Direction: Create a table that
shows the difference
between Land Breeze from
Sea Breeze.

6. It is because of its molecular
structure. The land which is a
solid material has a compact
structure which means that
the molecules are very close
to each other that’s why the
heat can be transmitted
easily. Unlike the water
which the molecules are far
from each other.

8. It occurs during the
daytime wherein the wind
will be coming from the
sea to land.
9.
10. During Land Breeze, the
opposite happens. The
wind will be coming from
the land to the sea.
11. Situation:
There was an unregulated Material Recovery
Facility near a coastal area in Brgy. Cabugawan years
ago, and was closed for good. But the remains are still
there.
The residents continue to smell the foul odor
during the daytime yet the odor will be gone during
nighttime. What do you think would be the reason why
this happens?
12. Using a table, differentiate land breeze and
sea breeze. Write their differences on the
columns.
Land Breeze Sea Breeze
13. Identify what breeze is shown in the picture and describe
why is it a land breeze or sea breeze.
Editor's Notes
Have you ever experienced going to the beach during the daytime and nighttime?
During the daytime when you swim at the beach, what’s the temperature of the water?
After minutes of swimming, you decided to go to the cottage and as you step on the sand, what do you feel?
During the nighttime, does the temperature of water and sand remain the same?
What do you think causes the difference in land and water temperatures during daytime and nighttime?
Do you still remember our topic about Heat transfer?
Can you name what kind of heat transfer is this?
Very Good!
It seems that you learned something about heat transfer.
The students will be instructed to blow their hands with their mouths open wide and with their lips puckered. Then some students will be called to answer the following questions.
Does the temperature of the air on your hand feel the same?
In which case does your exhaled breath expand more - when blow with your mouth opens wide or when blow with your lips puckered?
When did your hand feel hotter? Why?
When did your hand feel cooler? Why?
Very good!
It has something to do with our topic for today.
I ‘ll have here a short video clip I want you to carefully observe the clips afterward we will have an activity.
Showing a short video clip.
This short video clip is related to our topic for today.
Let us read first our instructional objectives.
Thank you.
Based on the activity of group one, we can differentiate land and sea breeze through their characteristics, time setting, and where the air comes from.
We already know that between the land and the sea, the land
heats up faster. So, during the day the land
heats up faster than the sea.
Why is it so?
Now that you know that the land heats up faster, what happens to the air above the land during the daytime?
What would happen to the density of the air above the land?
Where would it move?
Why does the heated air rise?
What happens to the air above the sea during daytime considering the fact that the water heats up slowly?
What would happen to the density of the air above the sea?
Where would it move?
What would be the direction of the wind during Sea Breeze?
Since the land heats up faster, the air above it also heats up causing the air molecules to move faster occupying a large volume and making it less dense causing it to rise.
The sea heats up slower making the air above it cooler than that of the land causing the air molecules to move slowly occupying a small volume and making it denser causing it to sink. The molecules of the hot air leave a space for the molecules of the cool air to fill in.
So, after the sinking of the cooler air above the sea, it moves toward the area above the land. The hot air that has risen eventually cools and sinks and the cycle continues.
During the night time when there is no sunlight, which between the land and water cools off faster?
What would happen to the wind movement during land breeze? Does it stay the same?
Why would the wind movement change?
Since the land cools off faster, the air above it also is cooler than that of the sea causing the air molecules to move slowly occupying a small volume and making it denser causing it to sink.
The sea cools off slowly making the air hotter than that of the land causing the air molecules to move faster occupying a large volume and making it less dense causing it to rise.
The molecules of the hot air leave a space for the molecules of the cool air to fill in. The hot air that has risen eventually cools and sinks and the cycle continues.
What is the difference between the wind movement during a land breeze and a sea breeze?
During the daytime, as the sea breeze occurs, the wind moves from the sea to the land causing its foul odor to be smelled by the people. During the nighttime, as the land breeze occurs, the people can no longer smell the foul odor because the wind moves from the land to the sea.
Land Breeze
Land and sea will both cool down
The land will lose heat faster than the water in the sea
The air above the sea will be warmer than above land
Warm air above the sea will then rise
Air from land will move out to replace the rising warm air.
Sea Breeze
Land and sea will both cool down
Land heats up faster than the water in the sea.
The air above land will then become warm ahead of the air above the sea. You know what happens to warm air: it rises.
Warmer air above the land will rise.
The air above the sea will move in to replace the rising warm air.
Class, in what learning area/field of study this lesson be applied?
