FUN recycling-related density unit project! Requires no supplies!
Covers NGSS MS-PS1 and MA MS-PS1-7.
In this activity, students are first introduced to the problem - an engaging scenario in which several recyclable materials have been mixed together. Using their knowledge of density, students are challenged to design a recycling factory that can separate the materials. First, they will create a rough draft of their factory plan that will be signed for approval by 3 "colleagues" (classmates or teacher). Then, they make a final draft poster showing their factory and how they use density
to separate the materials. Additionally, there are also instructions for a letter writing component (to request the recycling job). This letter writing portion of the assignment is an optional extra.
Supplies for this project are simple - paper and colored pencils and markers.
Additionally helpful (but NOT necessary to complete the project!) are a milk jug, soda can, soup can, green soda bottle, and magnet.
A simple, student-friendly rubric is included.
