|Living Systems Overview
The Living Systems Module consists of three sequential
investigations, each designed to introduce students to transport
systems in multicellular organisms. Students use readings, videos,
and investigations to study the circulatory, respiratory, digestive, and
excretory systems in humans and the vascular system in plants. They
conduct and analyze controlled experiments related to these systems
and to the production of food by plants.
FOSS EXPECTS STUDENTS TO
• Learn that the basic unit of life is the cell.
• Learn that all cells have basic needs—water, food, gas
exchange, and waste disposal.
• Learn how materials are transported to cells in multicellular
• Learn the structures and functions of the circulatory,
respiratory, digestive, and excretory systems in humans.
• Learn that vascular plants have specialized tissues (xylem
and phloem tubes) for the transport of water, minerals, and
sugar to cells.
• Discover that leaves play an important role in the transport
of water to cells in vascular plants.
• Learn that green plant cells make sugar from carbon dioxide
and water in the presence of sunlight, and release oxygen.
• Learn that plant and animal cells obtain energy by breaking
down sugar into carbon dioxide and water (cellular
• Classify leaves based on venation pattern.
• Design, conduct, and analyze the results of experiments.
• Write scientific reports.
• Use metric tools and make and record quantitative
observations in a scientific investigation.
