Plant and Animal Needs for Grade 2

Plants and animals are living things. Even though they look very different, they all need certain things to survive. When children understand these needs, they can better explain why living things grow well in some places and struggle in others.

All Living Things Have Needs

A living thing is something that grows, changes, and needs energy. Plants, animals, and people are all living things. Living things cannot survive without the right conditions around them.

Scientists observe what happens when a plant or animal gets enough of what it needs and what happens when something important is missing.

📌

Example A classroom plant grows better when it gets sunlight and water.

What Plants Need

Plants need sunlight, water, air, and space to grow. Sunlight helps plants make food. Water helps them stay healthy. Air and space allow roots, stems, and leaves to keep growing.

If a plant does not get enough water or light, it may droop, turn yellow, or stop growing well.

📌

Example A bean plant near a sunny window often grows taller than one left in a dark corner.

💡

Tip Ask students to notice changes over time instead of expecting growth in one day.

What Animals Need

Animals need food, water, air, and shelter. Different animals get these needs in different ways. A bird may build a nest, while a rabbit may use a burrow.

Animals also need safe places to rest and raise their young. When food or shelter is hard to find, animals may move to a different place.

📌

Example A squirrel needs air to breathe, water to drink, food to eat, and a tree for shelter.

Needs Connect to Habitats

A habitat is the place where a living thing finds what it needs. A pond habitat gives frogs water, food, and shelter. A desert habitat gives cactus plants lots of sunlight and dry soil.

When children connect needs to habitats, they can explain why one place works well for one living thing but not for another.

📌

Example A fish can live in a pond habitat, but it would not survive in a dry desert.

📐 Standards Alignment

2-LS2-1 NGSS

Plan and conduct an investigation to determine if plants need sunlight and water to grow.

K-ESS3-1 NGSS

Use a model to represent the relationship between the needs of different plants or animals and the places they live.

2-LS4-1 NGSS

Make observations of plants and animals to compare the diversity of life in different habitats.

🔗 Glossary Connections

Living Thing A living thing is something alive, like a plant, animal, or person. Habitat A habitat is the place where a plant or animal lives and gets what it needs. Life Cycle A life cycle is the pattern of changes a plant or animal goes through from beginning to adult.

⚠️ Common Mistakes to Watch For

Thinking plants do not need air because they do not move around
Believing every animal needs the exact same kind of shelter
Forgetting that needs must be met over time, not just once

🌍

Real-World Connection Children see living things meeting their needs in gardens, parks, pet care routines, and classroom science investigations.

Fun Fact! Some desert plants can store water in their stems so they can survive for long stretches without rain.
