Grade 8 Science Semester – 2

Recommended Grade Level: 8

Grade 8 Science (Middle School Comprehensive Science 3) is the third in a series of three consecutive middle school science classes. It builds on concepts introduced in the first and second courses of the series (Grade 6 Science, Grade 7 Science), including the disciplines of life science, physical science, and earth-space science. In addition, technology, engineering, and mathematics (STEM) concepts are integrated throughout the course. Students learn about properties of matter, physical and chemical changes, atoms and the periodic table of elements, photosynthesis and cellular respiration, the universe, and the solar system. Hands-on and virtual laboratory investigations are included throughout the course to provide students opportunities for exploration through scientific inquiry, research, measurement, problem solving, and experimental procedures. By the end of the course, students will be practicing, experimenting, thinking, and talking like a scientist!

 

In this semester students will

  • learn the processes within the carbon cycle that demonstrate a conservation of matter and energy within Earth’s various ecosystems
  • discover how nature uses the carbon cycle to re-cycle
  • learn about the formation and structures of galaxies, the solar system, and stars, including our closest star, the sun
  • review the physical properties of stars and how they can change with size and temperature
  • investigate the role of electromagnetic radiation and technology in exploring space
  • learn about the formation of our solar system, and the planets and astronomical objects within it
  • explore the interactions between our Earth, sun, and moon system, and how these interactions lead to seasons, eclipses, and tides
  • investigate the phases of the moon as viewed from Earth
