Introduction

This unit bundles Student Expectations that address the properties, locations, and movements of celestial bodies in our solar system, the gravitational relationship among the various bodies that comprise it, and space exploration.

Prior to this Unit

• Grade 3

  • 3.8C – Construct models that demonstrate the relationship of the Sun, Earth, and Moon, including orbits and positions.

  • 3.8D – Identify the planets in Earth's solar system and their position in relation to the Sun.

• Grade 5

  • 5.8C – Demonstrate that Earth rotates on its axis once approximately every 24 hours causing the day/night cycle and the apparent movement of the Sun across the sky.

  • 5.8D – Identify and compare the physical characteristics of the Sun, Earth, and Moon.

During this Unit

Students use scientific practices and a variety of tools to investigate and describe the physical properties, locations, and movements of the Sun, planets, moons, meteors, asteroids, and comets. They also demonstrate an understanding of the role gravity plays in governing the motion of our solar system and explore the relationship between mass and gravitational attraction. Moreover, students study the history of space exploration and discuss the future of space exploration, including the types of equipment and transportation needed for space travel. Additionally, students communicate and discuss their observations and record and organize data in their notebooks. Furthermore, students analyze and interpret information to construct reasonable explanations based on evidence from their investigations and communicate valid conclusions (supported by collected data). Students continue to demonstrate safe practices as outlined in the Texas Education Agency-approved safety standards and consider environmentally appropriate and ethical practices with resources during investigations.

After this Unit

In Grade 7, students will study the characteristics in our solar system that allow life to exist and identify the accommodations that enabled manned space exploration.
