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

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:
