1. Classification of Organisms
L.O: How to classify organisms, use the binomial naming system and understand why it is useful.
Grade 4: Describe what classification is, classify animals into groups and write an organism’s name correctly using the binomial system.
Grade 6: Describe the classification system developed by Carl Linnaeus, identify genus and species from a scientific name and explain why a binomial naming system is useful.
Grade 8: Use the Linnaean system to name the groups that given organisms belong to.

2. Odd one out Which is the odd one out and why?
Ostrich – NOT A MAMMAL BUT ANY OTHER SENSIBLE SUGGESTION

3. Odd one out
Which is the odd one out and why?
A bird not a mammal

4. Classification All living things can also be grouped. But why bother?
Makes them easier to study
Allows us to make sense of the living world
Helps us understand how living things are related.
Helps us recognise biodiversity
Gives scientists a common language in which to talk about it.

5. Carl Linnaeus Swedish botanist Born: 1707 Died: 1778 (aged 70)
Classification as we know it today began with Linnaeus. He grouped living things based on their structure and characteristics. He made very careful observations and classified organisms into a hierarchical structure…

9. For example:
KINGDOM: Animalia
PHYLUM: Chordata
CLASS: Mammalia
ORDER: Carnivora
FAMILY: Felidae
GENUS: Panthera
SPECIES: leo

11. Hey Carl, why do we need these confusing double Latin names?
That’s my idea too! Common names are fine for normal conversation, but it can get confusing…

12. The blue crab is one of many blue species.
In the Indian River Lagoon alone, there is the blue crab (Callinectes sapidus),
the lesser blue crab (Callinectes similis),
the red blue crab (Callinectes bocourti),
the ornate blue crab (Callinectes ornatus),
and the blue land crab (Cardisoma guanhumi).

13. Well heck! That IS confusing!
I know, right!?
And sometimes, one species has many common names depending on the region..
Well heck! That IS confusing!

14. For example, the striped mullet,  Mugil cephalus, is found all over the world, and has a variety of common names ?

15. Geez…thanks Carl. You’ve totally saved the day!
AND…there are some species that are so obscure, they don’t even have a common name.
Geez…thanks Carl. You’ve totally saved the day!

16. Just remember: The first (genus) word begins with a capital letter, the species name doesn’t.
Like Homo sapiens

17. And it’s always shown in italics
And it’s always shown in italics. If you are handwriting the name, then underline it.

21. Reflective Learner Summary so far:
Who invented the classification system we use today?
Why is useful to have a classification system?
Why do we use Latin binominal (two name) names for species?
What are the rules for writing a species Latin name?

22. Summary so far:
Who invented the classification system we use today? Carl Linnaus
Why is useful to have a classification system? It makes living things easier to study, allows us to make sense of the living world, helps us understand how living things are related and recognise biodiversity. It gives scientists a common language in which to talk about it.

23. Summary so far:
3. Why do we use Latin binominal (two name) names for species? Some common names are not specific enough, One species could have many common names depending on the region and some species don’t have a common name.
4. What are the rules for writing a species Latin name? The genus has a capital letter, the species has a lower case, they are written in italics or underlined if hand written.
Homo sapiens
