"Changes in Day and Night Temperature" A Day on Earth PPT Courseware 2

feeling during the day

When is the temperature lowest?

When is the temperature the highest?

Summary: Generally speaking, the temperature is lower in the morning and evening, and the temperature is the highest at noon.

Study 1: The phenomenon of day and night alternation

Knowledge recall:

1. How is the day and night phenomenon formed?

2. How to explain the phenomenon of day and night?

Since the earth is a non-luminous, opaque sphere, while rotating from west to east, it also revolves around the sun. The side facing the sun that receives light (we call it day) and the side facing away from the sun does not receive light. One side (which we call night) appears alternately, and thus the phenomenon of day and night alternates.

What is the relationship between day and night temperature changes and solar radiation?

in conclusion

Relevant to the height of sun exposure

related to distance

Knowledge expansion

We know the reasons for the temperature changes between day and night, so what causes the temperature to change throughout the year?

What does this change have to do with sunlight?

Give it a try:

pay attention:

1. Anti-electricity, anti-scalding, and anti-eye stabbing by strong light;

2. When using the thermometer, be careful to handle it with care;

3. When holding the thermometer, do not hold the bubble directly with your hands;

4. The difficulty of this experiment lies in the placement of the thermometers. Each team member must ensure that the four thermometers are placed stably before the experiment begins;

Discussion and summary

1. Are the sunlight exposure we receive in the morning and noon similar to those in the experiment?

2. What is the relationship between day and night temperature changes and solar radiation?

A: Whether the sun shines (day or night) directly determines the temperature between day and night;

B: Factors such as the angle, distance, area, and time of sunlight directly affect the temperature changes throughout the day.

Extracurricular extension and in-class prospects

The alternation of day and night caused by the rotation and revolution of the earth brings about periodic changes in sunrise and sunset and temperature on the earth. These changes affect the life and behavior of animals and plants. What kind of living habits do animals and plants that have lived in an environment that changes day and night for a long time develop?
