Measuring Matter Tree Map To review Volume, Mass, and Density, create a tree map for measuring matter on a piece of notebook paper. For each type of measurement, include a definition, ways to measure it, examples, pictures, etc.

MEASURING MATTER DENSITY VOLUME MASS

MEASURING MATTER VOLUME DENSITY MASS How much space something takes up Formula  L x W x H Water displacement Examples – 5 mL, 2 cm3 How much matter (stuff) there is in an object Measured on a triple beam balance Examples – 3 g, 10 kg How tightly packed particles (atoms) are in a substance Mass per unit of volume Formula  D = M/V Examples – 1 g/mL, 2 g/cm3

Measuring Liquid Volume What is the volume of water in each cylinder? Images created at http://www.standards.dfes.gov.uk/primaryframework/downloads/SWF/measuring_cylinder.swf A B C Pay attention to the scales for each cylinder.

Measuring Solid Volume 10 cm 9 cm 8 cm We can measure the volume of regular object using the formula length x width x height. _____ X _____ X _____ = _____ http://resources.edb.gov.hk/~s1sci/R_S1Science/sp/en/syllabus/unit14/new/testingmain1.htm We can measure the volume of irregular object using water displacement. Amount of H2O with object = ______ Amout of H2O without object = ______ Difference = Volume = ______ Click here for an online activity about volume. Choose Lessons  Volume & Displacement

_______ + ______ + _______ = ________ g Measuring Mass We will be using triple-beam balances to find the mass of various objects. The objects are placed on the scale and then you move the weights on the beams until you get the lines on the right-side of the scale to match up. Once you have balanced the scale, you add up the amounts on each beam to find the total mass. What would be the mass of the object measured in the picture? _______ + ______ + _______ = ________ g Top Image: http://www.southwestscales.com/Ohaus_Triple_Beam_750-SO.jpg Bottom Image: http://www.regentsprep.org/Regents/biology/units/laboratory/graphics/triplebeambalance.jpg

Density Calculations Use the formula Density=Mass/Volume to calculate the density of the following objects! Also indicate if these objects will sink, float, or suspend in water. Mass= 45g ; Volume= 9cm3 Mass= 25g; Volume= 50mL Mass= 60g; Volume= 20mL Mass=12g; Volume= 3cm3 Mass= 15g; Volume=15cm3

Liquid Density Column Place the following liquids in order with the smallest density at the top of your list, and the largest at the bottom. Rubbing alcohol Water Corn syrup Lamp oil Dish soap Vegetable oil
