Virtual Laboratory

How are the animals on the screen sorted?

• The animals in the groups on the screen are sorted by the place they live.

• There are forest animals, ocean animals, and African river animals. 

There are forest animals, ocean animals, and African river animals. 

• The animals in the groups on the screen are sorted by the place they live.

• you may group them by the parts they have,

• size,

• whether they have flowers or not, and

• where they grow

What are invertebrates?

Invertebrates are animals without a backbone or a spine. 

What are vertebrates?

Vertebrates are animals with a backbone or spinal column.

Fill in the Blank

Which group do you think you belong to: vertebrates or invertebrates?

Humans are vertebrates, because we have backbones.

Multiple Choice

What do you think is special about vertebrates?

• they have spine

• they are swine

• they have no backbone

What do you think is special about vertebrates?

They have a spine, which gives them support and shape.

What are fish?

Fish are vertebrates. They have scales, fins, and tails. They have gills to breathe underwater.

What are reptiles?

Reptiles have backbones and spines. They are born on land and live on land. They have scaly skin and sometimes have clawed feet. 

What are mammals?

Mammals are vertebrates. They have lungs to breathe and hair or fur on their bodies. They give birth to live babies. The mother mammal feeds the baby milk. 

What are birds?

Birds are vertebrates. They are covered with feathers and have wings and lungs. Their babies hatch from hard-shelled eggs. 

What are amphibians?

Amphibians are vertebrates. They are born in the water with gills and then develop lungs as adults. Their babies hatch from eggs and some are born live. 

What are arthropods?

Arthropods are invertebrates. They are the largest group of animals in the world. They all have six or more jointed legs and segmented bodies. 

What are insects?

Insects are invertebrates and arthropods. They have three life stages: egg, larvae, and adult.

Multiple Choice

What are both invertebrates and arthropods?

• amphibians

• reptiles

• insects

• mammals

Multiple Select

How will you sort the animals in this activity?

• by what kind of animal they are, and by the kind of habitat in which they live

• By identifying if they are meat-eaters or plant-eaters

• by telling if they have a backbone or not

Do you have lungs or gills to breathe?

Humans use lungs to breathe; fish have gills to help them take in oxygen from water.

Multiple Choice

Does a baby puppy eat dog food or drink milk from its mother?

• baby puppy eats dog food

• baby puppy drinks milk from its mother

• baby puppies prefers dog food buy humans give them cooked food

Multiple Choice

Do dogs lay eggs? Are puppies hatched from an egg?

• Sometimes, dogs lay eggs.

• No, dogs give birth to live babies.

• Dogs do lay eggs but sometimes give birth to live babies.

What is classification?

Classification is the grouping of things by things about them that are the same or different.

How are you going to classify, or sort, the animals in your investigation? 

To sort the animals, you need to find out about them. In this investigation, you will examine the animals to figure out which animals belong in which group. 

Why is classifying or sorting living things important?

When we sort by different characteristics we can make sense of the world around us. We can make sense of the different kinds of animals and plants. 

Multiple Choice

Where do humans fit into the classification of living things?

• vertebrates

• invertebrates

Where do humans fit into the classification of living things?

Humans are vertebrates, animals having backbones, and are mammals that have hair on their bodies, give live birth, feed their babies with milk, and have lungs to breathe.

What are arachnids?

Arachnids are all arthropods that have eight legs. Spiders are arachnids.

Multiple Choice

How can you tell the difference between insects and spiders?

• spiders crawl and insects fly

• spiders eat insects

• spiders have eight legs and insects have six legs

If conifers have seeds, why are they classified as nonflowering plants?

• Conifers have seeds enclosed in a cone structure, not a fruit, and they do not produce flowers. 

Multiple Select

Are all seed producing plants also flowering plants?

• yes

• no

No, some seed producing plants like conifers are nonflowering.
