Algae Quest: Evaluation of a Context Based and Active Learning Activity for Primary School Students

Early engagement with science is crucial to broadening participation in STEM, especially in regions with educational, economic, and cultural barriers. Algae Quest is a context-based and active learning outreach activity designed for primary school students (aged 10–11) in Northern Ireland, using the real-world issue of blue-green algae (cyano-bacteria) blooms to introduce concepts of fluorescence, environmental chemistry, and scientific investigation. Delivered to 630 students across 27 groups from 18 schools, the activity aimed to challenge stereotypes about scientists, promote inclusive role models, and foster enthusiasm for chemistry. Evaluation via group responses from 400 students and survey feedback from teachers showed high engagement, increased understanding of chemistry, and a strong appreciation for the hands-on approach. The findings highlight the potential of inclusive, context-rich outreach to inspire young learners and diversify future scientific participation.
