Biotic Factors - Cengage Learning

PREASSESSMENT – KNOWLEDGE RATINGS
For my preassessment strategy I have chose to use a knowledge rating checklist.
Knowledge ratings get students to analyze what they already know about a topic. The students are
provided with a survey or checklist to fill out individually. The completed checklists are ultimately
collected by the teacher to assess what previous knowledge or misconceptions the students are
bringing into the biome unit.
A follow-up discussion occurs after students have completed their checklist. Students
should be encouraged to share what they know about the words during this class discussion. Some
leading questions the instructor might ask include: Which are the hardest words? Which words do
you think most of the class doesn’t know? Which are the easiest words? Which words do most of
us know?
Once the checklists have been viewed by the instructor, they should be returned to each of
the individual students. This checklist can then be used as a reference list throughout the unit. In
addition, the checklist could be completed at the conclusion of the unit to show how much
knowledge was learned by each student.

LESSON PLAN – DAY ONE
UNIT
1.
2.
3.
4.
OUTCOMES:
Students will define the term biosphere.
Students will distinguish between populations, communities, and ecosystems.
Students will name the types of abiotic factors in an ecosystem.
Students will name three types of interactions among biotic factors in an environment (i.e.
competition for resources, predation, and symbiosis).
5. Students will list some ways biotic and abiotic factors in an environment interact (i.e.
describe how biomes are determined by climate).
LESSON OBJECTIVES:
1. Students will divide into groups and select a biome to be researched.
2. Students will select individual group roles to complete.
DRIVING QUESTIONS:
** See “BIOME PROJECT” student handout
MATERIALS:
 Overhead transparencies of biome notes – used as a visual aid during the instructor’s
introduction of key concepts
 Overhead projector – used to display the transparencies
 Biome Project Description – this student handout describes the goals and expectations of
the project
 Group Role Evaluations/Rubrics – these student handouts describe the guidelines and
grading rubric that will be used to evaluate the individual portions of the biome project
PROCEDURE:
1. The following procedure is designed to be completed in one 50 minute class period.
2. (Time = 15 minutes) Present the first section of notes to the class using an overhead
projector. The key concepts that will be reviewed or introduced include the definitions of
the biosphere, a population, a community, an ecosystem, and a biome. The instructor will
also compare and provide examples of abiotic and biotic factors of an ecosystem, detailing
the types of interactions that exist between each.
3. (Time = 5 minutes) Hand out the “Biome Group Project” description sheet. Allow students to
read the information silently at their seats. Once completed, have students select the
members of their group, sitting together as a distinct unit. Alternatively, the instructor
may choose to assign students to specific groups. Once students are in their distinct
groups, hand out the “Role Evaluation” sheets.
4. (Time = 10 minutes) Discuss and highlight the key points of the project. Points to
emphasize include:
 Size of groups – three or four members
 Roles and expectations of group members – Writer, speaker, graphic artist, and set
designer (the role of set designer is only to be used in the group includes 4 members)
 Students are responsible for learning not only the key information of their own
group, but also the information presented by other groups.
 Available biomes – Listed on project description sheet (no two groups may research
the same biome in one class period)
 Timeline of project – Have students fill in appropriate calendar dates and deadlines
in the blanks provided.
 Evaluation of project - Stress that both individual and group grades will be assessed.
Part of your individual grade also includes in-class participation.
5. (Time = 5 minutes) Have students discuss and delegate roles of group members. They
should list all their group members and their assigned roles on their project description
sheet. Encourage students to exchange contact information – phone numbers or email
address – so they can communicate outside of class. Finally, students need to rank the
biomes in the order in which they wish to research them (first choice, second choice… last
choice).
6. (Time = 10 minutes) Allow one student from each group to randomly select a number out of a
container. The total numbers in the container should be equal to the number of groups. The
group that has drawn #1 will get to choose their biome first. All other groups need to pay
attention as they will need to cross off the biomes that have already been selected. The
group that has drawn #2 will get to choose their biome second. Continue as described until
each group has selected a biome to research.
SUMMARY:
(Time = 5 minutes) Review the timeline and important dates of the project with the class. Give the
students instructions on where to report for the next class session (i.e. library, computer lab, etc).
Probe students for recollection of key concepts taught previously: biosphere, biome, abiotic
factors, biotic factors, competition, predation, symbiosis.
LESSON PLAN – DAYS TWO, THREE, AND FOUR
LESSON OBJECTIVES:
1. Students will use the Internet to research answers to the driving questions posed in the
biome project guidelines.
2. Students will use other references as needed (dictionary, encyclopedia, atlas, etc).
3. Students will compile notes and the appropriate bibliography information about each
resource the use for their project.
4. Students will collaborate and pool their research so that every member of the group may
benefit.
5. Students will complete rough drafts of their individual portions in class.
6. Students will work to complete their final project in class as time allows.
MATERIALS:
 Computers with Internet access – for individual and group research in class
 Additional reference materials – such as a dictionary, encyclopedia, atlas,
magazines/journals
 Other student provided materials – students must bring with them to class any additional
materials they will need to complete their project – such as glue, scissors, poster board,
pictures
 Student participation record sheet – on the reverse side of each students evaluation rubric
 Participation observation sheet (for instructor) – for the instructor to use to make notes
about student productivity and assign a daily participation grade.
PROCEDURE:
1. The following procedure is designed to be completed in three 50 minute class periods.
2. (Time = 5 minutes) Review with students appropriate computer usage and on-task behavior.
Emphasize to students the need to record all research and individual accomplishments for
each class period. These records will be used in two ways: (1) to pool individual research
done and share important information with the group; (2) to show participation and on-task
behavior to the instructor at the conclusion of each class period.
3. (Time = 40 minutes) Students should be on-task and productive throughout the entire class
period. Examples of appropriate behaviors include computer research, group collaboration,
typing field guides or presentation outlines, printing or drawing pictures for use on posters
or dioramas, constructing posters or dioramas. Examples of inappropriate behaviors – which
will result in a lowered daily participation grade – include: talking about topics not related to
the project at hand, surfing unrelated websites on the computer, working on assignments
for other classes, lack of participation (zoning out or sleeping).
4. At the conclusion of each period, remind each student to fill out their participation record
sheet (on the reverse side of their evaluation rubric). These papers should be signed and
handed into the instructor before leaving the class for the day.
5. (Time = 5 minutes) Instruct students to begin cleaning up their work area, recycling and
unneeded materials, and checking the floor for trash. The area in which they were working
should be left exactly as it was found. Also instruct students to log off their computers if
necessary and remain seated until the class is dismissed.
EVALUATION:
(Time = entire class period) Throughout the period the instructor needs to monitor each
individual student for appropriate behavior. During the last 10 minutes of the class, circulate
the room and request to see the accomplishments (collecting signed record sheets) of each
student for that class period compared to the start of that day. Record observations on the
participation sheet and assign a daily participation grade for each student at this time. This
will also be an important resource for reference when assigning project grades and if the
students and/or parents question their participation grade.
LESSON PLAN – DAYS FIVE AND SIX
UNIT OUTCOMES:
1. Students will identify the major terrestrial biomes and describe the main characteristics of
each.
2. Students will give examples of plant and animal adaptations to climate.
LESSON OBJECTIVES:
1. Students will listen attentively during group presentations.
2. Students will actively take notes during group presentations.

