Living Things Grow What happens when you plant a seed? What happens to a baby kitten?

All living things grow Over time all living things change with age. All organisms use energy

Living Things Respond Respond means- react When a plant is in the shade it responds by bending towards the light What happens when a cat sees a dog?

Gases Animals need oxygen to survive Where do you find oxygen?

Answer Air and water

Question Who uses oxygen in the water?

Answer Clams, fish, and most sea animals

Plants What do plants need?

Answer Need oxygen and a gas called carbon dioxide Plants use energy from the sun to change carbon dioxide and water into food

Plants and Their Parts Lesson 2

What are plants? What are characteristics of plants? Make their own food Plants do not eat living things Most plants are green Most plants do not move Most plants do not stop growing. © 2009 abcteach.com

Plants What are some common structures found in most plants? Roots Stems leaves

Vocabulary Structures Parts of plants Help plants get what they need

What three structures do plants have? Roots Stems leaves

Critical thinking Most plants do not have structures for eating. What might be a reason for this? Plants do not eat food. They make their food from energy from the Sun.

What is a root? Plants take in water through their roots Roots also hold a structure in place Carrots and radishes have one thick root called a taproot.

Roots Not all plants have one big root (taproot) others have a web design Roots take in water, hold a root in place What else do plants absorb through their roots?

Roots Nutrients….. Substance that help living things grow and stay healthy Nutrients are part of the soil

Roots Can you think of roots we can eat? Carrots Radishes Sweet potatoes

Review Quiz Time How do roots help a plant meet its needs? What is a root? Name a root we can eat.

Question Review What is a nutrient? Where do we find nutrients?

Stems Stems are structures that hold up a plant Stems hold up leaves so that they get sunlight Stem carries water, nutrients and food throughout the plant

Question time What are the three functions of a stem? Name one root we can eat. What is the function of the root.

Stems Not all stems are the same Stems can be soft and green They can be hard and woody

Review How are plant roots different? How are roots alike? What is a stem?

Leaves Many shapes and sizes Leaf is where a plant makes its food Photosynthesis is the process in which plants make their own food

Photosynthesis Process in which plants make their own food Use energy from the Sun Change carbon dioxide and water into sugars Sugars are food for plants

Questions What job do leaves have? What is photosynthesis?

Answers Make food for the plant The process in which plants make food using energy from the sun

Questions What are some different types of leaves? What is the jobs of leaves? What enters through the tiny openings in the leaf?

Answers Narrow and pointy like a fern Broad and flat like the maple Shaped like a needle Make carbon dioxide Soak up the sunlight Make food

Leaves Chlorophyll gives leaves their color Plants give off oxygen People and animals need oxygen to live

Questions Where do plants get energy to make food? What does a plant to make food? What do plants give off during photosynthesis?

Animals Use senses to get information Wolf growls when sees , gears, smells another wolf near its young. Snake may lie in the sun when it is cold

Animals A cat will look for food when it is hungry Bees sting when they fear danger

Senses How do animals use their senses?

Animals Have structures Structures are parts…. Parts helps animals get what they need Legs, fins, wings, tails

Animals can move Animals move to find water and food Escape danger

How do animals move? Feet Legs Tails wings

Who has strong legs? Wolves Cheetahs House cats

Some animals have no legs Snails Snakes Birds

Questions What are some animals that move? Why do animals move? What structures do animals have to help them move?

How do animals get what they need? Water Food oxygen

Animals Have structures to help them get what they need!

Getting water and food Long tongues for water Birds have beaks Elephants have trunks

Food Structures helps animals get their food Lions scrape meat with their rough tongues Birds grab with worms with their beaks

Getting Oxygen Animals breathe to get oxygen Breathe with lungs Lungs are structures that take in oxygen

Fish Fish live in water They take in oxygen using gills Gills are structures that take in oxygen from the water

Breathing Some animals can breathe without lungs or gills. Worms Salamanders Through their skin

Questions What are gills? What are lungs? How do fish Breathe? How do humans breathe?

How do animals Stay Safe By Bad weather Other Animals

Protecting Find a place of shelter Shelter is a safe place Some animals have structures that help protect them

Protecting Some animals find shelter in the ground Groundhogs dig holes in the soil with their paws Lizards flatten their bellies and crawl under rocks

Protecting Some animals use trees Birds build nests Snail’s hard shell protects it

Questions Why do animals need shelter? What are some places where animals find shelter?

Answers Stay safe in their environment; protect themselves from bad weather;to protect from other animals that might eat them In holes in the ground; in caves; under rocks; in nests, plants, and trees

Questions What is shelter?

Answer A place where an animal can stay safe

How are an animal’s needs like a plant’s need? How are they different? Plant needs carbon dioxide, sunlight, and nutrients from the soil

Same Both plants and animals need food, water, space, and oxygen.

Different Animals must eat other organisms for energy

Question How might long legs help a bird that lives in a pond environment? Long legs might help a bird stand in water to look for food.

Question Animals use all the structures below to get oxygen except eyes

Question What helps animals survive in their environments? Animals survive in their environments by using their structures to get food, water, and oxygen.

Organisms Respond Reproduce Grow move

animals If all animals grow, reproduce, respond. How do you classify them?

Classify Animals Animals all look different. Think of tigers, ants, bluebirds, sharks. We can group them by their structures. Structures are………

Structures Structures are parts

Classifying One way we classify animals is by their backbone If they have one or if they do not have one

Vocabulary Vertebrate….animals that have a backbone Tigers, dogs, eagles, goldfish

Vocabulary Invertebrate.. Animals without a backbone. Insects Worms jellies

Invertebrates Live on land and water Sponges Worms and jellies Sea stars and urchins

Exoskeleton Antropods… insects..spiders..lobsters…beetles

Invertebrates Mollusks Clams Snails octopuses

Invertebrates Exoskeleton, thin, hard covering Exoskeleton is a structure that protects their body

Questions What kind of invertebrates are protected by an exoskeleton?
