Mass Volume amp Density Think About It Would you rather kick a bowling ball or a soccer ball Would you rather carry around a kilogram of feathers or a kilogram of lead Explain I Vocabulary . Density: The amount of matter that occupies a certain space.. It is the mass per unit volume of a substance. . What is Density?. Densities of Common Elements and Compounds.  Substance.  Density. grams per mL or cc. The . concentrationof. matter in an object is known as . density. .. Computing Density. . Density = . mass (. g. ) . volume (cm. 3. ). DETERMINE VOLUME. :. One way to determine volume is to use a graduated cylinder to determine . September 7th. DO NOW: . Write a sentence which explains how the terms “senses,” “observations,” and “inferences” relate to each other. Then, make two MORE observations and one inference about the room. Be prepared to share your inference. . Objects that sink . in water are more dense than water. ; objects . that float are less dense.. Learning Goal . . Calculate the density of a substance; use the density to calculate the mass or volume of a substance.. D V. 1. State the formula for density in words and mathematical symbols. Density is mass divided by volume.. D = M/V. 2. . A rock has a mass of 210 grams and occupies a volume of 70 cm3. . What is its density?. In this photo of an oil spill, the oil . i. s floating on the . water. It . floats . because . oil is . lighter than water. . When comparing fluids using the words ‘light’ and ‘heavy’, . you must examine the same volume . Presented by Kesler Science. How do you calculate the density of irregularly shaped objects?. How can calculating density help determine the identity of an unknown substance?. Essential Questions:. Archimedes. Equal Mass and Equal Volume. Density Blocks. In this activity, you will be dealing with nine cubes of different materials and five . cylinders of various sizes and materials. . Make all your measurements first. 1. A piece of tin has a mass of 16.52 g and a volume of 2.26 cm. 3. . What is the density of tin? . Given. Mass= 16.53g Volume 2.26cm. 3. Unknown . D=?. Equation. D=M/V. Sub and Solve. D=16.53g/2.26cm.  . Metric Base Units of Measure.  . Mass = gram (g). Volume = liter . (L). Length = meter (m. ). . Time = second (s).  . Know . your metric prefixes.  . kilo-. Bell Ringer….
