Chemistry (CHEM253) Density Laboratory Vocabulary: buoyancy, density, graduated cylinder, mass, matter, scale, volume Prior Knowledge Questions (Do these BEFORE using the Gizmo.) [Note: The purpose of these questions is to activate prior knowledge and get students thinking. Students are not expected to know the answers to the Prior Knowledge Questions.] 1. Of the objects below, circle the ones you think would float in water. Predictions will vary. Correct answers are shown: 2. Why...

Chemistry (CHEM253) 4. Analyze: Look carefully for patterns in your data. A. Does mass alone determine whether an object will float or sink? No Explain: Object 12 is relatively heavy but floats, and object 5 is fairly light but sinks. B. Does volume alone determine whether an object will float or sink? No Explain: Object 3 has a small volume but floats, and object 9 has a relatively large volume but sinks. C. Compare the mass and volume of each object. What is true of the mass and vol...
