Side Objectives:

Introduction

Duration: (15 - 20 minutes)

This stage of the introduction is designed to engage students through problem-based situations that make them think critically about the practical application of temperature in their daily lives. Furthermore, by contextualizing the importance of the study of temperature with curiosities and connections to real life, students can see the practical value of this knowledge and how it applies in various situations. This aims to reinforce understanding and relevance of the topic, preparing students for the practical activities that will follow.

Problem-Based Situations

1. Imagine you are preparing a recipe that needs to be cooked at a specific temperature. How would you adjust the oven if the recipe is in Fahrenheit and your oven shows only Celsius?

2. Think of a very cold winter day. If the thermometer shows -5°C, what does that mean in terms of how you should dress and what to expect when leaving the house?

Contextualization

Temperature affects many aspects of our daily lives, from deciding what to wear to how we store food in our homes. Knowing different units of measure for temperature, such as Celsius and Fahrenheit, is crucial not only in the kitchen but also in many other areas, including science and meteorology. Did you know that Daniel Gabriel Fahrenheit, a German physicist, created the Fahrenheit scale in 1724? And that Anders Celsius, a Swedish astronomer, proposed the Celsius scale in 1742, which is now the most widely used in the world, except in the United States?

Development

Duration: (75 - 80 minutes)

The Development phase is designed to put students' prior knowledge of temperature units into practice, with an emphasis on degrees Celsius. The proposed activities aim to engage students in practical and fun tasks that require critical use of the acquired knowledge. This stage is crucial for solidifying students' understanding through practical application in scenarios that simulate real situations, thus promoting significant and lasting learning.

Activity Suggestions

It is recommended to carry out only one of the suggested activities

Activity 1 - Thermometric Treasure Hunt

> Duration: (60 - 70 minutes)

- Objective: Practice conversion between Celsius and Fahrenheit scales and understand the practical application of temperature units in everyday life.

- Description: In this playful activity, students will be divided into groups, and each group will receive a map of the 'thermometric treasure'. The map contains several stations scattered around the classroom, where each station represents an everyday situation with a certain temperature value that must be converted between Celsius and Fahrenheit. Students will need to solve problems to unlock clues that will lead them to the final 'treasure', which may be a symbolic prize related to the theme.

- Instructions:

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

• Give each group a map with the stations marked.

• Each station has a temperature conversion problem that needs to be solved to obtain the next clue.

• Students must record their answers and conversions on an answer sheet.

• The first group to solve all the problems and reach the treasure wins a symbolic prize.

Activity 2 - The Exact Chef

> Duration: (60 - 70 minutes)

- Objective: Develop mathematical skills through temperature conversion and improve presentation and explanation skills.

- Description: Students, in groups, will take on the role of chefs in a fictional cooking contest. They will need to adjust the temperature of various recipes that are in Fahrenheit to Celsius, using thermometers and calculating the correct conversion to ensure that the dishes are cooked perfectly. Each group will present their adjusted recipe and explain how they arrived at the correct temperatures.

- Instructions:

• Organize the room into 'kitchens' where each group has its own space to work.

• Distribute recipes with temperatures in Fahrenheit.

• Students must calculate the conversion to Celsius and adjust their 'kitchens' accordingly.

• Each group must present their recipe and explain the temperature conversion process used.

• Evaluate the presentations based on the accuracy and clarity of the explanations.

Activity 3 - Little Meteorologists

> Duration: (60 - 70 minutes)

- Objective: Understand the importance of temperature in different geographical contexts and practice conversion between Celsius and Fahrenheit.

- Description: Students will create a 'weather journal', where each group will be responsible for presenting the weather forecast for different cities around the world. They will need to convert temperatures from Celsius to Fahrenheit and vice-versa, creating an informational bulletin that includes this information, as well as recommendations for appropriate clothing for each climate.

- Instructions:

• Divide students into groups and assign each group a few cities.

• Provide temperature data in one of the scales and ask them to convert it.

• Students should create a weather bulletin in video or poster form.

• Include in the bulletin clothing recommendations based on the converted temperatures.

• Each group presents their bulletin to the class.

Feedback

Duration: (10 - 15 minutes)

The purpose of this stage is to allow students to reflect on their learning and verbalize their understandings and difficulties. This not only reinforces the knowledge acquired but also allows them to share different perspectives and solutions found, promoting a collective and in-depth learning experience. Additionally, it will help the teacher assess the effectiveness of the activities and the students' understanding of the topic of temperature.

Group Discussion

To start the group discussion, lead all students to gather in a circle. Begin by reflecting on the activities carried out and ask how they felt applying their knowledge in practical situations. Encourage each group to share their discoveries and most significant experiences during the activities. Promote an open environment where students can express what they learned and what challenges they faced.

Key Questions

1. What were the biggest difficulties encountered when converting temperatures between the Celsius and Fahrenheit scales?

2. How would you apply knowledge about temperature and its conversions in your daily life?

3. Which activity did you find the most challenging and why?
