8. Problem:
Does the amount of dominoes effect its over all
speed and acceleration?
Hypothesis:
I believe that the more dominoes, the greater
the speed. I think this because the more
dominoes, the more force, and with more force,
the faster the dominoes will travel.

15. Problem:
Does the surface of the ramp effect the speed
of the ball and how fast it falls?
Hypothesis:
I think that the surface will change the speed of the
ball, because different surfaces cause a different
amount of friction. I think that the trash bag-covered
ramp will have the fastest time. I think this because the
trash bag isn't clinging, like the smooth surface, and it
isn't ruff like the towel. I predict that the towel will have
the slowest time because of its ridges and its ruff
texture. I also think that the faster the ball rolls down
the ramp, the faster gravity will pull it to the ground.

23. 
I conclude that the trash bag had the best times of: 0.9, 0.9, 0.8, with an average of 0.86. The ball traveled down the
trash bag ramp at a speed of 39.5 cm per second. The towel came in second with 1.0, 1.0, and 1.0 and an average of
1.0.The Towels average speed was 34.0 cm per second. Smooth had the slowest times such as, 1.0, 1.0, and 1.3,
with an average of 1.1. The ball traveled down the smooth ramp at a speed of 30.9 cm per second. The results turned
out this way because of friction. My hypothesis was partially correct, I predicted that the trash bag would have the best
times, which it did, and that the towel would be the slowest, that part was incorrect because the smooth surface was
slower than the towel. During this experiment we also timed how long it took for ball to touch the ground, so in other
words we timed the speed of gravity on the ball. I thought that the faster the ball rolled down the ramp, the faster
gravity would work. But during this test gravity pulled the ball to the ground at the exact same time every time. After
doing reasurch I found that the mass of an object should not effect the speed that gravity pulls the object to the
ground. So Makenzie and I decided to test this again, with a longer ramp we thought that with a longer ramp friction
would have more time to "kick in". We tested with a ramp that was 1 meter and 13 cm long. The 3 surfaces that we
used were: trash bag, towel, and the boards regular surface. The speed of gravity worked at 565 cm per second on
the trash bag surface, 594 cm per second on the towel, and 403 cm per second. So the trash bag was not the fastest
like in the original lab but gravity worked the fastest on the towel, then the trash bag, then the regular surface. The
more friction the slower gravity will work the towel had the least friction in this test and then the trash bag and the
regular surface had the most friction. This lab meet proficiency 3. This meets proficiency 3 because we show the
comparison between the force of gravity on the ball and how friction effected the speed of the ball. Then we found the
acceleration by timing the ball down the new ramp. The acceleration rates were: 477.7 for the trash bag,470.6 for the
towel and 269.5 for the smooth.

24. Proficiency 1
Third Law

25. Problem:
Does the Direction that you hold the balloon in
effect the strength of the opposite force.
Hypothesis:
I that when you hold the balloon with the opening
down the airs force will be the strongest, I think
this because hot air rises and the hot air will travel
into the balloon and push it up for the longest
amount of time.

27. 1. Blow up balloon number

2. Pinch the balloon to
keep the air inside
3. Hold balloon with

10. Repeat step 7
11. Hold balloon facing left
12. Repeat step 6
13. Blow up balloon
14. Hold it to the right'
15. Repeat 3 more times

28. Trial 1 Trial 2 Trial 3 Trial 4 Average
up 1.6 0.9 1.0 0.9 1.1
down 1.5 1.3 0.9 0.8 1.2
Left 1.2 1.6 0.8 0.8 1.1
right 1.3 0.8 1.6 0.8 1.1

30. After testing the equal and opposite force on
the balloon, I found that when the balloons opening is facing
down, that’s were strongest the opposite force is. That proves
that my hypothesis was correct. In my hypothesis I stated that
I believed the force would be strongest with the opening down
Because hot air rises. The hot flows up into the opening, which
is facing down. We timed how long each balloon was in thee air.
With the opening up the average was 1.1, down 1.2, left 1.1,
and right 1.1.This not only shows that the force Is strongest
when the opening is down but that the force is equal from all
Directions, except down. This lab met proficiency number 1,
used this lab to show Newton’s third law. This lab shows
Newton’s third law because, the third law states “ for every
force there is one equal and opposite. The forces are, the
balloon and the air holding up the balloon.

32. Fling a rubber band at dominoes.
When you fling the rubber band, that causes
Elastic potential energy . Elastic potential
energy is

33. Rubber band hits the first domino in the
domino chain.

34. The domino chain falls. Energy pushes through
all of the dominoes causing kinetic energy.
The domino chain shows kinetic energy
Because__. The domino chain also shows
sound energy because the vibrations move
through the domino chain. When the vibrations
move through the domino chain you can even
hear the vibrations and sound.

35. Domino chain hits the marble.

36. The marble rolls of the table. When the marble
roll off the table it falls to the floor. This is an
example of gravitational energy.

37. The marble hit the second domino chain. The
energy from the domino falling, creates
enough energy and movement for the marble
to hit another domino chain.

38. The second domino chain falls. The domino
chain is another example of kinetic energy. The
last domino falls and rings a bell!

40. Bright is the sun. Heat pours out on you.
Sweat drips down your forehead. The heat
bubbles and boils. Why can’t we use the sun for
a good propose? Solar energy allows us to use
the suns natural heat and light to heat and light
buildings. From cooking food to providing energy
for your house, solar energy won’t let you down!
So when your looking for an alternative form of
energy; choose solar because it’s good for the
environment, can save you money, and it has
many purposes.

41. Choose solar energy because it is one of the few
forms of energy that is good for the environment. Unlike
most forms of energy, solar energy doesn’t pollute when
be converted into energy. The sun will give off light and
heat everyday weather we use it or not, so why not use
it? Every 8 minutes the sun gives off more energy than
the whole world uses in a year. In 2 seconds the sun
gives us enough energy to power one million cars! Why
don’t we accept the power and energy that is natural and
clean? We can see energy that is always there! The
United States needs an alternative form of energy and
the most practical is solar. Not only is it good for the
environment but it will save you money too.

42. Collect some rays and money at the same
time! When you get solar energy you can save
lots of money. Depending on your climate and
the amount of panels you own, you can save
anywhere form $30 to $75 monthly. That’s
anywhere from $360 to $900 in a year! The more
panels that you own the more you save. Make
sure to angle your panels for the most sunlight
possible and you will save even more! It’s the
best energy; its saving you money and its good
for many things!

43. Get solar energy for many different things.
Solar energy can do everything for you! It can be
used in the food industry to dry fruit and more.
Naturally hot, the suns energy can be used to
heat houses and pools. Energy from the sun can
be used to give your house electricity. While solar
energy can be used for many purposes it has a
downside.

44. The most common reason keeping people
from switching to solar energy is the coast. To
install solar panels is quite costly and it may take
years before you actually see the savings. After
about 10 years you will start to see savings of
$30 to $75 monthly. Don’t let the initial coast
keep you from converting.

45. Choose solar energy as your alterative form of
energy. Solar energy is good for the environment,
saves you money, and is useful for many things.
Once again GO SOLAR! Saving the earth; one
panel and person at a time.
