Floating and Sinking Investigate 1

For our first experiment of the year, we brought five objects from home to test to see if they would float or sink. Here is Tristan explaining what he thinks his objects will do.



Here is video of Tristan doing the experiment. He puts each object in the water to see if it will float or sink.



What happened to your five objects, did they float or sink? Write what your objects are and what happened to them.

Before I began to drop my objects in
the container I studied my objects.
I had written my hypothesis on a paper.
I thought that my five objects would sink but my hypothesis was wrong.The
crayon sunk down,the small pencil floated along with the cap that belonged to a pen,and my small eraser sunk with my pencil eraser.
