Homework 2.1

Asgmt 1-6

Making a PIF

PIF = Personal Idiom file = list of new words

• On your laptop create a new document, call it: 'PIF Biology'
• Make a table like the example
• If you find/read/hear words during the lessons that are unfamiliar/unknown/difficult, add them to your PIF!
• Make sure to save the document well! You will use it throughout the year!

Scan the chapter

Use your book and laptop/notebook

• Go to chapter 2.1 on pages 30-34
• Quickly scan the text for difficult/unknown words
• Make a list of all the words you don't know/understand, add these to your PIF
• Add descriptions and/or synonyms of these words during the lesson

To classify : 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: Ladybird

• 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.

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 leftrow 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 became. 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

4 kingdoms

• Bacteria
• Plants 
• Animals
• Fungi

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

In which of these groups can you find the most different organisms?

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

These words I'll add to my PIF
