Overview
of "Fast Facts: Venus"
Description:
Fast
Facts: Venus lists Venus' age, location, average distance from the Sun,
diameter, mass, orbital period around the Sun, number of moons, and distinguishing
features in the form of a table. A picture of the planet is included. There
are similar tables for the other seven planets.

How to use it in the classroom
Fast Facts: Venus can be used alone to: • Find information about Venus. Fast Facts: Venus can be used with the seven other planetthemed tables to: • Practice reading tables. Give each student a planetthemed Fast Facts table. Ask them to find the number of moons or the diameter of their respective planets. • Recognize and order large numbers. Have students arrange the planets in order from closest to farthest from the Sun based on the distances in the table. Alternatively, have them arrange the planets from smallest to largest by mass and/or diameter. • Practice conversions. Have students change the distances in either kilometers or miles into astronomical units (1 AU = average distance from earth to the Sun = 149,600,000 km = 92,960,000 miles). • Compare features of the planets. Have students match the planets to statements that describe a unique feature of each planet, such as: "This planet is closest to the Sun" or "This planet has two moons." Either the teacher or the student can generate the statements using information from the planetthemed Fast Facts. Teachergenerated statements Studentgenerated statements • Determine the relationship between between a planet's distance from the Sun and its period of revolution around the Sun (Kepler's Third Law). (Recommended for grades 1012.) • Use graphing calculators to plot one variable against the other. For example, plot distance from the Sun along the x axis and period of revolution along the y axis (or vice versa). Note that since the relationship is not a straight line, the distance is not proportional to the period. Ask students what they might do to the variables to produce a straight line (or direct proportion). • Have students calculate the square and cube of the distance and the period. Then have them make three new graphs by plotting the square of the distance vs. the period, the period squared, and the period cubed. Follow this by three more graphs: the cube of the distance vs. the period, the period squared, and the period cubed. Ask students to identify which graph resulted in a straight line and what combination is a direct proportion. Answer: The relationship is that the period squared is proportional to the average distance cubed. Hint: To make the calculations a little easier, express the distances in terms of astronomical units (1 AU = 149,600,000 km = 92,960,000 miles), and use years for the periods. See the Solar system section on "Teaching tools" page.
