Announcements/Reminders

Announcements/Reminders • Don’t forget to bring in your scrap of fabric for the Global Literacy Quilt • Reading Rocks Day tomorrow! • Bring in last week’s HW for -20pts • HW Turn in Rates: • Block 1: 10/20 • Block 2: 11/20 • Block 3: 9/20

Bellringer Scenario: Oh no! Jake just stole James' lunch! Now James is sitting at lunch, sad and hungry. 1. Who benefited from this encounter? 2. Who is harmed from this encounter? 3. Did anyone die because of this encounter? 4. Think of an example from the animal kingdom that is similar to this scenario.

Symbiotic Relationships (3) • A close relationship between two organisms is called symbiosis. • In short, symbiosis means living together. Based on its definition, do you think organisms in symbiosis want to kill each other? No! At least one organism is dependent on the other! (...just like any other relationship).

Yes and no in sign language

Real World Example • In the book/movie, Holes, kids have to dig holes as punishment. Zero digs Caveman's hole for him, in exchange to be tutored in reading. • Does Caveman benefit from this relationship? • Does Zero benefit from this relationship? • ...did anyone die becauseof this relationship?

Mutualism • A symbiotic relationship where both organisms benefit from the relationship. This little fish is helping me by cleaning my teeth!!! Example in Nature Tee hee, I’m eating the big fish’s food.

Mutualism Organism B Organism A

Real World Example • Taylor was falling asleep in class. As he is taking the exit ticket, he realizes he could fail. Panicking, he copies Jessica's answers who sits across from him. Neither are caught cheating. • Did Taylor benefit from this relationship? • Did Jessica benefit from this relationship? • ...did anyone die because ofthis relationship?

Commensalism • A symbiotic relationship where one organism benefits from the relationship, and the other is neither harmed or benefited. I ride on the cow's back and eat up insects that are kicked up from the ground when the cow eats. Example in Nature I don't even notice this crazy bird!

Commensalism Organism B Organism A

Real World Example • Sarah forgot her lunch at home. When Gloria isn't looking, she takes her lunchbox. Sarah enjoys her turkey sandwich as Gloria is left hungry. • Did Sarah benefit from this relationship? • Did Gloria benefit from this relationship? • ...did anyone die because ofthis relationship?

Parasitism • A symbiotic relationship where one organism benefits from the relationship, and the other is harmed, but not killed. Example in Nature I feel pain and lose blood. :( I suck your blood to feed myself!

Parasitism Organism B Organism A

Guinea worm travels through water and then comes out through your legs/feet when it is ready to release more eggs.

Tapeworms can be spread through contaminated, undercooked food! For example, this is a tapeworm that came out of this fish. If you had not cooked this fish all the way and then eaten it, you might not have killed the worm and then the worm could live inside of you.

Let’s Review • M C P

Let's Review! Clownfish hide in poisonous sea anemones, whose poison protects them from larger fish. Nothing happens to the sea anemones. p c m

Let's Review! Flowers provide food for insects. Insects spread the seeds of flowers. p c m

Let's Review! This bird is eating ticks off of this impala. How are the bird and the impala related? p c m

Let's Review! This leech is sucking up blood from this human's leg. p c m

Practice • You are an animal behavior professor and you are about to give a lecture on symbiosis • Complete your ‘field guide’ to show your students before they arrive to class

Create an analogy • Create a scenario that represents each of the three types of symbioses • 3 sentences for each • Clearly state who benefits/is harmed

Exit Ticket • Complete silently and independently • Raise your hand quietly when you are done • Good Luck!

Announcements/Reminders • Reading Rocks day today  return to homeroom class instead of enhancements • We will be sharing our poetry projects ‘coffee shop’ style • Continue to bring in old fabric for our global literacy quilt • Congrats on yesterday’s exit tickets! 

Grab data folders to track yesterday’s ET Unit 6: Day 8 Practice with symbiotic relationships

Mad Minute • Answer as many as you can correctly in one minute • Commensalism, competition, mutualism, parasitism, or predation • Ready, set, go!

Analogies • What is an analogy? • An analogy is a comparison between two things • Ex: “Life is like a box of chocolates, you never know what you’re going to get”

Create your own analogy • You will create an analogy for each of the 4 interactions in nature • You want to compare them to your everyday life through a short story • Ex: My sister and I were rushing to get ready for school when my mom yelled, “If you and your sister get this house clean by the time I get back from work, I’ll pay you $10.” I really hate doing dishes; so, I told my sister, “You do the dishes and I’ll vacuum and we’ll split the money 50:50.” She agreed and we both benefitted when my mom got home”

Create your own analogy • Your finished product will… • Have 4 analogies, each on their own paper, written neatly • Each analogy will be at least 3 sentence and be descriptive, explaining who benefits/is harmed • Each analogy will have a colored drawing to represent it on the back • Your classmates will then try to guess the relationship based on your analogy/drawing • Do these with care…it is the last grade of the term!
