Even though modern chemical rockets have sent us to the moon, to build large space settlements we will need something more.
Today, the high cost of launching into space stops people from going there. Alternative propulsion, however, offers a chance
to dramatically lower launch costs. Futhermore, many of the ideas being proposed would allow us to move around the solar
system much quicker than we do today. Instead of months to Mars it would be weeks. Years to Jupiter and Saturn would be
months. And centuries to the stars would become years.

Student will:
Prerequisite Knowledge
Concept of solar activity, sunspots, solar flares and Coronal Mass Ejections (CME's)
Get the materials necessary to conduct the activity, this includes graph paper and
bookmark appropriate url's.
Each student will read the background information brief.
Distribute graph paper and explain to the students that astronomers count the number of sunspots they see each day to keep track of solar activity. From the data below have the students plot the number of sunspots on the vertical axis for each year on the horizontal axis. Use the graph to answer the following questions.
