1. SHBI1P3D1PK1 Human Body Investigation 1 Bones Part 3 – Owl Pellets Day 1

2. SHBI1P3D1PK2 Enduring Understanding Living systems demonstrate the complementary nature of structure and function. This means that the way we use our body is related to how our body is constructed.

3. SHBI1P3D1PK3 Essential Question How does structure relate to function in living systems? We will be able to describe how bones, muscles, and joints function together in humans to enable movement, protection and support

4. SHBI1P3D1PK4 Science Vocabulary bones – the individual parts of a hard interior framework that provide shape and protection for the human body. cartilage – the rubbery, flexible material that sometimes connects bones and provides shape for some body parts, including the nose and ears. joint – the place where two bones meet.

5. SHBI1P3D1PK5 Science Vocabulary skeleton – the system that includes all of the bones in the body skull – the hollow case, made from 18 fused bony plates and 2 jaw bones, that surrounds and protects the brain, inner ears, and eyes. torso – the main part of the body, including shoulders, chest, abdomen, and hips. ribs – the parts of the body that protect the heart and lungs

6. SHBI1P3D1PK6 What We Will Learn How the bones of rodents are like those of humans. How the bones of rodents are different from those of humans. The function of a bone can be determined by its structure.

7. SHBI1P3D1PK7 Introduce Owl Pellets Introduce this part by reading Barn Owls with the class. Explain that students are going to investigate the bones of a small animal found in an owl pellet. Owls eat small rodents but cannot digest the fur and bones. The owl then coughs up or regurgitates a pellet containing the bones.

8. SHBI1P3D1PK8 Procedure Students work in teams of two. Unwrap the foil and remove the pellet. Observe the whole pellet. Notice the shape, color and texture of the pellet. Write and draw your observations on the Owl- Pellet Observation sheets. Gently separate the pellet into two pieces, so that each student has a piece to examine.

9. SHBI1P3D1PK9 Procedure Separate the bones from the fur and other material using your fingers or toothpicks as probes.

10. SHBI1P3D1PK10 Record Observations Discard the fur and other material when the bones have been separated. Note the size, shape, and number of bones.

11. SHBI1P3D1PK11 Discussion How are these animal bones similar to human bones? How are these animal bones different from human bones?

12. SHBI1P3D1PK12 Science Vocabulary Review bones – the individual parts of a hard interior framework that provide shape and protection for the human body. cartilage – the rubbery, flexible material that sometimes connects bones and provides shape for some body parts, including the nose and ears. joint – the place where two bones meet.

13. SHBI1P3D1PK13 Science Vocabulary skeleton – the system that includes all of the bones in the body skull – the hollow case, made from 18 fused bony plates and 2 jaw bones, that surrounds and protects the brain, inner ears, and eyes. torso – the main part of the body, including shoulders, chest, abdomen, and hips. ribs – the parts of the skeleton that protect the heart and lungs

14. SHBI1P3D1PK14 What We Learned Today and Will Continue to Learn About Tomorrow How the bones of rodents are like those of humans. How the bones of rodents are different from those of humans. The function of a bone can be determined by its structure.
