This activity may be broken up into two or more days. Read pages 6-8 in Keep it Afloat . Make predictions to which items in the book will float. Pass out the data sheets and crayons. Hold up an item and have students predict whether it will float or sink.
Students color in either the float or sink column.
Do this for each item. Working in small groups students then test whether the item will sink or float. The recorder from the group will mark on the group data sheet their results. Have students compare their predictions to the results from the experiment. Discuss the differences between floaters and sinkers.
