1
Why is asking a really good question a part of the scientific method?
The question guides your research.
Without a question you don't need a hypothesis.
All of the above are correct.
You won't learn anything new if you don't ask questions!
2
Which of the following is the right order for the scientific method?
Observe, Question, Research,Hypothesize, Experiment
Question, Research,Hypothesize, Experiment, Analyze
Observe, Question, Research,Hypothesize, Experiment, Analyze
Observe, Question, Hypothesize, Research,Experiment, Analyze
3
The F in SELFIES stands for
formulate a question
find books and articles to research
formulate a hypothesis
find the answer
4
Which of the following is not an observation?
The wad of paper travels faster than the sheet of paper.
All of the above are observations.
The paper airplane stays in the air for three seconds.
The airplane will fly higher because it has elevators.
5
Airplane wings help lift the entire plane because they allow air molecules to
accumulate
pass over the top of the wing
pass under the bottom of the wing
pass more quickly over the top than the bottom of the wing
6
True or False? The scientific method starts with a hypothesis.
False
True
7
#3: Nina is researching aerodynamics. She will be reading about all of the following except
Cars
Planes
Rockets
none of the above
8
Ava throws a sheet of paper forward. Why does it end up behind her?
Lift
Weight
Drag
Thrust
9
What is the acronym that helps us remember the scientific method?
The experiment form that I fill out
Observe, Question, Topic, Hypothesis, Data, Share
SELFIES
Hypothesis
10
Challenge Round #1: Emily's plane goes slower the harder she throws it. What is the problem?
There is too much weight.
There is too much drag.
Emily's plane has too much thrust.
Emily needs to chill out.
11
Challenge Round #2: Which force of flight does this picture help us understand?
Weight
Lift
Thrust
Drag
12
Which of the following is not included in the scientific method?
Asking a question
Researching the topic before formulating the hypothesis
Sharing the results of your experiments
All of these are a part of the scientific method.
13
Which of the following forces of flight can be produced by jet engines?
Weight
Lift
Drag
Thrust
14
If the question is "How can we make a better airplane?" Which is the best hypothesis?
Elevators and fins will make the plane go farther.
The plane will stay in the air longer if it has large wings.
Elevators will make the plane stay in the air longer.
If the plane has a fin on the back it will fly farther.
15
During the experiment you should
label each plane and keep track of each one.
Record the distance and time of each flight.
All of the above should be done.
Make sure that there is only one variable.
16
What should you be doing during an experiment?
asking questions
collecting data
you must record the whole experiment using a camera
being quiet
17
Which of the following is the best question to guide our experiment?
How high can a plane fly if it never runs out of fuel?
How do the four forces of flight help a plane fly?
How can we make a better paper airplane?
How do paper airplanes fly?
18
What should you do once you are done with the experiment?
Take pictures of everything
Do research
Analyze the data
Ask another question
19
This force of flight wants things to stop moving forward:
thrust
lift
drag
weight
20
Julian wants to know how to make a better airplane. Which one is his best hypothesis?
Larger wings will create more lift.
Elevators on the back of the plane will create more lift.
Both are hypotheses and they both work just fine.
Neither are hypotheses.
21
A "variable" is something that can be different. How many variables should an experiment have?
Two
One
Three
None
22
Aerodynamics is
how states of matter move around things
All of the above are correct.
how gases move through the atmosphere
how air moves around things
23
How can Julian conduct his experiment if he thinks that elevators will create more lift?
Make one plane with elevators. Collect data on that plane.
Compare every plane that has elevators.
Compare 2 identical planes except 1 plane has elevators.
All of the above are wrong!
24
The four forces of flight are
Thrust, drag, lift, weight
Thrust, drag, lift, and gravity
Air, balance, motion, drag
None of the above
25
Which of the following is the best question for our paper airplane experiment?
Why do airplanes move?
What are the four forces of flight and how do they work?
How can we make an airplane that flies farther?
How can we make more thrust?
26
Air is mainly made up of
water vapor
carbon dioxide
nitrogen
oxygen
