(1) Look at the objects you have been given and predict if you think they will sink, float or remain suspended (neutral buoyancy). Record your predictions. After everyone has submitted their predictions, compare the class predictions and identify those objects whose behavior was most difficult to predict. (See summary data)
(2) Form combinations of blocks (see photos) by tying them together with rubber bands such that the total mass of each combination is less than 120g. Find one combination that will float and one combination that will sink for each of 1-block, 2-block, 3-block, 4-block and 5-block combinations. Determine the masses of each combination and record in the appropriate column of the data table. You may mix blocks from the various sets and use more than one of each material when making combinations.
After analyzing your data and the class data, please answer the following questions. Enter your answers in the quickwrite.
