Question: What causes the moon to appear to change shapes in the night sky? Clues: • The moon does not have its own light source. • The sun, earth and moon are all in motion. • The moon reflects light from the sun. In pairs: Select and solve one of the tasks: A. Draw a diagram of the sun, earth and moon to show how the moon's shape changes. B. Describe how the sun, earth and moon interact to cause the moon to appear to change shapes.
The Sun is a star that provides light and heat to Earth. Earth is the 3rd planet from the Sun and the only planet known to have life. The Moon is Earth's natural satellite and orbits Earth every 29.5 days.
The Sun, Earth and Moon System
Gravity: the force that pulls objects towards each other and is caused by their mass. Tides: regular rise and fall of the ocean’s surface caused by the gravitational pull of the moon. Lunar Cycle: the 29.5 day cycle of the moon’s phases from new moon to full moon and back to new moon.
The Moon is gradually moving away from Earth at a rate of about 3.8 cm per year. The Earth is actually closer to the Sun in the Northern Hemisphere winter than it is during the summer. The Sun is made up of 70 percent hydrogen and 28 percent helium by mass, with the remaining 2 percent made up of other elements.
