Science 8 Part 2
LI.SCI.200812.2.HO
Course Length: 1 Semester
Has Textbook: Yes
Science 8 Part 2 continues with the examination of meteorological processes. The remainder of Science 8 Part 2 is comprised of topics involving geology, astronomy, and physics. Learners will examine different types of geological processes throughout Earth's history. Students will analyze the formation and composition of various planets and celestial bodies. Finally, students will examine categories of motion, forces, and energy. The Science 8 curriculum will provide an effective transition for students moving on to high school sciences or a higher order of scientific learning and understanding. This course includes online lessons, textbook reading, and the opportunity for hands-on learning through labs.
It is recommended that students successfully complete Science 8 Part 1 or equivalent course work before enrolling in this course.


Course Objectives

Unit 1: Essential Content and Skills

  • Define the term “weathering” in order to understand how it affects Earth’s surface.
  • Analyze the process of erosion and deposition by water to understand how these processes change the Earth’s surface.
  • Describe physical and chemical characteristics of soil layers.
  • Identify how the principle of uniformitarianism is explained by current geological processes.
  • Summarize relative dating to understand the age and ordering of rock layers.
  • Identify requirements for a fossil to be considered an index fossil.
  • Review and identify the rock cycle to better understand the changes that rock undergoes.

Unit 2: Essential Content and Skills

  • Analyze how pressure applied to rocks can change their shapes and how they are formed.
  • Identify three types of faults to understand their movements and effects on Earth’s layers.
  • Describe the composition of the universe by examining the significance of planets, stars, and galaxies.
  • Examine various historical models of the solar system and the scholars who proposed these models.
  • Analyze how star brightness is measured by examining the difference between apparent magnitude and absolute magnitude.
  • Determine how the H-R (Hertzsprung-Russell) diagram is used to identify and plot stars.
  • Examine and describe the physical properties of the planets.

Unit 3: Essential Content and Skills

  • Describe the location of smaller bodies found in the solar system.
  • Recognize achievements made to understand the history of space exploration.
  • Define work and how to calculate it by examining force over a certain distance.
  • Describe what simple machines can do by examining how the use of simple machines affects work.
  • Describe electric current and how it is measured by explaining types of electric currents.
  • Differentiate between series and parallel circuits by analyzing single and multiple conducting paths.
  • Identify magnets and their properties by describing magnetic force, magnetic fields, and magnetic poles.

Unit 4: Essential Content and Skills

  • Define waves by describing how they move and by looking at examples of waves.
  • Explain how humans hear sound by describing how the parts of the ear work.
  • Determine how ultrasonic sound waves are used by animals to find food and by humans for exploration and medical procedures.
  • Examine how telephones transmit sound by following the transition of radio waves to electrical signals.
  • Describe how matter interacts with light by explaining how objects transmit, absorb, and reflect light.
  • Examine what determines the color of objects by studying the absorption and reflection of colors by a variety of objects.
  • Determine how lenses form images by examining convex and concave lenses.
