Unit A, Ch.1, Lesson 1(How Living Things Are Alike)Vocabulary:OrganismReproductionEnvironmentRespondCellObjective:All living things have common features.What are the features of living things?

= a living thingHow can you tell an organism from a nonliving thing?there are certain ways to tell a living from non living thing.

5Organism

Unit A, Ch.1, Lesson 1(How Living Things Are Alike)Vocabulary:OrganismReproductionEnvironmentRespondCellObjective:All living things have common features.Organisms also change as they grow.The way a living thing changes during its life is called

As an oak sapling grows, the branches and trunk become thicker and stronger.The oak tree also changes its color and shape as it develop.8development

Unit A, Ch.1, Lesson 1(How Living Things Are Alike)Vocabulary:OrganismReproductionEnvironmentRespondCellObjective:All living things have common features. Living Things Reproduce

The way organisms make more of their own kind.Plants grow from seeds.Chicks hatch from eggs.Some animals like puppies are born live.# Some new living things (offspring) are not exact copies of their parents, they have characteristics of both parents.#the color of flowers depend on the color of its parents.

10Reproduction

Unit A, Ch.1, Lesson 1(How Living Things Are Alike)Vocabulary:OrganismReproductionEnvironmentRespondCellObjective:All living things have common features.How do organisms react to change?

is made up of everything that surrounds an organism.It includes: air water soil other organisms11Environment

Unit A, Ch.1, Lesson 1(How Living Things Are Alike)Vocabulary:OrganismReproductionEnvironmentRespondCellObjective:All living things have common features. Living Things Respond

When the environment changesAn organism respond = react to that change.123

Unit A, Ch.1, Lesson 1(How Living Things Are Alike)Vocabulary:OrganismReproductionEnvironmentRespondCellObjective:All living things have common features.# Both plants and insects respond to light:Plants bend toward light.Insects fly toward itThe leaves on some trees respond to change in season,In autumn they turn colors then fall off the branches.13

Unit A, Ch.1, Lesson 1(How Living Things Are Alike)Vocabulary:OrganismReproductionEnvironmentRespondCellObjective:All living things have common features.Animals also respond to change in seasons:Bears eat a lot of food as winter nears, then sleep or rest through the winter in a cave.

You respond to environment in different ways:You may shiver if you are cold

Unit A, Ch.1, Lesson 1(How Living Things Are Alike)Vocabulary:OrganismReproductionEnvironmentRespondCellObjective:All living things have common features. How do living things communicate?

is to share information.To communicate organisms: send collect to signals respond How do organisms communicate?15communicate4

Unit A, Ch.1, Lesson 1(How Living Things Are Alike)Vocabulary:OrganismReproductionEnvironmentRespondCellObjective:All living things have common features.#Fireflies flash lights to attract mates.#Some birds sing to mark the area where they live.#male red-winged blackbird sing it says to other males stay out of my territory#the cuttlefish changes skin color and texture, to alert other animals that it is looking for food.16

Unit A, Ch.1, Lesson 1(How Living Things Are Alike)Vocabulary:OrganismReproductionEnvironmentRespondCellObjective:All living things have common features.To receive communications, living things use their senses ofSightSmellHearingTouchCan all receive information. 17

Unit A, Ch.1, Lesson 1(How Living Things Are Alike)Vocabulary:OrganismReproductionEnvironmentRespondCellObjective:1-All organisms are made of cells2-compare between plant and animal cell.What are the smaller parts of living things?More than 300 years ago, scientist Robert Hooke looked at a thin piece of cork through a microscope, he saw that the cork made of tiny boxlike shapes that are called cells.

Unit A, Ch.1, Lesson 1(How Living Things Are Alike)Vocabulary:OrganismReproductionEnvironmentRespondCellObjective:1-All organisms are made of cells2-compare between plant and animal cell.

Are the basic building blocks of life.All living things are made of cells.Your own body is made of billions of cells.Plant and animal cells have many of the same parts, and also some differences.
