What happens when the data in an investigation do not support the original hypothesis?

The scientist gives up and starts an investigation on a new topic.

The data must be incorrect and are thrown out.

The data are altered so that they support the original hypothesis.

Which of the following statements is true about scientific theories?

Scientific theories are never proven.

Scientific theories become scientific laws.

Scientific theories become hypotheses.

Scientific theories summarize patterns found in nature.

Why are scientific models important?

They help visualize things that are very complex, very large, or very small.

They prove scientific theories.

They make it harder to understand things.

What is the most important safety rule?

Always follow your teacher's instructions and textbook directions exactly.

Always use unbreakable glassware.

Never do experiments that involve flames or hot objects.

Which of the following is an example of a safe laboratory procedure?

tying back long hair and loose clothing

eating or drinking from laboratory glassware

touching hot objects with your bare hands

testing an odor by directly inhaling the vapor

Which of the following clocks offers the most precision?

a clock with a hand to measure the hour, a hand to measure the minutes, and a hand to measure the seconds

a clock with only one hand to measure the hour

a clock with only one hand to measure the minutes

a clock with a hand to measure the hour and a hand to measure the minutes

How do scientists communicate the results of investigations?

by publishing articles in scientific journals

by giving talks at scientific conferences

How do scientists who speak different languages make their data understandable to one another?

They all use different systems of measurement.

They communicate through a universal translator.

What is a peer review?

a process in which scientists examine other scientists' work

a process in which only close friends of a scientist review the scientist's work

a process in which scientists copy other scientists' work

a process in which scientists keep their work secret

Why are peer reviews important?

Scientists receive questions and criticism from their peers.

Scientists receive comments and suggestions from other scientists.

A mechanical wave generally does NOT

move the medium from one place to another.

Transverse and longitudinal waves both

transfer energy through a medium.

have compressions and rarefactions.

move at right angles to the vibration of the medium.

are capable of moving the medium a long distance.

In an earthquake, a P wave is a longitudinal wave. It moves through soil and rock as a

series of compressions and rarefactions.

A period is the length of time it takes for

one complete wavelength to pass a fixed point.

two complete wavelengths to pass a fixed point.

a wave to travel the length of a rope.

To determine the speed of a wave, you would use which of the following formulas?

speed = wavelength × frequency

speed = wavelength × amplitude

To find amplitude, measure

from a trough to the rest position.

from a crest to the rest position.

To what is amplitude related?

the amount of energy carried by the wave

the maximum displacement from the rest position

How does reflection differ from refraction and diffraction?

Reflection is the only process in which the wave does not continue moving forward.

Reflection is the only process that involves a change in the wave.

Reflection affects all types of mechanical waves, but refraction and diffraction do not.

Reflection is the only process that changes the direction of a wave.

For refraction to occur in a wave, the wave must

enter a new medium at an angle.

strike an obstacle larger than the wavelength.

change direction within a medium.

In refraction, when a wave travels from one medium to another, it

always moves in the same direction.

travels in the opposite direction.

Which wave will probably be diffracted the most by an obstacle?

the wave with the longest wavelength

the wave with the highest amplitude

the wave that strikes a solid barrier with the slowest speed
