Then, have them share their findings with the class, highlighting the practical relevance of the concept.

Initial Reflections

1. How would you define resultant force in your own words?

2. What are some everyday examples where resultant force is present?

3. What is the relationship between force, distance, and the angle in calculating work?

4. How does resultant force influence the movement of objects?

5. What are the formulas we use to calculate the work done by a force?

Development

Duration: 70 to 80 minutes

The purpose of this stage is to provide students with an opportunity to apply the concepts of resultant force and work in a practical, collaborative, and digital way. The proposed activities encourage creative exploration, the use of modern technologies, and connection with everyday life, fostering deeper and more engaging learning.

Activity Suggestions

It is recommended that only one of the suggested activities be carried out

Activity 1 - The Scientific Influencer 🌟

> Duration: 60 to 70 minutes

- Objective: Develop the ability to communicate scientific concepts in an accessible and practical way, using digital technologies and social networks to engage and educate.

- Description: In this activity, students will be divided into groups and act as digital science influencers. They must create a 3 to 5-minute video explaining the concept of resultant force and demonstrating a practical experiment that illustrates the calculation of work done by a force. The video must be published on a fictitious social network created through a free online platform, such as Padlet.

- Instructions:

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

• Each group must research a practical experiment that involves resultant force and work.

• Using cell phones and/or computers, students must record a video explaining the concept of resultant force, the chosen experiment, and the calculation of work done.

• Videos should be edited using free apps (like InShot or Adobe Spark) to add captions, visual and sound effects.

• Each group must publish their video on the fictitious 'social network' (Padlet) and watch the videos of other groups.

• Students should comment on their peers' videos, asking questions and providing constructive feedback.

Activity 2 - Gamification: Physics Adventure 🕹️

> Duration: 60 to 70 minutes

- Objective: Encourage cooperation and problem-solving in a playful and interactive manner, using gamification to increase engagement and understanding of the concepts of resultant force and work.

- Description: Create an online game where students need to solve problems related to resultant force and work to advance levels. Using platforms like Kahoot! or Quizizz, students work in groups to answer questions and complete challenges that involve everyday situations.

- Instructions:

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

• Create an online game using Kahoot! or Quizizz with questions and challenges about resultant force and work.

• Each group must access the game through cell phones or computers.

• Students discuss among themselves to solve each question and input the answer on the platform.

• With each level completed, a new, more complex challenge is presented, involving calculations and practical application of the concepts.

• At the end, all groups discuss the answers and strategies used to solve the problems.

Activity 3 - Scientific Poster Design 📊

> Duration: 60 to 70 minutes

- Objective: Develop skills in design and visual communication, as well as deepen the understanding of scientific concepts through the creation of digital educational materials.

- Description: Students will work in groups to create a digital poster explaining resultant force and the calculation of work done. Using online tools such as Canva or Google Slides, each group should illustrate and detail a practical experiment, including graphs, formulas, and explanations.

- Instructions:

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

• Each group must choose a practical experiment related to resultant force and work done.

• Using apps like Canva or Google Slides, students create a digital poster that illustrates and explains the experiment.

• The poster must include graphs, formulas, a description of the experiment, and the practical application of the concepts.

• Posters are shared with the class through a collaborative platform such as Google Classroom.

• Each group presents their poster to the class, highlighting the key aspects of the experiment and the concept studied.

Feedback

Duration: 20 to 25 minutes

The purpose of this stage is to provide an opportunity for students to reflect on their experiences, consolidate learning, and receive valuable feedback that can help them improve their collaboration and communication skills. This moment of reflection and assessment contributes to a deeper understanding of the concepts studied, as well as strengthening the ability to work in teams and give and receive constructive feedback.

Group Discussion

Start the group discussion by asking each group to briefly share their experience with the activity they performed. Use the following script to guide the discussion:

Ask each group to describe the experiment they chose and justify their choice. Request them to explain the main challenges they encountered while performing the activity and how they overcame them. Ask what were the main learnings and conclusions drawn from the activities performed. Encourage students to discuss how the concept of resultant force and the calculation of work can be applied in everyday situations or in other subjects.

Reflections

1. How did the practical experience help clarify the concept of resultant force and work in relation to the theory previously studied? 2. What digital skills did you develop or improve with these activities? 3. How can you apply the knowledge and skills acquired in situations outside the classroom?

360° Feedback

Instruct students to conduct a 360° feedback session, where each group member must receive feedback from their peers. Guide them to be specific in their comments, highlighting positive aspects and suggesting improvements constructively and respectfully. For example, when praising, mention specific behaviors or approaches that were effective. When suggesting improvements, do so gently and in a way that helps the peer grow and learn. Ensure that all students feel comfortable and respected during this dynamic.

Conclusion

Duration: 10 to 15 minutes

🎯 Purpose 🎯: The purpose of this stage is to consolidate learning in a light and practical way, connecting theoretical concepts with real and current situations. This helps students perceive the relevance of the content studied and to apply this knowledge in their daily lives, promoting meaningful and lasting learning.
