Midterm Science Review 202 Chapter 1: Plants Lesson 1: What Living Things Need By Teacher Olivia

Vocabulary 1. ________: Bits of rock and soil that help plants and animals grow. * Roots take in ____ from soil to help a plant make food. 2. ________: A gas found in the air we breathe. * When plants make food, they give off ______ into the air. * People and animals need to breathe in _______ to live.

What do living things need? All living things grow and change. Animals Plants space (to move) space (observe how they grow) breathe air air drink water water eat food food (minerals) shelter (make their own food)

How do plants make food? Things that plants need to make their own food are: 1) sunlight 2) air 3) water 4) minerals 3 parts of a plant to help make food 1. Leaves: take in air and use sunlight to make food 2. Stem: 1) holds up the plant. 2) It allows water and food to travel through the plant. 3. Roots: 1) hold the plant in the soil. 2) take in water and minerals. 3) store food for the plant. * Roots always grow down *

Midterm Review Plants Lesson 2 Plants Make New Plants

Vocabulary flower : part of a plant that makes seeds and fruit. seed : part of a plant that can grow into a new plant. pollen : a sticky power inside the flower that helps make seeds. life cycle : shows how a living thing grow, lives, makes more of its own kind, and dies. seedling : a young plant.

Seeds Seeds are made inside a flower, but sometimes a flower will grow seeds inside of a fruit. The fruit protects the seeds inside. All seeds have seed coats or fruit to protect them as they grow. Sees have food inside them to help the new plant grow. There are many different shapes and sizes of seeds.

Parts of Seeds 1. Seed coat: a) thin covering b) protects the seed C) protect the seed from drying out 2. Shell: hard shells 3. Tiny plant: will grow bigger 4. Body part: store food and give food to the tiny plant

How do seeds travel? 1) Wind 2) Water 3) Animals: bugs and birds 3 ways of how seeds can travel to different plants or places.

How do seeds grow? The plant life cycle begins with a seed. Seed  (sprout) seedling (young plant)  Adult plant Most plants follow the same life cycle as their parent plants. Different kinds of plants have different life cycles. What do seeds need to grow? 1) a warm place 2) light 3) water 4) food

Midterm Review Plants: Lesson 3 How Plants Are Alike and Different

Vocabulary Trait: The way a living thing (plants or animals) look or act. eg. acorn  oak tree ; sunflower seed  sunflower * Young plants (offspring) and their parent plants might look different but will have the same shape of 1) flowers 2) petals 3) leaves

How do plants survive in different places? Why do plants change? - to fit their environment (the place where they live). - to stay safe from animals - to stay safe from the weather eg. Joshua desert (very dry place)  have few or no leaves.  store water in thick stems. eg. banana rainforest (very wet places)  large leaves (help to get sunlight)

Midterm Science Review Chapter 2: Animals Lesson 1: Animal Groups

Animal Groups Scientists Classify animals by putting them into 2 main groups. Backbones < No Backbones (vertebrate) (invertebrate) mammals reptile amphibians insect birds fish

Animals with Backbones Mammals: 1) hair or fur e.g. lions 2) feeds milk to its young 3) breathe through lungs Amphibians: 1) moist skin e.g. frogs 2) live both in water & on land Birds: 1) feathers (only animal with feathers) 2) two wings and a beak * Not all birds can fly, such a chicken

Animals with backbones Fish: 1) live in water 2) gills to breathe 3) fins to swim Reptiles: 1) scaly skin e.g. lizard 2) cold-blooded

Animals without backbones Insects: 1) 6 legs 2) 3 body parts 3) antennae: help them feel, taste & smell 4) hard outer shell: keep safe

Midterm Review Animals: Lesson 2 Animals Grow and Change

Vocabulary Life Cycle: tells how an animal starts life, grows to be an adult, has young, and dies. Chicken Life Cycle Egg – chicks (can feed themselves) – adult chicken * Male chicken: rooster ; female chicken: hen Butterfly Life Cycle Egg – larva – pupa – young butterfly – adult butterfly (caterpillar)

vocabulary Larva: the stage after an egg hatches A caterpillar is the larva stage of the butterfly. Pupa: When a caterpillar is ready to change, it stops moving. Its skin becomes a hard shell.

How an animal life begins? Eggs Live babies amphibian mammals insects reptiles birds fish Animals born out of an egg can survive on their own. They can see, walk, and feed themselves after they hatch. Animals born as live babies need parents to feed and care for them.

Meet Nancy Simmons She is a scientist who studies bats. She learn about what bats eat & where they live. Bats give birth to 1 baby at a time. Baby bat is called “pup” (small & pink with no hair) The pup gets milk from its mother and grow bigger.

Midterm Review Animals: Lesson 3 Staying Alive

Vocabulary Adaptation: is a body part or a way an animal acts that help it stay alive. e.g. Giraffes have long necks (why?) Camouflage - is a way that animals blend into their surroundings. - Keeps animals from being seen by their enemies. - 1) color & 2) shape of an animal helps it hide. * Can you find the chameleon in the second picture? Why do soldiers wear cloth like that in the third picture. * Ptarmigan feathers change color in summer (brown), fall (turn white) and in winter (white to blend with the snow).

How do animals stay safe? Ways that animals can stay safe/staying alive: 1. Stay in large groups. (fish) 2. Migrate: leave their home in winter to be in a warm place & to find food (birds) 3. Hibernate: Sleep during the cold winter (bear) 4. Hard shell: body parts to keep them safe. (turtle) 5. Bad smell: protect them from other animals. (skunk) 6. Use their colors or shapes to help hide. (leopard)
