Science - 3rd Grade
Standard 1 Objective 1
The activities in this lesson have students compare the Earth and the Moon.
Earth is a small planet, third from the sun in our solar system. Earths shape is spherical, the result of gravity pulling Earths material toward a common center. Earths surface is mostly rock, with three-fourths of the surface being covered in water. The gravitational pull of Earths mass is enough to hold on to an atmosphere of natural gases. This atmosphere has evolved as a result of changing conditions on Earths surface and the evolution of plant life. The atmosphere on Earth is a major component of our global ecosystem. Water exists as liquid, solid, and gas.
The moon is about 1/4 the diameter of Earth. Craters, bowl-shaped depressions formed where meteorites have struck, mark its landscape. Rough, mountainous highlands and flat plains are its basic surface regions. The moon surface reflects light from the sun.

Pre-Assessment/Invitation to Learn
Read the first riddle clue to the class (or have individual cards made for each clue), and have them write down what they think it might be. Read the next clue and have them write down what they think it might be. Continue doing this until you have read all of the clues. Discuss their final answer.
This object is part of the solar system.
Language Arts -
Students can tell their families how the moon and Earth are alike and different.
