Density Laboratory Student Exploration

Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. 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. Click on the image and select EDIT to use the drawing tool. cruise ship and beach ball 2. Why do some objects float, while others sink? If the ​object's​ total density is greater than that of water, it s ​ inks​, but if it is less, it f ​ loats​. Gizmo Warm-up The ​Density Laboratory ​G izmo 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​? 19.5g 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​. A. What is the initial volume of water in the cylinder? B. Place object ​1​ into the cylinder. What is the volume in the cylinder now? C. What is the volume of the object? 14.0ml 1