appropriate behavior during presentations.
2. (Time = 10 minutes per group) The speaker of each group will present his/her biome to the
class. The presentation should be a minimum of 5 minutes and a maximum of 10 minutes.
The guidelines for evaluating the speaker are provided on the speaker’s evaluation rubric.
SUMMARY:
Allow two to three minutes at the conclusion of each presentation for student questions and
clarifications. As the teacher, it is important that you ask questions to test the speaker for their
comprehension of the biome, as well as to stimulate discussion of key information that may not
have been covered.

NATIONAL PARKS TRAVEL ITINERARY
Directions: Imagine you are planning a trip across United States to visit a variety of National
Parks. You’re goal is to visit at least one National Park in each of the possible biomes located in the
USA (including Alaska and Hawaii). In addition, you should try to select the most efficient route
which will have the least amount of backtracking or overlapping.
Mapping: You will need to map out your route on the map provided and color in the major regions
where the biomes occur in the continental United States. Be sure to provide a key to help
interpret your map.
Driving Questions: Be sure to answer IN DETAIL each of the following questions for each biome
you encounter on your journey.
 Which types of biomes are each of the US National Parks in?
 How has the soil and climate determined what vegetation can survive in each biome?
 What special challenges does each biome present for its inhabitants?
 How have the plants adapted to surviving in this climate?
 How have the animals adapted to surviving in this climate?
 What predator/prey relationships or symbiotic relationships exist?
Other Helpful Hints:
 Analyze the route of your travel through the United States. Identify which biome is
most likely present in each of the National Parks that you encounter during your
expedition.
 If there is a biome that is not represented in your journey (there may be several), leave
that section blank.
 Be sure to provide accurate explanations of the environment and unique organisms you
encounter in each biome, as well as how those organisms have adapted to survive.
 Be sure to organize your answers neatly in each of the spaces provided for each biome.
 All members of your group must participate in this activity to receive full credit.
