Lessongoals

• Remember: I can list the seven main taxonomic groups from largest to smallest, starting with the kingdom and ending with the species.
• Understand: I can explain the need for a classification system and the purpose of the binomial system in naming organisms.
• Understand: I can explain the characteristics (appearance, way of life, and genetics) used to classify organisms into the four major kingdoms.
• Apply: I can correctly write the scientific name of an organism, following the rules of the binomial system (Genus species)

Homework 2.1

To classify something
what does it mean?

Classification in Biology

Biologists order organisms in different groups > they classify organisms

• To do so they use characteristics 

For example:

• Has 4 legs
• Has a nucleus in its cells
• Has 2 eyes
• Can fly
• Is smaller than ...
• etc.

Alphabet: Think-Pair-Share

• Think: Work on the assignment on your own.
• Write all the letters of the alphabet in your notebook in 3 rows
• Use each letter to write the name of a species of organism
• Example NOT: plant BUT: Oak tree, NOT: Insect BUT: Ladybug

• Pair: Compare with your neighbour, do the next assignment
• Make groups that you can classify both your organisms into
• Think of at least 1 characteristic for each group, that all organisms in it have
• Share: Talk about given answers during plenary session.

What is a similarity and a difference between a robin (roodborstje) and a frog?

What is a similarity and a difference between a human and a cow?

Taxons

Biologists order all life into taxons.

Taxons are groups of organisms that show similar characteristics/traits. 

Every organism belongs to multiple taxons.

Example crocodiles belong to the taxons:

animalia, chordata, reptilia, archosauria, crocodilia

Things you can recognize them by. For example:

• Having a nucleus in their cells
• Having 4 legs
• Laying eggs
• Having fur

Their cells have no cell walls 

They have a spine

They are reptiles, which have their own set of characteristics

4 Kingdoms 

• Bacteria
• Plants 
• Animals
• Fungi

Kingdom is a taxonomic group

It contains taxons which are of similar level

The taxonomic group: kingdom contains 4 taxons.

All life belongs to one of these 4 taxons.

Taxonomic group

To order/classify organisms scientist use different groups.

These are called taxonomic groups.

The kingdom is the biggest taxonomic level. Containing a lot of different organims.

The species is the smallest taxonomic level. Containing only a single species of organism

If you move to the right, organisms in a group become more and more similar

Taxon

Each taxonomic group contains taxa (singular taxon).

For example the taxonomic group kingdom contains the taxon animalia (or animals).

Taxons are names used for the different groups of organisms found in each taxonomic group

All organisms shown in the left row belong to the kingdom: Animalia.

They all share characteristics that place them together in this group

The more you move to the right, the more similar organims become. They share more and more of the same characteristics.

The level of species means that organisms in this group are so similar that they can mate and have fertile offspring.

Within the group of species you can sometimes find several breeds.

Take dogs.

All dogs belong to the same species, therefore they can mate and have fertile offspring.

Different breeds of dog can be very different, compare: labrador and a bulldog

Remember:

Kids prefer cheese over fried green spinach

Example

The more you go down in this image the closer related the organisms are.

All organims shown belong to the group shown above them.

Examples: 

• Lions and tigers all belong to genus panthers
• Cats and bats both belong to class mammals

Kids prefer cheese over fried green spinach

Kingdom, phylum, class, order, family, genus, species

Common name used by everyone

Scientific name used by scientists, tells you genus and species

Common name	Scientific name
Magpie	Pica pica
House cat	Felis catus
European lobster	Homarus gammarus
English oak	Quercus robur
Fly agaric	Amanita muscaria

Genus

Species

binomial system

bi = 2   nomial = name

system in which you give 2 names

The scientific name consisting of genus and species

You see a cell with chloroplasts, this is probably the cell of a

1. Animal
2. Plant
3. Bacteria
4. Fungi

Which of these taxonomic groups contains the biggest diversity (=most different) of organisms?

1. Species
2. Class
3. Family
4. Order
