Sink and Swim
To analyze the relative density of matter as a physical property and apply the knowledge of relative density to design a contraption to solve the problem of trash in the ocean.
Time Frame:
1 week
In this activity, students investigate water density and how it relates to everything around them. They will also look at congruent cubes with different masses. Density Gizmo
1. The students will explore obejcts to see which sink and which float.
2. The students will be given density cubes, a graduate cylinder, a triple beam balance, and asked to explore which items will sink and which will float. The students will be asked to give a hypothesis of what is causing this phenomenon to happen.
3. The students will then use a virtual lab to look test whether items sink or float.
4. Each group will come prepare a presentation to explain relative sinking and floating using technology.
5. Each student is to post a post a comment to a real world problem supplied by the teacher on the class wiki.
  • 5.5 (A) Matter and energy. The student knows that matter has measurable physical properties and those properties determine how matter is classified, changed, and used. The student is expected to: classify matter based on physical properties, including mass, magnetism, physical state (solid, liquid, and gas), relative density (sinking and floating), solubility in water, and the ability to conduct or insulate thermal energy or electric energ

  • Each group will choose which of the students roles they would like to focus on in their presentation.
The students will review a video clip that I create to analyze what is right and wrong. They will provide there answers on through the class wiki.
