Environmental Science Unit 1 Practice Test

Mary is testing the hardness of water. She tests distilled water, kitchen water, river water and spring water. Which is the control variable?

• spring water

• kitchen water

• distilled water

• river water

Scientists frequently repeat the experiments of others scientists. Why is this important in science?

• Scientists often ask each other for help in performing experiments.

• Replication of experiments helps to confirm and verify results

• Scientists frequently perform other scientists’ experiments in order to practice their technique.

• Repeating experiments is an effective way to make sure a laboratory is in optimal condition.

An environmental research group contacts another environmental research group to check the results of a research they are conducting on global temperature. This is an example of what?

• Repetition

• Replication

• Plagiarizing someone else's work

• Falsifying experimental data

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

the environment. She wants to conduct an experiment to see if this is true. Which hypothesis best suits to Kaylee’s experiment?

• Crickets chirp more frequently when the temperature of their environment decrease

• Crickets chirp more frequently when the temperature of their environment increases

• Crickets chirp more frequently when the temperature of their environment freezes.

• Crickets chirp more frequently when it rains frequently.

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

the environment. She wants to conduct an experiment to see if this is true. What is the independent variable and dependent variable in Kaylee’s experiment?

• independent variable: number of crickets; dependent variable: frequency of chirping

• independent variable: temperature of environment;

  dependent variable: frequency of chirping

• independent variable: number of crickets; dependent variable: temperature of environment

• independent variable: frequency of chirping; dependent variable: temperature of environment

A scientists does several trials in the same experiment.

• hypothesis

• question

• repetition

• replication
