Which statement does NOT describe a law?
It can be tested.
Describes why something happens.
Describes how nature works.
Describes that something will occur every time in a given set of conditions.
Which of the statements below explain why theories are modified but are rarely discarded?
As long as theories are based on information they will be modified and not discarded.
As long as they are factual, theories will eventually become laws and will be modified and not discarded.
As long as they are well supported or proven, theories will become facts and will be modified and not discarded.
As long as a theory still explains a wide range of observations and evidence, it is modified and not discarded.
What type of evidence are you using if you conduct an experiment and draw conclusions that relies on gathering and evaluating evidence?
deductive evidence
subjective evidence
empirical evidence
inductive evidence
Ptolemy believed that all objects in space, including the Sun, revolved around Earth. Nicolaus Copernicus made observations showing that Earth and other planets revolved around the Sun, which refuted Ptolemy’s argument. What is this an example of?
Scientific knowledge starts as a scientific theory and becomes a scientific law.
Scientific knowledge is communicated between scientists.
Scientific knowledge always stays the same.
Scientific knowledge changes as a result of new evidence.
Brandon noticed that hummingbirds in his yard visited all the flowers, but especially seemed to like the red trumpet-shaped ones. He read that they use the nectar in the flowers for food. He assumed that since the parents were eating nectar, they must feed their babies nectar as well. To his surprise, he saw hummingbirds bringing small insects and spiders to feed the young hummingbirds. How does this new evidence affect his original assumption?
He should change his original assumption that they only feed their babies nectar.
He should be able to stick to his assumption that the babies eat nectar since he thought that first.
He should believe what he read in the book and disregard what he witnessed.
He should ask other people what they think and agree with the majority.
Which waves on the electromagnetic spectrum have the lowest frequency and longest wavelength?
gamma rays
visible light waves
microwaves
radio waves
If you were drawing a diagram of the EM spectrum, which type of wave should be placed be placed between infrared and ultraviolet?
visible light
long wave
short wave
non-visible light
You may see something under water and reach into the water to pick it up. However, the object is not where you thought it would be. What property of light is responsible for this?
absorption
transmission
refraction
reflection
Jimmy told his friend about the rainbow he saw just after a rainstorm. Jimmy then explained to his friend how a rainbow forms. What was Jimmy’s explanation?
The intensity of light increased as the waves passed through tiny droplets of water.
Light traveled faster after the rainstorm because of the moisture in the air.
Tiny droplets of water reflected the light waves that struck them.
The light waves were refracted by moisture in the air.
Which of the following materials would sound travel fastest through?
a wooden desk
a sponge
a beaker of water
the air in the room
Which of the following materials would light travel fastest through?
plastic
air
water
light waves travel the same in each one
How does the speed of light in water compare to its speed in air?
The speed is the same in water because it is constant in all mediums.
The speed is faster in water than in air because the molecules are closer together.
The speed is slower in water than in air because the molecules are closer together.
The speed cannot be compared without knowing the temperature.
The distance between which two objects or places would BEST be measured in light years?
Boston and Los Angeles
Our Sun and the nearest star
Earth's maximum distance from Saturn
Earth's surface and an orbiting satellite
Space exploration has advanced our knowledge of the universe. Which space journey would take the longest amount of time?
a trip from the Earth to the Sun
a trip from the Earth to the Moon
a trip from the Earth to a star in the constellation Centaurus
a trip from Earth to Neptune, the farthest planet in our solar system
Which of the following statements does NOT support how scientists have built upon knowledge over time?
We build upon prior knowledge from the past.
Many early science discoveries were foundational.
Some of the early science has been proven to not be valid.
Only current discoveries are important as we move forward.
Which of the following technological innovations is described correctly?
The telescope allows us to examine microorganisms with great detail that were once invisible to us.
Fiber optics allows large amounts of information to be transmitted around the world in just a few seconds.
Computers allow us to peer into space and view distant stars and their exoplanets.
Microscopes can handle huge amounts of data and can be used in all fields of science.
Sunlight is composed of energy that is visible to humans and energy that is not visible to humans. Which statement describes how the visible energy from the Sun is different from the nonvisible energy?
It has different wavelengths.
It travels at a different speed through space.
It cannot travel through the vacuum of space.
It travels a different distance through space.
Which of the following statements about the electromagnetic spectrum is NOT true?
Long wave radiation has high energy.
Short wave radiation has high energy.
The electromagnetic spectrum includes visible light.
The energy in the electromagnetic spectrum is related to its wavelength and frequency.
Which set of the spheres on Earth would BEST represent animal species in a forest?
atmosphere, geosphere, cryosphere
geosphere, hydrosphere, atmosphere
biosphere, geosphere, atmosphere
cryosphere, biosphere, and hydrosphere
The coast line of Antarctica is receiving increased snow fall as well as ice melt over the past 10 years. What would be the MOST LIKELY reason for this occurrence?
Decreased surface temperature produces less ice, resulting in less snow fall in the region.
Increased surface temperature evaporates more ice, resulting in less snow fall in the region.
Decreased surface temperature produces more ice, resulting in more snow fall in the region.
Increased surface temperature evaporates more ice, resulting in more snow fall in the region.
Karen is teaching her younger brother about interactions on Earth. She tells him that the geosphere and hydrosphere are in constant interaction. What evidence could she use to support her statement?
Rain falls on the ground and runs along the surface of the ground, eroding soil and depositing it into a nearby lake bed.
The Sun's energy evaporates water which rises as water vapor and condenses as clouds.
Tree roots weather rock by breaking it into smaller pieces.
Moist soil allows Earthworms to absorb oxygen through their skin.
Which feature of the stratosphere helps to protect Earth from the Sun’s ultraviolet radiation?
carbon dioxide
nitrogen
ozone
water vapor
The peak of Mount Everest is at an elevation of almost 9 km, entering the lower stratosphere. Why would a mountain climber need an air tank to breathe when climbing Mt. Everest?
air is less dense at this altitude
air is too cold to breathe safely at his altitude
air is too dense to breathe safely at this altitude
air is too warm at this altitude
24. Two students, Maria and Henry, are discussing the following question, “How does the composition and structure of the atmosphere influence life on Earth’s surface?”
MARIA: The Earth’s atmosphere insulates Earth’s surface by absorbing radiation that reflects off of Earth’s surface and trapping it in the lower atmosphere, keeping surface temperatures from being too cold.
HENRY: The Earth’s atmosphere protects life on Earth’s surface by absorbing or reflecting some harmful radiation from the Sun before it reaches Earth’s surface. This is especially important for humans. Which student is correct in their reasoning?
Henry's reasoning is correct.
Both Maria and Henry are correct in their reasoning.
Only Maria's reasoning is correct.
Neither Maria or Henry are correct in their reasoning.
