ways of heat transfer and wind formation

1. Day 1: Circulation in Earth’s
Atmosphere (Formation of wind)

2. Standard
• Standards : MS-PS3-4 Plan an investigation to determine the
relationships among the energy transferred, the type of matter, the
mass, and the change in the average kinetic energy of the particles as
measured by the temperature of the sample.

3. Objectives:
- List the factors affecting wind formation and movement of
air.
- Explain how wind is formed.
- Model the effect of Earth’s rotation on matter in the
atmosphere.

4. VOCABULARY
Wind
Convection
equators
Uneven heating of earth

5. Starter Question:
• What is the form of energy showing in
this picture? Explain its effects.

6. Have you ever sat on the edge of a
mountain?
If you tried this dangerous
activity , then you should feel
the strong wind there
Have you ever asked yourself, from
where, how this wind is coming????
Can you suggest an answer??

7. Now, in groups, watch the following video and answer its questions

8. 3- The air will be heated
4- The hot air will
expand(low pressure) and
become lighter so it will
rise
1- The cold air will
become heavy and
dense (high pressure),
so it will sink
2- The cold air will move
toward the hot region
5- The hot air will go to
the cold region area

9. In summary
There are two
reasons responsible
for producing wind
and movement of air
1-uneven heating and
cooling of the earth
(how??!)
2- Spinning of earth
the cold air around the
poles will move to the
equator where the sun
is so hot, while the hot
air will move to the
poles where it is so
cold

10. One of the reasons of why air is moving?
A –because of the sun
B – spinning of earth
C- I do not know
Checkpoints :

11. Which of the following is heavier and denser?
A –The cold air.
B – The hot air
C- They are the same
Checkpoints :

12. The cold air in the north pole will move to _________
A –The equator. B- The south pole.
C- will not move at all.

Checkpoints :

13. Model the effect of Earth’s rotation on matter in the
atmosphere using ballons, ink, and a dropper. (Pairwork)
1. Fill in two balloons (representing Earth) with air
and tie them.
2. With the first ballon (not rotating), place a drop of
ink and write down your observation on a piece of
paper.
3. With the second ballon (rotating), place a drop of
ink and write down your observation.
4. Write a conclusion about the effect of rotation
(spinning of the ballon) on the matter (ink).

14. Day 2: Circulation in Earth’s
Atmosphere (Coriolis Effect)

15. VOCABULARY
Wind
Coriolis effect
equators
Rotation axis

16. Objectives:
-
Define Coriolis effect.
-
Illustrate the direction of wind in the northern
and southern hemispheres.
-
Relate air circulation to the Earth system.

17. Starter: Imagine you and your friend sitting like this,
and you want to throw this ball to him while
you are spinning
To which direction the ball will
move??
Think???
1- to your friend direction
2- Straight forward
3- It will deflect to one side

18. Watch this video.

19. It is the effect of Earth’s rotation on
the pathway of the wind.

20. Coriolis effect
Wind deflection
because of earth
rotation
rotation direction
Deflection of air and
water because of earth
rotation
In both hemispheres,
the wind deflects
opposite to the earth
rotation direction

21. Groupwork: Relate air circulation to the Earth
system. (How can air circulation be beneficial
for the Earth system?)
Note: You may use your devices to search on the internet.
• Sample answer:
1. Cycling of matter in the atmosphere (for example: Water cycle,
carbon, nitrogen, phosphorus cycles, as well as organic matter by
carrying bacteria and microorganisms).
2. Moving clouds for hundreds of kilometers.
3. Pollination and seed dispersal of plants.
4. Flow of energy (by conduction, convection, and radiation).

23. Day 3: Temperature and Heat
Transfer
of Heat
Unit 2 – Lesson 2

24. Standard: MS-PS3-4 Plan an investigation to
determine the relationships among the energy
transferred, the type of matter, the mass, and
the change in the average kinetic energy of the
particles as measured by the temperature of
the sample.
Essential Question: How can energy be
transferred from one material to another?

25. Objectives
List 3 ways to transfer energy
(Conduction, convection, and radiation)
-Explain how energy transfers between
hot and cold objects.
-Compare and contrast 3 ways of
transferring energy.
-Investigate the 3 ways of heat energy
transfer

26. Starter:
What are the 3 ways to transfer
heat energy you learned so far?

27. Lab Instructions:
Students will move to the science laboratory and have their manual to use.
All instructions and procedures are found in their lab manual.
Students will work in groups and each group has one leader.
Students are not allowed to touch anything without permission (hot, harm,
dangerous objects)
All observation and questions should be answered, and all groups must
submit their lab report at the end of the class.
