Introduction:
In this lab, you will study interactions that take place between biotic and abiotic factors in a model world.
Problem:
Subject : Earth Science
Topic: Biotic and Abiotic relationships
Grade Level: 6th Grade

Science:
Focus on Earth Science: Populations and Communities
5. Organisms in ecosystems exchange energy and nutrients among themselves and with the environment.
a) Energy entering ecosystems as sunlight is transfered by producers into chemical energy through photosynthesis, and then from organism in food webs.
b) Over time, matter is transfered from one organism to another in the food web, and in between organisms and the physical environment..
c) Population of organisms can be categorized by the functions that they serve in an environment
d) Different kinds of organisms may play similar ecological roles in similar biomes.
e) The number and types of organisms an ecosystem can support depends on the resources available and abiotic factors, such as quantity of light and water, range of temperatures, and soil composition.
Instructional
Objective
Students will be able to :
* Build a model of an aquatic ecosystem.
* Predict whether the habitat will meet the organism's needs
* Make inferences about how the model ecosystem operates
Student
Activities
Introductory
Activity
1.
Pretest
Students will complete a pretest to check for prior knowledge on topic.
2.
Students will read pgs 576 - 584 in their Prentice
Hall Earth Science Book. Background information is very important to this
activity.
Enabling
Activity(ies)
3.Assign
Students Living Things and the Environment Worksheet and check for understanding.
4.Students
Will complete corresponding workbook pgs for Chapter 18 section #1
5.Students
will complete section vocabulary sheet.
Culminating
Activity
6.Students
will make a closed ecosystem model that will show that organisms(biotic
and Abiotic) can live an survive with their needs being met.
Assessment
Students will complete a set of analyze and conclude questions to check for understanding. Results
After implementing your lesson (sometime between January & March), insert a chart of your pre-test, post-test, and culminating assessment data.
