Objectives

Duration: 10 - 15 minutes

This stage aims to present the main objectives of the lesson, highlighting the importance of understanding weather forecasting and its key variables. This is essential for developing practical skills that are highly valued in the job market, such as the ability to interpret meteorological data and make informed decisions based on it.

Main Objectives

1. Understand how weather forecasting works.

2. Identify important variables for weather forecasting, such as relative humidity and air mass movement.

Side Objectives

1. Relate the acquired knowledge to practical application in the job market.

Introduction

Duration: 15 - 20 minutes

This stage aims to introduce the topic of weather forecasting, creating a connection with everyday and professional situations. By sparking students' curiosity and demonstrating the practical relevance of the subject, engagement and understanding of the concepts to be explored in the lesson are facilitated.

Contextualization

Weather forecasting is an essential tool in our daily lives. It helps us plan our activities, from knowing if we need to bring an umbrella to deciding the best time for planting and harvesting in agriculture. Understanding how weather forecasts are made may seem complicated, but it is a practical and valuable skill that influences various areas of our lives.

Curiosities and Market Connection

Did you know that meteorologists use supercomputers to analyze large volumes of data and forecast the weather? Moreover, professionals in aviation, agriculture, construction, and tourism rely on accurate weather forecasts for critical decision-making. For example, farmers use weather data to optimize irrigation and increase crop productivity.

Initial Activity

• Provocative question: "How do you think meteorologists manage to predict if it will rain or be sunny in the coming days?"
• Short video: Show a 3-minute video that illustrates how weather forecasts are made, from data collection to dissemination in the media.

Development

Duration: 60 - 65 minutes

This stage aims to deepen students' knowledge about weather forecasting through practical and experimental activities. By building meteorological instruments and reflecting on their applications, students develop relevant technical skills and better understand the variables that influence the climate.

Covered Topics

1. Meteorological Variables: relative humidity, temperature, atmospheric pressure, wind speed and direction
2. Air mass movement: cold air and warm air
3. Measuring instruments: thermometer, barometer, hygrometer, anemometer
4. Forecast models: how they are created and used

Reflections on the Theme

Guide students to reflect on how weather forecasting can impact their daily lives and professions. Ask them about the importance of predicting extreme weather events, such as storms and heatwaves, and how these forecasts can help save lives and protect property.

Mini Challenge

Building a Homemade Weather Station

Students will build a weather station using simple materials. The station will include a thermometer, hygrometer, barometer, and anemometer. This activity will allow them to practically understand how meteorological variables are measured.

Instructions

1. Divide the class into groups of 4 to 5 students.
2. Distribute the necessary materials: plastic bottles, alcohol, water, balloons, straws, adhesive tape, scissors, plastic cups, cardboard, among others.
3. Each group should follow the instructions to build the meteorological instruments:
4. Thermometer: Fill a plastic bottle with a mixture of water and alcohol, insert a straw through a balloon placed at the mouth of the bottle, and seal the bottle with adhesive tape.
5. Barometer: Fill a plastic cup halfway with water, place another cup upside down inside the first cup and observe the changes in the water level.
6. Hygrometer: Use a strip of cardboard and a piece of human hair to measure humidity. The hair expands and contracts based on the humidity.
7. Anemometer: Construct with four plastic cups fixed in a cross on a rotating base to measure wind speed.
8. After building, each group should present their instruments to the class, explaining how they work and what variables they measure.

Objective: Allow students to experience firsthand how meteorological instruments work and to understand how measurements of climate variables are made.

Duration: 40 - 45 minutes

Evaluation Exercises

1. Explain how relative humidity can influence weather forecasting.
2. Describe the process of cold air mass formation and how it affects the climate of a region.
3. List the studied meteorological instruments and their respective functions.
4. Discuss the importance of weather forecasting models and how they are utilized in different professional sectors.

Conclusion

Duration: 15 - 20 minutes

This stage aims to consolidate students' learning, reinforcing the concepts addressed during the lesson and promoting reflection on the practical application of the knowledge acquired. By summarizing the main points and connecting theory to practice, students are encouraged to see the relevance of the subject in their daily lives and future careers.

Discussion

Facilitate a discussion among the students about the experience of building the homemade weather station. Ask what they found most challenging and what they learned about meteorological variables during the construction and use of the instruments. Encourage students to reflect on how weather forecasts can impact professions and daily activities, such as agriculture, aviation, and tourism. Ask how they think technology and science can continue to evolve to improve the accuracy of weather forecasts.

Summary

Summarize the main contents addressed in the lesson, highlighting the importance of meteorological variables such as relative humidity, temperature, atmospheric pressure, and air mass movement. Reinforce how the meteorological instruments built in class, such as the thermometer, barometer, hygrometer, and anemometer, allow measuring these variables and understanding climate better.

Closing

Explain how the lesson connected theory with practice by allowing students to build weather instruments and apply the acquired knowledge. Emphasize the relevance of weather forecasts in daily life and various professions, and how the ability to interpret meteorological data is valuable and applicable in different contexts. Conclude by highlighting the importance of continuous study and scientific curiosity to face future climate challenges.
