This Grade 2 EVS worksheet helps students understand growth by comparing the life stages of a lady and a tree.

Problem Analysis:

The worksheet is designed to help students understand the concept of growth in living things. It compares the growth stages of a lady (human) and a tree, and then asks questions about their growth patterns and characteristics. Additionally, it explores how a crow performs basic life functions.

Solution:

#### Part 1: Comparing Growth Stages
The images show two sets of growth stages:
1. Lady (Human): Baby → Toddler → Adult
2. Tree: Seedling → Sapling → Mature Tree

#### Questions and Answers:

1. Do you notice an increase in size? (Yes / No)
- Lady: Yes
- Tree: Yes

Explanation: Both humans and trees grow larger as they mature. The baby grows into a toddler and then into an adult, and the seedling grows into a sapling and then into a mature tree.

2. Have they developed new parts as they grow bigger? (Yes / No)
- Lady: Yes
- Tree: Yes

Explanation: As humans grow, they develop new body parts and features (e.g., teeth, hair, limbs). Similarly, trees develop new branches, leaves, and roots as they grow taller and wider.

3. Will they continue to grow further? (Yes / No)
- Lady: Yes (to a certain extent)
- Tree: Yes

Explanation: Humans continue to grow until they reach adulthood, after which their growth slows down but may still occur in terms of height and muscle mass. Trees, on the other hand, continue to grow throughout their lives, adding more height and girth each year.

4. Who will live for a greater number of years?
- Lady: Humans typically live for around 70–80 years.
- Tree: Trees can live for hundreds or even thousands of years, depending on the species.

Explanation: While humans have a relatively short lifespan compared to many trees, trees can live much longer. For example, some oak trees can live for over 200 years, and bristlecone pines can live for thousands of years.

#### Part 2: How a Crow Does All This
The worksheet asks how a crow performs the basic life functions of breathing, moving, eating, growing, feeling, and reproducing.

1. Breathe:
- Crows breathe using lungs, just like humans. They take in oxygen from the air and release carbon dioxide.

2. Move:
- Crows move by flying using their wings or walking on their legs. They use their strong feet and claws to grip surfaces and perch on branches.

3. Eat:
- Crows eat a variety of foods, including insects, small animals, seeds, fruits, and carrion (dead animals). They use their beaks to pick up food and swallow it.

4. Grows:
- Crows grow from eggs into chicks and then into adult birds. They develop feathers, grow stronger muscles, and reach full size over several months.

5. Feel:
- Crows have sensory organs that allow them to feel their environment. They have sensitive beaks to detect food, eyes for vision, ears for hearing, and nerves in their skin to sense touch.

6. Reproduce:
- Crows reproduce by laying eggs. Mated pairs build nests together, lay eggs, and take turns incubating them. After hatching, both parents feed and care for the chicks until they are ready to leave the nest.

Final Answer:

1. Increase in size?
- Lady: Yes
- Tree: Yes

2. Developed new parts?
- Lady: Yes
- Tree: Yes

3. Continue to grow further?
- Lady: Yes (to a certain extent)
- Tree: Yes

4. Who will live for a greater number of years?
- Lady: Humans (~70–80 years)
- Tree: Trees (hundreds or thousands of years)

5. How a crow does all this:
- Breathe: Uses lungs to inhale oxygen and exhale carbon dioxide.
- Move: Flies with wings and walks with legs.
- Eat: Picks up food with its beak and swallows it.
- Grows: Develops from an egg into a chick and then into an adult bird.
- Feel: Uses sensory organs like eyes, ears, beak, and skin.
- Reproduce: Lays eggs in a nest, which hatch into chicks.
