This is based off the TIPS (Teachers Involving Parents in Schoolwork) model. Parents LOVE this type of interactive homework and I always receive wonderful comments.
Students should have a basic understanding of density before this assignment is sent home. Parents are NOT required to know the content. The student must do the work. The parent is there for discussion and help.
This homework assignment is perfect when learning that liquids have different densities. The supplies are found in most homes. It is an easy assignment to do and gets the student working with their parent!
