1. Essential Question: How do major organ systems work together in living organisms?
Standards:
GSES7L2b: Develop and use a conceptual model of how cells are organized into tissues, tissues into organs, organs into systems, and systems into organisms.
GSES7L2c: Construct an argument that systems of the body interasct with one another to carry out life processes.
Instructional Approach(s): The teacher should use the slide to introduce the essential question and the standards that align to the essential question

2. What systems of the body are used when walking, running, jumping, etc.?
Instructional Approach(s): The teacher should show the slide and ask the class, call on a student, or allow the students to work in pairs to identify the system of the body used when walking, running, jumping, etc?

3. What part of our body is most like the frame of a house shown in the picture? Why?
Instructional Approach(s): The teacher should pose the question to the class. Ask the class or call on students to respond to the questions. Hopefully students come up with the skeletal system because it provides the foundation or frame for our bodies.

4. Why Do We Have Bones?
Instructional Approach(s): The teacher should briefly gather a few student responses.

5. Skeletal System: Provides Support
Bones help hold your body up, just like the frame on a house
Instructional Approach(s): The teacher should present the information on the slide while the students record “provides support” on their graphic organizer as a “role/job” of the skeletal system

6. Skeletal System: Aids in Movement
Bones allow us to move
Joints are where two bones meet
Bones are connect to other bones by ligaments
Instructional Approach(s): The teacher should present the information on the slide while the students record “aids in movement” and any other important information as a “role/job” of the skeletal system

8. Joint: where two bones meet
Instructional Approach(s): The teacher should present the information on the slide

9. Skeletal System: Provides Protection
Our Rib Cage Protects the Organs inside of our Body
Instructional Approach(s): The teacher should present the information on the slide while the students record “provides protection” as a “role/job” of the skeletal system

10. Skeletal System: Blood Cell Production
New Blood Cells are made in the center of your bones called the marrow.
Instructional Approach(s): The teacher should present the information on the slide while the students record “blood cell production” and any other important information as a “role/job” of the skeletal system

11. What are Bones?
Instructional Approach(s): Just a transition slide

12. Parts of our Bones
Instructional Approach(s): The teacher should present the information on the slide. The students have the image on their graphic organizer page. Use the image to illustrate the various components of a bone.

13. Based on the diagram to the right, what would you guess is the difference between Compact Bone and Spongy Bone?
Instructional Approach(s): The teacher should present the question to the class. Ask for responses or call on specific students for possible answers. After a short period of time, click the mouse to reveal the answer.
Compact Bone is very dense and tough.
Spongy Bone is strong, but lightweight.

14. Skeletal System Provides Support Aids in Movement Provides Protection
Instructional Approach(s): The teacher should use the animated slide to review the roles/jobs of the skeletal system that students should have recorded on their graphic organizer
Provides Protection
Blood Cell Production

15. Skeletal System Analogies
The Skeletal System is to the Human Body as ____________ is to ____________.
How is the Skeletal System like a shield?
How is the Skeletal System like an engine?
How is the Skeletal System like a factory?
How is the Skeletal System like the poles or rope in a tent?
Make your own analogy for the Skeletal System.
Instructional Approach(s): The teacher should allow students to work as a class, individually, or in pairs to answer the questions. Give students about 5 minutes to answer the questions and then spend another minute or two sharing responses.
