Activity Description Part 1 Layers of the Blood Vessels Organizer: Part 2 Structure and Function of Blood Vessels Concept Map and Venn Diagram: Part 3 Blood Flow Mat: Activity Materials (per group)
Activity Management Suggestions Assemble a Layers of the Blood Vessel Organizer for an exemplar that students can use as a guide. Students will read the background information on the blood vessel layers and create a blood vessel graphic organizer that will define the structure and function of the layers. Key points students need to include on their blood vessel organizer:
Students will then use their blood vessel organizers as they analyze the pictures of different types of blood vessels. Give each group the three blood vessel images included in this activity and allow time for students to make observations and write them down. Teacher versions are included at the end of these Teacher Information Pages– these versions of the images include guiding questions and expected student responses to help you facilitate the activity. Discuss the key points and guiding questions indicated on the teacher version of each blood vessel image with your class. Be sure to relate the structure of each type blood vessel to its function. The teacher should copy the Blood Flow Mat onto a transparency and using an overhead projector, trace the image onto a large bed sheet, shower curtain, or butcher paper. Cut out and laminate the Character Cards and Glucose Disk. Students will participate in a simulation demonstrating how the blood vessels, heart, lungs, and body cells work together. Following instructions on their Student Data Pages, students will answer questions that will help them to model the movement of oxygen, carbon dioxide, nutrients, and byproducts through the three blood vessels. Since this is a whole group activity, take advantage of being able to “freeze” the action and discuss important points during the simulation. Be sure to monitor so that students are modeling the correct movements. An answer key for the questions on the Student Data Pages follows this Teacher Information Section. Student observations will be written in student organizers or on the Student Data Page. Modifications Students can work in pairs or individually when working on the graphic organizer. If you do not want to use the organizer, students can draw a diagram and label the layers. The students can then describe the structure and function of each of the vessel layers. When students are looking at pictures of the blood vessels you can discuss them together as a class. Extension Students and/or teacher can bring in materials for the organizer to model each of the layers. (Example: elastic for elastic layer in media or netting for the epithelial layer.)
