This assignment works well as a culminating task for the Ontario Grade 5 "Human Organ Systems" science unit. It combines science, health and media literacy, asking students to create an informational brochure that educates other children on the harmful effects of either smoking or sun exposure. It includes a learning goal, success criteria and a rubric based on the Ontario Achievement Chart, which could also be adapted for other junior grades.
My students loved this project! They enjoyed researching health problems that affect them directly, and finding a creative way to share what they learned. I would advise showing students some samples of brochures before they begin. Please let me know in the comments if you would like me to upload some samples from my classroom :)
