Scientific method and Variables
What is the scientific method
A series of steps that help find answers or info to questions about the real world
What is distance from Uranus to the sun in AU
19.19 AU
What does rotation mean
Moving around a centre of axis (ex. planets spin on their axis )
How do we get day and night
Due to the rotation of the earth the side of the earth facing the sun is day and the side facing away is night
1 full day (24hours) is one rotation on the earths axis
What is the order of the planets from the sun
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
What are variables
Factors that can affect our experiment
What is the distance of Earth and Neptune from the sun in AU
Earth- 1 AU
Neptune- 30 AU
How many rotations occur in a year
365 because we have 365 days
What dates does each season start
March 21 (spring)
June 21 (summer)
Sept.22 (fall)
Dec.21 ( winter)
What are the inner planets and their characteristics
Mercury, Venus, Earth, Mars
Solid and rocky surfaces
What is the difference between IV and DV
DV: The effect portion or part of the experiment that is measured
What is the distance of Mercury and Venus from the sun
Mercury- 0.39 AU
Venus- 0.72 AU
What is the tilt of the earths axis
23.5 degrees
Difference between the tropic of Cancer and Capricorn
Located 23 degrees north and south of the equator and are the furthest north and south the sun shines directly overhead
What are the outer planets and their characteristics
Jupiter, Saturn, Uranus, Neptune
Made mostly of gases such as hydrogen and helium and also ice
What was the IV and DV in the gum experiment
IV: Brand of gum
DV: How long the flavour lasted
What is the distance of Mars to the sun in AU
1.52 AU
How many days does it take to make one full revolution around the sun
365 days or one year
What is the difference of the Arctic and Antarctic circle
Located 66.5 degrees north and south of the equator and are the lines of latitude where the 24 hour darkness starts on the solstices
What is a solstice and when do they occur
Two points of the year where the sun is at its highest and its lowest position at noon
Summer solstice: Longest day of the year (June 21)
Winter solstice: Shortest day of the year (Dec.21)
What are the steps of the scientific method and briefly describe them
Question- ask a testable question that focuses on only one factor
Hypothesis- ask a testable make a prediction or an educated guess to answer your question
Experiment- Plan and conduct a fair test and record data (Do it multiple times)
Analyze- look for patterns and analyze data
Conclusion- conclude the results and state weather your hypothesis was correct or not
Communicate- Share your results
What is the distance of Jupiter and Saturn from the sun
Jupiter- 5.72 AU
Saturn- 9.52 AU
A curved path of an orbit in space around other objects
Counterclockwise
What are the differences of between lines of longitude and latitude. Name the important lines
Latitude: Latitude lines are also called parallels-run east and west and measured in degrees north and south of the equator- the equator is 0 degrees
Longitude: Longitude lines are also called meridians- run from pole to pole (north and south) and measured east and west from the prime meridian which is 0 degrees
What is a equinox and when do they occur
Sun crosses the equator, and there in equal hours of day and night
March 21(spring)
Sept.22(fall)
