  1. Daily Thinker 10/04/10 Task: BE QUIET, WRITE AGENDA FIRST! What are the goals you have set for yourself this week? Explain them. If you do not yet have any goals, set at least one.

  2. Daily Thinker 10/5/10 Define in your own words: • Mass • Weight • Matter • Gravity BE READY TO TAKE NOTES NEXT!

  3. Matter • Anything in the universe that takes up space • Anything that has mass • Anything that is made of atoms and molecules

  4. Gravity • An attractive force that pulls objects together • Example: Earth’s gravity keeps objects on the surface by pulling objects toward the center • Everything in the Universe has gravity (even people!) • Depends on the mass of an object • The greater the mass the greater the gravitational pull

  5. Weight • The force on an object caused by gravity trying to pull the object down • A spring scale measures the force of gravity pulling on a mass • A person with more mass has more gravity, and therefore weighs more.

  6. Mass • How much matter an object contains • Measured using a balance • Basic unit of measure is the gram • consistent, not dependent on gravity http://www.exploratorium.edu/ronh/weight/

  7. Daily Thinker 10/6/10 • Explain what measurement means. • Give 3-5 careers you think use measurement the most. • Write as many words that relate to measurement as you can.

  8. Daily Thinker 10/06/10 • List as many words that you can think of relating to measurement.

  9. Lesson 1: Length

  10. 1 mile 1.6 kilometers 1 yard = 0.9444 meters 1 inch = 2.54 centimeters English vs. Metric Units Which is longer? A. 1 mile or 1 kilometer B. 1 yard or 1 meter C. 1 inch or 1 centimeter

  11. A. 1 meter or 105 centimeters B. 4 kilometers or 4400 meters C. 12 centimeters or 102 millimeters D. 1200 millimeters or 1 meter km Metric Units m cm mm The basic unit of length in the metric system in the meter and is represented by a lowercase m. Standard: The distance traveled by light in absolute vacuum in 1⁄299,792,458 of a second. Metric Units 1 Kilometer (km) = 1000 meters 1 Meter = 100 Centimeters (cm) 1 Meter = 1000 Millimeters (mm) Click the image to watch a short video about the meter. Which is larger?

  12. 1 centimeter = 10 millimeters What is the length of the line in centimeters? _______cm What is the length of the line in millimeters? _______mm What is the length of the line to the nearest centimeter? ________cm HINT: Round to the nearest centimeter – no decimals. Measuring Length How many millimeters are in 1 centimeter?

  13. Daily Thinker 10/07/10 DO NOT TOUCH THINGS WITHOUT PERMISSION! Fill in the blanks. Use your notes. • ____ is how much ______ an object contains. • A triple beam balance is used to measure___. • The basic unit of measuring mass is _______. • _______ changes with gravity while _______ will remain constant even if gravity changes. Interactive Balance Beam

  14. Lesson 2: Mass

  15. 1 pound = 453.6 grams 1 ounce of gold = 28,349.5 milligrams 100 kilogram = 220 pounds English vs. Metric Units Which is larger? 1. 1 Pound or 100 Grams 2. 1 Kilogram or 1 Pound 3. 1 Ounce or 1000 Milligrams

  16. Kilogram Prototype A. 1 kilogram or 1500 grams B. 1200 milligrams or 1 gram C. 12 milligrams or 12 kilograms D. 4 kilograms or 4500 grams kg Metric Units cg mg g Mass refers to the amount of matter in an object. The base unit of mass in the metric system in the gramand is represented by g. Standard: 1 kilogram is equal to the mass of the International Prototype Kilogram (IPK), a platinum-iridium cylinder kept by the BIPM at Sèvres, France. Metric Units 1 Kilogram (km) = 1000 Grams (g) 1 Gram (g) = 1000 Milligrams (mg) Click the image to watch a short video about mass. Which is larger?

  17. 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 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.

  18. 1st – Place the film canister on the scale. 2nd – Slide the large weight to the right until the arm drops below the line. Move the rider back one groove. Make sure it “locks” into place. 3rd – Repeat this process with the top weight. When the arm moves below the line, back it up one groove. 4th – Slide the small weight on the front beam until the lines match up. Measuring Mass – Triple-Beam Balance 5th – Add the amounts on each beam to find the total mass to the nearest tenth of a gram. Interactive Balance Beam
