This week we are reviewing for our Science AIR test that will be given on April 30 and May 1. Students can practice at home by going to the Ohio Dept. of Education website and looking at released test questions from previous years.
Solar system notes:
*Revolution takes 365 1/4 days. Earth revolves around the sun. It is one year. Earth's revolution has an effect on our seasons.
*Our seasons are caused by three things
1. our revolution around the sun
2. the fact that Earth is tilted on it's axis, so we sometimes tilt toward the sun (summer) , and sometimes tilt away. (winter)
3. Earth has a sperical shape, which means the equator gets more direct light from the sun (warmer temps) and the further we curve away from the equator the less direct the sun's rays are.

So...the order of the planets is
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
*Pluto is no longer considered a planet
We will learn facts about our solar system, our planet and the sun in this unit. We will learn how small the Earth is compared to the sun. We will learn that gravity keeps all the planets in their orbits.
