Name Period Test on Size and Scale from the Electron to the Galaxies 1-3 If our room is 30 feet long and 30 feet wide and 9 feet high then what is the area of the room? 2-5 What is the volume of the room? 6-8 If there are 7.5 gallons in a cubic foot how many gallons of water would fill the room(to nearest gallon)(NO CALCULATORS) Distances Distances are one dimensional measurements. Distances are often measurements between two points in space or distances can be a measurement of the length, width or height of an object. American-English 9 How many inches in a foot? 10 How many feet in a yard? Inches in yd? 11 How many feet in a mile? Yards in a mile? 12 How many miles from Los Angeles California to Washington DC? 13 How many miles around the equator? 14 How many miles to the moon? 15 How many miles to the Sun? 16 What is that distance called? 17 What is the definition of a light year? 18 How far is a light year in miles? 19 Is a light year the distance from the Sun to the earth? 20 The closest star we see at night is Proxima Centauri. It is 4 light years away. How many miles away is that star? 21 The stars we see in the night sky are all from our galaxy-the Milky Way. The farthest object in the night sky is a smudge of light from our neighboring galaxy—the Andromeda Galaxy. Is our neighboring galaxy 2.5 light years away or 2.5 million light years away? Is a light year a distance or a time? The average depth of the oceans , the depth in the earth where the temperature would cause water to boil-100C and the distance from River Hills Mall to LCS are all about the same . How many miles(nearest half mile) The deepest hole in the earth is 7.5 miles dug in Russia. The deepest natural point on earth is in the oceans 6.8 miles . Where is that place and what is the geological form? The highest point on Earth is 29,500 feet(5.5 miles) Where is that and what is the land form. How deep is it to the center of the earth? CONVERSIONS SI(Systeme Internationale)-American 26 Is a meter closer to a foot (a ruler) or a yardstick? 27 What is a yard stick and a meter stick in inches? 28 How many centimeters in an inch? 29 A kilometer is a 1000 meters. Is a kilometer larger or smaller than a mile? 30 One hundred(100) kilometers is how many miles? A 5K race is how many miles? Distances(SI) 31- 42 Use word(or abbreviation) and scientific notation so two answers for each question Divide a meter stick into a hundred units. What measurement do you have? A meter divided by 1000 is a A meter divided by a million is the size of a bacteria cell. A meter divided by a billion is the size of a cell membrane. A meter divided by 10 billion is the diameter of an atom. 41-42 A meter divided by a 1000 trillion is the diameter of the nucleus of an atom. Areas(43-55) Areas are two dimensional surfaces How many square inches in a square foot? How many square feet in a square yard? Draw a diagram showing a square mile. What is a square mile called in surveying? How many acres in a square mile? Divide your square mile to show 320, 160 and 40 acres. Draw a football field and show how much is covered by an acre. A hectare is how many square meters? Conversions How many acres in a hectare? Areas and Standard Shapes. Draw the shape, And show formula for calculating the area. (57-65) Square Rectangle Triangle Circle Volumes(66-74) Volumes are three dimensional measurements How many teaspoons in a tablespoon? How many tablespoons in an ounce? Tablespoons in a cup Ounces in a cup Cups in a pint Pints in a quart Ounces in a quart Quarts in a gallon SI(75-78) One cubic centimeter-one cc= 10cmx10cmx10cm= 1000cubic centimeters= 1000ml= SI( Metric) from/to English(American) Conversions(79-83) 1 tsp= ml 1 oz = ml 500 ml = 1 liter = oz quarts Common Three dimensional Shapes (Volumes and Surface Areas) The volume is a three dimensional unit expressing how much space is taken up. The surface area is the area of needed to completely cover the outer surface of the shape. (84-100) Volume Sphere Cylinder Surface Area Cube Rectangle Mass(101-105) 1 cc of water = 1 liter of water = Conversions SI to American One kilogram =(in pounds)= 70kg man =(in pounds)= 454 grams= Match the mass a)One electron b)One proton=one neutron=one atomic mass unit=one Dalton= c)Mass of the Earth d)Mass of the Sun e)One ml of water f) One liter of water g)Mass of the universe 106 One gram--------107 6x1024 kg-----------108 1.99x1031kg-----------109 1.99x10-27kg------------110 One kilogram------------111 9.1x10-31kg---------------EXTRA 1050 kg----------------- Density(112-115) What is Density-(formula) What is the density of water in gm/cc Density of the Sun (gm/cc) = Density of the Earth(gm/cc)= Scientific Notation (write the number as a word if you know it and the number in scientific notation) Two answers each question.(116-142) 10x10= 10x10x10= 1000 X 1000= 1000 X million= 1000 X billion= Write in scientific notation One divided by 100= One divided by 1000= One divided by a million= One divided by a trillion= Is a negative exponent a negative number? Explain what a negative exponent means. How do you write one in SN How do you write ten in SN. Put these wrenches in order from smallest to largest(use letters)(143-146) a) 3/16 b) 3/4 c) 7/16 d) 1/2 ------------------------------------------------------------ e) 3/8 f) 9/16 147-150 What are these distances and speeds in both miles and kilometers.( Extra credit if given in both measurement systems) Distance between Earth and Sun Distance of a Light Year Speed of Light Speed of Sound
