- Instructions:

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

• Each group should choose a name and create a visual identity for their digital influencer profile.

• Using digital tools (like Canva, Instagram, or an online blog), groups will create a series of posts that explain stoichiometry in a creative and accessible manner.

• The posts should include: theoretical introductions, step-by-step stoichiometric calculations, everyday practical examples, and curiosities.

• Each group must also create at least one short video (up to 2 minutes) where they present one of the concepts or solve a problem live.

• At the end, the groups will share their posts with the class and explain their approaches.

Activity 2 - Chemistry Game Show 🎮

> Duration: 60 to 70 minutes

- Objective: Promote the resolution of stoichiometry problems in a playful manner, using digital platforms and encouraging collaboration and healthy competition among students.

- Description: Students will participate in a live game show, where they will solve stoichiometry problems to earn points. The activity will use an online quiz platform, such as Kahoot or Quizizz, to promote competition and learning.

- Instructions:

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

• Explain that they will participate in a live game show and that each group will need to collaborate to solve stoichiometry problems faster than the competitors.

• Using the chosen platform, create a series of multiple-choice questions and practical problems involving stoichiometric calculations.

• Each group must have a device (cell phone or computer) to answer the questions on the platform.

• During the game show, groups will solve the problems and enter their answers on the platform. There will be a time limit for each question.

• At the end, the group with the most points will be the winner and will receive a prize (it can be something symbolic, like a digital certificate).

Activity 3 - Space Mission: Stoichiometry in Action 🚀

> Duration: 60 to 70 minutes

- Objective: Demonstrate the practical application of stoichiometry in high technology and engineering contexts, developing problem-solving and teamwork skills.

- Description: Students will be transformed into chemical engineers working for a space agency. They will have to solve a series of stoichiometry problems to ensure the success of a space exploration mission.

- Instructions:

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

• Explain that each group is a team of chemical engineers responsible for different aspects of a space mission.

• Provide each group with a set of stoichiometry problems related to the mission, such as calculating the amount of fuel needed, producing oxygen on board, or synthesizing new materials.

• Groups should use digital tools, such as online simulators and chemical calculators, to solve the problems.

• Each group will present their solutions, explaining how they arrived at the results and their importance for the space mission.

• At the end, there will be a group discussion about how stoichiometry is vital for science and space engineering.

Feedback

Duration: 15 to 20 minutes

🎯 Purpose: The purpose of this stage is to consolidate learning through sharing experiences and reflections, promoting knowledge exchange and the development of communication and self-assessment skills. This phase also helps to promote a collaborative environment, where students learn to value their peers' opinions and reflect on their own performance.

Group Discussion

🗣️ Group Discussion: Start the discussion by inviting each group to share their experiences and learnings. Say: 'I would like each group to briefly present what they learned during the activities, highlighting the challenges encountered and the solutions developed. What were the most interesting or surprising parts for you?'. Encourage students to ask each other questions and complement the presentations with their own observations.

Reflections

1. 🔍 Reflection Questions: How does stoichiometry relate to our daily lives and the technologies we use every day? 2. 📊 Reflection Questions: What were the main difficulties encountered during the stoichiometric calculations and how did you overcome them? 3. 🌐 Reflection Questions: How did digital tools facilitate the learning and practice of stoichiometry concepts?

360° Feedback

🔄 360° Feedback: Explain to students the importance of giving and receiving feedback constructively. Instruct them to focus on positive aspects and areas for improvement. Say: 'Now, each group member should provide brief and respectful feedback on their colleagues' performance. Think of something they did well and something they could improve on. Remember to be specific and kind.'

Conclusion

Duration: 10 to 15 minutes
