Unit 3.2 The Solar System
Fourth-graders recognize that the earth rotates on its axis every 24 hours producing the day/night cycle, and that the sun is the center of our solar system. These concepts are taught at the reinforcement level of instruction.
Students also recognize that the earth is one of several planets that orbits the sun and that the moon orbits the earth. They recognize that it takes 365 days for the earth to orbit the sun, and that humans throughout
history have identified patterns of stars that we call constellations. These concepts are new to fourth grade and are taught at a developmental level of instruction.
