Living and Nonliving Things for Kindergarten
Kindergarten students see living and nonliving things every day, but they often sort them by movement or size instead of by scientific patterns. Science helps children look more carefully. A puppy, a tree, and a flower are all living things even though they do not move in the same way. A rock, a toy car, and a chair are nonliving even though some can move when someone pushes them. This topic matters because it gives children one of their earliest ways to classify the world. Instead of guessing, they begin to use evidence. They ask whether something grows, needs water or food, and changes over time. Those questions help young learners build real science habits. The lesson also connects to empathy and observation. When children understand that plants and animals are living things with needs, they can better understand why habitats, care, and safety matter. That idea becomes important in later lessons about plants, animals, and environments.
Living Things Are Alive
A living thing is something that is alive. Living things grow and change over time. They also need things such as water, food, air, or sunlight to live. Plants, animals, and people are all living things.
This idea is useful because children sometimes think only moving animals are alive. Science helps them notice that plants are alive too, even though they stay rooted in one place. A seed can grow into a plant, and a baby animal can grow into an adult. Growth is one clue that something is living.
Students do not need a long definition at first. They need repeated examples and simple evidence they can talk about.
Nonliving Things Are Not Alive
A nonliving thing is not alive. It does not grow because of its own body, and it does not need food, water, or air to survive. A rock may get bigger if dirt piles on it, but that is not the same as growing like a plant or animal. A toy may move, but only because a person, battery, or motor makes it move.
This is an important distinction for young children. Movement alone does not prove that something is alive. A rolling ball is not living. A tree is living even when it stands still. Students need to compare many examples to build this understanding.
Science classification becomes stronger when students learn to explain why something belongs in a group.
Living Things Have Needs
Living things need certain things to survive. Animals need food, water, air, and shelter. Plants need water, air, sunlight, and space to grow. When students talk about needs, they begin to see why living things are different from toys, rocks, and classroom tools.
This section helps children move beyond labels. A living thing is not just a name for a plant or animal. It is something with real needs. If those needs are missing, the living thing may not stay healthy or alive.
That connection makes later science topics easier because students already understand why habitats and care matter.
Observation Helps Us Sort Things
Observation means using your senses carefully to notice details. Students can observe whether something grows, needs care, changes over time, or is made by people. Good observations help them sort objects into living and nonliving groups.
Kindergarten science grows when children use evidence instead of guessing. They can look at a leaf, a shell, a pet, a stuffed animal, and a rock, then explain what they notice. Even when an object is tricky, observation gives them a stronger way to decide.
This is also a good time to remind children that pictures and classroom objects can stand in for things they cannot bring into the room. Science reasoning still works when they explain what they know from observation and experience.
Some Objects Can Be Tricky
Young learners often find some examples confusing. A stick came from a tree, but the stick on the ground is no longer living in the same way the tree is. A toy dog looks like an animal, but it is nonliving because it does not eat, grow, or breathe. A seed may look small and quiet, but it is living because it can grow under the right conditions.
Talking through tricky examples is valuable because it shows students that science is about careful thinking. They learn to ask questions and use evidence instead of making a quick guess.
This section also teaches humility in science. If a student is unsure, they can observe more and explain their reasoning. That is good scientific behavior.

Use observations to describe patterns of what plants and animals (including humans) need to survive.
Use a model to represent the relationship between the needs of different plants or animals and the places they live.

- Thinking anything that moves must be living
- Believing plants are nonliving because they stay in one place
- Assuming something is living only because it looks like an animal or plant
