### Transcript of "Metrics/Measurement"

1. 1. LENGTH LAB
2. 2. How Many Thumbs <ul><li>Measure the HEIGHT of your LENGTH LAB sheet of paper. </li></ul><ul><li>Write down how many thumbs it took on the BACK OF YOUR PAPER </li></ul><ul><li>Ask your partner how many thumbs? Do you get the same answer? Why or why not? EXPLAIN ON THE BACK OF YOUR PAPER </li></ul>
3. 3. <ul><li>Science make two types of observations. We learned </li></ul><ul><li>that they are _______________ and </li></ul><ul><li>_________________. Because we can’t always trust </li></ul><ul><li>our eyes, it is best to always use </li></ul><ul><li>____________________ which uses numbers. In </li></ul><ul><li>science class, we will be using the ____________ </li></ul><ul><li>system to to take the length, volume, mass, and </li></ul><ul><li>temperature of different objects. This system is easy </li></ul><ul><li>because it is based on the number ___________ </li></ul>QUAN QUAL QUAN METRIC 10 BACKGROUND INFO 38
4. 4. BACKGROUND INFORMATION The distance from one point to another. METERS LENGTH WHAT DO I MEASURE DEFINITION UNITS TOOL m
5. 5. <ul><li>KILOMETERS </li></ul><ul><li>METER </li></ul>CENTIMETER MILLIMETER NOTES: HOW BIG IS IT??
6. 6. <ul><li>Measure these lines using a metric ruler! </li></ul><ul><li>Write your measurement next to the line. </li></ul><ul><li>Remember to include the unit as part of the measurement. Without units, numbers are meaningless. THEY NEED A LAST NAME!! </li></ul>PRACTICE TIME
7. 7. <ul><li>TAKE OUT YOUR LENGTH LAB </li></ul><ul><ul><li>- Measure the lines on 1-5 </li></ul></ul><ul><ul><li>-Complete the Using Your Noggin Box </li></ul></ul><ul><li>Get out COLORS: green, yellow, red </li></ul><ul><li>Graph your grades </li></ul><ul><li>Get ready for NOTEBOOK CHECK </li></ul>WARMUP DO NOT WRITE JUST FOLLOW THE DIRECTIONS 39
8. 8. 3.9 cm 7.8 cm 1 cm 5.1 cm 3.5 cm PRACTICE TIME: CHECK YOUR ANSWERS
9. 9. a. The distance from city to city km m cm mm b. The height of a flagpole km m cm mm c. The length of a lady bug km m cm mm d. The length of a pencil km m cm mm USING YOUR NOGGIN'
10. 10. SUMMARY What did you learn about in our length lab <ul><li>Was measuring in METRIC (meters) better than using USA (inches), </li></ul><ul><li>WHY DO WE NEED TO HAVE EXACT MEASUREMENT (remember How many thumbs) </li></ul>
11. 11. Objective: I will review length and complete my lab and practice another measurement called volume <ul><li>WARMUP #9 </li></ul><ul><li>FILL IN THE BLANKS </li></ul><ul><li>METER LENGTH METRIC ENGLISH </li></ul><ul><li>In science class, we use the ______________ system. __________ is the distance from one point to another. The metric unit for length is _________. </li></ul><ul><li>2 The best unit to use if we were measuring the length of a battery is km m cm mm </li></ul>Length Metric meter 39
12. 12. SCAVENGER HUNT TIME <ul><li>USE YOUR 2 LEVEL VOICES </li></ul><ul><li>Work with your team </li></ul><ul><li>Everyone participates </li></ul><ul><li>Remember numbers need a LAST NAME </li></ul><ul><li>GROUP ROLES </li></ul><ul><ul><li>GROUP LEADER: focused and working well </li></ul></ul><ul><ul><li>VOICE MONITOR: 2 level </li></ul></ul><ul><ul><li>TIME KEEPER: 15 minutes </li></ul></ul><ul><ul><li>LENGTH WIZARD: DOUBLE CHECKS answers </li></ul></ul>
13. 13. SUMMARY What did you learn about in our length lab <ul><li>Was measuring in METRIC (meters) better than using USA (inches), </li></ul><ul><li>WHY DO WE NEED TO HAVE EXACT MEASUREMENT (remember How many thumbs) </li></ul>
14. 14. METRIC GRAPHIC ORGANIZER is the amount of _________ an object takes up liters VOLUME WHAT DO I MEASURE DEFINITION UNITS TOOL l = cm 3 space 38
15. 15. <ul><li>Add liquid to the graduated cylinder </li></ul><ul><li>Get eye level with the liquid in the graduated cylinder </li></ul><ul><li>Read the BOTTOM of the MENISCUS </li></ul><ul><li>Determine how much liquid is in the graduated cylinder </li></ul>VOLUME: A, B, C
16. 16. IRREGULAR SHAPED OBJECT <ul><li>Fill a graduated cylinder with a certain amount of water </li></ul><ul><li>Write down the STARTING amount </li></ul><ul><li>Add the object and note how much the water went up in the cylinder. This is the ENDING amount </li></ul><ul><li>Subtract the ENDING-STARTING amount. This equals the VOLUME OF THE OBJECT </li></ul>Water Displacement (12 ml) (20 ml) 20-12 = 8 ml
17. 17. NOTES TWO TYPES OF VOLUME L H W Regular Irregular V=L x W x H
18. 18. REGULAR SHAPED OBJECT <ul><li>Measure the LENGTH (L) </li></ul><ul><li>Measure the WIDTH (W) </li></ul><ul><li>Measure the HEIGHT (H) </li></ul><ul><li>Multiply L x W x H= VOLUME </li></ul><ul><li>Remember numbers need a LAST NAME !! (cm 3 ) </li></ul><ul><li>3 cm x 3 cm x 3 cm = 27 cm 3 </li></ul>L W H
19. 19. Objective: I will practice finding the volume of regular and irregular objects <ul><li>WARMUP #10 </li></ul><ul><li>FILL IN THE BLANKS </li></ul><ul><li>liter volume graduate cylinder </li></ul><ul><li>__________ is how much space an object takes up In science class, we use a ___________________ to measure volume. The unit for volume is _________ </li></ul><ul><li>Draw a box that is L=6, H=3, and W=3. What is the volume. </li></ul>Graduated Cylinder Volume liter 54 cm 3 41
20. 20. Regular Object <ul><li>Can you find the volume of this box?? </li></ul>6 cm 3 cm 3 cm V = L X W X H L W H V = 6 cm x 3 cm x 3 cm = 54 cm 3
