourage public dissemination of science with a systems thinking approach. With the creation of an online TikTok account called "The Chemistry Collective" by undergraduate students, 16 educational videos were created, with approximately 8,500 views. Upon surveying participants, viewers of these TikTok videos strongly agreed that they had learned something new about chemistry since watching these videos (4.66/5.00) and had an increased interest in chemistry (82.7% agreed). As such, TikTok can be used to enhance public and undergraduate student engagement with chemistry and science education, together with facilitating the ability of the public to understand how chemistry can be fun, can be performed at home, and is part of our daily lives.
