Context

Life on Earth is extraordinarily diverse and complex, with millions of species and countless individuals interacting in infinite ways. Plants are an essential component of this biodiversity, playing a crucial role in ecosystem functioning and the lives of other organisms, including humans. We, as human beings, depend on plants for the air we breathe, the food we eat, and the materials we use.

Within biology, the study of plants is called botany. It is a rich and dynamic field that encompasses many subfields, such as plant physiology (the study of plant function), plant ecology (the study of plant interactions with the environment and other organisms), and plant taxonomy (the classification of plants).

Studying plants is an essential step in understanding life on Earth. Plants are the primary producers of the biosphere, performing photosynthesis to convert sunlight into chemical energy, which sustains virtually all life on Earth. Additionally, plants help regulate the climate, protect water quality, preserve biodiversity, sequester carbon, and provide habitat for wildlife.

The importance of plants for human life is immense. They are the basis of our food and provide a large part of our medicinal needs. Moreover, many of our cultural and economic activities are linked to the plant world. At the same time, many of the current global challenges, such as climate change, biodiversity loss, and food security, are closely linked to the plant kingdom.

Plants are undoubtedly a fascinating and important field of study. And this project will allow us to explore this incredible diversity in engaging and practical ways.

Practical Activity: Scientific Gardener Project

Project Objective

The practical activity aims to promote students' approach to the plant world in a playful and investigative way. For this purpose, students will be proposed to create and monitor an experimental garden, relating concepts of Botany, Ecology, and Biogeochemistry.

Project Description

Students, organized in groups of 3 to 5, will build an experimental garden with different types of plants and will monitor the development of these plants over a specified period.

They should identify, classify the chosen plants, investigate their growth requirements (light, water, soil, temperature), and create hypotheses. During the experiment, students should daily record observations on plant growth and environmental conditions.

In parallel, students will be proposed a theoretical research on the physiological processes involved (photosynthesis, respiration, transpiration, among others) that should be presented in the format of a scientific article.

Required Materials

• Plants chosen by students;
• Pots or small areas of soil for planting;
• Watering can;
• Temperature and humidity meter;
• Precision scale;
• Notebook for notes;
• Camera or cell phone with a camera.

Step by Step

1. Formation of groups and selection of plants for the garden.
2. Research on the characteristics and needs of the plants.
3. Assembly of the experimental garden.
4. Daily monitoring (temperature and humidity measurement, plant weight, visual changes record).
5. Photographic record of plant growth.
6. Theoretical research on plant physiological processes.
7. Preparation of the scientific article.

Students should dedicate a minimum of 12 hours of work, including garden setup, monitoring, and article writing.

Project Deliverables

At the end of the project, each group must deliver:

1. Field Diary: Notebook with daily garden records, containing notes on temperature, humidity, plant height, and observations on their development.

2. Photographic Record: Digital file containing photos of the garden from the beginning to the end of the experiment.

3. Scientific Article: Each group must deliver a written document in the format of a scientific article, divided into:

a) Introduction: where the work's theme will be contextualized, its relevance, real-world application, and project objectives.

b) Development: with the theory that underpins the project, a detailed description of the practical activity, applied methodology, and analysis of the results obtained.

c) Conclusion: explanation of the learnings obtained and the conclusions drawn about the project.

d) Bibliography: list of sources and resources used for the project.

The document writing should be done together by the group, distributing tasks among members to promote collaboration and teamwork.
