Answer: Sara tries turning a test tube upside down to collect a gas.
A scientist is considered to be creative when he approaches a problem with new different ways. The conventional way is to design an experiment and take detailed notes, reading referenced studies previously done. Sara tries turning a test tube upside down to collect a gas is a creative way as Sara tries something different.
The best answer I believe Sara. By letting the test tube sit upright she is not collecting anything as gas vapors rise. By thinking outside of the box and turning it upside down she can then collect the gas in the test tube.
