Earth/Space Review

Match

A student conducts an experiment in which she drops objects, each with a different mass, all from the same height. She uses a stopwatch and records the time it takes for each object to hit the ground. Match the variables for the experiment.

• Dependent Variable

• Controlled Variable

• Independent Variable

time the object travels

height at which object is dropped

mass of the object

• time the object travels

• height at which object is dropped

• mass of the object

Kaylee reads an article that states that the frequency of chirping by crickets is related to the temperature of

their environment. She wants to conduct an experiment to see if this is true. Kaylee thinks

crickets chirp more frequently when the temperature of their environment increases. Match the variables with the parts of the experiment they describe. (careful its tricky)

• Dependent Variable

• Controlled Variable

• Independent Variable

number of cricket chirps

number of crickets

temperature of the environment

• number of cricket chirps

• number of crickets

• temperature of the environment

Multiple Choice

Scientific theories are based on

• general assumptions of how systems work.
• mathematical principles that can be proven true.
• large amounts of data collected over time.
• observations from within only one scientific discipline.

Multiple Choice

In 1897, Joseph Thomson discovered that atoms contained electrons.  He proposed a change in the atomic theory of that time, and the theory was modified because of his discovery.  Since Thomson’s discovery, atomic theory has been further modified.  What is the best explanation for why scientific theories are modified?

• Theories more than ten years old are usually out of date.
• Scientists want to prove that the work of other scientists is wrong.
• New evidence that supports a revision prompts scientists to modify earlier theories.
• So much information is available today that it is harder to focus research and disprove theories.

Multiple Choice

Which statement below correctly identifies the difference between laws and theories?

• Laws describe phenomena, while theories explain why and how phenomena exist

• Laws are a statement of fact, while theories are a statement of opinion

• Laws explain why phenomena exist, while theories explain how

• Laws are a prediction of phenomena, while theories are an explanation
