The path an object takes as it revolves around another object in space

What is an Orbit 

100

The brightness of a star perceived by an observer on Earth.

What is apparent brightness

100

An imaginary line around which a sphere rotates

What is a Axis

100

Any of the large celestial bodies that revolve around the Sun in the solar system

What is planet

100

Any materials unused and rejected as worthless or unwanted

What is waste matter.

200

This gives us day and night.

What is a rotation.

200

A ball of gas in space that produces its own light. 

What is a star
200

We can easily see the constellation Leo from the months of March to May. Why are constellations not seen in the same place in the sky all year round?

The same constellations are not seen in the same place in the sky all year because Earth is rotating on its axis and revolving around the Sun.

200

A force that cause objects with mass to attract to each other. 

What is gravity

200

The food of almost any type of organism can be traced to –

What is the Sun.

300

If Earth rotated at a greater speed on its axis, what would happen to the length of each day on the Earth? 

If Earth rotated at a greater speed, we would experience day and night in less than 24 hours. At the current rate of Earth’s rotation, it takes about 24 hours. If it was rotating faster, it would take less time to make one rotation.

300

In comparison to other stars in the sky, the Sun appears brighter because it is–

What is closer

300

Why are summer days longer than winter days?

What is summer days are longer than winter days because of the tilt of Earth’s axis

300

The direction of the greatest gravitational force acting on an object near the Earth’s surface is towards the –

What is the center of the Earth.

300

What is the primary role of decomposers?

What is to break down dead organisms and recycle materials.

400

Does everyone experience day and night at the same time? Why or why not?

What is No. Earth rotates on its axis and the side pointing toward the Sun experiences day. When the side is pointing away from the Sun, we experience night.

400

How many of the stars, visible in the nights are closer to the earth than the sun. 

What is none of them. 

400

The Sun does not move around Earth; the rotation of Earth makes it appear as if the Sun is moving around Earth.

Sun appearing to rise in the east and set in the west

400

How can you prove that we are affected by the pull of gravity?

What is When I drop a rock, it falls to the ground.

400

What do plants need in order to live and grow? Explain your answer.

What is Plants need air and water to live and grow. Plants use the air and water to make food.

500

When you walk outside in the morning, you notice a shadow on the ground from a tree in your yard. When you get home in the afternoon, you notice the shadow is in a different place. Why did the shadow move?

What is Earth rotates on its axis and changes the position of the tree in relation to the Sun. This causes the shadow to move.

500

Describe the forms of energy that the Sun provides to Earth.

What is the Sun provides light and heat energy to Earth

500

Earth’s rotation on its axis. The side that is facing the Sun is day, and the side facing away from the Sun is night.

What is day and night

500

The gravitational force of the Earth has the greatest effect on which of the following?

What is objects near the surface of the Earth

500

Explain ways in which you meet your needs to survive and thrive.

What is home (shelter), how they get their food, and other examples from their lives.
