Learning Objectives
Students will learn the relative densities of different objects.
Lesson
Introduction (10 minutes)

- Don't make it specific to the items that you are going to use. Let the students give you a list of random items they think will sink or float.
Explicit Instruction/Teacher Modeling (15 minutes)
- Take out the chart with each object listed.
- Have the students reflect on whether they think each object with sink or float.
- Take votes to see who thinks the item will sink and who thinks the item will float.
- Post the chart to use later for closing the lesson.
Guided Practice/Interactive Modeling (10 minutes)
- Pick two of the objects on the Sink or Float worksheet and test out the predictions with the students.
- Organize students into small teams.
Independent Working Time (10 minutes)
- Have students work with their team to finish the rest of the sink or float activity and determine whether their predictions were correct.

- Support: Give struggling students one-on-one assistance over the course of the lesson.
Review
Assessment (15 minutes)
