• Each puzzle must be solved in sequence for students to advance to the next challenge.

• Include problems calculating the mass ratios of elements and analysis of chemical compounds.

• Students must collaborate to solve each puzzle and input the correct answer on the platform to unlock the next challenge.

• The teacher should monitor the progress of the groups and provide hints if necessary.

• At the end, all groups will gather to discuss the solutions to the puzzles and revisit the concepts of Dalton's Law.

Activity 3 - 🎮 Gamification: Journey of the Elements

> Duration: 60 to 70 minutes

- Objective: Foster playful and collaborative learning through gamification, allowing students to apply Dalton's Law in different contexts and situations.

- Description: Students will be divided into groups and participate in a digital board game where they must follow a journey to complete chemical reactions based on Dalton's Law. Using online game creation tools, students will face challenges and learn about the formation of chemical compounds.

- Instructions:

• Divide students into groups of no more than 5 people.

• Use an online platform (like Google Slides, Jamboard, or another game creation tool) to create a digital board game.

• Each space on the board should present a challenge or question related to Dalton's Law.

• Students must progress through the board by answering questions and completing challenges to form chemical compounds.
