100
Each time you try an experiment is called....
What is a trial?
100
This makes a good hypothesis!
What is it is testable and educated guess based on experience.
100

Scientific discoveries are used by these people to design technology and solve problems.
What is an engineer?!
300
This is situation set up to investigate relationship between two variables.
What is an experiment?!
