In this outdoor activity students learn how invasive species can catch a ride on humans, pets or personal items and be transported to a new location. They consider the impact that invasive species can have on these new areas and how to stop their spread.
After being introduced to the concept via the additional resources, students participate in an activity of the teacher's choosing. Following the activity students conduct a thorough cleaning per steps provided in the guide to remove any natural material that may be stuck to their clothing and gear. They then use the Hitchhiker Tally Sheet (provided) along with sketches and photos to record what they have found. Back in the classroom students observe, identify and discuss what they collected. As a culminating activity the students will take the 'Play Clean Go' pledge. Additional extension activities are also provided.
'Don't Pick Up Hitchhikers' is a great hands-on activity to conceptualize the idea of invasive species. It also allows the students to see first hand how easily materials can be transferred from one area to another. This resource could be used in all Science classrooms from Grade 6 to 12 to discuss protecting habitats and ecosystems.
