Who Goes There? Friend or Foe?

Symbiosis refers to the interactions between organisms. There are 3 types of symbiosis: parasitism (one organism is helped, the other is harmed), mutualism (both organisms are helped) and commensalism (one organism is helped, the other is unaffected either way)

Note: Predation and parasitism are similar, however, in parasitism one organism is HARMED and in predation one organism is KILLED AND EATEN.

NGSS Standards Covered

  • MS-LS2-1 Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.
  • MS-LS2-2 Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems.
  • MS-LS2-4 Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.

Ecological Relationships Learning Objectives

  • Describe the roles competition and predation play in shaping communities
  • Identify three types of symbiotic relationships in nature

I Can Statement

"I can explain different ways organisms in ecosystems interact with each other."

Ecological Relationship Speed Dating Lab Proper:

Materials: per partner pair

Teacher prep- print and cut organism cards before class begins.

Copy of worksheets for each student.

Ecological Relationship Speed Dating Activity Procedure:

  1. Teacher will tape an Organism Card on each student’s back without showing the students.
  2. Walk around the room and meet another “organism”. Each student checks the picture on the back of the other student.
  • First, give hints to the other student to help them guess what organism they are. Then they will give you hints, and you must guess what organism you are.
  • When you both know which organism you are, discuss and decide whether your organisms have a relationship.
  • If they do, go sit down with your partner.
  • If they don’t, find the organism in the class that DOES have an interaction with your organism.
  1. When all the partner pairs have been found and are sitting together, discuss as a class what you discovered.
  2. On your worksheet, choose 6 of the relationships the class found, and document them.

Organism Cards

Teacher will tape one on each student’s back. Keep the secret- don’t let your classmates know what organism they are!

Ecological Relationship Speed Dating Post-Lab Activity:

Part 1 - Speed Dating Worksheet

First, document the relationship between your organism and your partners.

Then, from the class discussion, select 5 more pairs of organisms and document those relationships.

My organism is _____________________  My partner’s organism is ____________________

What is the result for the first organism? Circle it.What are the two organisms?What is the result for the second organism? Circle it.
