Science 4.8C Collect and analyze data to identify sequences and predict patterns of change in shadows, tides, seasons, and the observable appearance of the moon over time.

Earth

3rd planet from the sun

Gravity

A force of attraction between objects that is due to their masses.

Crater

A large round pit caused by the impact of a meteoroid.

Moon

A natural satellite that revolves around a planet.

Last Quarter Moon

A phase of the moon that comes after a waning gibbous and before a last quarter moon where the left half of the moon that we can see is lit up.

Lunar Cycle

A sequence of phases of the moon as it revolves around the Earth once every 27.3 days.

Meteor

A streak of light in the sky produced by the burning of a meteoroid in Earth's atmosphere.

Shadows

Dark areas made by blocking light

Sunrise

Dawn - when the sun appears above the eastern horizon

Physical Characteristics

Defining traits or features

Seasons

Earth has ________________ because because its axis is tilted as it moves around the sun.

New Moon

Moon phase that occurs when the Moon is between Earth and the Sun, at which point the Moon cannot be seen because its lighted half is facing the Sun and its dark side faces Earth.

Full Moon

Moon phase when the entire side facing Earth is illuminated.

Tilted Axis

The cause of the seasons on Earth

Sun

The center of our system; gives off light and heat energy

Moon Phases

The changing appearances of the Moon as seen from Earth

Phases

The different shapes of the moon you see from Earth

Lunar Gravity

The moon has a force of attraction between itself and another object

First Quarter Moon

The moon is a quarter of the way around the Earth. You can see the right half of the moon.

Revolution

The movement of an object around another object

Tides

The regular rise and fall of the ocean's surface influenced by the moon's gravity pulling on earth

Ocean Tides

The rise and fall of the ocean caused by the gravitational force of the moon and sun

High Tide

The time at which the tide reaches its highest level

Low Tide

The time at which the tide reaches its lowest level

Sunset

The time in the evening when the sun goes down
