the great plant escape (http://urbaext.illinois.edu/gpe)
if we plant a seed in newspaper,soil,sand,and gravel we are trying
to ﬁned out wich of them are best to plant seed in. the textur of
the stuﬀ make it esyer or harder for the plant to grow. the cakes
grows better in sand than in graval. the sand is smooth and graval
Do you think that plant can only growin
in dirt? we put a cup of soil, sand, graval,
and newspaper in four diﬀrent cupes.
nex we put on seed in all four difrent
cups and we added water to all fore cups.
then we put the cupes by the wind-do so
thay can get sun light. Finaly we let the
plant sit in the cups by the wind-do for
If we plant a seed in a cup ﬁled with soil
and has energy and sun light it will
germinat because the seed uses the sun
light and energy and the nutrients from
the soil for food so the plant can
germinate better than graval ,sand and

seed to germination
To test our hypothesis we put fore been
seed in fore difrent cups. The cups are
newspaper, graval, soil, and sand. We
where trying to ﬁnd out wich one of the
cups are better to plant seed in. We let
the seed have sun light energy and water
to seed wich one it germinates better in.
The ﬁrst picher is when we ﬁst
planted it. The second piher is data the ﬁst
latter on when the cot stating to
brack. The threed one is when
the roots are stating to sprout.
the fourth one is when the seed
has all most sprouted all the way.
secon picher is
threed one is
sand and the
four is soil.
here som picher of our
I planted a been seed in three diﬀerent
cups of soil and one cup of newspaper . In
the experament I found out that soil
grows better because the soil had the
nutrients for the plant to grow faster. For
exampal the soil was the frist one to grow
then it was the sand then the newspaper
then the last one was graval. Becaus the
graval, sand, newspaper dident have the
right nutrients for the plant.
