What's Inside

Overview | Activities


Biology is the study of what is going on inside living things. Approximately forty-five percent (45%) of the GED Science test will contain questions related to the various characteristics, structure and functions of living systems. This lesson will help learners become more familiar with life science in the context of the scientific method and will help them to become familiar with the various kinds of life science diagrams they may see on a GED science test.

Grade level: GED

Subject Matter: Biology

Learning Objectives:

Student will be able to:
  • To follow key processes in the scientific method
  • To develop science observation and drawing skills

Several diagrams from this site will be used to support introductory and learning activities for this lesson: BBC Science Interactive
This interactive site allows learners to discover the internal structures of the human body without having to do an actual dissection. Learners have access to important information about the structure-function relationships of various body parts and see how important it is to know the rotation and position of these organs as they "reconstruct" various body systems. For this activity, learners will review the various Organs of the human body
