1. Today’s Learning Goal:

2.  What is the basic unit for measuring liquids?  The liter  There are 3 larger units and 3 smaller units, what are there prefixes?  Kilo-, hecto-, deca-, and deci-, centi-, and milli-  King Henry Died by Drinking Chocolate Milk

3.  Volume - The amount of space matter takes up.  Graduates – The marked and unmarked lines on the graduated cylinder  Meniscus -The bottom of the U-shaped curve of a liquid in a graduated cylinder

4. When finding the volume, bend down so the graduated cylinder is at eye level. Then read the graduate at the bottom of the curve. meniscus

5. Get down at eye level to read meniscus

6. 500 400 300 200 100 To find the volume in a graduated cylinder you need to know three important pieces of information: You must determine (1) how the scale is increasing with each graduate, (2)where you should measure from, (3)and what metric unit to use for the measurement. Scale increases by 10ml Measure from the meniscus at eye level Use the metric unit, ml

7. 500 400 300 200 100 Measure from here, The bottom of the meniscus is the standard point of measurement. Never measure from the top of the meniscus

8. 500 400 300 200 100 What do each of the graduates represent? How do you know? How much water is in this graduated cylinder? 350 mL 10 mL

9. 50 40 30 20 10 What are each of the graduates equal to? How do you know? 1 mL How much liquid is in this graduated cylinder? 47 mL

10. 5 4 3 2 1 What are each of the graduates equal to? How do you know? 0.1 mL How much liquid is in this graduated cylinder? 1.3 mL

11. 25 20 15 10 5 What are each of the graduates equal to? How do you know? 0.5 mL How much liquid is in this graduated cylinder? 16.5 mL

12. 10 8 6 4 2 What are each of the graduates equal to? How do you know? 0.2 mL How much liquid is in this graduated cylinder? 8.4 mL

13. 5000 4000 3000 2000 1000 What are each of the graduates equal to? How do you know? 100 mL How much liquid is in this graduated cylinder? About 4550 mL

14. 2500 2000 1500 1000 500 What are each of the markings equal to? 50 mL How much liquid is in this graduated cylinder? 1350 mL

15. What is this reading? 18.0 mL

16. What is this reading? 36.5 mL

17. What is this reading? 73 mL

18. Understanding the scale: Read and record the liquid volumes. Don’t Forget your units. EXIT SLIP A. B.C.
