EQ: How are living things EQ: How are living things grouped?grouped?S5L1. Students will classify organisms into groups and relate how they determined the groups with how and why scientists use classification.

Demonstrate how animals are sorted into groups (vertebrate and invertebrate) and how vertebrates are sorted into groups (fish, amphibian, reptile, bird, and mammal).

Demonstrate how plants are sorted into groups.

I can explain why scientist classify living things.

Lesson 1- P. 266-275Lesson 1- P. 266-275ClassificationClassification

Classification is the grouping of similar things together.

By identifying characteristics that living things share, scientists can group similarities, like the way that organisms look, live, eat move, grow, change and reproduce.

Classification is the process of grouping things together. It is useful in studying how living things are alike and how they are different. Classification makes finding and sharing information and sharing information easier.

Grouping Living ThingsGrouping Living ThingsScientist classify living things into major groups called kingdoms.

Members of each group have certain characteristics.

Kingdoms

Animals: •Made of many cells, •Feed on other living or once living things

Plants:•Made of many cells•Make their own food

Fungi:•Made of many cells•Don’t make or eat food•Absorb food

Bacteria:•Single celled organisms•Cells have no nucleus•Some make food•Most absorb food

Protist:•Mostly single celled•Some make food•Others take in food

* Note: Sometimes bacteria is divided into two groups.

Smaller GroupsSmaller Groups Kingdoms are divided in to smaller groups. Each smaller group shares more and more of the

same characteristics.

SpeciesSpecies

Species is the smallest group. Species means a unique kind of organism. Species is an exact group of one kind of organism.

EQ: What are vertebrates and invertebrates?

I can demonstrate how vertebrates and invertebrates are classified into groups.

Vertebrates and Vertebrates and InvertebratesInvertebratesVertebrates are animals with a

backbone:Examples: human, cat, dog,

giraffe, snakes

Invertebrates are animal without a backbone.

Examples: sponges, jellyfish, anemones, and coral

More About VertebratesMore About VertebratesThere are five phyla of vertebrates.1.Fish – Absorb oxygen that is

dissolved in water (trout and shark)2.Amphibian-Begin life in water, Many

live on land but return to water to lay eggs (frogs and toads)

3.Reptiles-Scaly skin, most lay eggs i4.Birds-Have feathers, most fly, not all 5.Mammals-Have hair and produce

milk for their young

More about InvertebrateMore about InvertebrateInvertebrates are the largest part of

the animal kingdom.Invertebrate include: sponges

jellyfish, anemones and coral.Many echindoderm have spines and

body parts arranged in multiples of five. (ie. Starfish, sand dollars and sea urchins

Anthropods are the most common group. The have joined legs and bodies that have segments.

Structure and FunctionStructure and Function

Structure is the form of a body part.

Function is what a structure does.

For example, a wing is a structure and flight is its function.

Turn to your partner and share an example of structure and function.

not havetrue roots, but are anchored in the ground by small root-like structures. (mosses)

Vascular Plants: Plants that have tissue that supports and carries food and water. Vascular means “vessel” and the function of the vascular tissue to to transport water and nutrients. (roots, stems, and leaves)

Two Types of Vascular Two Types of Vascular TissueTissue

Xylem: carries water and nutrients from roots to other parts of a plant.

Phloem: carries food from leaves to the rest of the plant.

Name three examples of vascular plants.

Explain how vascular and nonvascular plants are different.

Seed Bearing PlantsSeed Bearing Plants

Gymnosperm- a plant produced by a naked seed (or a seed that is not protest by a fruit. It is only protected by a seed coat)

Angiosperm- a flowering plant, which has its seeds protected by a fruit
