1. Determining the problem or question.
My
house has been
invaded by mice.
I had
already saw 2 mouses
in the
kitchen. I had
been searching and the
easiest method to
eliminate this animal
is
bying
a
mousetrap.In those instruments i should put some cheese,and my problem is….What type of cheese i should put to trap all mice in the shortest time?

2.Development of a
hypothesis
The
favourite
food of mice is cheese,so
i decided to try different
type of cheese (
explain in
step nº3). I think that
all mice
will go to eat
the cheese
which
its
odour is stronger ,because it will attrack their attention.So in this case the matured cheese.Paula Berlanga García Modern Science 20145Slide5
3. Design an experiment to test the hypothesis
I
decided
to use three
types of cheese to attrack the
mice attenction:
1.Matured cheese (queso curado
)2.Semi-matured cheese (
queso semicurado)3.Blue cheese
I will put
the
mousetrap in the
same
place
in
my kitchen,the same time with each type of cheese (2days-48hours).In this experiment my experimental variable will be the 3 types of cheese, and
my control variable the
mousetrap without
cheese

5. Draw Conclusions from your data.
Tasting
the
blue cheese, 1 mouse was eliminated,
with the cheese
curds 4, with
ripenese
cheese 3 and without any
type 0 mice (
they dont even
get closer
the
mousetrap
because there wasn´t food) So my hypothesis was wrong,looking to my data mice would go to the cheese wichs odour is soft, because
the smell
is not so
strong so
they doesn´t
get
scary
