This part of the ecology unit seems deceptively simple. Students should be familiar with what predation, competition and symbiosis are. However, interpreting paragraphs describing these interactions and the data that goes with the different models can prove challenging for students. That is why I save streamlined what students need to know and be able to do in this section. I have also given them some strategies to use to help them decipher the different types of interactions. As always, the google slides lesson guides students through the lesson. I would use this as a digital interactive notebook for students. Make sure to scroll down to the bottom for a video preview. Here is break down of what this remote lesson contains: Title Slide Slide 1: Interspecific Interactions- Information on the different types of predation presented in a graphic organizer. Slide 2: Interspecific Interactions- Information on competition in animals and in plants Slide 3: Competition Model- Introduction to the rabbit and plant simulation found here Slide 4: Competition Model 1- Students use the link to collect data for the standard setting of the simulation. They then paste a screenshot of the graph and answer a question. Slide 5: Competition Model 2- Plant competition is explored. Students use the link to collect data when they increase growth rates of the grass in the simulation. They then paste a screenshot of the graph and answer a question. Slide 6: Competition Model 3- Rabbit eating preferences are explored.Students use the link to collect data when they add in a bitter taste to one of the plants in the simulation. They then paste a screenshot of the graph and answer a question. Slide 7: Competition Model Analysis Question- Students apply their knowledge to answer questions on invasive plant species Slide 8: Symbiotic Relationships- Information on the different types of symbiotic relationships. Slide 9-13: Good Buddies, Bad, Buddies and Uncaring Buddies- Students read scenarios about different symbiotic situations. They they fill out a table to help them determine this. Slide 14-16: Ecological Balance of Sharks- Students watch 2 PBS video clips. Video 1 clip here and Video clip 2 here. They then answer questions about what happens when ecological balance is disrupted. Interested in the lesson? Check out my TpT page.
