A scientist is testing which ice cream flavor melts the fastest. What would be his controlled variables? (choose ALL that apply)
The flavor of the ice cream
the type of cone the ice creams are in
the location in the room where the ice cream is
the size of the scoop
the time it takes to melt
These are the variables that must remain the same. They do not receive any change to make a fair test.
