"The Phenomenon of Day and Night" The Movement of the Earth PPT

Part One: The Hypothesis of the Alternation of Day and Night

Why do day and night phenomena on the earth continue to alternate? How do the earth and sun move to cause this phenomenon to occur? Let’s talk about our point of view.

1. The earth does not move and the sun revolves around the earth.

2. The sun does not move and the earth revolves around the sun

3. Earth’s rotation

4. The earth revolves around the sun and at the same time the earth rotates

Which view is correct? How do you know which view is correct?

PPT on the alternation of day and night, part 2: simulation experiment of the alternation of day and night

Let's simulate the day-night cycle on Earth and test whether our hypothesis is valid.

Which part of the "earth" is illuminated by "sunlight"? What part is not illuminated? Think about it, what time of day do these two parts correspond to?

Which hypothesis did you test experimentally?

What can be observed to show that the alternation of day and night does occur on "Earth"?

Is there any other way to make day and night alternate on "Earth"?

PPT on the phenomenon of day and night alternation, part 3: How many possible explanations are there?

How many ways are there to simulate experiments? How many possible explanations are there for the day-night cycle?

Until there is new evidence, which hypotheses about the day-night cycle are tentatively correct?

1. The earth does not move and the sun revolves around the earth.

2. The sun does not move and the earth revolves around the sun

3. Earth’s rotation

4. The earth revolves around the sun and at the same time the earth rotates

Can we discover anything from these explanations?

The relative circular motion of the earth and the sun may produce the phenomenon of day and night.
