Activity Suggestions

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

Activity 1 - 🎬 Creating a Scientific Vlog 🎥

> Duration: 60 - 70 minutes

- Objective: Allow students to explain physics concepts creatively and engagingly, using digital and collaborative skills to convey knowledge.

- Description: Students will create a vlog where they explain and demonstrate, using practical experiments, the differences in vibration between open and closed tubes. They should address concepts like harmonics and steady state, using storytelling elements to make the explanation more engaging.

- Instructions:

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

• Each group should choose a leader and someone responsible for recording and editing.

• Research practical examples of sound tubes (e.g., musical instruments) and prepare a script for the vlog.

• Record the explanations and experiments, highlighting the differences between open and closed tubes, harmonics, and steady state.

• Edit the video, adding introductions, soundtracks, and subtitles to enhance understanding.

• Each group must publish the vlog on YouTube or another video platform and share the link with the class.

Activity 2 - 📱 Scientific Social Media 🌐

> Duration: 60 - 70 minutes

- Objective: Facilitate the understanding of physics concepts through a language accessible and familiar to students, promoting interaction and discussion in a collaborative environment.

- Description: Students will use a fictional social network to create posts and stories explaining the concepts of vibration in sound tubes. They must interact with each other in the comments, answering questions and discussing more complex aspects of the topic.

- Instructions:

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

• Each group should meet and discuss the main concepts about vibration in sound tubes.

• Create a series of posts and stories, simulating publications in a social network, with images, short videos, explanatory texts, and polls about different types of tubes (open and closed), harmonics, and steady states.

• Use relevant hashtags and comment on classmates' posts, encouraging knowledge exchange and constructive discussions.

• The posts and stories can be created in Google Slides or using graphic editing apps on cell phones.

Activity 3 - 🎮 Digital Harmonics Game 🕹️

> Duration: 60 - 70 minutes

- Objective: Promote learning through gamification, allowing students to absorb physics concepts dynamically and interactively while developing digital and programming skills.

- Description: Students will develop a simple digital game where they must solve challenges related to vibrations in sound tubes to advance to the next level. They can use platforms like Scratch or Tynker to create the game, incorporating questions and mini-tests on the topic.

- Instructions:

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

• Each group should plan the game's concept, including phases that explain different aspects of vibrations in sound tubes, like open and closed tubes, harmonics, and steady state.

• Use platforms like Scratch or Tynker to develop the game, integrating questions, puzzles, and challenges related to the topic.

• Test the game among group members to ensure all phases are working correctly.

• Share the game with the class and allow everyone to play and learn from the proposed challenges.

Feedback

Duration: 20 - 30 minutes

🎯 Purpose: The goal of this stage is to promote critical reflection on learning, consolidating the discussed concepts. The group discussion and 360° feedback encourage knowledge exchange, collaboration, and self-valuation among students, creating a richer and more inclusive learning environment. This stage allows students to evaluate both the content and the learning process, strengthening their communication and critical thinking skills.

Group Discussion

🎤 Group Discussion: Facilitate a group discussion with all students. Each group should share what they learned while completing the proposed activities (scientific vlog, scientific social media, and digital game). Use the following outline to introduce the discussion:

1. Introduction (5 minutes): Ask a representative from each group to briefly summarize the activities they carried out and the main concepts learned.
2. Concept Discussion (10 minutes): Ask students about the differences between open and closed tubes, how harmonics relate to tube length, and practical examples of steady state.
3. Practical Applications (10 minutes): Ask groups to discuss how the concepts learned can be applied in everyday life, especially in modern technologies and musical instruments.

Reflections

1. 🧠 Reflection Questions:

1. How does vibration in open tubes differ from vibrations in closed tubes, and how does this reflect in sound production?
2. What challenges did your group face in explaining the concepts of harmonics and steady state through practical activities?
3. How do you believe the use of digital tools (vlog, social networks, games) helped in understanding sound wave concepts?

360° Feedback

🔄 360° Feedback: Instruct students to conduct a 360° feedback session, where each student must receive feedback from other members of the group they worked with. Guide the class to provide constructive and respectful feedback, focusing on the following aspects:

1. Individual Contribution: Highlight how each member contributed to the success of the activities.
2. Collaboration and Communication: Assess how communication and collaboration were within the group.
3. Task Performance: Provide feedback on performance in specific tasks, such as recording, editing, research, and game development.

Suggest that feedback be initially written, allowing each student to reflect on what has been said before sharing verbally.
