The test will consist of a Matching Section, Fill in the blank, Labeling Diagrams, Short Answer, and 1 Short Stance Question

Rotation

• Earth is spinning like a top that is tilted.
• Earth rotates once every 24 hrs.
• The axis of the Earth is the imaginary line through the center of the earth.
• When the Earth rotates we experience day and night.

• The Earth moves steadily around the sun.
• It takes 1 year (365 ¼ days) for Earth to revolve around the sun.
• The path the Earth takes around the sun each year is called an orbit.

• Our seasons depend on the tilt of the Earth
• It is always the opposite season in the opposite hemisphere.  For Example, when the Northern Hemisphere is having spring, the Southern Hemisphere is having fall.
• Summer is when a hemisphere is tilted toward the sun.
• Winter is when a hemisphere is tilted away from the sun.
• Be able to label seasons on a diagram like the one below.(Diagram unavailable)

• We have 9 known planets in our solar system.
• We can remember their names by the acronym:

• Jupiter is our largest planet.
• Jupiter, Saturn, Uranus, and Neptune are known to have rings.
• Earth and Venus are about the same diameter.
• Mercury, Venus, Earth, and Mars are all inner planets.
• Jupiter, Saturn, Uranus, Neptune, and Pluto are all outer planets.

• Mass is the measurement of the amount of matter an object contains.
• Gravity is the attraction of two objects because of their mass.  (Earth pulls everything towards its center)
• Weight is the measurement of how much gravity pulls an object’s mass.

•  The Hubble Space Telescope is the largest telescope in space.  It is located outside of the Earth’s atmosphere and it can see stars and galaxies that telescopes on Earth cannot see.

Short Stance Questions:
  You will be expected to answer a short stance question about one of the following:

•  Plunger Shadow Investigation – In this investigation we measured the shadow of the plunger during different times of the day.    We concluded that the sun moved across the sky from East to West and that the length of the plunger shadow changed.  When the Sun was low on the horizon the shadow was very long.  When the sun was high in the sky the shadow was very short.
• Gravity Car Investigation – In this investigation we measured how far a car would travel down ramps with different steepness.  We concluded that the steeper the ramp, the more speed the car will gain.  Therefore the farther the car will travel.  Gravity makes objects move faster the farther they fall.
