Can you use volume alone to predict whether an object will sink or float? Explain. 4. Draw conclusion: Can you use mass and volume to predict whether an object will sink or float in water? Explain your thinking. Volume 5. Apply: Measure the mass and volume of the toy soldier: Mass Will it float or sink? Use the Gizmo to test your prediction Get the Gizmo ready: Activity B: Calculating density • Replace the objects on the shelves • Be sure the liquid in the beaker is Water. Question: How does density tell you whether an object will sink or float? 1. Calculate: Density is the amount of mass contained in a given volume. To find the density of an object, divide its mass by its volume. Density is recorded in units of grams per cubic centimeter (g/cm'). What is the density of an object with a mass of 100 g and a volume of 50 cm? 2. Record data: In the Gizmo, find mass and volume of the objects listed below. Then calculate each object's density and record it. Finally, test whether each one sinks or floats in water. Density Sink or Float? (g/cm') Object Chess piece Rock Toy soldier

Place the apple into the cylinder. What is the volume in the cylinder how? The water rises in the cylinder because it is displaced, or pushed upward, by the apple. The amount of displaced water is equal to the volume of the apple. C. What is the volume of the apple? (Use the Object volume to check.) Note: Milliliters (mL) are used for liquid volumes, while cubic centimeters (cm") are used for solids. One mL is the same volume as one cm". The apple's volume is measured in cm". Get the Gizmo ready: Activity A: • Replace all objects on the shelf. • Be sure the liquid in the beaker is Water. Sink or float? Question: How do mass and volume affect sinking and floating? 1. Predict: Which objects do you think will float in water? Which do you think will sink? Record your predictions below in the first column of the table. Prediction Mass Volume (sink or float?) (g) Result Object (cm) (sink or float?) Ping pong ball Golf ball Apple Chess piece Penny Rock 2. Experiment: Use the Gizmo to find the mass and volume of each object and whether it floats or sinks. Record your results in the table. 3. Analyze results: Look at the data in your table. A. Can you use mass alone to predict whether an object will sink or float? Explain.
