Lesson Plan | Active Learning | Human Body: Skeletal System

Assumptions: This Active Lesson Plan assumes: a 100-minute class, prior student study with both the Book and the start of Project development, and that only one activity (among the three suggested) will be chosen to be conducted during the class, as each activity is designed to take up a significant portion of the available time.

Objectives

Duration: (5 - 10 minutes)

The objectives stage is essential for directing students' focus to the critical aspects of the skeletal system. Through a clear description of the objectives, students will be able to understand what is expected of them and how the class will contribute to the development of their knowledge of anatomy and physiology. This section also serves to establish a solid foundation for the practical activities that will follow, ensuring that students apply what they have learned effectively and meaningfully.

Main Objectives:

1. Describe the components of the skeletal system and their main functions, highlighting the importance of each part for the support and movement of the human body.

2. Analyze the interaction of the skeletal system with other systems of the human body and how it contributes to homeostasis and overall health.

Side Objectives:

1. Identify and differentiate the types of bones (long, short, flat, and irregular) and their locations in the human body.

Introduction

Duration: (10 - 15 minutes)

The introduction serves to engage students with the content they studied previously, using problem situations that stimulate the practical application of the knowledge acquired about the skeletal system. Additionally, by contextualizing the importance of the skeletal system with real examples and curiosities, students can perceive the relevance of the topic in their lives and in society, encouraging a more active and meaningful learning experience.

Problem-Based Situations

1. Imagine that an astronaut returns from a long mission in space. He reports difficulties in adapting to Earth's gravity, especially in walking and moving his arms. How might the skeletal system be affecting these basic functions of the astronaut after his stay in space?

2. Consider an athlete who injures his ankle during a game. Even though there is no fracture, the ankle remains painful and limits his movements. How can your knowledge of the skeletal system help understand the possible affected structures and the types of treatment that can be applied?

Contextualization

The skeletal system is not just a set of bones, but a dynamic system that plays vital roles in support, movement, and protection of the human body. Interestingly, the skeletal system has evolved to support Earth’s gravity and allow complex mobility, adapting to different environments over millions of years. Moreover, osteoporosis, a condition that weakens bones, affects millions of people globally, highlighting the relevance of understanding the skeletal system for public and individual health.

Development

Duration: (75 - 80 minutes)

The Development stage is designed to allow students to apply the knowledge acquired about the skeletal system in a practical and interactive way. Using methods that encourage collaboration, critical thinking, and creativity, students can solidify their theoretical understanding through practice. The activities are designed to be both educational and fun, ensuring that students remain engaged and motivated throughout the process.

Activity Suggestions

It is recommended to carry out only one of the suggested activities

Activity 1 - Skeletons in Action

> Duration: (60 - 70 minutes)

- Objective: Understand the structure and function of bones in a practical and interactive way, reinforcing knowledge of the skeletal system.

- Description: Students will be divided into groups of up to 5 people. Each group will be tasked with creating a life-size human skeleton using recyclable materials such as newspapers, popsicle sticks, and tape. The skeleton must be able to stand and simulate basic movements such as walking, sitting, and raising arms. Each bone must be identified with its name on an attached paper.

- Instructions:

• Divide the room into groups of up to 5 students.

• Distribute recyclable materials to each group.

• Instruct students to quickly research the position and name of the main bones in the human body.

• Guide students in constructing the skeleton, encouraging creativity in the use of materials.

• Allow time for each group to present their skeleton and explain the function of each bone.

Activity 2 - Bone Detectives

> Duration: (60 - 70 minutes)

- Objective: Apply theoretical knowledge to diagnose problems in the skeletal system and understand the importance of the system in health and wellness contexts.

- Description: In this activity, groups of students will receive patient files with descriptions of symptoms and medical histories indicating possible problems in the skeletal system. Students will need to use their knowledge to diagnose which part of the skeletal system is affected and how it can be treated.

- Instructions:

• Form groups of up to 5 students.

• Distribute patient files with descriptions of health problems related to the skeletal system.

• Allow students to discuss in groups and use research resources to help with the diagnosis.

• Each group should present their diagnoses and the recommended treatment, justifying based on the symptoms and the anatomy of the skeletal system.

Activity 3 - Bone Bridge Builders

> Duration: (60 - 70 minutes)

- Objective: Understand the importance of bone structure in support and locomotion, applying concepts of engineering and physics in the construction of a practical representation.

- Description: Students, in groups, will need to build a bridge using uncooked pasta and glue. The structure of the bridge should simulate the strength and support of bones, being capable of holding a specific weight. The final challenge will be to test the bridge to see how many cars (light weights) it can support.

- Instructions:

• Divide the class into groups of up to 5 students.

• Distribute uncooked pasta, glue, and light weights to each group.

• Challenge students to design and build a bridge that is strong and light.

• Test the constructed bridges to see which group can support the greatest number of weights without collapsing.

Feedback

Duration: (15 - 20 minutes)

The purpose of this stage is to allow students to articulate what they have learned and how they applied theoretical knowledge in practical situations. The group discussion helps reinforce learning, allowing students to see different approaches and solutions to the same problems. Furthermore, this exchange of experiences and ideas promotes a deeper understanding of the topic, encouraging collaborative and critical learning.

Group Discussion

To start the group discussion, the teacher should first gather all the students and explain the importance of reflecting on the practical activities undertaken. Then, each group is asked to share their main discoveries and challenges faced during the construction of the skeletons, the diagnosis of health issues, and the engineering of the bone bridges. The teacher should facilitate the discussion, ensuring that all groups have the opportunity to speak and encouraging questions and comments among peers.

Key Questions

1. What were the main difficulties encountered while constructing the skeleton, and how did you overcome them?

2. How do the diagnosed health problems reflect the importance of knowledge of the skeletal system in medicine?

3. In what way does the bone bridge activity relate to the support and movement of the human body?

Conclusion

Duration: (5 - 10 minutes)

The purpose of the Conclusion stage is to consolidate learning, ensuring students have a clear and integrated understanding of the topics discussed. Additionally, it aims to reinforce the link between theory and practice, showing students the applicability of the acquired knowledge and encouraging a proactive attitude towards taking care of their own bodies and seeking continuous knowledge about anatomy and physiology.

Summary

In this conclusion stage, the teacher should summarize and recapitulate the main points addressed regarding the skeletal system, emphasizing the structure and function of bones, as well as their importance for the movement and support of the body. It is essential to revisit the types of bones (long, short, flat, and irregular) and their specific functions, ensuring that students have consolidated this knowledge.

Theory Connection

During the class, students were able to connect the theory studied with interactive practices, such as constructing skeletons and bone bridges and simulating medical diagnoses. These activities not only solidified theoretical understanding but also showcased real and practical applications of skeletal system knowledge in various contexts, from medicine to engineering.

Closing

Finally, the teacher should highlight the importance of the skeletal system for health and well-being, briefly discussing how the knowledge acquired can be applied in daily life to promote a better understanding of the human body and the prevention of injuries. This final reflection serves to reinforce the relevance of continuous learning about anatomy and physiology.
