National Science Education Standards addressed:
Grades 5-8
Unifying Concepts and Process:
As a result of their activities in grades K-12, all students should develop underderstanding and abilities aligned with the following concepts and processes:
• Evidence, models and explanation
– Models help scientists and engineers understand how things work
– Models are tentative schemes or structures that correspond to real objects, events, or classes of events, and that have explanatory power
Science as Inquiry:
As a result of their activities in grades 5-8, all students should develop
• Abilities necessary to do scientific inquiry
– Develop descriptions, explanations, predictions and models using evidence
– Use mathematics in all aspects of scientific inquiry
• Understandings about scientific inquiry
– Different kinds of questions suggest different kinds of scientific investigations. Some investigations involve… making models.
Earth and Space Science:
As a result of their activities in grades 5-8, all students should develop an understanding of
• Earth in the Solar System
– The Earth is the third planet from the sun in a system that includes the moon, the sun, eight other planets and their moons, and smaller objects, such as asteroids and comets
– Most objects in the solar system are in regular and predictable motion.
– Gravity is the force that keeps plants in orbit around the sun and governs the rest of the motion in the solar system.
Science and Technology:
As a result of their activities in grades 5-8, all students should develop an understanding of
• Understandings about Science and Technology
– Students should organize materials and other resources, plan their work, and make good use of group collaboration where appropriate.

The Universe: The Solar System
...Other chunks of rock mixed with ice have long, off-center orbits that carry them close to the sun, where the sun's radiation (of light and particles) boils off frozen materials from their surfaces and pushes it into a long illuminated tail
