**So why do you think scientists use SI?**

Turn to your table partner and discuss. Be prepared to share!

5
So how does SI work? Take a base/unit, depending upon what is being measured Add an appropriate prefix

6
**Units/bases For ………………….use Length meter (m) Mass gram (g)**

Volume liter (L) Time second (s) Temperature Celsius (C)

7
**Prefixes Kilo (k) 1000 hecto (h) 100 deka (da) 10 (unit or base) 1**

deci (d) centi (c) milli (m) So…how can you remember this?
