1.
What question did our class want to investigate with our Drake-copter experiment?
a)
What happens to fall time if we increase the mass?
b)
What happens to the direction Drake spins if we increase the mass?
c)
What happens to fall time if we change the shape of the propellers?
d)
Why does the drake-copter spin?
2.
Which of the following is a qualitative observation about the Drake-copter?
a)
The Drake-copter is approximately 20 centimeters tall.
b)
The Drake-copter spins 56 times before it hits the ground.
c)
The Drake-copter has a metal paper clip attached to it.
d)
The Drake-copter has two pink post-it propellers on it.
3.
Which of the following is a possible dependent variable in our Drake-copter experiment?
a)
The time it takes the Drake-copter to fall.
b)
The number of post-it rotors (wings) the Drake-copter has.
c)
The height that you drop the Drake-copter from.
d)
The angle of the rotors (wings) on the Drake-copter.
4.
What is the Independent variable we chose to investigate in our Drake-copter experiment?
a)
The number of paper clips attached to the Drake-copter.
b)
The number of post-it note wings we attached to the Drake copter.
c)
The amout of time it took for the drake copter to fall.
d)
The shape of the Drake-copter wings.
5.
Which of the following is the hypothesis for the Drake-copter experiment?
a)
I think that if we increase the mass of the Drake-copter, then the fall time will decrease because gravity will pull a heavier object faster.
b)
I think that if we change the mass of the Drake-copter then the fall time will change.
c)
What will happen to the Drake-copter if the mass increases?
d)
How many paper clips does it take to make the Drake-copter fall faster?
6.
Why did we use a line graph instead of a bar graph when analyzing our data?
a)
We use a line graph when we want to compare categories.
b)
We use a line graph when we want to compare percentages.
c)
We use a line graph when we use sequential/ continuous numbers.
d)
We always use a line graph when we plot anything about Drake.
7.
If my hypothesis is not supported by my experiment, then that means my experiment was a failure.
a)
True
b)
False
8.
What would NOT be a good reason to write clear, specific and accurate procedures in a lab report?
a)
So that other scientists can repeat the experiment exactly as you did it to verify your findings.
b)
So that other scientists can steal your work.
c)
So that you can check to see if you had any errors in your procedure.
d)
So that you can reflect on how you could improve the accuracy of your experiment and reduce errors.
