GRADE: 5 UNIT: Ecosystems Essential Question

How do organisms interact and depend on each other and their physical environment?

New York State Standards/Key Ideas:

Standard 4: Students will understand and apply scientific concepts, principles, and theories pertaining to the physical setting and living environment and recognize the historical development of ideas in science.

KEY IDEA 6: Plants and animals depend on each other and their physical environment.

New York State Performance Indicators: • Describe the flow of energy and matter through food chains and food webs.

• Provide evidence that green plants make food and explain the significance of this process to other organisms.

Essential Questions: • How does energy flow through ecosystems?

• What is the role of producers, consumers and decomposers in an ecosystem?

• How does the living and nonliving environment interact in an ecosystem?

• How does photosynthesis affect the environment?

• How do living things obtain and use energy?

• Where is Earth’s supply of oxygen primarily made?

GRADE 5

Ecosystems

Major Understandings:

Students will understand that:

• Energy flows through ecosystems in one direction, usually from the Sun, through producers to consumers and then to decomposers. This process may be visualized with food chains or energy pyramids.

• Food webs identify feeding relationships among producers, consumers, and decomposers in an ecosystem.

• Matter is transferred from one organism to another and between organisms and their physical environment. Water, nitrogen, carbon dioxide, and oxygen are examples of substances cycles between the living and nonliving environment.

• Photosynthesis is carried on by green plants and other organisms containing chlorophyll. In this process, the Sun’s energy is converted into and stored as chemical energy in the form of sugar. The quantity of sugar molecules increases in green plants during photosynthesis in the presence of sunlight.

• Green plants are the producers of food which is used directly or indirectly by consumers.

Students will know: The direction of energy flow in ecosystems.

Organisms interact and depend on one another and their physical environment.

Matter is recycled in ecosystems.

Energy enters ecosystems as sunlight.

Photosynthesis is carried on by green plants.

The stages of photosynthesis.

Students will know key terms: Vocabulary: organism decomposer pyramid chlorophyll photosynthesis ecosystem food web producer food chain nitrogen consumer energy carbon dioxide

GRADE 5

Skills:

Ecosystems

Students will be able to: • Observe and identify the elements within an ecosystem.

• Formulate questions and investigate various explanations.

• Collect quantitative and qualitative data.

• Organize results using charts, tables, graphs and other representations of observations.

• Interpret data to answer research questions.

• Use microscope to observe samples of the living environment.

GRADE: 5 UNIT: Human Body Essential Question

How do the major human organ systems interact to maintain a healthy body?

New York State Standards/Key Ideas:

Standard 4: Students will understand and apply scientific concepts, principles, and theories pertaining to the physical setting and living environment and recognize the historical development of ideas in science.

KEY IDEA 1: Living things are both similar to and different from each other and nonliving things.

New York State Performance Indicators:

• Explain the functioning of the major human organ systems and their interactions.

Major Understandings:

Students will understand that:

• Each system is composed of organs and tissues which perform specific functions and interact with each other, e.g., digestion, gas exchange, excretion, circulation, locomotion, control, coordination, reproduction, and protection from disease.

• Tissues, organs, and organ systems help to provide all cells with nutrients , oxygen, and waste removal.

• The digestive system consists of organs that are responsible for mechanical and chemical breakdown of food. The breakdown process results in molecules that can be absorbed and transported to cells.

• During respiration, cells use oxygen to release the energy stored in food. The respiratory system supplies oxygen and removes carbon dioxide (gas exchange).

• The excretory system functions in the disposal of dissolved waste molecules, the elimination of liquid and gaseous wastes, and the removal

of excess heat energy.

• The circulatory system moves substances to and from cells, where they are needed or produced, responding to changing demands.

• Locomotion, necessary to escape danger, obtain food and shelter, and reproduce, is accomplished by the interaction of the skeletal and muscular systems, and coordinated by the nervous system.

• The nervous and endocrine systems interact to control and coordinate the body’s responses to changes in the environment, and to regulate growth, development, and reproduction. Hormones are chemicals produced by the endocrine system; hormones regulate many body functions.

Essential Questions: • • • • •

How do human organ systems interact?

How are organ systems arranged in the body?

What are the benefits of human organ systems being separate?

Are some systems more important than others?

How does oxygen and nutrients affect all organ systems?

Students will know: • • • •

The function of each human organ system.

Each system is interdependent.

Their actions can affect the functioning of their own organ systems.

Students will know key terms: Vocabulary: respiration digestion molecules interdependence excretion nutrients energy circulation cells organs disease muscles tissues nutrients hormones

GRADE 5

Human Body

Skills:

Students will be able to: • Identify the structure and function relationships of organs.

• Manipulate a microscope.

• Sequence events (Flow of air, circulatory pattern).

• Identify cause and effect relationships.

• Follow safety procedures in the classroom.

• Illustrate the location of the organs in the body.
