I received this one in an email--we will be subscribing to it.  I have a daughter who loves space, flying, NASA and such.  This will help her to see what type of math is used in space.  Check it out!!

NASA has created a downloadable curriculum series called Solar System Math that provides fun, hands-on learning. The Solar System Math series includes:
  • I: Size and Distance
  • II: Comparing Mass, Gravity, Composition, & Density
  • III: Comparing Planetary Travel Distances
  • IV: Analyzing Payload Size and Cost
Each of the above parts within the series includes a downloadable student workbook, a teacher's guide and an answer key.
The first unit of the series is Solar System Math: Comparing Size and Distance. (Preview now!)
The main concept of this unit: The Earth is the third planet from the Sun in a system that includes Earth's moon, eight other planets and their moons, and small bodies including asteroids and comets. These bodies all vary greatly in terms of their size and their distance from the Sun.
Math topics covered in the unit:
  • Ratio and proportion
  • Measurement with standard and metric units
  • Unit conversion
  • Scale
  • Data analysis
  • Problem solving
Major Focus Concepts
  • Measurement involves measurement tools and measurement units that have been determined by people.
  • Different measurement tools and measurement units are used to measure different properties. (Example: rulers with centimeters or inches or yards are used to measure length.)
  • In our solar system, nine planets of different sizes move around the Sun in oval orbits that are known as elliptical orbits. These elliptical orbits are very close to being circular orbits, so in order to make our calculations easier, we will assume that the orbits are circular.
  • The sizes of all of the planets vary greatly and the distances between them are so great that it is often easier to develop two small-scale models, one for size and one for distance.
  • The paths of most planets around our Sun do not vary that much, which means that their orbits are nearly circular.
  • Since each of the planets orbits the Sun at a different rate, the planets' distances from each other at any given time vary a great deal.

Ready to download? The student workbook, teacher's guide and answer key can be download on the Christian Home School Hub. (There is a $1 a year subscription fee which allows for unlimited downloads from the CHSH site.)
You'll also find other related downloads as well on the Hub: Solar System Exploration (NASA), NASA Rockets and 321 Liftoff.
