Ecological Interactions: Symbiosis Want Ad

Transcription

1 Students show their understanding of symbiotic relationships: Mutualism, Commensalism, and Parasitism, by creating a classified advertisement or want ad in which an organism in a symbiotic relationship is looking for the other organism.

2 Name: Background: Relationships aren t always love-love in biology, nor are they always love-hate. Relationships among organisms can take on many different meanings. Coevolution is the result of an association between two species in which they evolve together and develop such a close relationship that one needs the other for survival. If both organisms benefit from the relationship, it s called mutualism. If one benefits, and the other gets nothing, it s called commensalism. However, if one organism benefits while the other is harmed, then the relationship is considered parasitism. Objective: To show your understanding of symbiotic relationships. Atlanta Journal Constitution Want Ads WANTED: LAZY PUP WITH SHORT NAILS Desperately seeking a parasitic relationship. I am a flea with a thin body and springy legs who can jump 1,000 times my own body size! I am in search of a dog with long fur for me to cuddle up in, thin skin for me to bite, and short nails to keep from scratching me. I need your help because your blood is my nutrients and I need it to keep me alive. In return, I promise to give you the heebie jeebies and plenty of scabby bites to scratch and keep you busy! ME YOU US TOGETHER + =

3 Name: What You Do: Work alone or with a partner to create a classified advertisement/want ad for a job opening in which an organism in a symbiotic relationship is looking for the other organism. The ad should be based on mutualism, parasitism, or commensalism. The ad should be from the point of view of the organism that benefits from the relationship (for example, if the relationship is parasitism, the organism getting harmed wouldn t be seeking out the organism that would harm it). The ad can be done as a PowerPoint presentation, brochure, newspaper ad, magazine ad, poster, prezi presentation, glogster, etc. Please review your presentation options with your teacher. Headline Describing Job - You must have AT LEAST the following criteria: Catchy headline to grab attention ( points) A line describing your relationship (mutualism, parasitism, commensalism) ( points) A line about who you are and the qualities you possess ( points) A line about the type of organism you need for the job (Qualifications.) ( points) A line about why you need this service ( points) A line describing what you will give the organism in return for his or her services. ( points) Picture accompanying advertisement - You must have AT LEAST the following criteria: A picture showing you, the organism in search of the other organism ( points) A picture showing the organism you are in search of ( points) A picture showing the two of you together in your symbiotic relationship- can be handdrawn ( points) Neat and Colorful ( points) Materials to use To create this ad, use construction paper, copy paper, magazine/newspaper cutouts, clip art, computer graphics, photographs, hand drawn images, etc. Use the template on the following page to record your research and ideas for your symbiosis want ad.

4 Name: What Did You Find? This Project is worth: points and is due: The relationship I was assigned is: After researching, I have determined that the type of symbiosis represented by this relationship is: Notes: Do you have the following? Check it off: Catchy headline to grab attention? One line describing your relationship (mutualism, parasitism, commensalism)? One line about who you are? One line about the type of organism you need for the job (Qualifications)? One line about why you need this organism? One line describing what you will give the organism in return for his or her involvement (if nothing will be given, please say that)? A picture showing you, the organism in search of the other organism? A picture showing the organism you are in search of? A picture showing the two of you together in your symbiotic relationship- can be handdrawn? Neat and Colorful?

5 Teacher s Guide What You Do: Below you will find a list of possible symbiotic relationships. They are grouped according to difficulty in finding information. You can utilize this leveling by giving students who need scaffolded lessons the easier to research materials, and those students who need more of a challenge those relationships that are more complex and abstract. Our suggestion is to cut out the list below into strips and place into a basket or hat for random selection by students, or you may assign relationships as you see fit.
