2. ❓ Why is balancing chemical reactions important for conservation of mass?

3. ❓ What are common challenges when balancing chemical equations?

4. ❓ How can the trial-and-error method help in balancing reactions?

5. ❓ Did anyone find an interesting example of a chemical reaction during their research that they would like to share?

Development

Duration: 75 - 85 minutes

The purpose of this stage is to provide a practical and engaging experience where students apply their knowledge of balancing chemical reactions in playful and technological activities. This allows them to consolidate their learning in a contextualized and fun way while developing collaborative and creative skills.

Activity Suggestions

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

Activity 1 - 🌟 Unraveling the World of Reactions with TikTok 🌟

> Duration: 60 - 70 minutes

- Objective: Apply knowledge about balancing chemical reactions in a practical and creative way, using popular digital technologies among students.

- Description: In this activity, students will create creative TikTok-style videos to explain and demonstrate the balancing of chemical reactions. Each group will choose a specific chemical reaction, balance the equation, and using visual and sound effects, present the process in a fun and educational way.

- Instructions:

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

• Each group will choose a specific chemical reaction from the options provided by the teacher.

• Students must balance the chemical reaction using the trial-and-error method.

• After balancing, groups should create a storyboard to plan the TikTok video, including visual and sound elements.

• Using their phones, students will record the explanatory video, highlighting the balancing of the reaction and the importance of the process.

• Videos should be between 1 and 2 minutes long and should be edited directly on their phones using video editing apps.

• Once completed, the videos will be shared on an online platform (like Google Classroom) for the whole class to watch.

Activity 2 - 👾 Gamification: Balancing Challenge 👾

> Duration: 60 - 70 minutes

- Objective: Foster the skill of balancing chemical reactions through a competitive and collaborative environment that utilizes gamification elements to engage students.

- Description: Students will participate in a competitive online game where they will balance different chemical equations. Using a gamification software, each group will face progressive challenges, accumulating points as they correctly balance the equations.

- Instructions:

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

• Each group will access a gamification platform (like Kahoot, Socrative, or Quizizz), where they will encounter balancing challenges.

• Students will collaboratively solve each challenge using the trial-and-error method and record their answers in the gamification software.

• The software will tally each group's points based on the accuracy and speed of the answers.

• Groups will compete against each other in multiple rounds, with challenges becoming progressively more difficult.

• At the end of the activity, the groups with the highest scores will be recognized and will have the opportunity to explain how they arrived at their answers.

Activity 3 - 🧪 Scientific Influencers on Instagram 🧪

> Duration: 60 - 70 minutes

- Objective: Incorporate chemistry content into a practical activity that leverages social media to create an interactive and visual learning environment.

- Description: In this activity, students will create a series of Instagram posts simulating being digital science influencers. Each group will choose a chemical reaction, balance the equation, and create explanatory and visual posts to educate their followers about the topic.

- Instructions:

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

• Each group will select a chemical reaction from a list provided by the teacher.

• Students should balance the chemical reaction using the trial-and-error method.

• Create a content plan for a series of Instagram posts, including images, graphs, and short informative descriptions.

• Using free graphic design tools (such as Canva), students will create visual content for their posts.

• Each group will make at least 3 explanatory posts, exploring the balancing process and the importance of mass conservation in chemical reactions.

• The posts will be shared on an online platform (like Google Classroom or a class blog) for all students to view and comment.
