Carefully
plot
your
data
on
a
graph
to
show
how
the
relative
percentages
of
Parent
and
Daughter
changed
over
time.
a)
Neatly
mark
an
even
scale
on
the
vertical
y-axis
from
O
(bottom)
to
100
(top).
Label
this
axis
“Percent
(%)
Material”.
Using
100
“objects,”
your
counts
will
plot
directly
as
percentages.
b)
Neatly
mark
an
evenly
distributed
scale
on
the
horizontal
x-axis
from
O
(left)
to
the
number
of
half-lives
(rounds)
needed
to
reach
0%
parent
material
(right
end).
Label
this
axis
“Time”.
c)
Create
a
curve
for
Parent
Material:
Plot
%
of
Parent
Material
on
the
vertical
axis,
vs.
Time
(humber
of
half-lives
or
Rounds)
on
the
horizontal
axis.
Connect
your
data
points
with
a
smooth
curve.
Label
the
curve
“Parent”.
d)
Create
a
separate
curve
for
Daughter
Product:
Plot
the
%
of
cumulative
daughter
(last
column
in
the
table)
on
the
y-axis
vs.
Time
(x-
axis).
Connect
the
data
points
with
a
smooth
curve.
Label
