QUEST CHECK 10-12 Please number your paper #1-4. You may NOT use your notes!

QUEST CHECK 10-12 Make the following conversions: 59.8 hm = ____ km 9.8 mg = ____ dg 35 g = ____ cg 4033 liters= ____ kiloliters

QUEST CHECK 10-12 Make the following conversions: 59.8 hm = 5.98 km 9.8 mg = 0.098 dg 35 g = 3500 cg 4033 liters= 4.033 kiloliters

Why is the Metric System better? Conversions are MUCH EASIER! Everything is based on ten, so you just need to move the decimal! LETS PRACTICE!

Rules to Convert with Metric Rewrite the number exactly as it appears LIGHTLY put in the decimal point where it currently belongs Find the current unit symbol in the chart above and count the number of spaces to the new unit symbol, noting if your movement is to the right or to the left. Place your pencil on the lightly marked decimal point and count the number of spaces determined from step 3 either to the left or right, creating little egg crates” under each number Mark a DARK, BIG decimal point at the new space If there are any “empty egg crates”, fill them with zeroes.

Q #9-13: Precision vs. Accuracy Accuracy- how close a value is to the true or accepted value. Precision- how close a group of measurements are to one another.

Mass Questions #21-23 21. Mass is the measure of the amount of matter in an object. 22. Kilogram is the SI Basic Unit for mass. Gram is the METRIC Base unit for mass. Weight is the measure of the force of GRAVITY on an object. Weight would change if you went to the moon (the moon has 1/6 the gravity of Earth), but your mass would stay the same!

Mass Question #24- Steps to use a Balance Place the balance on a flat/level surface. Make sure all riders are moved to ZERO. Make sure the balance is calibrated (the lines match up). Place the object on the pan and allow it to settle. Move the LARGEST rider first. Stop when the lever hits the bottom and move the rider back ONE notch. Repeat step 6 with all riders, going from largest to smallest. Your goal is to move the riders until the two lines match up. Add up all of the positions where you put the riders to find the mass of the object in the pan. Remember to guess one decimal place and DON’T FORGET UNITS!!

Question #25 0 + 40 + 5.80 = 45.80g 500 + 30 + 8.91 = 538.91g

Record the Following Data Year of Penny Work Space (Show your work to add up each beam on the balance) Mass of Penny (Don’t forget UNITS!)

History of the Penny http://www.cozziobrien.com/the-copper-pennys-composition-a-brief-history/

Timeline of the Penny 1909-1982 1982-present day 95% copper 5% zinc (exception= 1943 penny was steel coated with zinc due to a copper shortage during World War II) 1982-present day 97.5% zinc 2.5% copper

How to tell what a penny is made of: Look at the year. If it was minted from 1864 to 1982, then it is 95% copper. If it was minted after 1982, then it is 97.5% zinc. Older 1982 pennies are 95% copper, while newer 1982 pennies are 97.5% zinc. Be aware that some 1983 pennies are 95% copper. Drop the penny on a hard surface. If the dropping sound is loud, the penny is 95% copper. Otherwise, the penny is 97.5% zinc. If the sound has a high pitched ring, it is mostly copper. Measure the penny. Use a scale like the ones used for measuring gold to measure the penny. If it is 2.5 grams, then the penny is 97.5% zinc. If the penny is 3.1 or 3.2 grams, then the penny is 95% copper.

Time and Temperature 10/27 42. Time is the duration of an event. 43. The SECOND is the unit to measure time. 44. A clock, watch, or stopwatch is used to measure time. 45. Temperature is the amount of heat in an object. 46. The KELVIN (K) is the SI base unit for temperature… BUT Scientists use Celsius MOST in the lab!! 47. The thermometer is used to measure temperature.
