Interactions Among Organisms

LTLT#3:  I can develop, communicate, and justify an evidence-based explanation for the evolution of organisms and environments by analyzing and interpreting data from the fossil record. LT: I can describe the ways in which organisms interact with each other. Criteria for Success: ·      I can define the five ways in which organisms interact with each other. ·      I can identify examples of species interactions in the world. Agenda: Warm up Interactions list Quick Notes Matching Game Video Segments Organism Interactions Game Debrief

   Homework
  

Warm up: How do animals act around each other? What are different types of interactions between organisms? *Share outs… Q: Are there some animals that live near or on other animals? Q: How do you think these animals interact with each other? We’re going to focus on different types of species interactions. We have lots of ideas…write them on stickys, and we’ll try to classify them. Interactions List on Board: (poster paper) *let’s group these interactions… *Commensalism (orange) *Mutualism (Mutalism) *Parasitism (Yellow)   Quick Notes                               *Symbosis is the term for 3 types of relationships. This is the long-term interaction between species that live closely together)   SHOW: Clip from finding Nemo http://www.youtube.com/watch?v=eWXOurnVTYg What is the relationship between Nemo and the sea anemone? Matching Game                        Each table will receive a packet of interactions of one of these types of symbiotic relationships. *hand out notecatchers… Your job: 1.     Put the cards together in the correct interactions 2.     Identify what type of symbiotic relationship your table has. Share out. Write down examples from the other groups as they share out. Let’s add onto our big list board…   Video Segments: Clip 1: Sharks & Turtle Clip 2: Unlikely Travel Companions Clip 3: Sharks and fisherment http://www.pbs.org/wnet/nature/lessons/symbiotic-strategies/video-segments/1496/ Video Clip 4:  How has the relationship between humans and sharks changed? (When humans fished for sharks for subsistence and on a small-scale basis, there was no threat to the continued survival of sharks. With the recent dramatic increase in shark fishing that has resulted from the demand for shark fins and shark cartilage, shark populations worldwide are in danger of collapse). Let’s add to our chart on the board… Interactions Game Teammates, neighbors, thieves, predators & Competitors *Pull a card out of the organism bucket from Ms Mac *Take your organism card and find a teammate with a different organism *Write down both organism on your noteacatcher    *Describe the interaction Debrief: *review chart on the board These are all examples of species coexisting. And these relationships have evolved over a long time. ALL of these relationships are absolutely essential to maintain balance in an ecoysystem. The animals have had to adapt to these changing environments. Q: What are some events or behaviors that might throw this balance all out of wack? (ex: human actions, climate change, pollution, major geological events) *What about the relationship between Humans and animals?
