In this presentation you will learn how chickadees fly, what Bernoulli's Principle is, and what the four forces of flight!
Air
hits
the
surface
of
the
wing,
which
causes
air
to
flow
underneath
and
above
the
wing.
The
air
on
the
top
of
the
wing
goes
faster
then
the
air
underneath
the
wing.
If
there
is
fast
moving
air,
then
there
is
low
pressure
and
if
there
is
slow
moving
air,
there
is
high
pressure.
This
also
creates
lift.

is

the

force

that

goes

forward.

A
chickadee
gets
thrust
by
flapping
it's
wings.
They also
have
wishbone
shaped
bones.
These
bones
help
them
bend
their
wings
making
it
easier
to
flap
their
wings
.
A
chickadee
gets
thrust
by
flapping
it's
wings.
A chickadee must have
big and powerful chest
muscles to fly. Without
them, they're wings will get
very tired.
A
chickadee's
body
is
streamlined.
If
too
many
parts
of
its
body
is
sticking
out,
it'll
slow
the
chickadee
down.
Streamlining
lets
a
chickadee
go
faster
in
the
air.
...is the force
that goes down.
A
chickadee
weigh
about
11g.
Their
mass
is
kept
low
because
they
have
hallow
bones.
...is

the force

that slows

down.
They chang
e the angle of their

wings and tail to create drag.

This slows them do
wn and helps them turn a
nd land.

Chickadees
are
amazing
flying
birds
and
use
their
wings
for
a
lot
of
things.
Even
though
they're
small,
they
can
flap
their
wings
really
fast.
Daniel Berno

bernoulli's p
rinciple. H

Groningen, i
n the Neth
erlands on
February 8,

1700.
this helps birds move forwards trust has to be greater than drag
if there was no lift the birds or airplane would descend to the ground
