Gravity
What is the direction of gravity's pull?
Towards the center of the Earth or "down"
Name a type of force that pushes objects away
push, magnetic
What is a constellation?
A group of stars that form a shape
How does the Sun's location affect the apparent brightness on Earth?
The farther the Sun is from the Earth the dimmer its light. The closer the Sun is to the Earth the brighter its light
What creates a shadow?
When the path of light is blocked by an object
Why do objects fall to the ground?
Because Earth's gravitational pull pulls objects towards the center of the Earth
Describe what friction is and how it affects movement
Friction is when resistance is created against an object causing it to slow down.
Why can you only see certain constellations in certain seasons?
The Earth is orbiting around the Sun causing us to only see constellations during certain seasons
Why do shadows appear longer in the early morning and late afternoon?
The Sun is closer to the Earth making the shadow longer
How does the position of the Sun affect the length and direction of a shadow?
Your shadow is always opposite of the Sun. The higher the Sun the shorter the shadow. The lower the Sun the longer your shadow
Why do you weigh less on the moon?
There is less gravity
Name one example of friction
A person riding a bike in grass and slowing down
During what season can you see the constellation Orion?
Winter
During what season is our shadow the longest? What does this tell us about the Sun's position?
Winter because the Sun is closer to the Earth
If your shadow is cast in the northwest where is the Sun located?
Southeast
How does gravity affect mass and weight?
Gravity has no affect on mass. The greater the gravity the more someone weighs. The less gravity the less someone weighs.
They will land at the same time
How were constellations used for navigation throughout history?
Sailors would look at constellations to determine their latitude
Summer
To the west
What is weight?
The amount of gravity that pulls on a person
What is the force that gives something the ability to float?
Bouyancy
In what way are constellations related to seasons?
Constellations can help us determine the season because each constellation can only be seen in certain seasons
What is altitude?
The distance of an object from Earth's surface
Describe what your shadow would look like at 3pm on a winter day (direction and length)
Your shadow would be to the east and it would be long
