Introduction — A Nature Walk
It is a pleasant morning after yesterday's refreshing rain. Dr Raghu, a scientist at a nearby Research Laboratory, and Maniram chacha, an elderly person from the community who is brilliant at identifying plants and animals, have been invited by Madam Sulekha, the science teacher, to take the students on a nature walk.
As they walk through the park, the students begin exploring the plants and animals around them. Dr Raghu advises them to notice the variety of smells, to observe all living creatures respectfully without disturbing them. Maniram chacha tells the students to not only observe different plants and animals but also to carefully listen to different sounds.
🐦 Did you notice? Each bird has its own unique chirp — this is an example of diversity in nature! Maniram chacha can even mimic the calls of different birds.
The students come across a variety of plants — grasses, bushes, and large trees. They observe birds sitting on branches, butterflies moving from flower to flower, and monkeys jumping from tree to tree. They record all their observations in their notebooks.
2.1 Diversity in Plants and Animals Around Us
🧪 Activity 2.1 — Let Us Explore and Record
L3 Apply
🤔 Predict first: If you go on a nature walk to a park or nearby forest, how many different types of plants do you think you will find — fewer than 5 or more than 10?
- Plan a nature walk with your teacher to a park or nearby forest.
- While on the walk, observe different plants, insects, birds, and other animals. Note weather conditions too.
- You can collect different types of fallen leaves or flowers and create a scrapbook.
- Take care of the plants and animals in nature. Do not pluck leaves and flowers.
- Record your observations in Tables 2.1 and 2.2.
What to look for in plants: Local name, type of stem (soft/hard, thin/thick), shape and arrangement of leaves, whether it has flowers, and any other interesting features like thorns, smell, or colour.
What to look for in animals: Local name, where it lives (tree, soil, water), what it eats, how it moves, and any interesting features like colour, size, or sound.

Examples of Different Plant Features L4 Analyse
Table 2.1: Observations of Different Plants Around Us
| S. No. | Local Name | Stem | Leaves (shape / arrangement) | Flowers | Any Other Observations |
|---|---|---|---|---|---|
| 1. | Common Grass | Soft and thin | A single leaf grows alternately from different points on the stem | — | Green leaves |
| 2. | Tulsi | Hard and thin | Arrangement: a pair of leaves in the opposite directions | Pinkish purple | Aromatic leaves |
| 3. | Hibiscus | Hard | Broad, toothed edges | Large, red | Woody stem |
| 4. | Neem | Hard and thick | Compound leaves with small leaflets | Small, white | Leaves with smooth surface, bitter taste |
| 5. | Your observation | — | — | — | — |
What similarities and differences did you find among the plants that you observed? You must have noticed that plants have a variety of features — tall/short, hard/soft stem, different shapes of leaves and their arrangement, and flowers varying in colour, shape, and scent.
Table 2.2: Observations of Different Animals Around Us
| S. No. | Name of Animal | Place Where It Lives | Food It Eats | How It Moves | Any Other Observations |
|---|---|---|---|---|---|
| 1. | Crow | Tree | Insects | Fly and walk | Twig-like nest on trees |
| 2. | Ant | Nest in soil and burrow | Leaves, seeds and insects | Walk | Has six legs |
| 3. | Cow | Shed | Grasses, leaves | Walk | Gives milk |
| 4. | Your observation | — | — | — | — |
You would have observed that some animals live on land while some others live on trees. Birds live on trees. Fish live in water and some animals like frogs live on land as well as in water. Animals consume a diverse range of foods and exhibit a variety of movements.
🧪 Activity 2.2 — Let Us Appreciate
L2 Understand
🤔 Think first: Close your eyes for 30 seconds. Think of one plant and one animal that you have closely observed and appreciated very much.
- Draw the plant and animal you thought of on a piece of paper.
- How many different plants and animals did the entire class draw on the blackboard?
- Do you think there may be many more varieties than those drawn?
What you'll find: Even in a single classroom, students will draw a wide variety of different plants and animals — showing that nature has tremendous diversity even in the area immediately around us. This variety of plants and animals found in a particular region contributes to the biodiversity of that region.
📖 Biodiversity refers to the variety of plants and animals found in a particular region. Each member of the biodiversity of a region has a different role to play. For example, trees provide food and shelter to birds and other animals; animals help in spreading seeds. Plants and animals are dependent on each other.
