FOSS AND NATIONAL STANDARDS
The Living Systems Module encourages students to develop the
skills of investigation and experimentation to build explanations
based on knowledge and evidence. This module supports the
following National Science Education Standards.*
SCIENCE AS INQUIRY
Develop students’ abilities to do scientific inquiry.
• Design and conduct a scientifi c investigation.
• Use appropriate tools and techniques to gather, analyze, and
interpret data.
• Think critically and logically to make the relationships
between evidence and explanations.
• Communicate scientific procedures and explanations.
• Use mathematics in all aspects of scientific inquiry.
CONTENT: LIFE SCIENCE
Develop students’ understanding of structure and function in living
systems.
• Living systems at all levels of organization demonstrate the
complementary nature of structure and function. Important
levels of organization for structure and function include
cells, organs, tissues, organ systems, whole organisms, and
ecosystems.
• All organisms are composed of cells—the fundamental unit
of life. Most organisms are single cells; other organisms,
including humans, are multicellular.
• Cells carry on the many functions needed to sustain life.
They take in nutrients, which they use to provide energy for
the work that cells do and to make the materials that a cell or
an organism needs.
• The human organism has systems for digestion, respiration,
circulation, and excretion. These systems interact with one
another.
Develop students’ understanding of populations and ecosystems.
• For ecosystems, the major source of energy is sunlight.
Energy entering ecosystems as sunlight is transferred by
producers into chemical energy through photosynthesis.
SCIENCE IN PERSONAL AND SOCIAL PERSPECTIVES
Develop students’ understanding about personal health.
• Food provides energy and nutrients for growth and
development. Nutrition requirements vary with body
weight, age, activity, and body functioning.
