1. PowerPoint Differentiated Unit 4 Week 1 Group A Mr. Smet’s Scientific Studies

2.  This Power Point presentation has been made to walk you through the worksheet. It will answer a short number of the questions from your packet but also go through the key points of answering the other questions with examples.  Work with urgency! How this works

3. Section 1 Symbiotic Relationships Review

4. Section 1 Directions  Read through the following slides to refresh your memory of symbiotic relationships. Write down the definitions of each of the terms in Part 1 of your packet.  Note: Pay close attention to the descriptions of these relationships. It is very important to recognize when something is benefitted, when something is unaffected, and when something is harmed.

5. Predator/Prey Definition: Any interaction in which one organism consumes another. Example: Lions hunt for hyenas, their food.

6. Competition Definition: Two species are hurtful to each other because they need the same resource, but there is not enough. Example: In forests, all plants need sunlight to grow and they compete for it. The tallest trees “win” this competition.

7. Symbiosis Definition: Any interaction in which two organisms live together. There are three types: Commensalism Mutualism Parasitism

8. Section 2.1 Summary – pages 35 - 45 Mutualism Definition: A symbiotic relationship in which both species benefit is called mutualism. This little fish is helping me by cleaning my teeth!!! Yeah!!! I’m eating the big fish’s food so he’s helping me too! Yeah!!!

9. Section 2.1 Summary – pages 35 - 45 Commensalism Definition: A symbiotic relationship in which one species benefits and the other species is neither harmed nor benefited. Example: In this picture, Spanish moss is growing on the trees. The moss benefits because it has a place to live, and the tree doesn’t care.

10. Section 2.1 Summary – pages 35 - 45 Parasitism Some interactions are harmful to one species, yet beneficial to another. Some interactions are harmful to one species, yet beneficial to another. A member of one species benefits by living inside another, which is harmed is called parasitism. Definition: A member of one species benefits by living inside another, which is harmed is called parasitism.

11. Section 2 Classifying Relationships in Videos

12. Section 2 Classifying Relationships in Videos #1  During this section you will use the definitions that you wrote in Part 1 to answer four questions about each of 6 videos that you are about to watch.  You will be watching six videos that describe symbiotic relationships (mutualism, commensalism, and parasitism– not predator/prey or competition.)

13. Section 2 Classifying Relationships in Videos #2 Directions: Answer the questions in your packet using the videos linked from the following slides. The first video will be used as an example. It describes two symbiotic relationships and both are described in your packet to answer the questions.

15. Section 3 Classifying Relationships in Text

16. Section 3 Classifying Relationships in Text #1  During this section you will answer the same questions as you did in the last section, but this time you will be using text instead of videos.  You will be reading two descriptions of symbiotic relationships (mutualism, commensalism, and parasitism– not predator/prey or competition.)

17. Section 3 Classifying Relationships in Text #2  At this time, you may begin working through questions 1-4 for each of the descriptions in A and B.
