Lesson 1 Living Things and Their Needs Lesson 2 Plants and Their Parts Lesson 3 Animals and Their Parts Lesson 4 Classifying Animals How do living things get what they need to live and grow? organism respond reproduce environment cell What are living things? Living things grow, respond to the world around them, and reproduce. What do living things need? Living things need food, water, and space. Many also need gases found in air or water. What are living things made of? Living things are made up of cells. Main Idea How can you tell the difference between a living and a nonliving thing? Living things have needs, grow, respond, and reproduce. Living things are made up of cells. Nonliving things do not have needs and do not grow, reproduce, or respond. Vocabulary Living things ___________ , or react, to the world around them. Cells ___________ are the building blocks of life. An ___________ is all the living and nonliving things that surround an organism. Living things are called ___________. To ___________ means to make more of one’s own kind. cells environment organisms reproduce respond Main Idea and Details What do living things need to survive? food Living things have needs to survive. water gases in air or water space End of Lesson structure root nutrient stem leaf photosynthesis What are plants? Most plants have roots, stems, and leaves. They use energy from the sun to make their own food. How do roots and stems help plants? These are structures which hold the plant in place and help it take in nutrients. Why are leaves important? Leaves take in the carbon dioxide and sunlight that plants need for photosynthesis. Leaves also give off oxygen and make food for the plant. How can you classify plants? You can classify plants by their structures (roots, stems, leaves) or by whether they are flowering or non-flowering. Main Idea What three structures do most plants have? Roots, stems, leaves Vocabulary Plants make food through a process called ______________. ______________ are substances that help Nutrients living things grow and stay healthy. Many plants have the same basic ______________, or parts. nutrients photosynthesis structures Vocabulary Roots are structures that take _________ in water and hold a plant in place. A _________ is the structure where a plant makes food. A _________ is a structure that holds up a plant. leaf roots stem Summarize How do a plant’s parts help it survive? Roots take in water and nutrients and keep a plant in place. Stems hold a plant upright so its leaves can get sunlight and they transport materials throughout the plant. Leaves take in carbon dioxide and energy from sunlight. Leaves are where photosynthesis takes place. Parts of a Plant End of Lesson lung gills shelter What are animals? Animals are living things that can usually move and respond to their environment in a variety of ways. They get their energy and nutrients by eating other organisms. How do animals get what they need? Animals have structures that help them get what they need for survival. How do animals stay safe? Some animals have structures to help them stay safe and the others find shelter. Main Idea How are animals alike? All animals move, respond to their environment in noticeable ways, eat other organisms for energy, and have structures that help them meet their needs. Vocabulary Gills ___________ are structures that take in oxygen from the water. Some animals stay safe by finding a safe place, or ___________. Lungs ___________ are structures that take in oxygen from the air. gill s lungs shelter Compare and Contrast Plants need carbon dioxide, sunlight, and nutrients from the soil. Both plants and animals need food, water, space, and oxygen. Animals must eat other organisms for energy. End of Lesson vertebrate invertebrate exoskeleton bird reptile amphibian fish mammal How can you classify animals? Animals can be classified based on their structures. What are some invertebrates? What are some vertebrates? What are mammals? Mammals are vertebrates with hair or fur, and are born alive. You are a mammal too! Main Idea Name five groups of vertebrates. Fish, birds, amphibians, reptiles, mammals Vocabulary Many vertebrates have a thing, hard covering, called an ______________. Reptiles ______________ are vertebrates with scaly skin. Mammals ______________are vertebrates with hair or fur. Animals without backbones are called ______________. exoskeleton invertebrates mammals reptiles Vocabulary Animals with backbones are called ____________. Animals that spend part of their lives in water and part on land are called ____________. Fish ____________ are vertebrates that spend their whole lives in water. A ____________ is a kind of animal with a beak, feathers, two wings, and two legs. bird fish vertebrates amphibians Classify Mammal A zebra has hair and gives birth to live young. Mammal A zebra does not have scales or feathers like other groups of vertebrates. End of Lesson
