EQ: How are living thingsEQ: How are living things
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
Lesson 1- P. 266-275Lesson 1- P. 266-275
Classification is the grouping of similar
By identifying characteristics that living
things share, scientists can group
similarities, like the way that organisms
look, live, eat move, grow, change and

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
Grouping Living ThingsGrouping Living Things
Scientist classify living things into major groups called kingdoms. Members
of each group have certain characteristics.
•Made of many cells,
•Feed on other living or once living
•Made of many cells
•Make their own food
•Made of many cells
•Don’t make or eat food
•Single celled organisms
•Cells have no nucleus
•Some make food
•Most absorb food
•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
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
I can demonstrate how vertebrates and
invertebrates are classified into groups.
Vertebrates and InvertebratesVertebrates and Invertebrates
Vertebrates are animals with a backbone:
Examples: human, cat, dog, giraffe, snakes
Invertebrates are animal without a
Examples: sponges, jellyfish, anemones, and
More About VertebratesMore About Vertebrates
There 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
3. Reptiles-Scaly skin, most lay eggs i
4. Birds-Have feathers, most fly, not all
5. Mammals-Have hair and produce milk for
More about InvertebrateMore about Invertebrate
Invertebrates are the largest part of the
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.

How are plants sorted into groups?How are plants sorted into groups?
Nonvascular Plants: Plants that do 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 TissueTwo Types of Vascular Tissue
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
