Sink or FloatBy Jenna Richter | April 6, 2016 | Science
Today, in small group time, I had the students make and test predictions about sinking and floating and then classify objects according to whether they sink or float.
I asked the students to each choose two objects from our studio area that were smaller than the palm of their hand and wouldn’t be ruined by water for our experiment. Next, they wrote the names of the objects on a sink/float chart.
After all the items were on the chart, students made predictions about which thinks would float and sink.
Finally, we put our theories to the test. Some of the things floated at first and then became waterlogged and sank to the bottom. By the end of the experiment, only the cork and the googly eye were on the surface of the water.
