Round 1

Which of the following is the basis for good scientific inquiry?

• scientific questions that are easy to answer

• scientific questions that you do not need measurements to answer

• investigation results that other scientists can repeat

• investigation results that depend only on observations made by other scientists.

A student does an experiment about how well different types of glue hold. After he finishes his investigation, his teacher says he should make a graph of his data. Why would a graph be useful?

• A graph show all the steps of an experiment

• A graph will always prove that a hypothesis is correct.

• A graph organizes and displays information.

• A graph must always be part of an experiment.

How do opinions compare to observations?

• Only opinions can be tested.

• Only opinions are formed by using your senses.

• Both opinions and observations are thoughts and beliefs.

• Only observations can be tested.

• What type of cat is the prettiest?

• Which type of cat has the longest life span?

• What different names do people choose for their cats?

How do you make sure that certain factors are not affecting an experiment's outcome?

• by making sure the variables in the experiment are controlled

• by performing the experiment only one time

• by keeping independent and dependent variables separate so that one cannot affect the other

• by changing several variables during the experiment

A student wants to know if the type of soil used will affect how tall a pea plant will grow. She states a hypothesis. She grows six pea plants in different soil. She makes sure all the plants get the same amount of sunlight and water. She measures the height of each plant and writes down the data. Which BEST describes the kind of scientific investigation the student conducts?

• library research

• observation

• controlled experiment

• scientific survey
