A timeline of some models of atoms throughout history is shown below. These models have contributed to the formation of the atomic theory.

Which statement best summarizes the development of the atomic theory over time?

• The discovery of new evidence resulted in changes to the atomic theory.

• Advancements in atomic models proved the atomic theory was accurate.

• The atomic theory was modified with the discovery of every new element.

• Changes in atomic models showed that the atomic theory was based on opinion

Scientist Jordan makes a discovery and publishes the results for other scientists to read. Scientist Kesha tries to repeat the experiment and cannot make it work. Her results are also published. Scientist Jordan looks at his data again and finds that the discovery only works under certain conditions. He publishes the change. Now scientist Kesha repeats the new method and finds the same results as Jordan, but another scientist, Winslow, gets different results. What does this story demonstrate?

• Scientific knowledge results from a lot of debate and confirmation.

• Scientific knowledge is developed by individual scientists in isolation.

• Scientists consistently disagree with each other during experimentation.

• Scientists consistently share common interpretations of data and information

Laboratory experiments, observational field studies, and model-building are all examples of different forms of scientific investigations. In what way do laboratory experiments primarily differ from other forms of scientific investigations?

• Laboratory experiments involve the identification and control of variables.

• A laboratory experiment is the only accepted form of investigation within the scientific community.

• Data can only be generated through laboratory experiments, not other forms of investigation.

• Studies about how things behave in nature or studies involving very large objects are best answered through laboratory experiments

Caleb is riding his bicycle. He works very hard to reach the top of a hill and then coasts down the other side.

Which statement best explains what happens as Caleb rides down the hill?

• Chemical energy is transformed into mechanical and thermal energy and the total amount of energy decreases at the bottom of the hill.

• The amount of mechanical energy used to ride the bike uphill is less than the amount of chemical energy used to ride the bike downhill.

• Chemical energy is transformed into mechanical and thermal energy and the total amount of energy is conserved during the entire bike ride.

• The amount of mechanical energy used to ride the bike uphill is greater than the amount of chemical energy used to the ride the bike downhill.

A television is a device that converts electrical energy into light and sound energy. However, this energy transformation is not 100% efficient. What happens to the electrical energy that enters a television but is not converted into light or sound?

• It is transformed into heat energy.

• It is stored in the wires in the television.

• It is destroyed in the transformation process.

• It returns to the electrical socket to create new energy

Observe the illustration of a simple circuit below.

Which of the following statements best describes the energy transformation that takes place in this circuit?

• Electrical to light to thermal energy.

• Thermal to electrical to mechanical to energy.

• Electrical to chemical to mechanical to light (radiant) energy.

• Mechanical to chemical to electrical to light (radiant) energy.

Use the image below to answer the following question.

Which solar property is represented at number nine?

• core

• sunspot

• Solar flare

• prominence

The stars, Rigel and Betelgeuse, are both found in the Orion constellation. Rigel is a blue supergiant, and Betelgeuse is a red supergiant. Which of the following correctly compares the temperatures of Rigel and Betelgeuse?

• Rigel is hotter than Betelgeuse, because blue stars are hotter than red stars.

• Betelgeuse is hotter than Rigel, because red stars are hotter than blue stars.

• Rigel and Betelgeuse are close to the same temperature, because they are both supergiants.

• Betelgeuse and Rigel are close to the same temperature, because they are about the same distance from the Sun.

Betelgeuse and Rigel are close to the same temperature, because they are about the same distance from the Sun.

Which of the following identifies and explains the seasons that are occurring in the Northern and Southern Hemispheres at Point 2?

• Both hemispheres are receiving equal amounts of sunlight causing fall in the Northern Hemisphere and spring in the Southern Hemisphere.

• Both hemispheres are receiving equal amounts of sunlight causing spring in the Northern Hemisphere and fall in the Southern Hemisphere.

• The Northern Hemisphere is receiving more sunlight than the Southern Hemisphere causing summer in the Northern Hemisphere and winter in the Southern Hemisphere.

• The Northern Hemisphere is receiving less sunlight than the Southern Hemisphere causing Wittner in the Northern Hemisphere and summer in the Southern Hemisphere.

A certain reptile species is a herbivore and exists only on an isolated island. Which of the following would most likely result in the extinction of the reptile species over a period of twenty thousand years?

• The reptile species produces many offspring with many unique traits, and the vegetation remains constant.

• The reptile species produces few offspring with some unique traits, and the vegetation remains constant.

• The reptile species produces few offspring with no unique traits, and the vegetation changes quickly.

• The reptile species produces many offspring with some unique traits, and the vegetation changes slowly
