UNLOCKING OF DIFFICULTIES

What is moving air?

MOTIVATION:

How does the wind

blows?

MOTIVATION:

WIND SPEED WIND EFFECTS ON TREECalm Leaves remain still.Light Leaves rustle.

Gentle Leaves & small twigs move.Moderate Small branches move.

Strong Large branches move.Gale Twigs break off.

Time Wind Speed Proof8:00 a.m.    

12:00 noon    3:00 p.m.    

ACTIVITY 1OBSERVING WIND SPEED

1.Observe how fast the wind moves in your area in the morning (8:00 a.m.) at noon (12:00) & in the afternoon (4:00 p.m.).2.Use particular trees as your reference point to describe how the wind blows.3.Use the table below as your guide in observing wind speed.4.Record your observation using the chart below:

a. Does wind speed change from time to time during the day?b. During what weather do winds move gently? Strongly? c. Relate the speed of the wind to weather conditions for the day

Date Wind Direction Sky Condition                         

ACTIVITY NO.2DETERMINING WIND DIRECTION

1.Using the wind vane that you made, record the direction of the wind at 8:00 a.m. everyday for one week. 2.Use the following table:

a. How the wind does blows from day to day? Why do you think so?

b. Describe the condition of the sky in relation to wind direction.

c. Relate wind directions to sky conditions

Group Reporting & Discussion

Generalization:

How do we measure the speed & direction of the wind?

Science Concept:• Wind speed & direction may change

from time to time throughout the day.

• The anemometer & the wind vane are instruments used to measure wind speed & direction respectively.

• Sky condition is influenced by wind speed & direction.

Application:• Wind speed & direction for the

day is much predictable, what will you do? Why?

• What will do when you notice that the wind is always strong to very strong in the afternoon? Why?

Valuing:

Why is weather forecast important? Why?

EVALUATIONDirection: Select the letter of the best answer.1. Wind speed refers to __________

A. the temperature for the dayB. the availability of the windC. amount of moisture in the airD. how fast or how slow the wind blows

2. How can weatherman determine the speed of the wind?A. They use compass.B. They use barometer.C. They use anemometer.D. They use thermometer.

3. A ______________ tells the direction from which the wind is blowing? A. meter stick

B. wind vaneC. anemometerD. weighing scale

4. A wind that is blowing to the west is a ______________?A. west windB. east windC. north windD. south wind

5. How does the wind blow?A. from a warm place to a cold placeB. from a cold place to a warm placeC. from a cold place to another cold placeD. from a warm place to another warm place
