I made all of my cuts precise and made sure all of my folds were the exact same length.

I added more wings/flaps to my helicopter to make it faster

I added more wings/flaps to my helicopter to make it faster

# data[].attributes.body
I increased the length of my propellers and all it did was make it spin 2 times instead of 3 times.

# data[].attributes.body
I wanted to see if shortening the wings would make the helicopter spin more. The wings were originally 2 inches and spun, on average, 4 times before hitting the ground. I changed the wings to 1 inch long. The spin average was 4.5.  The independent variable was the wing length. The dependent variable was how many times the helicopter spun.

# data[].attributes.body
I wanted to see if making the flaps thinner would change how much the helicopter spun. I made two prototypes, and the variable I tested did not seem to have a significant effect on spin rate, as I got the same results over 3 trials.

# data[].attributes.body
I added more weight to the center and now it spins a lot more.

I switched the blades around so the helicopter now spins clockwise.

Before I dropped the helicopter, I spun it. The average seconds it took for the helicopter to reach the ground with no spin was 1.61 seconds. And the average amount of time it took the helicopter to reach the ground after spinning it was 1.53 seconds. The dependent variable was the helicopter with no spin and the independent variable was the helicopter with a spin. In conclusion, the helicopter was able to stay up in the air longer with no spin.

i cut the propellers 4 times each side to see if it would spin faster

For my Independent variable I made the creases stronger by using a giftcard. My dependent variable is I measured the time it took for it to touch the ground. When my helicopter had stronger creases it took longer for it to touch the ground.

# data[].attributes.body
I put tape on the underneath of the flaps and it didn't change anything. They bothecame down at the same time. independant: size of helicopter
dependant: time it took to reach the ground

# data[].attributes.body
My independent variable was the the place I dropped the helicopter. (of the stairway) My dependent variable was putting tape on flap C and D.  I thought if I put tape on flaps C and D, it would stay on the air but it was the complete opposite. I did 3 test and here the data collected from experiment:
Test 1- 3.05 seconds
Test 2- 2.32 seconds
Test 3- 2.73 seconds

# data[].attributes.body
Adding tape to the bottom flaps did not affect how much it spun.

I cut my two flaps into 4 and it spun twice from above my head

For my experiment, I made the helicopter smaller. I did this to test if i changed the size, the speed at which it falls and how quickly it spins would change too. My experiment was a success. Contrary to the large helicopter, the small one spun much faster, but dropped much slower.

# data[].attributes.body
I folded the propellers of my helicopter and made them into tubes, and then It spun 3 times while without the flaps folded it spun 8 times, but it made it flip like 10 times.

# data[].attributes.body
In this experiment, I shortened the length of my helicopters propellers. From a height of (approx.) 20 feet. The default helicopter spun 3 1/2 times, while the shortened-propeller helicopter spun barely 1/2 of a spin. Although I accidentally cut shorter than I would've like to, I had to go with it because making a new helicopter is too inconsistent with my rookie-level craftsmanship. I theorize that the helicopter spun less with it's propellers shortened than not, because there is less mass to catch the fall, rendering it unable to spin as well.

# data[].attributes.body
Using water, I wet the wings of the helicopter. When I did this it fell faster and would no longer spin.

# data[].attributes.body
I used a smalller piece of paper to see if it would affect the speed to the helicopter and it made it go faster.

# data[].attributes.body
I made flaps on the blades of my helicopter

# data[].attributes.body
I switched the way the flaps are faced to see if they would spin counter-clockwise.

# data[].attributes.body
I made my helicopter small to see if that would affect how many times that spun around. My big helicopter spun around 3 times and my small one only spun around twice.

# data[].attributes.body
i added folds onto my helicopters wings, by doing so, my helicopter fell in a straighter line.

# data[].attributes.body
I added a paperclip to the helicopter and approximately the time of dropping to the ground decreased for 1 second.

# data[].attributes.body
I wanted to make my helicopter smaller to see if that would affect the air time. However both helicopter stayed in air for exactly two seconds.

# data[].attributes.body
I made the flaps longer to see if it would spin more

# data[].attributes.body
I added weight to the flaps to see if it would make it fall faster. When I added weight, it did indeed, make the helicopter fall to the ground faster.

# data[].attributes.body
I changed the direction of the helicopters wings so A is now opposite of B. The wings changing their directions did NOT change the direction that the helicopter spun.

# data[].attributes.body
I increased the wing length, but it only increased the flight time to the point. After that, it became a piece of paper that floated down really quick.

# data[].attributes.body
I changed the material of my helicopter to see if it would affect the speed of the fall. I cut out a piece of notebook paper to the size of an index card and made my 1st helicopter out of that. It's fall time was 1.99 seconds. Then I made a second helicopter out of index card material. It's fall time was 1.05 seconds.
