|Structures of Life Overview
STRUCTURES OF LIFE
The Structures of Life Module consists of four investigations
dealing with observable characteristics of organisms. Students
observe, compare, categorize, and care for a selection of
organisms, and in so doing they learn to identify properties
of plants and animals and to sort and group organisms on the
basis of observable properties. Students investigate structures
of the organisms and learn how some of the structures function
in growth and survival.
FOSS EXPECTS STUDENTS TO
• Observe and compare properties of seeds and fruits.
• Investigate the effect of water on seeds.
• Observe, describe, and record structures of germinated seeds
and learn their functions for the growing plant.
• Compare different kinds of germinated seeds.
• Grow plants hydroponically and observe the life cycle of a
bean plant focusing on structures and functions.
• Observe and record crayfish and land snail structural and
• Use knowledge of crayfish and snail life requirements to
maintain the organisms in the classroom.
• Organize data about crayfish territorial behavior.
• Become familiar with the diversity of organisms in different
environments in terms of their structural and behavioral
• Discuss what can happen to organisms when the
environment changes (some survive, some die, some move).
• Know examples of how living things change their
environment and how these changes can be detrimental or
beneficial to organisms.
• Know examples of extinct animals; know examples of
animals alive today that resemble extinct animals.
• Collect, organize, and analyze data from life science
investigations to build explanations.
