With such curriculum gaps, it is hardly surprising that middle school children's understanding of botany is limited and riddled with misconceptions. Knowing that plants supply the oxygen to sustain most life forms and provide the primary energy source of most food webs is a core idea of science. Investigating non-native species is one way to "invade" the science curriculum with the study of plants. Despite the dire ecological consequences of invasive species, few curriculum materials address this topic in a substantive manner. The Alien Invaders activity based on the 5E learning cycle uses interdisciplinary and community-based activities to give students a beginner's level understanding of plant adaptations and a comprehensive overview of the serious ecological problem of invasive species. Lessons include elements of guided scientific inquiry and offer motivational learning experiences that are ideal for middle school students. Numerous opportunities for oral and written expression are included. This activity relies heavily on educational resources drawn from the internet and incorporates opportunities to make literacy connections.
