T.Ben wants to test if special shoes will make him run faster. What is the control group?
Running with the special shoes on
Running in his normal shoes
Where he runs
How often he runs
2
Why do cans keep their shape when they are empty?
They are made of metal and are strong
Nothing is pushing against the can
Air inside the can pushes against the air outside the can
Because of their shape
3
Why do hot air balloons fly?
Because we use helium to fill it up
Because the wind blows into the balloon and fills it
The hot air balloon is lighter than air
We heat up air so it rises into the balloon

11
What does "dependant variable" mean?
The things we can change in the test
The thing that gives us the end outcome
A guess we make before doing the test
The points, score or outcome of the test
12

15
What is the definition of "experiment" in the scientific method?
Making a lot of guesses to test
Something we make so we can try and answer a question
Trying something new for the first time
Asking a question
16
How do we turn steam into water?
You can't
Heat it up
With nanotechnology
Cool it down
17
What happens to air when it gets hot?
It turns to steam
It rises (goes up)
It falls (goes down)
Nothing
18
In the air pressure experiment with the can, what is in the can when it gets crushed?
Steam
Air
Nothing
Water

25
Testing if you can run faster in special shoes. Which of these is the dependent variable?
How often you run
The type of shoe
Where you run the race
