Reflection: Floating and Sinking- Sorting in Science - Section 2: Presentation of Lesson


Prior to this lesson, I collected about ten items that I wanted to use in the floating and sinking experiment.  I planned on having the remaining students find objects around the room that they wanted to experiment with.  Sometimes the most interesting part of a lesson comes from something that a student comes up with rather than something that was planned.  However, this did not work out so well in this lesson.  My students were having a very hard time finding things to bring up.  I suggested to one student to bring up something from his pencil box.  He brought up his scissors.  After that, all of the remaining students wanted to use their scissors.  I told the students that we needed to try something else since we already knew that our scissors sink.  Having the students try to think of something to use for the experiment ended up taking a very long time.  The other students were starting to get restless, and I ended up just saying things like, "Go get a Lakeshore Kid Counter from the math centers.  Go get a paperclip from my desk."  In the future, I will pull out enough objects for everyone.  At the end, I will ask the students if there is anything else they would like to try, and I will let two or three students who already have something in mind, try additional objects from the classroom.
