Lesson 2 - Hiding Organisms

Lesson Plan

State Standards:

High School Evolution and Biodiversity 5.1: Explain how evolution is demonstrated by evidence from the fossil record, comparative anatomy, genetics, molecular biology, and examples of natural selection.

Essential Question:

How does natural selection work?

Lesson Question:

Why do organisms “hide?” What advantages and or disadvantages do organisms have by “blending in” to their environment?

Introduction:

There are hundreds and thousands of different organisms all around the world and certain organisms can only survive and reproduce in specific locations, but why? How can organisms only adapt and reproduce successfully without being wiped out by a predator? Wouldn't there be predators in every community?

Task:

Your task is to determine just HOW organisms “beat out” their predators! What do organisms do to successfully reproduce and survive (Natural Selection) in their ecosystems?

Lesson Experiences:

Process:

As indicated by the teacher proceed to your assigned group. (Groups are generated at random each student receiving a number 1-6)

There are SIX stations, each of which have a different organisms community (recreated by the teacher) presented. In each of the communities you will find the organisms that live in that ecosystem. You will have both a Web 2.0 image as well as a hands on image for your observations.

Your task is to answer the following questions with detailed observations:

ALL observations will be recorded on the provided data sheet. (This will be handed in and graded as 10% of your class participation grade)

Each station will have a computer (already booted up) for you and your group mates to research in detail the organisms that are present and theories as to how all of the organisms survive together. (Great place to start is "Adaptations" on Wikipedia.)

Each station will last no more than 10 minutes (this will take at least 2 class periods to complete all observations).

What is a Prezi: For those new to the Prezi Community below you can find a detailed example of what a Prezi involves and what elements should be included:

How to Create a Prezi

GREAT PREZI EXAMPLE: 3D Backgrounds - Freshwater Shortage by Drew Banks

What elements should be included (Required Elements):

REMEMBER -- Less is more when it comes to a PowerPoint or Prezi presentation. You will still be presenting this information to the class -- USE KEY words!

 

Conclusion:

Reflect on everything that we have discussed over the past 3 days on ecosytems and why organisms adapt to better suit themeselves to their environment, then discuss the lesson questions:


You will complete a one paragraph response that details information learned from your classmates presentations and the notes taken in class. This will be collected and graded as a final quiz grade.

Assessments:

1. Observation sheet - 10pts.

2. Prezi Presentation - 20 pts.

3. Final Quiz to complete what Adaptation is (reflection to the lesson question) - 20 points

Unit total - 50 points.

Prezi - information and Content
The prezi includes NEW and old ecosystem observations and detailed hypothesis
The prezi includes NEW ecosystem but missing observations and detailed hypothesis
The prezi includes NEW ecosystem observations with not additional information
several required elements are missing from the Prezi
Content Accuracy
At least 10 facts on your new ecosystem are displayed
At least 8 facts on your new ecosystem are displayed
Less then 5 facts are present
Less then 3 facts are present
Graphics - Orginality
Graphics used in the prezi reflect an exceptional degree of student creativity in their creation and/or display. All content areas are filled
Some graphics used in the prezi reflect a degree of student creativity in their creation and/or display. All content areas are filled
Few graphics used in the prezi reflect a degree of student creativity in their creation and/or display. most content areas are not filled accurately
Zero graphics used in the prezi reflect a degree of student creativity in their creation and/or display. most content areas are not filled accurately
Organization
Prezi is organized neatly with proper flow (old to new ecosystem - proper build up to the new ecosystem)
Prezi is organized but flow (old to new ecosystem - proper build up to the new ecosystem) is not accurate
Prezi is not organized - flow (old to new ecosystem - proper build up to the new ecosystem) is not accurate
several pieces are missing with no organization at all.
Organization Everett High School Analytical Rubric
The student actively approaches multiple learning styles, clearly connects ideas and answers questions with elaboration.
The student approaches multiple learning styles, connects ideas and answers questions sufficiently.
The student attempts to approach multiple learning styles, connects ideas and answers questions.
The student is unable to approach multiple learning styles, connects ideas or answers questions.

 

 

Resources:

Various organisms that adapt and blend to their communities (all ecosystems) pictures and poster simulations are strongly encouraged.

Computers (each station already booted for students to use at their own pace)

Observation Sheet: Hiding Organisms

Teacher Notes: Teachers should be making continuous laps around the classroom encouraging students to look deeper into their observations ... why are these organisms blending so well, force them to look at other aspects other than just colors!
