Learning outcomes By the end of today you will:  Bronze: List (L3)  Silver: Describe (L4)  Gold: Explain (L5) Invertebrates

 Can you remember what a vertebrate is?  Can you list a few examples. Extension  What do you think an invertebrate is?

We can classify animals into two main groups: vertebratesinvertebrates Have a backbone Do not have a backbone

We are going to use the x-ray machine to see if some animals are vertebrates or invertebrates Vertebrates are animals that have: A BACKBONE NO BACKBONE

Our first animal is a cat. Do you think a cat is a vertebrate? Click on the cat to x-ray it!

What about this fish? Do you think a fish is a vertebrate? Click on the fish to x-ray it!

What about this snail? Do you think a snail is a vertebrate? Click on the snail to x-ray it!

What about this dinosaur? Do you think dinosaurs were vertebrates? Click on the dinosaur to x- ray it!

What about this worm? Do you think a worm is a vertebrate? Click on the worm to x-ray it!

What about this frog? Do you think a frog is a vertebrate? Click on the frog to x-ray it!

What about this person? Do you think a human is a vertebrate? Click on the person to x-ray them!

Yes, a cat has a backbone, so it is a vertebrate Click here to carry on

We can put vertebrates into 5 other groups: mammalsfishbirds reptilesamphibians

Mammals are vertebrates They have a backbone They have lungs They are warm blooded and have fur or hair on their bodies They make milk to feed their babies They give birth to live babies. e.g. humans, monkeys, zebras, dogs, mice, horses, cats, elephants, whales, dolphins.

Fish are vertebrates They have a backbone They are cold blooded They have fins They use gills to breathe e.g., cod, eel, goldfish, trout, salmon, sharks

Birds are vertebrates They have a backbone They are warm blooded They have feathers They have beaks They lay eggs. e.g. Ostrich, chicken, pigeon, sparrow, blackbird

Reptiles are vertebrates They have back bones They are cold blooded They have scaly skin They live on land They have lungs for breathing They lay eggs. e.g. snake, crocodile, alligator, dinosaur

Amphibians are vertebrates They have backbone They are cold blooded They have slimy wet skin, They can live in water and on land They have lungs e.g. Frogs, newts, toads

What am I? Mammal, fish, bird, reptile or amphibian? My body is warm and furry. I feed my babies on milk. I give birth to live babies.

What am I? Mammal, fish, bird, reptile or amphibian? My body is moist and smooth. I lay eggs. I like to live in or near water.

What am I? Mammal, fish, bird, reptile or amphibian? My body is warm and covered in feathers. I lay eggs which hatch out into chicks.

What am I? Mammal, fish, bird, reptile or amphibian? My body is covered in hair, not feathers. I feed my babies on milk. I do not lay eggs.

What am I? Mammal, fish, bird, reptile or amphibian? My body is covered in dry scales. I lay eggs.

What am I? Mammal, fish, bird, reptile or amphibian? My body is cold to touch and covered in scales. I lay eggs. I use gills to breathe with under water.

What am I? Mammal, fish, bird, reptile or amphibian? My body is moist and smooth. I lay eggs. I like to live in or near water.

What am I? Mammal, fish, bird, reptile or amphibian? My body is covered in dry scales. I lay eggs.

What am I? Mammal, fish, bird, reptile or amphibian? If you stand very close to me, you will see my body is covered in hair. I feed my babies on milk.

We can use keys to help us put things into groups. Branching keys let you make a choice at each question.

 Use the classification key.  Look at the alien pictures.  Can you find their names?

Alien Answers

 In pairs.  Look at the branch key.  Put the correct pictures in the spaces.  Check somebody else's.
