Lesson: Life After Trash - Teach Engineering
Grades
6 to 9tag(s): critical thinking (141), engineering (141), problem solving (246)
In the Classroom
A week or so before conducting this simulation activity, ask students to bring in recyclables and clean trash from home. This will cut down on the amount of trash you need to collect, and it will add variety to the supplies. Set up the activity by talking about trash, where it comes from and where it goes. Discuss better alternatives for trash "disposal" such as recycling and reusing. Have students think of obvious reuses for materials and then explain that there are other alternatives to obvious uses. Introduce the activity and basic rules and safety to the students. Arrange them in groups of three or four and then allow them to "shop" the classroom "landfill" to create new things out of old trash. Follow up with discussion of group products, uses, and real life applications of this idea such as recycled art.Add your comments below (available only to members) | Become a Member
