Measurement and Density Assessment

Master density, mass, and volume with this engaging science worksheet!

Part 1: Matching Match the unit with the measurement grams mass mL volume g density Fill in the blank with the correct answer. Choose (type in)float orsink. An object with a density of 2 g willsink when placed in a beaker of water. Which of the following would be the best tools to measure the density of a solid block (a rectangle)? a metric ruler and a scale a scale and a thermometer a scale and a barometer a meter stick and a salinity probe The definition ofmassis the amount of matter in a given volume the amount of matter in an object the amount of water in an object To find the volume of an irregular object like a rock, you would use the formula l x w x h water displacement a ruler Given the steps below (which are out of order), the correct order for answering a scientific question is:State QuestionDraw ConclusionHypothesisControlled ExperimentResearch 1, 5, 4, 2, 3 5, 4, 3, 2, 1 3, 5, 1, 2, 4 1, 5, 3, 4, 2 The Density Triangle Using the Density Triangle above, solve this problem:D = 3g M = 6g; V = ?? 0.5mL 2mL 18mL 24mL Volume Question Use the image above to answer the following:A student needs to determine the volume of an irregular object. The original volume of water is 4.8 mL. The student then drops the object into the graduated cylinder and determine the new volume to be 5.6 mL. What is the volume of the object? 4.8 mL 5.6 mL 1.2 mL 0.8 mL A student found the rock shown below and used a digital scale it to determine it's mass. After massing the rock above, what steps should the student take to find its density? determine its volume by how much water it displaces, then divide mass by volume determine its volume by multiplying length x width x height, then divide mass by volume crush the rock to a powder, measure its volume in a graduated cylinder, then divide mass by volume If a wooden block were cut into eight identical pieces, the density of each piece compared to the density of the original block would be less greater the same If two solid objects with the following densities were placed in water, what will happen?Object A - Density = 0.8 g Object B - Density = 1.2 g.cm3 Both objects will sink Both objects will float Object A will float, and Object B will sink Object B will float, and Object A will sink Hot air rises because it is more dense than cool air it is as dense as cool air it is less dense that cool air Use the Density Triangle found earlier in this assessment to help you answer this question:If an object's density is 3 g and it displaces 3 mL of water, what is its mass? 1 g 3 g 9 g A dependent variable is the "I change" variable the variable you measure or record the variable that always stays the same You have 2 pieces of silver. Piece one has a mass of 5 g, and piece 2 has a mass of 10 g. Which is more dense? Piece 1 Piece 2 They are the same There is no way to tell Use the density triangle to help answer this question:If the density of a sample is 14 g and its mass is 56 g, its volume is - 0.25 mL 4 mL 42 mL 14 mL To best verify the observed results in an experiment, which of the following should be done? test multiple variables at one time write down all observations during the experiment repeat the experiment Read the following passage and answer the questions below: Click on the blank, then choose your answer from those listed. Smithers thinks that a special juice will increase the productivity of workers. He creates two groups of 50 workers each and assigns each group the same task (staple a set of papers). Group A is given the special juice to drink while they work. Group B is not given the special juice. After and hour, Smithers counts how many stacks of papers each group has made. Group a made 1,587 stacks, Group B made 2,113 stacks.Identify the:a. control group: Group Bb. independent variable: Special juicec. dependent variable: stacks Predict whether the following items will sink or float in fresh water. Click on each item, then choose sink or float to place it in the correct column. SINK gold 19.3 g corn syrup 1.38 g FLOAT ice .92 g corn oil .93 g wood .85 g
