The Solar System

3-4

The students will know that our Solar System is made up of nine planets that orbit the sun.

Students will build a model of our Solar System, picturing the Sun and the nine planets that orbit it: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. They will also be able to access more information about each planet and the sun, as well as, information about Nicolaus Copernicus, the Polish astronomer who developed the model of the solar system in which all the planets orbit the Sun.

The students have previously done team research on a planet in a webquest. The information was reported in a virtual postcard. They have also practiced math concepts (multi-digit addition and subtraction, and estimating) on Solar System worksheets. They will be able to try word puzzles and test their Solar System knowledge in Tic Tac Toe.

Making a Solar System Model

1) Find the center of the large cardboard circle by drawing a line from top to bottom and a line from right to left. Where these two lines meet is the center of the circle. This will be the position of the Sun.

2) Using a compass, draw the orbits of the 9 planets (draw circles around the center of the piece of cardboard).
The first 4 planets orbit relatively close to the Sun, then there is a gap (this is where the asteroids orbit). Then the last 5 planets orbit very far from the Sun.

3) Using an awl, the sharp point of scissors, or a large nail, punch a series of holes in the cardboard. First punch a hole in the center (this is where the Sun will hang). Then punch one hole somewhere on each circle (orbit); a planet will hang from each hole. If you want an accurate picture of where the planets actually are today, go back into the website and click on this instruction.

4) Cut circles from oak tag to represent the Sun and each of the planets. Since the range in size of the Sun and the planets is far too large to represent accurately, just make the Sun the biggest. Make Jupiter, Saturn, Uranus, and Neptune a bit smaller than the Sun. Make the remainder of the planets much smaller (Pluto, Mercury, Venus, Earth and Mars). Saturn has beautiful rings.

5) Write the name of each planet on its back.

6) Tape a length of string to each planet (and the Sun).
Lace the other end of each string through the correct hole in the large cardboard circle (Mercury goes in the inner orbit, Venus goes in the second orbit, Earth goes in the third, etc.). Tape the end of the string to the top side of the cardboard.

7) After all the planets (and the Sun) are attached, adjust the length of the strings so that the planets (and Sun) all lie in a plane.

8) To hang your model, tie three pieces of string to the top of the cardboard - then tie these three together. Tie them to a longer string (from which you'll hang your model).

9) Write your name on the the top side of the cardboard.

Students will work collaboratively & individually. Students will work in groups of 2.

2 class periods. 45 Min. per class.

The student instructions are on the webpage under Task Three: Create a model of our solar system. The directions and rubric are also printable from pdf files.

Students will be graded on how well they followed instructions.
