What makes one rocket perform better than another? (Do
not forget to examine the weight of each rocket. Rockets made with extra
tape and larger fins weigh more.)
How small can the fins be and still stabilize the
rocket?
How many fins does a rocket need to stabilize it?
What would happen if you placed the rocket fins near
the rocket's nose?
What will happen to the rocket if you bend the lower
tips of the fins pinwheel fashion?
Are rocket fins necessary in outer space?
What does it take to create an experiment?
Keep in
mind that you are setting up an experiment. For an experiment to be
successful you must have accurate data. To get accurate data you must
control as many variables as possible. In order to insure that you
have an understanding of what these variables are they are listed below.
Length of body
Weight of body
Shape of nose
Shape of fins
Area of fins
Number of fins
Position of fins
For your experiment to give you accurate results you must control all of
the variables except one. The variable that you change is what you are
experimenting with.
Follow the arrows to build your
rocket.
Launch your rocket three times. How far did it fly
each time? What is the average distance your rocket flew? Write your answer
on the Paper Rockets worksheet.
Build and fly a rocket of a new design. Fly the rocket
three times and average the distances. What is the difference between the
average distance of your first rocket and the average distance of the second
rocket?
Build a third rocket and repeat step 2.
On the back of your worksheet, draw pictures of the
rockets you constructed and show where the center of mass and the center of
pressure are.
