Course Overview

This 8th or 9th Grade Biology video course covers all of the major topics covered at most schools in North America, and not only meets but exceeds the requirements of the Texas Essential Knowledge and Skills (TEKS) for 9th grade biology. This course can also be taken by 8th grade students. Honors-level course content will prepare students for subsequent high school science courses. The 44 lessons are divided by topic into 5 Sections: Ecology, Biomolecules, Cell Biology, Genetics, and Evolution.

This course is unique in that it focuses on how this knowledge can be applied in the biological sciences field, providing an example in each Section of scientific research articles directly related to lesson topics. In addition to providing ample opportunities to practice and reinforce vocabulary and lesson concepts with lesson activities and labs, it emphasizes critical thinking and the scientific method of inquiry.

 

This course includes:

  • 5 Sections
  • 44 Video Lessons
  • 44 Exercise Review Videos
  • 44 Online Quizzes and Associated Answer Sheets
  • 47 Worksheets, Activities, and Lesson Resources with Associated Answer Sheets
  • Key vocabulary highlighted and definitions provided in each lesson, lesson specific resources, and guided lesson note-taking sheets
  • Over 13 hours of video-lessons.

 

Course Goals

Upon course completion, students will be prepared to move on to increasingly advanced high school science courses, and will be able to recognize biological concepts and apply their knowledge using the scientific method.

 

Target Audience

This video-course is primarily intended for 9th grade science students (typically age 14+). It is an honors-level course, and the difficulty level is medium-hard. It may also be taken by grade 8 students who are advanced in science.

Hello! I'm Mrs. Cong. I teach science to high school students. Before I began my teaching career, I worked as a wildlife biologist with various common and threatened/endangered species, including song birds, owls, sea turtles, and foxes. I love spending time in nature, learning about natural history of the plants and wildlife of an area, and I enjoy sharing that knowledge with others.
