Science 212 Density Lab, Sinks_2020 - Plainfield high School Student Exploration: Density Laboratory Vocabulary: buoyancy, density, graduated cylinder, mass, matter, scale, volume Prior K... nowledge Questions (Do these BEFORE using the Gizmo.) 1. Of the objects below, circle the ones you think would float in water. 2. Why do some objects float, while others sink? It all depends on its density. Things that are denser than water sink, if they are less dense they will sink. Gizmo Warm-up The Density Laboratory Gizmo™ allows you to measure a variety of objects, then drop them in water (or other liquid) to see if they sink or float. 1. An object’s mass is the amount of matter it contains. The mass of an object can be measured with a calibrated scale like the one shown in the Gizmo. Drag the first object onto the Scale. (This is object 1.) What is the mass of object 1? 19.5g 2. An object’s volume is the amount of space it takes up. The volume of an irregular object can be measured by how much water it displaces in a graduated cylinder. Place object 1 into the Graduated cylinder. What is the volume of object 1? 14.0mL Note: While milliliters (mL) are used to measure liquid volumes, the equivalent unit cubic centimeters (cm3) are used for solids. Therefore, write the volume of object 1 in cm3. 3. Drag object 1 into the Beaker of liquid. Does it sink or float? It sinks - - - - - - -- - - - - - - - - - Introduction: In the third century B.C., King Hieron of Syracuse asked the famous mathematician Archimedes to determine if his crown was made of pure gold. This was a puzzling problem for Archimedes—he knew how to measure the weight of the crown, but how could he measure the volume? Archimedes solved the problem when he got into his bath and noticed the water spilling over the sides of the tub. He realized that the volume of the displaced water must be equal to the volume of the object placed into the water. Archimedes was so excited by his discovery that he jumped out of the bath and ran through the streets shouting “Eureka!” Question: How can you tell if a crown is made of solid gold? 1. Think about it: Gold is one of the densest substances known, with a density of 19.3 g/cm3. If the gold in the crown was mixed with a less-valuable metal like bronze or copper, how would that affect its density? The density wouldn’t be exactly 19.3g/cm3. 2. Observe: Drag each of the crowns into the liquid. Based on what you see, which crown do you think is densest? Explain why you think so. Crown B, it fell the fastest meaning it is the heaviest, or most dense. 3. Measure: Find the mass, volume, and density of each of the three crowns. Crown Mass (g) Volume (cm3) Density (g/cm3) A 325.0g 65.0cm3 5g/cm3 B 1250.0g 65.0gcm3 19.3g/cm3 C 306.0g 65.0cm3 4.7g/cm3 4. Draw conclusions: Which of the three crowns was made of gold? Crown B Explain: It was 19.3g/cm3 which is what gold’s exact density is. [Show More]
