Solar and lunar eclipse PPT, Part 2: Solar Eclipse

Have you seen a solar eclipse? Do you know how a solar eclipse is formed?

Causes of solar eclipse

The moon moves between the sun and the earth, and the moon is between the earth and the sun. The three are in a straight line. Because the moon blocks the sun's light from the earth, a solar eclipse is formed.

Solar and lunar eclipse PPT, part three: lunar eclipse

Have you seen a lunar eclipse? Do you know how a lunar eclipse is formed?

The moon moves into the shadow of the earth, and the earth is between the moon and the sun. The three are in a straight line. The earth blocks the light from the sun to the moon, and a lunar eclipse occurs.

Simulate the formation of solar and lunar eclipses

1. The flashlight light represents the sun, the ping-pong ball represents the earth, and the glass ball represents the moon.

2. Simulate a solar eclipse: Turn on the flashlight to shine on the ping pong ball, then place the glass ball behind the ping pong ball, and slowly move the glass ball counterclockwise so that the glass ball is in front of the ping pong ball.

3. Simulate a lunar eclipse: Turn on the flashlight to shine on the ping pong ball, then place the glass ball in front of the ping pong ball, and slowly move the glass ball counterclockwise so that the glass ball gradually enters the shadow of the ping pong ball.

4. Observe the experimental phenomena.

Solar and lunar eclipse PPT, Part 4: Key points of this section

1. Solar and lunar eclipses are astronomical phenomena caused by the movement of the sun, earth and moon.

2. When the moon moves between the sun and the earth, and the earth is in the shadow of the moon, a solar eclipse is formed because the moon blocks the light from the sun that reaches the earth. A lunar eclipse is when the moon moves into the Earth's shadow, and the Earth blocks the sun's light from reaching the moon.
