Title: Comparing and Contrasting Plant Structures
Sunshine State Standard Benchmark SC.F.1.3.4: The student knows that
the levels of structural organization for function in living things include
cells, tissues, organs, systems, and organisms.
Grade Level Expectations: Sixth Grade. The student knows that the levels
of structural organization in living things include cells, tissues, organs,
systems, and organisms.
Write the objective:
Given live examples of five types of plants, the student will correctly
compare and contrast physical characteristics of five of six plant structures
(roots, stems, leaves, flowers, fruits, and seeds).
Introduce the lesson:
- Gain student attention – The class takes a brief
walking tour of
the school grounds and observes the types of plants. They make notes and
sketches of what they see. Upon returning to class, students compile a
list of what they saw. The teacher points out the physical characteristics
of the plants that are the same and those that are different.
- Explain the objective – The teacher tells the students that they
should be able to look at five different plants and compare and contrast
the physical characteristics of each of the plant structures (roots, stems,
leaves, flowers, fruits, and seeds).
- Related to prior knowledge – The teacher reminds students what
they have already learned about plant structures and how the environment
impacts plant growth. The teacher also reminds students what it means
to compare and contrast and how to use good observation skills.
Present the content:
Knowledge and skills in lesson – Students have basic information
on plants and what it takes for them to grow. They have information on
basic plant structures. The lesson content will focus on information on
physical characteristics of plant structures.
Teacher and student learning activities
- The teacher presents a mini-lecture on the physical characteristics
of plant structures. The lecture is accompanied by video or internet
examples that define and illustrate characteristics of plant structures
(roots, stems, leaves, flowers, fruits, and seeds).
- The teacher also links the information to previous lessons in the mini-lecture.
The examples include pictures of each type of plant structure. Students
will take notes during the lecture using a note-taking
guide. See sample Note-Taking
Guide
- Next, the teacher models how to make observations of a sample plant
and records her observations on a transparency of a worksheet to compare
and contrast of plant structures. See sample Worksheet Transparency. The teacher demonstrates the process
to compare and contrast the physical characteristics she has observed.

Activity organization and support
- Media selection: Prepare a note-taking guide to provide
scaffolding for
students in the mini-lecture. Prepare a compare and contrast worksheet
to guide and record the observations of the plant samples in the second
part of the lesson. Make three copies per student. Make a transparency
of this worksheet. Obtain sufficient plant samples.
- Student grouping: The mini-lecture is a whole class activity using an
internet link or video. The second part of the lesson is a small group
activity.
Practice and feedback:
- Guided practice – The teacher divides the class into groups
of four, giving each group two actual plant samples and copies of the
worksheet to use as a graphic
organizer to compare and contrast plant structures.
The students work in groups to complete the worksheet. Students are
encouraged to follow the note-taking guide and projected transparency to structure
their responses. The teacher
observes groups and provides feedback while students are completing
the worksheet. The teacher is prepared to add more plant samples to
the activity if students need additional
time and practice. She debriefs the activity with the whole class.
- Independent practice – Independent practice will be a homework
assignment. Using a second copy of the practice
worksheet, the students
identify five plants growing at their home or neighborhood, record
characteristics of plant structures, and compare and contrast the plants. The teacher reviews the worksheets completed for homework and provides
feedback to students. She arranges for an individual or small group
discussion with students who may need additional
practice.
- Judicious review – The teacher reviews physical characteristics
of plant structures in at least one additional lesson within the unit
on plants. She surveys units for the remainder of the course and notes
places to incorporate reviews of these skills.
Summarize the lesson:
The teacher writes the lesson objective on the
board and reads it to the class as a summary of what students are supposed
to learn. She asks students to recall parts of the mini-lecture and group
work that helped them learn this knowledge.
Assess student learning:
- Determine the procedures – The teacher will use a performance
assessment to measure student learning by setting up five stations
with real plants (different from those used in guided practice) at
each station. The students are divided into five groups to move through
the stations. The teacher tells students they are to independently
observe the plants at each station and use the compare and contrast
worksheet to write observations of the physical characteristics of
each plant structure. Then they should return to their desks to complete
the comparison and contrast of the physical characteristics of the
structures of plants. She tells students they can revisit stations
as needed. The teacher reminds students that they will need to correctly
compare and contrast at least five of the plant structures in order
to master the objective. Students complete this activity independently.
The teacher cautions students not to copy notes from one another as
they move through the stations.
- Decide how to judge performance – This is a performance assessment
that includes conducting observations and writing a description. The
teacher designs an evaluation checklist that lists the points expected
in the comparison and contrast for the comparison of all the plants.
The teacher reviews each student paper and completes the evaluation
checklist. She makes additional comments, if needed. The papers and
the completed checklist are returned to students as feedback on the
assessment. The teacher gives individual
feedback to students who did not meet the mastery criterion
and discusses plans for helping them meet it.
Accommodations
- Present the content, Guided practice, and Independent practice
For students in the class who typically need assistance in organizing
their responses to complex tasks, the compare and contrast worksheet
form used for all students in the practice and assessment activity will
be used for these students.
- Assess student learning
For a student who is easily distracted while completing written assignments,
the teacher will allow the student to complete the written contrast
and comparison required in the assessment using a study carrel turned
away from the students who may be moving around the stations with the
plant samples.
