Document Content and Description Below

BIO 100 The Living World Lesson Two BioBeyond Scientific Tools Select all that apply: a. If the mass of the prototype changes then every measurement is now wrong b. There is only one international prototype c. The definition is circular: "one kilogram is a kilogram", and not based on something constant d. A prototype is an early test version of a product, there is no finished kilogram - ✔✔a. If the mass of the prototype changes then every measurement is now wrong c. The definition is circular: "one kilogram is a kilogram", and not based on something constant What about volume, though? You probably know the SI unit for volume already - have a look at the image for a clue. - What is the SI unit for volume? a. A 2-liter bottle of sodaA gallon of milk Gallon b. Liter c. Barrel d. Teaspoon e. Cup - ✔✔b. Liter Which do you think is bigger, a liter or a gallon? The image at right shows a 2-liter bottle and one gallon of milk. a. 1 liter is bigger than 1 gallon b. 1 gallon is bigger than 1 liter c. 1 gallon is the same as 1 liter - ✔✔b. 1 gallon is bigger than 1 liter Part One: To find the volume of this fish tank, you can multiply its length, width, and height. You may have learned V = L x W x H before. This tank has a length of 100 cm, a width of 50 cm, and a height of 50 cm. Multiply those numbers and enter the result in the box below. Part Two: What units would this measurement be in? Just like the numbers, the units get multiplied. cm cmcmcm cm2 cm3 m3 mmm c3m3 - ✔✔Part One: 250000 Part Two: cm3 What is the volume of the fish tank, which was 250,000 cm^3, in milliliters? - ✔✔250,000 milliters 1000 cubic centimeters, or milliliters, is 1 liter. What is the volume of the fish tank in liters? - ✔✔250 liters Think about a cube that is 1 meter on each side. 1 meter is equal to 100 centimeters. So that same cube is 100 cm on each side. What is the volume of such a cube? You can use the same formula as you did for the fish tank, Volume = Length x Width x Height. The L, W, and H of the cube mentioned above are all the same: 100 cm. - ✔✔1,000,000 cm^3 (If the length, width and height of the cube is 100 cm. Calculating the volume is as simple as multiplying the length, width and height. The units will be in cm^3.) So, even though 1 m = 100 cm, how many cubic centimeters (cm^3) are in 1 cubic meter (m^3)? - ✔✔1,000,000 Kilometers ÷ 1.6 = Miles Use that formula to determine just how long a 500 km drive is in miles. - ✔✔312.5 miles What unit would you be in if you took units of centimeters, and multiplied by something that had units of inches divided by centimeters? centimeters+centimeters/inches= - ✔✔inches For example, you're a racing horse in a 4 furlong race. How long is that in miles? How long is that in feet? - ✔✔.5 miles 2640 feet How many nanometers are in 1 meter? - ✔✔1,000,000,000 How many milligrams are in a gram? - ✔✔1,000 How many milligrams are in a kilogram? - ✔✔1,000,000 Convert to scientific notation: 1240 52400000 .00239 .711 - ✔✔1.240x10^3 5.24x10^7 2.39x10^-3 7.11x10^-1 Which of these ph
