  • 1. ObjectivesThe objective was to find out how adaptation helps animals survive. We had to find out what type ofbeak would be better for a birds survival.HypothesisI hypothesize that the bird with the spork beak will get most of the seads. The bird with the fork will getthe least and the bird with the spoon will do fairly well.Materials Spoon Fork Spork White beans Brown beans PeasMethodA.
Students
will
be
placed
in
groups
of
31.

“The
Bird”a.

Will
be
given
a
60
second
interval
to
gather
as
many
insects
as
possible.b.

The
bird
will
only
use
its
beak
to
capture
insects.c.

The
bird
will
NOT
use
its
feet
(hands)
to
help
pick‐up
or
transport
insects.d.

When
the
beak
is
full
of
insects
the
bird
will
fly
back
to
the
nest,
deposit
the
insects,
then
proceed
to
gather
more
insects.2.

“The
Nest”a.

The
nest
does
NOT
move.b.

The
nest
holds
the
insects
the
bird
has
gathered.3.

“The
Counter”a.

The
counter
will
help
separate
and
count
the
insects
gathered.
b.

The
counter
will
write
down
totals
for
data.c.

The
counter
will
bring
the
teacher
all
insects
gathered.B.

Groups
of
birds
will
be
assigned
nesting
locations
around
insect
dense
grasslands.C.

After
each
gathering,
students
will
change
their
role
in
the
group.

There
will
be
3
gathering
periods
so
every
student
will
have
a
chance
to
be
“the
bird”.Analysis (you
will
build
a
bar
graph
also,
teacher
will
explain) 1. What
environmental
factors
determined
how
many bugs
were
captured
by
each
group?If they live in an enviorment with not many bugs they wont catch as many as if they live in a bug infestedinviorment. 2. Give
two
types
of
evidence
for
evolution.Scientist have found some bones in fish that show that they used to walk on land, therefore theyevolved. 3. How
does
genetics
fit
into
evolution?Evolution occurs because the genes go through a mutation. 4. Include
five
new
words
and
their
definitions
that
you
learned
during
this
evolution
unit.
  • 2. Conclusion 1. Who
was
Charles
Darwin?Charles Darwin was a naturalist who first introduced natural selection. 2. Why
is
Darwin
so
important
to
biology?Darwin contributed and was importance to science because he suggested that we all change in order tosurvive better. 3. Why
are
animals
(organisms)
so
different?Organisms are so different because of evolution and natural selection. 4. Did
the
data
support
or
reject
your
hypotheses?

Explain
for
each
hypothesis.The data proved that I was wrong because the spoon got the most bugs.
