3. Student Activity

Choose from one of the following organism pairs to study for Dr. Darwin.

1. Oxpecker and Rhino/Ox2. Shark and Remora3. Human and Human4. Bees and Flowers5 . Your own (must be approved by Dr. Darwin)

You need to answer the following tasks or questions:1. Identify the two organisms.

2. Explain how their interdependent relationship works.

3. Is it a mutualistic (positive for both) or parasitic (positive for one and negative for the other).

4. How does their relationship effect other organisms?

Use this document to the right to record your answers.

4. Assessment ActivityA good ecologist shares their findings with the world. You now have the opportunity to share all the information you have learned !

Your final question that you must answer is:

If one of these organisms was eliminated, how could it change the life of the other organism and the environment?

Your choice:Newsletter:

1. Use your student activity sheet to help you write your newsletter.

2. Use this form to create your final copy that will be printed with the monthly newsletterCreate a video to share on your local morning announcement program.

Scoring Tool:Look at the scoring tool to see what is expected for the project.

5. Enrichment Activities

Write an email to the Governor of Maryland explaining your findings. You will want to include:1. What you found out about your organisms interdependent relationship.2. Explain what will happen if one of the organisms is eliminated.3. Propose ideas about what the Governor can do to keep this from happening.

6. Teacher Support MaterialsGrade Level and Content Area: Grade 2 Accelerated group

Common Core State Standards

Reading: 1. Read closely to determine what the text says explicitly and to make logical inferences from it; cite specific textual evidence when writing or speaking to support conclusions drawn from the text.

Writing: 7. Conduct short as well as more sustained research projects based on focused questions, demonstrating understanding of the subject under investigation.

Standards for the 21st Century Learner 1.1.6 Read, view, and listen for information presented in any format (e.g. textual, visual, media, digital) in order to make inferences and gather meaning.2.1.3 Use strategies to draw conclusions from information and apply knowledge to curricular areas, real-world situations, and further investigations.

ISTE NETS - National Educational Technology Standards for Students

3. Research and Information Fluency: Students apply digital tools to gather, evaluate, and use information.b. Locate, organize, analyze, evaluate, synthesize, and ethically use information from a variety of sources and media.

4. Critical Thinking, Problem Solving, and Decision Making: Students use critical thinking skills to plan and conduct research, manage projects, solve problems, and make informed decisions using appropriate digital tools and resources. c. Collect and analyze data to identify solutions and/or make informed decisions

Maryland State Curriculum: Life Sciences

3.F.1.a Investigate familiar and unfamiliar habitats describe how animals and plants found there maintain their lives and survive to reproduce.

3.F.1.c Explain that animals and plants sometimes cause changes in their environments.

Time Frame: 2 – 50 minute lessons in the computer lab.

Differentiation: Direct students to use comprehension tools such as: audio read-aloud, embedded dictionaries, and links to related articles, and videos.

Learning Styles:

Auditory, Visual, Reflective, Sequential, Field

Independent, Global

Notes to the teacher:Objective: Students will research two organisms that are interdependent in order to explain if they can be truly interdependent.If you have questions about implementing a slam dunk into your teaching, ask your Library Media Specialist for assistance.Students will be able to save their work onto the student drive. You may need to show students how to do this and create a folder for them as well. A gold star is higher reading level, some of the texts offer a read aloud for students - A silver star was given for the videos since they are easy to follow along with. You will need to review what an organism is prior to assigning this project.Last updated: July 2014
