1. L.O: REVIEW MEASURING
TEMPERATURE, AIR
PRESSURE, DEWPOINT,
HUMIDITY, LENGTH AND
DENSITY.

2. A MEASUREMENT USES
NUMBERS TO DESCRIBE
PROPERTIES OF OBJECTS.
EX: LENGTH, TEMPERATURE, AIR PRESSURE,
DEWPOINT AND HUMIDITY ARE SOME MEASURABLE
QUANTITIES

3. INSTRUMENTS ARE USED TO MEASURE
THE QUANTITIES OF PROPERTIES OF
OBJECTS.
I MUST KNOW THE FOLLOWING INSTRUMENTS AND
WHAT THEY MEASURE:

4. THERMOMETER MEASURES TEMPERATURE
IN CELSIUS, FAHRENHIET AND KELVIN
ESRT PAGE 13 SHOWS HOW TO
FAHEHRENHEIT, CELSIUS AND KELVIN
INTO EACH OTHER.

5. NOW COMPLETE TYPICAL
TEMPERATURE QUESTIONS
ON WORKBOOK PAGE 142-
143

6. BAROMETER measures air pressure in
MILLIBARS (mb) and INCHES OF hg. (inches
of mercury)

7. On the regents, I might be asked to draw
ISOBARS. ISOBARS: connect points with
equal pressure readings.

8. On the regents, I might be asked to draw
ISOBARS. ISOBARS: connect points with
equal pressure readings.

9. Winds are caused by pressure differences.
Winds flow from high pressure to low
HIGH PRESSURE

10. Surface winds are most likely blowing
from
• a. Danbury toward New
York City
• b. Poughkeepsie toward
Scranton
• c. Binghamton toward
Danbury
• d. Port Jervis toward
Binghamton

11. ISOBARS are always drawn in intervals of 4
millibars: 1000, 1004, 1008, 1012, 1016….

12. ISOBARS are always drawn in intervals of 4
millibars: 1000, 1004, 1008, 1012, 1016….

13. STRONGEST WINDS ARE WEAR
ISOBARS ARE CLOSE TOGETHER.

14. WHERE IS THE STRONGEST WINDS?
•A
•B
•C
•D

15. ESRT page 13 can be used for air
pressure questions.

16. Read page 145.
complete typical air pressure
questions.

17. PSYCHROMETERS: measure dewpoint and
humidity.

18. PSYCHROMETERS are made of two
thermometers: a “wet bulb” and a “dry
bulb”.

19. 1st: one finds the difference between the
“wet bulb” and “dry bulb”. 2nd: one uses
one of the charts on ESRT page 13.

20. Now some typical dewpoint/
relative humidity (psychrometer)
questions page 131- page 141

21. ANONEMETER MEASURES WIND SPEED.
WIND VANE MEASURES WIND DIRECTION.

22. LENGTH
Complete page 16-17 in workbook.

23. DENSITY
Complete page 38- 40 in workbook.

24. WATER IS WEIRD.
For all other substances, the solid phases is the
densest.
WATER IS DENSEST AT 4 DEGREES CELSIUS.
