Abstract
Invasive species education is often directed toward adult audiences because they make landscape and pet ownership decisions. However, youth represent an important and underutilized audience for prevention messaging, particularly in Florida where many commonly recognized plants and animals have invasive potential. Over multiple years of 4-H summer camps, a series of youth-centered lessons was developed to translate complex invasive species concepts into age-appropriate, action-oriented learning experiences.
This program integrates play-based learning, visual aids, and experiential activities to improve comprehension of invasive species identification, ecological impacts, and dispersal pathways. Instructional components include a scaffolded presentation with guided notes, small-group analysis of invasive houseplant fact sheets, vocabulary-building activities, and a movement-based relay race that models wind, animal, and human-mediated spread. Additional reinforcement strategies such as coloring sheets and word searches support varied learning styles and literacy levels. Houseplants were intentionally used as the primary teaching examples because they are familiar to youth and provide a tangible connection to household decision-making.
The educational approach is grounded in active learning and experiential education, emphasizing participation, repetition of key terminology, and real-world application. Evaluation across program years used post-activity questions and informal observation to measure knowledge gain and concept retention. Participants consistently demonstrated the ability to define invasive species, identify examples, and explain multiple pathways of spread. Youth also articulated prevention behaviors, including keeping certain plants indoors.
From 2024-25, 93% (n=39) of participants could identify an example of an invasive species. 100% (n=17) could explain a method of how invasive species spread and 100% (n=17) understood why invasive species are destructive.
Framing youth as environmental communicators rather than decision-makers increased engagement and positioned them as contributors to household and community awareness. The methods presented are low-cost, adaptable to multiple settings, and easily implemented by Extension agents, educators, and volunteers.
