By researching interesting facts about calorimetry, students become more engaged and motivated to deepen their knowledge. The key questions help review previously studied content and lay the groundwork for the practical activities to follow.

Warming Up

Introduce the topic of the lesson by explaining that calorimetry is the science that studies heat exchanges between bodies or systems, and how these exchanges influence changes in state and temperature. Then, ask students to use their phones to look up an interesting fact about calorimetry. They should share the information they find in the classroom.

Initial Reflections

1. What is calorimetry and what is its importance in Physics?

2. How do heat exchanges occur between different materials?

3. What are the main factors that influence the amount of heat exchanged?

4. What is equilibrium temperature and how is it achieved?

5. How do changes in state (such as melting and vaporization) relate to heat exchanges?

Development

Duration: 70 - 80 minutes

The purpose of this stage of the lesson plan is to provide students with an opportunity to apply their knowledge practically and contextually through digital and collaborative activities. By engaging in real-world problem scenarios and using modern technologies, students become protagonists of their learning, reinforcing physical concepts while developing digital and teamwork skills.

Activity Suggestions

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

Activity 1 - 🕵️‍♂️ Digital Investigators: The Case of the Cold Drinks 🥤

> Duration: 60 - 70 minutes

- Objective: Calculate the amount of ice needed to keep the temperature of drinks at an event, applying knowledge of heat exchanges and the use of digital tools.

- Description: In this activity, students take on the role of digital investigators and must solve a heat exchange problem involving cold drinks and ice cubes. They will use their online research skills and digital tools to find solutions and present their findings creatively.

- Instructions:

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

• Explain the scenario: A beverage company wants to know how much ice is needed to keep their drinks below 10°C during a 4-hour event. Each group must investigate and calculate this amount of ice.

• Guide students to use digital tools like Google Sheets to organize data and calculations.

• Ask the groups to create a digital presentation (like a slide in Google Slides or a short video) explaining step by step how they arrived at the solution.

• Each group should present their results and reasoning to the class.

• Encourage the use of memes and gifs related to the topic to make the presentations more engaging and playful.

Activity 2 - 🎮 Gamifying Calorimetry: Mission Melting 🔥❄

> Duration: 60 - 70 minutes

- Objective: Apply concepts of heat exchanges in a gamified context, simulating the management of an ice cream factory and using digital technologies for data collection and presentation.

- Description: Students will participate in a simulation game where they must manage an ice cream factory. They will use a simulation app to learn about the heat exchanges necessary to keep ice creams frozen during transport and storage.

- Instructions:

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

• Instruct students to download and open the simulation app (the teacher should choose a suitable app in advance, such as 'Thermodynamics Simulation App').

• Each group must simulate managing an ice cream factory, adjusting variables such as the amount of dry ice and freezer temperature.

• During the game, students should note the data and results obtained in each simulated scenario.

• Ask each group to create a digital report (using Google Docs) that describes their experiences, observations, and conclusions on how to optimize the use of dry ice to minimize heat loss.

• Each group should share their report on a digital platform (like Google Classroom) and make a brief presentation about their findings.

Activity 3 - 💡 Physics Influencers: The #CalorimetryChallenge 🔥❄

> Duration: 60 - 70 minutes

- Objective: Utilize social media to creatively and engagingly teach calorimetry concepts, developing digital communication skills and practical knowledge application.

- Description: Students will turn into digital influencers and create content for social media explaining concepts of calorimetry. They should use videos, stories, and posts to engage their followers and explain heat exchange problems.

- Instructions:

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

• Explain that each group will be responsible for creating a campaign on a social network (such as Instagram or TikTok) to teach calorimetry concepts.

• Students should create a series of digital content, including short videos, stories, and illustrative posts that explain heat exchange problems and solutions.

• Encourage students to use hashtags like #CalorimetryChallenge or #EngagingPhysics to increase the reach of their campaign.

• Groups should share their content on social media and collect feedback from their followers.

• In the end, each group will make a presentation to the class showcasing the content created and discussing the impact and engagement generated.

Feedback

Duration: 15 - 20 minutes

The purpose of this stage is to consolidate learning through reflection and sharing experiences. By discussing in groups and providing mutual feedback, students have the opportunity to review concepts, identify strengths and areas for improvement, as well as develop communication and teamwork skills.

Group Discussion

Promote a group discussion with all students, where each group shares their experiences and conclusions from the activities conducted. Use the following script to introduce the discussion: 'Now that all groups have completed their activities, let's share what we learned. Each group will have 5 minutes to present the main results and reflections on the activity. Let’s start with Group 1.'

Reflections

1. What were the biggest challenges you faced while solving heat exchange problems? 2. How did the use of digital tools help or hinder the solution of the problems presented? 3. What did you learn about the importance of heat exchange in everyday situations, such as keeping a drink cold or storing frozen foods?

360° Feedback

Conduct a 360° feedback stage where each student should receive feedback from their group peers. Guide students to provide constructive and respectful feedback, focusing on positive points and suggestions for improvement. Use the following guide: 'Each group member should spend 1 minute providing feedback to their peer. Remember to be respectful and constructive, highlighting what the person did well and suggesting areas for improvement.'
