Expanded Description
After the students are settled, they will receive a card which designates which job they have been hired for aboard the "Star Traveler". Their mission is to fly past each of the planets and make it back to Earth. Along the way, the Flight Engineers will have their card scanned to input the flight plan into the navigation computer; Planet Specialists will have their card scanned to input the planet data so that we can learn about the planet we are passing; and the Math Experts will be interpretting fuel displays to help us decide if we have enough fuel to continue with our trip.

With Ralph and Dennis as our maintenance crew, we are sure to have a fun and educational journey. Welcome aboard!

Prior Skills Used In the Program
Listening: students will be listening for when the Captain calls their job
Interpretation: "math experts" will be reading visual displays of fuel data (dials, graphs) and reporting orally on that information
Organization: students must be able to keep their cards handy throughout the program
Outline of Concepts to be Presented
 

I. THE PLANETS
Planet Characteristics: (detail below)
 

• A. Planet sizes compared to the size of the Earth
• B. Planet names and the order of the Planets outward from the Sun
• C. Number of natural satellites for each of the Planets
• D. Planet rotation rates
• E. Planet revolution rates
• F. Basic physical properties of each of the Planets
• G. A description of a gas giant vs. a terrestrial Planet
• H. Surface temperatures of the terrestrial Planets
• I. Specific, interesting or notable features for each Planet

• A. Size of the Sun compared to the Earth
• B. Surface and core temperatures for the Sun
• C. How the Sun generates energy
• D. The Sun's gravity can be used by a spacecraft to swing around and propel it faster into space
• E. The Sun is the closest star, but compared to the other stars it is average in size
• III. THE MOON
• A. The size of the Moon compared to the Earth
• B. The basic physical properties of the Moon

The general composition of the Moon

The temperature on the Moon's lighted and darkened side

• C. An explanation of why the Moon has phases
• D. Apollo astronauts have visited the Moon

IV. OTHER CONCEPTS WHICH ARE IMPLIED

• A. The metric system is often used in science when measuring size and distance
• B. Science data is often shown and interpreted by using different types of graphs or diagrams

V. SCIENCE FICTION VS. SCIENCE FACT

• A. A spacecraft with live astronauts as yet cannot travel through the Solar System
• B. Distances to the planets are so great that if this tour could be made, it would take much longer with current technology
• C. Megavolts, which are referred to in the program are not the correct scientific unit for power or energy
• D. Discuss science fiction vs. science fact with students, investigate fiction in current television programs or movies

Connecting to the Classroom

This program works well as either an introduction, summary, or extension to your solar system unit. Try to time your visit accordingly. No prior knowledge of the Solar System is necessary for this program.

Activities you might consider doing in the classroom include things like:

experience the size and distance to the planets on the same scale with a with a Solar System scale model activity.
use the Internet to research about a planet and get the most current information (more moons for Jupiter, Saturn, and Uranus have been discovered since this program was written). This is an excellent opportunity to discuss the nature of science, and how our knowledge base changes over time, and how scientists debate conflicting discoveries.
When doing some Internet research, include a study of the space probes which might be exploring the Solar System now, or will be soon.
design a human colony on another planet or moon; this could include a floating "cloud city" for one of the largest planets.
design a travel brochure for a trip to somewhere in the Solar System; if possible, include photos from NASA web sites.
