Get the Gizmo ready: Activity A: 1 Float or sink? Drag object 1 back to the shelf. . Check that Liquid density is set to 1.0 g/mL. 6 Question: How can you predict whether an object will float or sink? Collect data: Measure the mass and volume of objects 1 through 12, and record the mass, volume, and density. Object Mass (g) Volume (cm3) Float or sink in Density water (density =1 g/? 19.5 g 14 cm3 Sink 1.41 ll g 9.2 cm3 Sink 1.2 3 4.1 g 5 cm3 Float 0.8 4 133.9 g 7.4 cm3 Sink 19.3 5 4 g 3.5 cm3 Sink 1.1 6 78.3 g 29 cm3 Sink 2.7 2.5 g 20.8 cm3 Float 0.1 24.2 g 26 cm3 Float 0.9 9 99 g 44 cm3 Sink 2.3 10 42.1 g 61 cm3 Float 0.68 11 65. 5 g 40 cm3 Sink 1.58 12 104 g 114.1 cm3 Float 0.91 In answer to the question: How can you predict whether an object will float or sink? There are three possible claims: You can predict whether an object floats or sinks based on its volume. You can predict whether an object floats or sinks based on its mass. You can predict whether an object floats or sinks based on its density.. Which claim is accurate based on your data? Describe the evidence you have to support this claim. - The accurate claim is the third one, that is, "You can predict whether an object oats or sinks based on its density." - a. This claim is accurate: "You can predict whether an object oats or sinks based on its density." From the data given, we can illustrate that if the density of the object is greater than 1 g/cni3, the object sinks. This is demonstrated in the densities of objects 1,2,4,5,6, 9 and 11. Furthermore, if the density of the object is less than 1 g/cm3, the object oats. This is demonstrated in the densities of objects 3,7,8,10, and 12. The presence of a critical value (that is a density of l g/cm3) allows us to predict whether an object sinks or oats. I Pick one of the claims that is not accurate. Use your data to provide a rebuttal to this claim. - An inaccurate claim is the first one, that is, "You can predict whether an object oats or sinks based on its mass." This claim is inaccurate: "You can predict whether an object oats or sinks based on its mass." - Let's consider the masses of objects 3 and 5, that is 4.1 g and 4 g respectively. The object 3 oats While object 5 sinks. Now, let's look at the objects with masses greater than 4.1 g, that is that of object 1 and 8. Object 1 (mass of 19.5 g) sinks while object 2 (mass of 24.2 g) oats. This establishes that there is no critical value of mass that can correctly determine Whether an object will oat or sink. This logic can be extended to any of the mass given in the data. . . +it: Actlwty B: Get the Glzmo read Liquid density - Drag all the objects back onto the shelf. I Check that the Liquid density is still 1.0 glmL. Question: What is the relationship between the object density, the liquid density, and the tendency of the object to oat? . Observe: Place object 1 into the Beaker of liquid. Slowly move the Liquid density slider back and forth. What do you notice? - As object 1 goes into the beaker, the liquid density increases. So did the buoyancy and when the liquid density decreases so does the buoyancy, i'ujuu. - Predict: Buoyancy is the tendency to oat. What is the relationship between the object density, the liquid density, and the tendency of the object to oat? - I learned that if the object density is more than liquid density then the object is immersed. It can also mean if object density is less than liquid density then object oats on liquid - Plan: Write a plan to nd out the answer to a question. Describe the steps you will take to answer the question. - Collect Data: Follow your plan to answer the question. Write your data here. I suggest making a table or chart. I Claim: Write the answer to the investigation question: What is the relationship between the object density, the liquid density, and the tendency of the object to oat? I Evidence: How did the data you collected support your claim? - Reasoning: Based on what you know about density and oating, explain why your claim makes sense
