organisms into kingdoms, then smaller groups by traits.

Lesson 1: How are Living Things Grouped? P68- 69

Classification – Purpose- To be able to find things easily

Classification is grouping similar things together.

Five Kingdoms A kingdom is the

largest group into which things can be classified.

Kingdoms Animal Plant Fungi Protists Bacteria (Monera)

Animal Kingdom - Many-celled Feed on living or once living things Examples – Humans, dogs, tigers, birds Plant Kingdom - Many-celled Make their own food Examples: Trees, flowers, grasses, ferns,

mosses Fungi Kingdom -Most many-celled Absorb food from other living things or

dead things such as logs Examples: Mushrooms, yeasts, molds

Protists Kingdom - Most one-celled Make their own food or feed on once

living things Examples: Algae, amoebas, diatoms• Bacteria Kingdom (Monerans) – • One –celled• No nucleus• Some make their own food• Some feed on living or once living things

Kingdom ProjectThis project is worth 100 points. Each student is to create a book about the five kingdoms. Each project should include the names, important characteristics, and examples of each kingdom. The student name and a title for the project must also be included. Students may use computers, magazines, or their own drawings. Neatness and creativity will be graded.

Forming Smaller Groups

Vascular PlantsHave tubesExamples:

Trees Ferns Any plant with flowers or cones

Vascular tissue – transport or conduct materials around plant

Xylem – water and minerals up

phloem – food down

Non Vascular Plants Do not have tubes. Water must soak into plants and pass

slowly from cell to cell. Usually live in damp places. Usually don’t grow tall.

Build Model Backbone page 75 Do Questions ate the bottom.

Invertebrates v. Vertebrates

Did you Know?About 97% of all living animals

are invertebrates!!

Did you Know?About 45,000 living species

constitute the group vertebrates!!

Vertebrates

Amphibians Reptiles Birds Fish Mammals

MammalsThey are warm

blooded.Feed their young

milk.They have hair.

Reptiles

Red-bellied Black Snake - it’s poisonous!

Saltwater Crocodile - largest living reptile!

They are cold blooded. Have dry, scaly skin. Usually creep or swim, similar to

amphibians. Lay large shelled eggs, or in some

cases give birth to live young.

Frilled Lizard - lives in Northern

Australia

Amphibians Have moist skin and no

scales. They are cold blooded. Tend to be aquatic and are

limited to moist surroundings. Consist of toads and

salamanders

Cane Toad - found in Queensland, Australia

Fish They are cold blooded. Found in both fresh and

salt water. Breath through gills. Includes: jawless fish,

cartilaginous fish like sharks and rays, and bony fish.

Clown Fish - found around the Great Barrier Reef

Great White Shark (White Pointer) - protected species in

Australia

Birds Most have feathers. Most species are capable of

flying, some are sedentary, and some are flightless.

Lay shelled eggs, and care for young in a nest.

Fairy Penguins - smallest penguin species in the world

Emu - flightless bird, native to

Australia

Kookaburra - largest king fisher

Invertebrates

Insects Arachnids Worms Mollusks (without shells)

Worms Includes: earthworms,

leeches, and tapeworms. Bodies are divided into 100 or

more body segments. The earthworm has no lungs;

it takes in oxygen through its moist body. If an earthworm dries out, it will suffocate.Helobdella papillornata - a

native Australian leech

MollusksThey have soft,

segmented bodies. Some have shells.

Includes: octopus, jellyfish, slugs, snails, clams, and oysters.

The octopus has the most complex brain of any invertebrate.

Blue-Ringed Octopus - only lethal octopus whose blue rings

glow when it’s angry

EchinodermsSea stars, sand

dollars, and sea urchins.

Most have body parts in multiples of five.

Arthropods Invertebrates with

legs that have several joints

Bodies have two or more parts

Often have an outer covering that protects them

Crustaceans, insects, and spiders are arthropods

CrustaceansMany have clawsSome have

antennaeExamples: crabs,

lobster, and shrimp

Insects There are over 1 million

different known species of insects.

They have hard jointed exoskeletons.

The adult body have three parts: the head, thorax, and abdomen.Ulysses Butterfly - protected species

in Queensland, Australia

Arachnids They have 8 legs. Includes: spiders,

scorpions, ticks, and mites.

Most species of scorpions and spiders are not dangerous to humans.

Funnel-Web Spider - found in Sydney, very poisonous

Red Back Spider - when confronted will

feign death and curl up -

only bites when trapped against skin

Structure and FunctionStructure is the

form of the body part.

Function is what the structure does.

The function of the legs are the same, but the structure is different.
