The passage below describes some of the steps of the scientific method. Select the part of the
passage that describes developing the
hypothesis.
bubbles
Brittany was a deejay who used a bubble machine at her events. She wanted to know
how to make the bubbles last longer. She read in a book that bubbles burst because
the liquid that makes up the bubbles evaporates. She knew that warm liquids evaporate
faster than cold liquids. So, Brittany expected that the temperature of the bubble
solution could affect how long the bubbles lasted, with colder bubbles lasting longer.
Brittany heated six bottles of bubble solution to 110°F, kept six bottles at 75°F, and
cooled six bottles to 40°F, and then she measured how long bubbles from each of the
bottles lasted. Because the bubbles from the colder solution lasted longer than bubbles
from the other solutions, Brittany reasoned that temperature does affect bubble
lifespan. For her next deejay event, she iced the bubble solution before she loaded it
into the bubble machine.
