Metrics and Measurement Science Skills Unit Metric Mania
AREA Area • Definition: Amount of two-dimensional space an object takes up. • Units: meters squared– m2 • Tools Used: metric ruler
AREA area = length x height
AREA area = length x height Find the area of the squares below. 100 cm2 150 cm2 10 cm 20 cm 15 cm 5 cm
VOLUME Volume • Definition: Amount of space an object takes up. • Units: meters cubed – m3 or liters • Tools Used: Regular solid – metric ruler Irregular solid – water displacement Liquid – graduated cylinder
VOLUME – Regular Solid volume = length x width x height Find the volume of the blocks below. 80 cm3 320 cm3 10 cm 8 cm 4 cm 2 cm 10 cm 4 cm
LIQUID VOLUME Read the measurement from eye-leveland from the bottom of the meniscus (curve made by the water). Top Image: http://www.tea.state.tx.us/student.assessment/resources/online/2006/grade8/science/images/20graphicaa.gif
LIQUID VOLUME What is the volume of water in each cylinder? (Units are milliliters.) 52 mL 37 mL 23 mL Images created at http://www.standards.dfes.gov.uk/primaryframework/downloads/SWF/measuring_cylinder.swf Pay attention to the scales for each cylinder.
VOLUME of IRREGULAR SOLIDS We can measure the volume of irregular objects using water displacement. Volume of Irregular Solids Volume of Water & Object Volume of Water – =
VOLUME of IRREGULAR SOLIDS Amount of H2O with object = ______About of H2O without object = ______Difference = Volume = ______ 260mL 200mL http://resources.edb.gov.hk/~s1sci/R_S1Science/sp/en/syllabus/unit14/new/testingmain1.htm 60 mL
