How were they different? Which sank right away? Which sank more slowly?.Do all the objects float the same way or do some float differently? Describe what they do.Try putting several objects in the water at one time and let children compare the ways they behave. Point out the picture signs on the plastic bins: “Float” and “Sink.” Have children take their object out of the water and put it in the right bin.What do you think will happen when we put it in the water?.Put objects that sink and objects that float in a bag. Gather children around the water table, tub, or pool.Some float some don’t.Įncourage children to use the words sinking and floating, and science process words such as observe, notice, compare, same, different, change, test, and predict. various objects that float or sink (for example: rubber bands, sponges, pencils, plastic bottles with tops, wooden blocks, plastic straws, craft sticks, small plastic toys).two plastic bins labeled with picture signs: “Float” and “Sink”.water table, large tub, or plastic wading pool (if outside).
