Introduction

Duration: 15 - 20 minutes

The purpose of this stage is to introduce the topic engagingly, highlighting its practical relevance and stimulating students' interest. By connecting the content with real situations and applications in the job market, the goal is to motivate students to engage actively in the next stages of the class.

Contextualization

Atmospheric circulation, winds, and rains are fundamental phenomena that directly influence our daily lives, from planning outdoor activities to agriculture and water resource management. Understanding these phenomena allows us to forecast the weather, prepare for extreme weather events, and make informed decisions in various areas of the job market.

Curiosities and Market Connection

Did you know that weather forecasting is crucial for aviation, agriculture, and even sporting events? Meteorologists use knowledge about atmospheric circulation to predict storms and droughts, helping to minimize damage and optimize operations. Additionally, renewable energy companies, such as wind power, rely on understanding wind patterns to efficiently position turbines.

Initial Activity

To start the class in a dynamic way, present a short video (3-5 minutes) about a famous storm or an extreme weather event, such as Hurricane Katrina. After the video, ask the following provocative question to the students: 'How do you think meteorologists predicted this event and what atmospheric factors were considered?' Encourage a brief discussion based on the students' responses.

Development

Duration: 55 - 60 minutes

The purpose of this stage is to provide students with a practical and interactive experience that solidifies the theoretical concepts presented. The construction of the anemometer and the analysis of collected data allow students to understand atmospheric phenomena in an applied manner and their relevance to the job market. Additionally, fixation and evaluation exercises ensure that students can reflect on and consolidate the knowledge acquired.

Covered Topics

1. Atmospheric agents and their influence on climate
2. Atmospheric circulation: concept and influencing factors
3. Difference in temperature and pressure in the formation of winds
4. Process of rain formation

Reflections on the Theme

Guide the students to reflect on how understanding atmospheric phenomena can impact various areas of the job market, such as aviation, agriculture, and urban planning. Facilitate a discussion on how the knowledge gained can be applied in real situations and the importance of predicting extreme weather events to minimize damage.

Mini Challenge

Building an Anemometer: Measuring Wind Speed

Students will build a simple anemometer with recyclable materials to measure wind speed. The activity involves assembling the device, collecting data, and analyzing the results.

Instructions

1. Divide the students into groups of 4-5 people.
2. Distribute the necessary materials: plastic cups, straws, pushpins, pencils with erasers, adhesive tape, and a ruler.
3. Instruct the students to follow these steps to build the anemometer:
4. Make four evenly spaced holes on the side of one of the plastic cups.
5. Insert a straw into each hole and secure it with adhesive tape.
6. In the center of the straws, place a pushpin to secure them to the eraser of the pencil.
7. Ensure that the straws can rotate freely.
8. Mark one of the cups to identify the number of rotations.
9. Take the students to an open space and ask them to hold the anemometer against the wind.
10. Count how many rotations the marked cup makes in one minute.
11. Help the students calculate the wind speed based on the rotations.
12. Compare the results obtained by each group and discuss possible variations.

Objective: Develop practical skills in assembling and analyzing simple meteorological devices, promoting understanding of the physical principles behind measuring wind speed.

Duration: 30 - 35 minutes

Evaluation Exercises

1. Describe how the difference in temperature and pressure influences the formation of winds.
2. Explain the process of rain formation and the factors that can affect its intensity.
3. Relate the importance of understanding atmospheric circulation to the prediction of extreme weather events.
4. Research a recent extreme weather event and describe how weather forecasting helped minimize the damages caused.
