Breedlove Science 8 Lesson Plans, Sept 26-30
Monday
Standard
GLE 0807.5.4 Explain why variation
within a population can enhance the
chances for group survival.
I can identify variations in a species.
I can explain how natural selection
works.
Students respond to the following
prompt- “Look around the room.
Notice the differences or variations
in our species. Now make a list of at
least 10 of the differences you
notice.”
1. Students watch a short video clip
to introduce Darwin and finches.
2. Students analyze chart with finch
phylogeny.
3. Students research how variation
occurs by reading text pg. 45.
4. Students answer questions about
variation in a population of
finches.
5. Students analyze text about
variation in potato crops and
disease resistance.
Students watch the BrainPop video
“Natural Selection.”
Students complete graphic
organizer with environmental
pressures and variations.
Students complete p. 64 in which
they summarize learning by
explaining, listing, applying, and
identifying concepts from lesson.

Tuesday
GLE 0807.5.4 Explain why variation
within a population can enhance the
chances for group survival.
1. Students read text pg. 43.
2. Students discuss the principles of
natural selection and give
examples.
3. Students view examples of
natural selection. (The camel on
page 40, the horse in the
flipchart, and the video about
elephant evolution)
4. Students further natural selection
and genetic bottlenecks.
Wednesday
Standard: SPI 0807.5.2 Analyze
structural, behavioral, and
physiological adaptations to predict
which populations are likely to survive
in a particular environment
EQ: what are the factors of natural
selection?
Students will begin by answering the
question: what does survival of the
fittest mean to them? How could this
be portrayed in nature
Students will be given the definitions
to adaptations and variations. We will
then discuss how these could lead to
population change in a given
ecosystem
Do adaptations and variations play a
large role in natural selection? Why
or why not?
Friday
GLE 0807.5.4 Explain why variation
within a population can enhance the
chances for group survival.
I can provide evidence that supports
natural selection.
I can explain why variation within a
population can enhance the
chances for group survival.
Students create a word tree by
starting with the word “Train” and
by adding, deleting, or substituting
one letter at a time to form new
words and tree like diagram.
Students answer practice questions
about the importance of variation.
1. Students read Evidence for
Natural Selection.
2. Students read text pgs. 53-55.
3. Students take notes from
flipchart.
1. Students are introduced to
cladograms, or branching trees,
graphic organizers that show
evolutionary relationships
between dinosaurs and birds.
2. Students analyze the arthropod
branching tree and answer 4
questions.
3. Students use a plant branching
diagram to answer 2 questions.
4. Students use the branching
diagram of primates to answer 4
questions.
Students complete the fishbone
graphic organizer on text pg. 59
Students create their own
branching diagram of a frog, snake,
kangaroo, and a rabbit.
Students will then be given the link to
a virtual lab website created by
glencoe. This virtual lab models
natural selection with several
different variables that the students
will have to observe and graph.
Vocabulary: Charles Darwin, variation, natural selection, embryology, homologous structures, vestigial structures
Flex: Students watch “Biomes: Islands and Evolution” and answer discussion questions.
Thursday
GLE 0807.5.4 Explain why variation
within a population can enhance the
chances for group survival.
