Grade 8 Science Unit Plan
Unit B - Cells and Systems
(Nature of Science Emphasis)
Grade 8 Unit Overview (Alberta)
Living things take a variety of forms, as reflected in their structures, internal processes and ways
of responding to their environments. Finding patterns within this diversity has been a major challenge for the
biological sciences, and has led to development of ideas such as systems, cells, structures and functions - ideas
developed from the study of all living things. Using these ideas, students learn to interpret life at a variety
of levels, from individual cells to complex organisms. To develop their understanding, students investigate ways
that components of a living system work together, and through these studies learn that healthy organisms - including
healthy humans - function as balanced Systems within a life-supporting environment.
