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 2 nd 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 3 The 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 Classification Directions: 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.

Kingdom Example: Animalia bobcat jellyfish horned beetle The broadest of the groupings.

Phylum More specific or smaller than kingdom Example: Chordata: animals with backbones Bobcat 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, 1 st word in scientific name A group of VERY similar species Example: Lynx Bobcat Lynx

Species Most specific, 2 nd word in scientific name Example: Lynx rufus or bobcat Bobcat

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 rats B. Unicellular organism, no nucleus: C. Mushrooms are an example: D. Does not move and gets energy from the sun:
