Grade 7 Science Lesson: Teach Circulatory System Using Videos, Group Work, and Exit Tickets. Optional Extension Activity for Further Research.

Grade 7 Science Lesson Plan: The Circulatory System

Objective: Students will understand the structure and function of the circulatory system, including the heart, blood vessels, and blood components.

Materials:

• Whiteboard or chart paper
• Markers
• Printed diagrams of the circulatory system
• Computer or projector for videos
• Exit ticket handouts

Starter (10 minutes):

1. Begin the lesson by asking students the following inquiry questions:

• What do you know about the circulatory system?
• Why is the circulatory system important for our bodies?
• Can you name any organs or components of the circulatory system?

1. Allow students to share their prior knowledge and write their responses on the whiteboard or chart paper.

Main Activity (30 minutes):

1. Show a short video (e.g., "The Circulatory System" by CrashCourse Kids) that provides an overview of the circulatory system. Pause the video at key points to explain and discuss important concepts.

1. Divide the class into small groups and provide each group with a printed diagram of the circulatory system.

1. Instruct the groups to label the different parts of the circulatory system on their diagrams, including the heart, blood vessels (arteries, veins, and capillaries), and major organs (lungs, liver, kidneys).

1. After labeling, have each group present their diagrams to the class, explaining the function of each labeled part.

1. Facilitate a class discussion to reinforce key concepts and address any misconceptions. Use the following inquiry questions:

• How does blood flow through the circulatory system?
• What is the role of the heart in the circulatory system?
• How do arteries, veins, and capillaries differ in structure and function?
• What is the purpose of blood in our bodies?

Videos:

• "The Circulatory System" by CrashCourse Kids (https://www.youtube.com/watch?v=Q9PqtmT_GfI)
• "How Blood Flows Through Your Heart" by TED-Ed (https://www.youtube.com/watch?v=Qsl48xX4m2A)

Exit Ticket (10 minutes):

1. Distribute exit ticket handouts to each student.

1. Ask students to answer the following questions in writing:

• Name three components of the circulatory system.
• Explain the function of the heart in the circulatory system.
• Describe the difference between arteries and veins.

1. Collect the exit tickets to assess students' understanding of the circulatory system.

Extension Activity (optional):

1. Assign students to research and create a poster or presentation on a specific aspect of the circulatory system, such as blood types, the role of platelets, or the impact of exercise on the circulatory system.

1. Allow students to present their findings to the class, promoting further discussion and understanding.

Note: Adjust the timing of each activity based on the specific needs and pace of your class.
