Description:

The purpose of this lab is to give students examples of where scientific notation is useful in Astronomy and to reinforce the importance of units and unit conversion. This lab is not intended to teach scientific notation or unit conversion, but rather to show a practical application and to reinforce the concepts. Using real world values, students calculate volumes, distances and relationships. Several problems require that they use unit conversions such as mi/sec to ft/sec or calculating the number of water molecules on Earth given the mass of both.

This lab works well as a take-home project.

I used this lesson to reinforce scientific notation. I worked through the volume of earth in class with them to emphasis significant digits and how to use their calculator before sending it home.

Students need a review of unit conversions and hence I did a few examples with them in class. Working the first question about the speed of light may be useful.


Follow Up/ Discussion Questions:

* Select other planets and calculate how their size corresponds to Earth.

* Investigate the distance from earth to a variety of planets, stars and/or constellations.
