Chapter Name: Movements in Animals
Activity Name: The ribs in Movements in Animals
The experiment aims to help students understand the structure and function of ribs and the rib cage. Students will be asked to take a deep breath and feel their chest bones to count the number of ribs.
They will also observe the curved shape of the ribs and learn how they connect the chest bone and the back bone, forming a protective rib cage. Students will be prompted to guess the important internal organs that lie inside the rib cage.
Step by Step Procedure:
- Instruct the students to take a deep breath and hold it for a little while.
- Ask them to place their hands on the middle of their chest, gently pressing down.
- Encourage them to feel their chest bones and try to count as many ribs as possible.
- Guide the students to observe the curved shape of the ribs.
- Explain that the ribs connect the chest bone (sternum) and the back bone (vertebrae), forming a box-like structure called the rib cage.
- Facilitate a discussion by asking students to guess what important internal organs are protected inside the rib cage.
- Allow students to share their guesses and encourage them to think about organs like the heart, lungs, and certain blood vessels that lie within the rib cage.
- Discuss the significance of the rib cage in protecting these vital organs.
- Students will observe the curved shape of the ribs.
- They will count the number of ribs they can feel.
- They will discuss and guess the important internal organs protected by the rib cage.
- Ensure that students are gentle when pressing their chest to avoid any discomfort or injury.
- Emphasize that this experiment is for observation only and should not involve excessive pressure or force on the chest.
Lesson Learnt from Experiment:
Through this experiment, students learn that the rib cage plays a crucial role in protecting vital organs such as the heart, lungs, and certain blood vessels.
They understand the structural arrangement of ribs and their connection to the chest bone and the back bone. This activity helps students develop a basic understanding of the skeletal system and its importance in safeguarding internal organs.
