Scientists discuss and debate experimental results and possible explanations in studying phenomena. Which best explains why scientists debate while searching for explanations?
Every scientist wants to find an accurate explanation and disprove others’ explanations.
Debating gives scientists an opportunity to express their feelings and opinions about the subject.
Debating helps the scientific community to present interesting and exciting science to the public.
Debating helps scientists focus on empirical evidence, analyzing both the strengths and weaknesses of the evidence.
Sunscreen bottles often include the phrase: “Protects against UVA and UVB waves.” This refers to ultraviolet radiation coming from the sun. Which of the following is true of ultraviolet radiation?
Ultraviolet radiation has shorter wavelengths than x-rays, therefore it is more dangerous than x-rays.
Ultraviolet radiation has shorter wavelengths than visible light, therefore it is more dangerous than visible light.
Ultraviolet radiation has longer wavelengths than infrared light, therefore it is more dangerous than infrared light.
Ultraviolet radiation has longer wavelengths than gamma radiation, therefore it is more dangerous than gamma radiation.
Electromagnetic radiation is energy that travels in waves. Two types of electromagnetic waves are X-Rays and Radio Waves. X-Rays have a shorter wavelength than Radio Waves. Which of these statements is true?
X-Rays have more energy than Radio Waves do.
X-Rays travel slower than Radio Waves in a vacuum.
X-Rays have a lower frequency than Radio Waves do.
X-Rays, but not Radio Waves, can travel through a vacuum.
Mrs. Smith added a room-temperature copper (Cu) cube and an aluminum (Al) cube that she just removed from the freezer to a beaker of boiling water. She left the cubes in the water for three hours. Which of the following describes the heat flow that took place during those three hours?
From the aluminum cube to the beaker
From the copper cube to the boiling water
From the aluminum cube to the copper cube
From the boiling water to the aluminum cube
The picture below shows a metal bar with three thermometers on it suspended over a flame on one end. If you were to remove the heat source from the metal bar, what would you expect to occur next?
You would expect all heat transfer would stop immediately on the metal bar because the heat source was removed.
You would expect heat would continue to transfer from hot to cold until the metal bar reaches thermal equilibrium and all the thermometers would display the same exact temperature.
You would expect heat would continue to transfer from cold to hot until the metal bar reaches thermal equilibrium and all the thermometers would display the same exact temperature.
You would expect heat would continue to transfer across the metal bar from hot to cold until the thermometer farthest from the flame would now have the highest temperature being displayed.
X-Rays have a higher frequency than Radio Waves do. Which of these statements is true?
The speed would increase if the wave moved from a liquid to a solid.
The speed would decrease if the wave moved from a liquid to a solid.
The speed would not change if the wave moved from a liquid to a solid.
The speed would not exist as mechanical waves cannot travel through a solid.
While attending a baseball game of his favorite major league team, Takahiro notices that he can see the batter hit the ball before he hears the crack of the bat. Which of the following statements best explains why there is a time lapse between seeing the baseball hit and hearing it?
A time lapse occurs because eyes react to stimuli faster than ears do.
A time lapse occurs because light waves travel in a more direct path than sound waves.
A time lapse occurs because sound waves travel more slowly in the air than light waves do.
A time lapse occurs because sound waves from other sounds cause interference with sound waves from the bat.
When a pencil is placed in a glass of water, the pencil appears broken at the surface of the water. Why does this occur?
This occurs because the light does not change speed.
This occurs because the light stops when it hits the water.
This is because the light slows down as it moves from water into air.
This occurs because the light speeds up as it moves from water into air.
As light travels through different types of matter, it may be absorbed, reflected, or refracted. Which statement is accurate about the properties of light in the diagram?
As light travels from the air through the water, some of it is refracted (Example 1), absorbed (Example 2), and reflected (Example 3).
As light travels from the air through the water, some of it is reflected (Example 1), absorbed (Example 2), and refracted (Example 3).
As light travels from the air through the water, some of it is reflected (Example 1), refracted (Example 2), and absorbed (Example 3).
As light travels from the air through the water, some of it is absorbed (Example 1), reflected (Example 2), and refracted (Example 3).
A model helps scientists understand the natural world. For example, the model of a wave shown below helps scientists understand wave movement. What is one benefit of using a model such as the one shown in the diagram?
It helps scientists investigate how waves can be reflected or refracted.
It helps scientists investigate how energy is conserved in wave motion.
It helps scientists investigate wave properties that are hard to visualize.
It helps scientists investigate waves motion traveling in multiple mediums.

Example C
Example D
When a volcano erupts, particles of rock and ash are released into the atmosphere. After this, water droplets form around the rock and ash particles and fall to Earth as rain. The rainwater helps plants grow. In this scenario, which spheres of Earth interact?
Cryosphere, geosphere, biosphere
Biosphere, cryosphere, hemisphere
Geosphere, hydrosphere, biosphere
Hydrosphere, cryosphere, geosphere
Which statement best describes the energy changes associated with evaporation and boiling?
Atoms gain energy during evaporation and boiling.
Atoms lose energy during evaporation and boiling.
Atoms gain energy during evaporation but lose energy during boiling.
Atoms lose energy during evaporation but gain energy during boiling.
Sara was researching the properties of solids, liquids, and gases for her science class. She found the diagram below that represented equal masses of the same substance in three phases. How should Sara describe the atoms of the liquid?
Sara should state that the atoms in a liquid have a greater force of attraction than the gas only.
Sara should state that the atoms in a liquid have a weaker force of attraction than the gas only.
Sara should state that the atoms in a liquid have a greater force of attraction than the atoms of a solid and a gas.
Sara should state that the atoms in a liquid have a weaker force of attraction than the atoms of a solid and a gas.
Which graph best shows the general relationship between the temperature of a gas and the speed of the molecules in that gas?

Jason states the following prediction: "As the air temperature increases, the air in a balloon will expand, increasing the circumference of the balloon". Which of the following is the test variable (independent variable) for an experiment designed to test Jason’s prediction?
Air Temperature
Material of the balloon
Circumference of the balloon

Which statement explains the relationship between the density of a material and its movement in Earth’s interior?
Cooler materials move from Earth’s mantle to the lithosphere.
Cooler materials are highly dense, causing them to sink to the outer core.
Warmer materials sink to the mantle because their density slowly decreases.
Warmer materials have a high density, causing them to rise to Earth’s surface.