2.2 How to Group Plants and Animals?
How would you arrange your books and notebooks in groups? Would arranging them in groups help you better organise your school bag? Now, let us look at the world around us. We are surrounded by a variety of plants and animals with different features. We can group them based on similarities and differences among them.
🧪 Activity 2.3 — Let Us Group
L4 Analyse
🤔 Think first: If you had to sort 20 different plants into groups, what feature would YOU choose to group them by?
- Collect pictures of various other plants and animals. Cut their pictures from old magazines, newspapers, or print them. Paste each picture on a different card.
- Divide your class into groups of 5–6 students each.
- Pool the cards prepared by the students in your group.
- Observe various features of plants and animals shown on the cards.
- Recall the features of plants and animals you listed in Tables 2.1 and 2.2.
- Group them on the basis of common features.
- Share and discuss the basis of grouping you have made with other groups.
Interesting finding: You will be surprised to see that the basis used by different groups may vary! Some students may have chosen the height of plants as the basis for grouping, while others might have chosen the presence or absence of flowers. This is perfectly fine — there are many valid ways to group living things. Scientists call this process classification.
🔍 Interactive: Possible Criteria for Grouping L4 Analyse
💡 Why do we group? Grouping makes it easier to understand and study the enormous variety of plants and animals on Earth. Scientists call the method of arranging things into groups based on their common features as classification. You will learn more about the importance of grouping in the chapter 'Materials Around Us'.
📋 Competency-Based Questions
During a nature walk in their school garden, Priya observed 8 different types of plants and 5 different animals. She recorded their features in a notebook. Her teacher asked the class to group the organisms based on their observations.
Q1. L2 Understand What is the variety of plants and animals found in a particular region called?
Answer: B. The variety of plants and animals found in a particular region is called biodiversity. Each member contributes a unique role to the ecosystem.
Q2. L1 Remember Fill in the blank: The method of arranging things into groups based on common features is called __________.
Answer: classification (or grouping)
Q3. L4 Analyse Priya grouped a rose plant and a mango tree together because both have flowers. Her friend grouped them differently — putting the rose in one group (small plants) and the mango tree in another (tall plants). Who is correct and why? (Short Answer — 2 marks)
Answer: Both Priya and her friend are correct. The grouping depends on the criteria (basis) chosen. If the criterion is "presence of flowers", both belong together. If the criterion is "height", they go in different groups. In science, there are often multiple valid ways to classify organisms depending on the features chosen.
Q4. L5 Evaluate True or False: "Plants and animals are independent of each other and do not affect each other's survival." Justify your answer. (3 marks)
Answer: False. Plants and animals are highly interdependent. Trees provide food (fruits, leaves) and shelter to birds and animals. Animals help plants by spreading seeds to new areas after eating fruits. Bees and butterflies pollinate flowers, helping plants reproduce. Without this interdependence, neither could survive as they do today.
Q5. L6 Create HOT: Design a simple classification chart to group 6 animals of your choice into at least 2 groups. State the basis (criterion) you used for grouping. (3 marks)
Hint: Choose 6 animals (e.g., fish, crow, snake, frog, cow, butterfly). Think of one feature that divides them into groups — for example: "How do they move?" (fly / walk / swim / crawl). Draw a simple chart showing the groups.
🔗 Assertion–Reason Questions
Assertion (A): Different groups of students may group the same set of plants and animals differently.
Reason (R): Grouping depends on the criteria or features chosen, and different people may choose different criteria.
Answer: A. Both statements are true. Different groups may use different criteria (height, stem type, eating habits, etc.) which leads to different groupings. The Reason correctly explains why the Assertion is true.
Assertion (A): Each bird has its own unique chirp.
Reason (R): This is an example of diversity in nature.
Answer: A. Both are true. Each bird species has a distinct call/chirp, and this variation in calls is indeed an example of diversity (variation) found in nature. The Reason correctly explains the Assertion.
Assertion (A): Frogs can live both on land and in water.
Reason (R): All animals can live in only one type of environment.
Answer: C. Assertion is true — frogs are amphibians that can live both on land and in water. Reason is false — many animals (frogs, turtles, crocodiles) can live in more than one environment.
