I don’t have photos of this activity, but it’s a fun and easy one to do anytime. Gather some small objects- coin, rock, plastic toys, screws, beads, sticks, etc… Fill up the sink, or a large bowl with water. Before putting the objects into the water, have your child divide the objects out on the paper with the words Float, Sink according to their predictions. After you test them in the water have your child draw or write them onto the graph. You could easily make this chart reusable by laminating it. Click above on the picture to download the chart.
