Reflection: Performance Tasks That's Fruity-Even More Explorations of Density - Section 2: Investigation and Discussion


During this lesson, the students conducted an investigation on whether grapefruits and kiwi would sink or float.  The students applied what they learned about density to this investigation. I really had no intentions of doing this investigation, but when my student brought in the bag of fruit, I just knew we had to do this investigation.

I wish though, I would have treated this investigation as a performance assessment.  The students really had to apply what they learned about density during our other investigations.  They were making important connections between the different fruit.  All I would need to do is circulate among the students and listen to their predictions and ask clarifying questions as needed to assess them.

Next year, this will not be simply a lesson, but an assessment.  I will take the time to make an observation form and rubric that I can use to record my students' learning and understanding.  I think it will be a great way to find out what they know and how they apply their knowledge.

That's Fruity-Even More Explorations of Density

Unit 6: Sink or Swim
Lesson 5 of 11

Objective: Students will be able to use what they know about density to make and test predictions about whether kiwis and grapefruits float by conducting an investigation.

Big Idea: In previous lessons, the students have had the opportunity to test a variety of fruits to see if they sink or float. Can they apply the knowledge that they have gained to kiwis and grapefruits.
