- The EVS textbook for Class 4 suggests several practical experiments that can be conducted to enhance students' understanding of environmental concepts. These experiments are designed to be hands-on and interactive, allowing students to actively participate in the learning process. Some of the practical experiments suggested in the textbook include:
- Growing plants from seeds: Students can learn about the process of seed germination and plant growth by conducting an experiment where they plant seeds and observe their growth over a period of time.
- Testing soil composition: Students can collect soil samples from different locations and perform tests to analyze their composition. This experiment helps students understand the importance of soil fertility and its impact on plant growth.
- Water filtration: Students can create their own water filtration system using materials such as sand, gravel, and charcoal. This experiment helps students understand the process of water purification and the importance of clean drinking water.


- The EVS textbook also suggests various field trips that can be organized to provide students with real-world experiences related to environmental studies. These field trips aim to broaden students' perspectives and give them a firsthand understanding of different environmental concepts. Some of the field trips suggested in the textbook include:
- Visit to a local park or garden: Students can visit a nearby park or garden to observe different types of plants, trees, and flowers. They can learn about the importance of green spaces and the role of plants in maintaining a healthy environment.
- Trip to a recycling facility: Students can visit a recycling facility to understand the process of waste management and recycling. They can learn about the importance of reducing, reusing, and recycling waste to minimize environmental impact.
- Nature walk or trek: Students can go on a nature walk or trek to explore their natural surroundings. They can observe different species of plants and animals, learn about biodiversity, and understand the importance of conservation.

Overall, the EVS textbook for Class 4 not only provides theoretical knowledge but also encourages practical learning through experiments and field trips. These hands-on experiences help students develop a deeper understanding of environmental concepts and foster a sense of responsibility towards the environment.
