Sink/Float Activity Sheet. Activity #1

  • What was the point of this activity?

The point of this activity was to show density and help define “less dense” and “more dense”.

  • Explain how you would introduce this to your class?

I would introduce this activity the same way as the activity sheet.

  • Where do you see students having difficulty?

I see students having difficulty with understanding that no matter if an object is small, it doesn’t always mean that it will float.

  • What changes or extensions could you do to this activity?

I would have the students give examples of what will float or sink.

I would introduce it by teaching the subject of physical and chemical changes.

  • Where do you see students having difficulty?

I see students having difficulty with measuring and the students might not see past the fun.

  • What changes or extensions could you do to this activity?

I would have the teacher make the slime instead of the students.
