Multiple Choice

Which of the following might be an example of a theory?

1

You develop an equation that successfully predicts the size of a crater given the size of the meteor

2


You publish a paper analyzing the elements that make up a sample of a meteorite

3


You develop an idea about why the frequency of meteor impacts varies in a consistent pattern over several decades of observation

4

Multiple Choice

What made Mendeleev's theory about the organization of matter in the periodic table so powerful?

1


His theory predicted unknown elements that were later found

2


His theory later 'grew up' into a law about elemental properties

3

He was the first scientist to attempt to organize elements in a pattern

4


When he paired oxygen with potassium, it went 'OK'

Multiple Choice

One can best compare the acceptance of a theory to:

1

A foot race, where the first theory that comes up with an explanation wins

2


A lottery, where if you happen to be really lucky, you can win a prize

3

A boxing match, where the winner has to be ready to fight the next opponent

4

A cafeteria line, where scientists can just pick and chose parts they like best from each theory

5

Multiple Choice

Which of the following best describes how theories relate to laws?

1

Theories are laws that have not been proven true yet

2

Theories attempt to explain why things happen and laws predict what will happen

3


Laws are theories that have not been proven true yet

4

Laws attempt to explain why things happen and theories predict what will happen

6

Multiple Choice

New data is found which goes against what scientists predicted should happen. Which of the following is NOT a potential result of the new research?

1


A current theory is discarded because it cannot explain the new data

2


A current law is charged to account for the new data

3

A current theory is modified to better explain the new data

4

Any of these are possible responses to new and unexpected data
