Note: Newton's second law states that the net force acting upon an object
is equal to the rate at which its momentum changes with time. If the
mass of the object is constant, this law implies that the acceleration
of an object is directly proportional to the net force acting on the
object.
Translated Note: If an object’s mass does not change,
but it’s height does, I can make it go faster/further
which will show more energy/outcome.
An
educated scientific guess
that I can test.
1) Plan out my Experiment
2) Gather up and list your materials: Be Specific
3) Write a PROCEDURE. A procedure is a list of steps that you did to
perform an experiment. Scientists do this so that people will
believe that they did the experiment and also to let other people
test what they found out.
4) Identify your variables. The variables are any factors that can change in an
experiment. Remember that your experiment should only test one variable in
order to get accurate results.
controlled variables: same type of dirt, same marble, same cola, same amount salt, etc.
independent variable: what is being changed to be tested? different brands, more water,
less sunlight, higher elevation, different mass, etc.
dependent or responding variables:. What happens as a result of your test?
5) Set it up And

Write a Conclusion: Tell us what happened.
◦ Was your hypothesis right or wrong or neither?
◦ Were you successful; did it turn out okay?
◦ Would you change anything about the experiment or are you
curious about something else now that you’ve completed your
experiment.
◦ And most of all, TELL WHAT YOU LEARNED FROM
DOING THIS.
Conclusion:
I changed the height of my ramp to 5 different heights. Each
time I put the same aggie marble at the top. I created a learning start,
so that I wouldn’t shove it, to where I lifted a piece of paper it rolled
down the ramp. I let it roll to a stop and put tape there and measure.
Then I recorded the measurements in my data journal.
I raised my ramp to the next level height, since the height was
my independent variable, and used the same aggie marble and did the
same process. I repeated this experiment with 5 different heights.
From my data I conclude that my hypothesis is correct: I did
prove that height does increase outcome of energy because each
increase in height resulted in increased distance.
