It becomes a law.
It remains the same.
Which evidence best supports a scientific explanation?

One of the following scientists contributed to the modification of atomic theory by showing that electrons orbit an atom’s nucleus and that electron orbits have a particular amount of energy. Which scientist and his work led to the modification of atomic theory?
Joseph Thomson discovered electrons, which he believed did not move.
John Dalton proposed a model of the atom showing it as a solid sphere.
James Chadwick found that, in addition to protons and electrons, atoms also contain neutrons.
Niels Bohr’s research showed that electrons follow specific paths around the nucleus of an atom.
Many scientists study climate theory and ways that Earth’s climate may have changed throughout its history. Researchers in Antarctica study ice samples that are thousands of years old. Which reasoning describes why they would study samples of ancient ice?
They expect to find evidence of earthquakes.
They want to locate traces of ancient human populations.
They are seeking evidence of past atmospheric composition.
They are searching for evidence of the region’s natural resources.
Early scientists wondered how two parents with brown eyes could have a child with blue eyes. Which of these studies would best help scientists investigate how blue eye color is inherited from brown-eyed parents?
study the history of the family eye color of 100 random people
study the history of the family eye color of 50 blue-eyed people
study the history of a family in which all individuals within the past five generations were born with blue eyes
study the history of four generations of 20 different families in which brown-eyed parents had at least one blue-eyed child

galaxies moving farther apart
galaxies moving closer together
galaxies not moving away from or toward each other
galaxies spiraling away and towards each other

hypothesis
observation
variable
Juan, a biologist, notices that a particular group of hummingbirds leaves during the colder winter months and returns during the warmer spring months. Juan hypothesizes that the birds fly south to locations with warmer weather and blooming flowers during the winter months. Which procedure should Juan use to test his hypothesis?
Survey northern and southern residents about the birds ni their areas.
Observe the direction the birds fly when they depart in the winter.
Tag the hummingbirds with transmitters and track their movement.
Set up observation posts in the south to verify the time of year that birds arrive.
Ana is in charge of studying how air quality affects the respiratory health of the citizens in her state.
Which testable claim does she investigate?
The quality of the air varies throughout the state.
Air quality in her state is worse than it is in other states.
Air quality has a relationship to respiratory problems.
Ari quality is worsening due to increasing population and industrialization.
A microbiologist investigates the outbreak of an unknown illness, which is thought to be caused by a new strain of bacteria. Doctors have determined the bacteria are located in the lungs. Initial work on treating the illness is dependent upon analysis of the bacteria. Which investigational method should the microbiologist use to start the process to analyze the bacteria?
Review the patients' medical charts.
Interview people who have become sick.
Review the treatment medications and their effectiveness.
Take samples of the bacteria and grow cultures in a lab setting.
Scientists use many different methods of investigation.
When possible, scientists want to actually experiment or observe an event.
Which method is useful when developing a scientific reasoning for an event that cannot be studied directly?
Conduct a field survey of bird populations in an area
Observe the effect of various fertilizers on corn crop yields.
Use a computer model to study how the ocean liner Titanic sank
Use a wind tunnel to measure air drag on various types of automobiles.
