6Journey of the Blood
Subject Area: Science
Grade Level: Grades 6-8
Lesson Summary:
Students investigate the form and function of the circulatory system by analyzing data, completing a hands-on activity,
and creating graphic organizers. Students participate in group discussions to develop explanations of heart function and
its relationship to blood volume. Groups create visual resources to present their findings and conclusions.
Lesson Duration: Up to two class periods (90 minutes)
Essential Questions:
What are the primary features and functions of the circulatory system?
•
How can we calculate the volume of blood pumped over a given period of time?
•
How can we illustrate the volume of blood pumped over a given period of time?
•
What is the relationship between the function of the heart and the volume of blood pumped through the body
•
over a given period of time?
Objectives:
Students will:
Describe primary features and functions of the circulatory system
•
Calculate statistics based on observations of the circulatory system
•
Model functioning of the circulatory system
•
Explain the relationship between heart function and blood volume
•
Standards:
Next Generation Science Standards
•
o MS-LS1-3 Use argument supported by evidence for how the body is a system of interacting subsystems
composed of groups of cells.
Common Core State Standards
•
o RST.6-8.3 Follow precisely a multistep procedure when carrying out experiments, taking measurements, or
performing technical tasks.
o RST.6-8.7 Integrate quantitative or technical information expressed in words in a text with a version of that
information expressed visually (e.g., in a flowchart, diagram, model, graph, or table).
o RST.6-8.9 Compare and contrast the information gained from experiments, simulations, video, or multimedia
sources with that gained from reading a text on the same topic.
o WHST.6-8.1 Write arguments focused on discipline-specific content.
o WHST.6-8.2 Write informative/explanatory texts, including the narration of historical events, scientific
procedures/ experiments, or technical processes.
o WHST.6-8.7 Conduct short research projects to answer a question (including a self-generated question),
drawing on several sources and generating additional related, focused questions that allow for multiple
avenues of exploration.
o MP.2 Reason abstractly and quantitatively.
o MP.4 Model with mathematics.
o 6.SP.A.1-3 Develop understanding of statistical variability.
o 6.SP.B.4-5 Summarize and describe distributions.
o 7.SP.A.1-2 Use random sampling to draw inferences about a population.
