Date:24/11/20Student Exploration: Density LaboratoryDirections: Follow the instructions to go through the simulation. Respond to the questions andprompts in the orange boxes.Vocabulary:buoyancy, density, graduated cylinder, mass, matter, scale, volumeGizmo Warm-upTheDensity LaboratoryGizmo allows you to measure a variety of objects, then dropthem in water (or other liquid) to see if they sink or float.1.An object’smassis the amount ofmatterit contains. Mass can be measured with acalibratedscalelike the one shown in the Gizmo. Drag the first object onto theScale. (This is object1.)What is the mass of object1?19.5 g2.An object’svolumeis the amount of space it takes up. The volume of an irregular object can be measuredby how much water it displaces in agraduated cylinder.A. What is the initial volume of water in the cylinder?400 mLB. Place object1into the cylinder. What is the volume in the cylinder now?414.2 mLC. What is the volume of the object?14.2 cm^3Note: While milliliters (mL) are used to measure liquid volumes, the equivalent unit cubic centimeters (cm3) areused for solids. Therefore, write the volume of object1in cm3.Reproduction for educational use only. Public sharing or posting prohibited. © 2020 ExploreLearning™ All rights reserved
Activity A:Float or sink?Get the Gizmo ready:Drag object1back to the shelf.Check thatLiquid densityis set to 1.0 g/mL.Question: How can you predict whether an object will float or sink?1.Observe: Experiment with the different objects in the Gizmo. Observe the mass and volume of each object,then drag it into theBeaker of liquidto see if it floats or sinks. (Notice a pin holds objects in the graduatedcylinder, whether they sink or float.) Try to determine what the floating objects have in common and whatthe sinking objects have in common.2.Form hypothesis: Compare the floating objects, then do the same for the sinking objects.A. What do the floating objects have in common?that they all have similar numbers for the massand volumeB. What do the sinking objects have in common?that they all have very different mass and volumefor each object3.Collect data: Measure the mass and volume of objects 1 through 12, and record whether they float or sinkin the table below. Leave the last column blank for now.
