Here is the complete question:
Caleb wants to find out which type of floor material is best for bouncing tennis balls the highest. Which statement best describes the process he should use?
Options:
-He should use technological design because he will need to make materials.
-He should use scientific investigation because he will need to do an -experiment.
-He should use technological design because he will need to conduct background research.
-He should use scientific investigation because he will need to design a prototype.
Answer:
He should use scientific investigation because he will need to do an experiment.
Explanation:
Scientific investigation refers to the process of finding an answer by using a systematic approaches which commonly accepted by the scientific community.
The process is started by creating initial hypothesis. After the hypothesis is created, Caleb can design an experiment to proof that hypothesis. The experiment must be designed with variables that can be measured,
After that, Caleb need to conduct the test and carefully observe the results. After the concrete results are collected, Caleb need to create a conclusion based on that data.
Caleb can design the experiment dropping each balls on an exact same terrain (for example, he can drop it on a same tennis field and see which one bounced the highest) . This will eliminate the influence of external factors that might temper wit the result.
