___________________________________________________________________________________

___________________________________________________________________________________

5. For how many days did you record the same temperature?
6. If you added together the temperatures for the three warmest days, what would you get? (You may use a calculator).
7. At what temperature does water boil? _______________________________

8. At what temperature does water freeze? _____________________________

Worksheet #2
The Beaufort Wind Scale

BEAUFORT NUMBER KM/H MPH DESCRIPTION

0 less than 1 calm; smoke rises vertically

1 1-5 1-3 light air: not enough to move a wind vane, but shows in smoke drift

2 6-11 4-7 light breeze: wind felt on face, leaves rustle, wind vanes moved by wind

3 12-19 8-12 gentle breeze: leaves and small twigs in constant motion, enough to blow a light flag

4 20-29 13-18 moderate: raises dust and loose paper, moves small branches

5 30-39 19-24 fresh: small trees in leaf begin to sway, crested wavelets form on inland waters

6 40-50 25-31 strong: large branches move, umbrellas used with difficulty

7 51-61 32-38 near gale: whole trees in motion, inconvenience in walking against the wind

8 62-74 39-46 gale: wind breaks twigs off trees, making walking difficult

9 75-87 47-54 strong gale: slight damage occurs to building structures

10 88-102 55-63 storm: trees uprooted, considerable damage

11 103-121 64-72 violent storm: widespread damage

12 over 122 over 73 hurricane
