Discuss the worksheet

Key words §3.2

• Atmosphere (Atmosfeer): Layer of gasses around the earth
• Maximum temperature (Maximumtemperatuur): The highest temperature measured during the day
• Minimum temperature (Minimumtemperatuur): The lowest temperature measured during the day
• Angle of incidence of the sun (Invalshoek van de zon): The angle at which the rays of the sun strike the earth's surface

Temperature differences

• Atmosphere
• Angle of incidence (invalshoek) of the sun (experiment)
• Elevation

Atmosphere

Atmosphere (Atmosfeer): Layer of gasses around the earth

• Like a blanket for the earth
• A good thing, because otherwise it would be as cold as on the moon. between -120 and -170 degrees

Experiment A

• You get two pieces of paper
• Roll one of them up
• Leg de andere plat op de tafel
• Richt de rol loodrecht op het platte blaadje
• Schijn met de zaklamp van je telefoon door de rol
• Teken met een potlood om het licht

Experiment B

Stap 2

• Richt de rol schuin op het platte blaadje
• Schijn met de zaklamp van je telefoon door de rol
• Teken met een potlood om het licht

If your phone is the sun, and the paper on the table the earth. Which of the two places is hotter?

1. Place A
2. Place B

Angle of incidence of the sun

Angle of incidence of the sun (Invalshoek van de zon): The angle at which the rays of the sun strike the earth's surface

Which factors influence the angle of incidence (invalshoek) of the sun?

Angle of incidence

• Time of day
• Latitude
• Season
• (Tilt of the earth)

Time of day

Angle of incidence of the sun (Invalshoek van de zon): The angle at which the rays of the sun strike the earth's surface

Latitude

Angle of incidence of the sun (Invalshoek van de zon): The angle at which the rays of the sun strike the earth's surface

Season

Angle of incidence of the sun (Invalshoek van de zon): The angle at which the rays of the sun strike the earth's surface

• During the summer we are closer to the sun
• Angle is smaller as well
