Coral Reef Senior High School - APES 102Density Laboratory GIZMO

Document Content and Description Below

Student Exploration: Density Laboratory Vocabulary: buoyancy, density, graduated cylinder, mass, matter, scale, volume Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. Of the objects ... below, circle the ones you think would float in water. Beach ball, cruise ship, and saturn 2. Why do some objects float, while others sink? It depends on the density of the object, and because or their weight. 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. Mass 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? 19.5 g 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. A. What is the initial volume of water in the cylinder? 400.0 ml B. Place object 1 into the cylinder. What is the volume in the cylinder now? 414.0 ml C. What is the volume of the object? 14.0 cm3 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. [Show More]
