Finding practical applications of concepts and skills in daily living

A strong typhoon hits your nearby barangay. Many people were homeless and stayed in the evacuation center. How can you help them? What will you do?

Making generalizations and abstractions about the lesson

What are the effects of typhoon in the community?

Typhoon cause so much damage in a place because it brings with it strong winds, heavy rains, storm surges and tornadoes. Typhoons usually cause floods, which greatly cause a lot of danger and damage such as destroying crops, destroying buildings, killing people and other living things

Oil spills can result when strong waves and winds brought about by typhoons damage the oil platforms. Oil spill can cause death in marine life such as fish kill.

Storm surge may occur along the coastal similar to what happened in Tacloban, Leyte during Typhoon Yolanda in 2013.

Fish farms or cages in some parts of the country are also by the storm. Boats capsize and ships may overturn and sink when huge waves hit them.

Fish farms or cages in some part are also affected when there is a typhoon. Millions of pesos are lost as strong typhoons can destroy facilities, equipment and products from fish farms.

The lives of fishermen who happen to go out to sea to catch fish are endangered when caught.

Typhoon, however, have positive outcomes too. Typhoons bring abundant fresh water, though this may mean floods. Dams are easily filled up by heavy rains that accompany a typhoon, which replenishes most of the country’s water supply.

Evaluating learning

Check /s the letter that describes the effects of typhoon.

__a. The farmers crop get destroyed when there are heavy rains which result to flooding.

__b. Loss of lives and damage to properties happen due to flooding and landslides

__c. Thousands of families become homeless

__d. Fisherman can go fishing and abundant catch awaits them.

__e. Power supply is cut off for several days as falling trees destroy the electric posts and power lines

__f. People lose their homes and means of livelihood.

__g. Prices of basic commodities become cheaper.

Additional activities for application or remediation

The Philippines is often visited by typhoons. Use your imagination and creativity to design something which you can use during or after a typhoon. Then write few sentences to discuss your purpose for inventing such thing and what your thing can do.

You heard from the news that there is a typhoon that will enter the

Philippine Area of Responsibility and Public storm Signal Number 3 is

raised on your barangay. What will you do?

Why?

How will you prepare for it?

Making generalizations and abstractions about the lesson

What are the different storm signals?

Typhoon signals are raised when wind speed is very strong. Wind strength determines typhoon signals. Philippines Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) is a government agency that issue warnings to people.

Typhoon signals warn people of the coming typhoon through their regular weather bulletins.

Wind speed is expressed in kilometers per hour (Kph) and wind speed is measured by the use of an anemometer.

Typhoon Signal Meaning

Number 1

Weather disturbance is within the Philippine Area of Responsibility. Winds are up to 60 km per hour may be expected in the locality within the next 36 hours.

Classes are suspended in the nursery, kindergarten and pre – school levels.

Number 2

Weather disturbance is affecting the locality. Winds of 60 to 100 km per hour are expected within the next 24 hours. Houses of light materials should be strengthened.

Classes in elementary and secondary levels are automatically suspended.

Number 3

Weather disturbances are dangerous to the locality. Winds of more than 100 km per hour are expected within the next 12 to 18 hours. Classes are suspended in all levels and people are advised to stay indoors. Seas will be very rough

Number 3

Weather disturbances are dangerous to the locality. Winds of more than 100 km per hour are expected within the next 12 to 18 hours. Classes are suspended in all levels and people are advised to stay indoors. Seas will be very rough

Evaluating learning

Label the description below to enumerate the different storm signal.

______ 1.Winds of 60 to 100 km per hour are expected within the next 24 hours.

______ 2. A super typhoon is expected in the locality with wind speeds of 200 km per hour or more

_____ 3. Winds is up to 60 km per hour may be expected in the locality within the next 36 hours.

______ 4. Winds of more than 100 km per hour are expected within the next 12 to 18 hours. Classes are suspended in all levels and people are advised to stay indoors

Additional activities for application or remediation

Describe and classify two or more powerful storms that occurred in the area where you live. Include the storm signals of these typhoons. How much damage did they cause?

Finding practical applications of concepts and skills in daily living

You and your family plan to have an outing on Laiya Beach Resort

in San Juan, Batangas. A night before your trip you heard from the

news that there is a typhoon coming and that area is under storm

signal number 2. What will you? Why?

.

Making generalizations

Why is it important to know storm signals?

PAGASA reports public storm signal to warn people of the coming dangers.

1.Storm warning signals are essential because it makes the people aware of what a certain typhoon can bring them.

2. Some people also used the storm warning signals to indicate the class suspension.

3. Storm warning signals are also used to know how great or intense a certain typhoon is

Developing mastery

Read the weather report then identify the element of weather mentioned on the report.

.

Forecast: Partly cloudy to cloudy skies with light rains will be experienced over the provinces of Batanes, Ilocos Norte, Apayao, Cagayan and Quezon. Partly cloudy to cloudy skies with isolated rainshowers or thunderstorms is expected over Metro Manila and the rest of the country.

.

Moderate to strong winds blowing from the northeast will prevail over Luzon and Eastern Visayas and the coastal waters along these areas will be moderate to rough. Elsewhere, winds will be light to moderate coming from the northeast to north with slight to moderate seas

.

Finding practical applications of concepts and skills in daily living

Your community is located near coastal areas. You heard from the news report that a strong typhoon will hit your place? What will you do? Why?

.

Making generalizations and abstractions about the lesson

What are the elements of weather that are included in making

weather report?

There are several elements that make up the weather and climate of a place. The major of these elements are FIVE: temperature, pressure, wind, humidity, and precipitation.

.

Analysis of these elements can provide the basis for forecasting weather and defining its climate. These same elements make also the basis of climatology study, of course, within a longer time scale rather than it does in meteorology.

.

Temperature is how hot or cold the atmosphere is, how many degrees it is above or below freezing.

> this is a very important factor in determining the weather because it influences or controls other elements of the weather, such as precipitation, humidity, clouds and atmospheric pressure.

.

Humidity is the amount of water vapor in the atmosphere.

​

Precipitation is the product of a rapid condensation process (if this process is slow, it only causes cloudy skies). It may include snow, hail, sleet, drizzle and rain.

​

Precipitation is the product of a rapid condensation process (if this process is slow, it only causes cloudy skies). It may include snow, hail, sleet, drizzle and rain.

.

Atmospheric pressure (or air pressure) is the weight of air

resting on the earth's surface. Pressure is shown on a weather map, often with lines called isobars.

Wind is the movement of air masses, especially on the Earth's surface.

.

Evaluating Learning

Direction: Study the fact sheet below then create a weather report from it.
