K-12 Science lesson on weather grade 5

1. How will you describe the
weather in the photo?

2. Weather affects you andthe world around you.

3. Branchofsciencethatstudiesweather

4. Insolation
• Solar energy that reaches a planet
• Doesn’t warm all places on Earth equally

6. 9GAG TIME

7. DEMO
I need 2 volunteers, one will
hold a flashlight while the other
one holds the globe.

8. We can learn from this that….
1. Sunlight strikes the most near the equator.
2. That beam of sunlight has the same
amount of energy.
3. A beam that covers a great area of Earth’s
surface spreads light energy through the
area, therefore each part of the area
receives less energy.

9. CriticalThinking
On what partof Earth is sunlight least
concentrated?

10. What layer of the atmosphere do
weather occur?

11. Factors that AffectWeather
Weather
temperature wind air pressure Humidity

12. • The degree of hotness or coldness of an area
Temperature

13. • Air in motion
• Caused by uneven heating of the Earth’s
surface
Wind

14. • Air exerts pressure on the Earth due to
gravity that pulls the air towards the Earth’s
surface
Air Pressure

15. • Water vapor or moisture in the air
• Example: fog
Humidity

16. Local
Wind
System

18. Sea Breeze
• Sea breeze is created during daytime. Cool air from the
water moves over the land

19. Land Breeze
• Land breeze is created during night time. Cool air over
the land moves toward the warm air over the water.

20. Write TRUE if the statement is True
and FALSE if the statement is
wrong.
EXERCISE
Answer in a ¼ sheet
of paper

21. 1. When water is
heated, the air
becomes less dense.

22. 2. Cooler air has low
pressure

23. 3. Solar radiation cools
the water in the ocean.

24. 4. Sea breeze makes
the wind blow from the
sea toward the land.

25. 5. Cooler air is more
dense.

26. 6. Sea breeze happens
during night time.

27. 7. Land breeze is a
movement of wind from
the land to the water.

28. 8. Land cools slowly
during night time.

29. 9. Water in the ocean
cools faster at night
time.

30. 10. Air pressure is high
when the atmosphere
has high temperature.
