How are CRQs Scored?
These questions are scored on a scale of 0-2 points.
The CRQ
Example 1
The theory of evolution is supported by the walking stick population by showing that species tend to be fit for their environment. On striped chamise plants, you will find walking sticks. Which is there way of camouflage to hide from predators. Also, on unstriped lilac plants you will find unstriped walking sticks, which blends in with the unstriped lilcac plant.
Example 1
Score: 1
Reasoning: the student correctly describes the theory of evolution and how it relates to the walking sticks. However, it fails to answer the 2nd question about how the population would change.
Example 2
Its supported by the way the walking stick looks.
The chamise population would mix in with the lilac population and they would form another population
Example 2
Score: 0
Reasoning: This response does not clearly describe how the stick population supports the theory of evolution. Also, it mistakenly states that the populations would mix.
Example 3The theory of evolution is supported by the walking
stick
population because the striped walking sticks live on
striped chamise plants and are able to camouflage from
predators so they can survive and reproduce. The non
striped walking stick population lives on the unstriped
lilac plants for the same reasons. If the lilac population
was rapidly reduced by a virus, then the non striped
walking stick population would decrease. Over time,
there would only be striped walking sticks.
Example 3
Score: 2
Reasoning: This response is complete and accurate. The first point is earned by explaining how the populations support evolution by discussing camouflage and fitness. The second point is earned by correctly predicting that the non-stripped population would decrease.
Unit 6: Ecology
Ecology
Eco = “our” house/earth
ology = the study of
Ecology = the study of the earth.
Kingdoms
Scientists group all living things based on their relatedness and on their traits.
Kingdoms
Kingdom: a group of related organisms based on their cell type, mobility, and reproduction.
There are 5 kingdoms (that we need to know).
Eubacteria
Features: prokaryotes, unicellular, asexual. Cannot move.
Example: bacteria
Pneumonia Bacteria
E. Coli Bacteria
Protists
Features: eukaryote, multicellular and unicellular, asexual. Some can move.
Example: aemoba
Animal-like
Fungus-like
Plant-like
Fungi
Features: eukaryote, multicellular, eat dead organisms, asexual/sexual. Cannot move.
Example: mushroom
Plantae
Features: eukaryote, multicellular, make energy from sun, sexual. Cannot move.
Example: tree, grass
Animalia
Features: eukaryote, multicellular get energy from eating other organisms, sexual. Moves.
Example: deer, insect, fish
Gallery Walk
In the coming slides, you will see clues about mystery organisms.
You must classify each mystery organism and state why you made your classification.
Station 1: Mystery Organism
I am multicellular.
I use sunlight to make energy.
I make my own glucose food from sunlight.
What Kingdom do I belong to?
Station 2: Mystery Organism
I am multicellular.
I eats grass.
My species have males and females.
What Kingdom do I belong to?
Station 3: Mystery Organism
Heliobacter pylori
What Kingdom do I belong to?
Station 4: Mystery Organism
All eukaryotes Some single cell and some many
cells.
What Kingdom do I belong to?
Station 5: Mystery Organism
What Kingdom do I belong to?
Shoe ClassificationDirections:
1. Put the shoes in 2 groups based on if they are open/closed toed.
2. Now group the shoes by whether they have laces.
3. Give each shoe a specific name.
Classification
Scientists group and name organisms so they can be identified and so they can be compared to their relatives.
Classification
There are 7 levels of classification.
Mnemonic
King Philip Came Over For Grape Soda
Kingdom Example: Animalia
bobcat
jellyfish
horned beetle
The broadest of the groupings.
Phylum More specific or
smaller than kingdom
Example: Chordata: animals with backbonesBobcat
mouse
toad
lizard
Class more specific
than phylum
Example: Mammalia (mammals)
Bobcat
Horse
Rabbit
Order more specific
than a class
Example: Carnivora
bobcat
wolf
bear
Family more specific
than order
Example: Felidae or Feline Family
Bobcat
Tiger
House cat
Genus More specific
than family, 1st word in scientific name
A group of VERY similar species
Example: Lynx
Bobcat
Lynx
Species
Most specific, 2nd word in scientific name
Example: Lynx rufus or bobcat
Bobcat
Hierarchical Classification Taxonomic categories
Kingdom (big) King Phylum Philip Class Came Order Over Family For Genus Grape Species (small) Soda
Classification
The Genus Species of an organism is its “name”.
Homo Sapiens Genus Species
Example
Puma Concolor
1. Which word is the genus name?
2. Which word is the species name?Puma

The Classification System
Turn and Teach When I say “Go”…
1. Person closest to the door at your table will say the 6 steps to their partner 2 times.
2. Person farthest from the door will write down the steps as their partner says them

memorized? Lets see it!

Exit Ticket
1. Using the mnemonic we learned today, write out the taxonomic categories from largest to smallest. 2. Identify the kingdom of the following organisms:A. A large organism that moves and eats ratsB. Unicellular organism, no nucleus: C. Mushrooms are an example: D. Does not move and gets energy from the sun:
