1.2 Science Review

What is a prototype?

• A final version of a design

• An initial or preliminary version of a design

• A factor that can be changed in an experiment

• A type of scientific test

What is a variable in an experiment?

• A fixed element

• A factor that can be changed

• A type of measurement

• A result of the experiment

What is the first step in the Engineering Design Process?

• Create and test a prototype

• Analyze results and make improvements

• Identify a problem or need

• Research possible solutions

What does a fair test involve?

• Changing all variables at once

• Keeping all variables the same

• Changing one variable at a time

• Not changing any variables

Why is research important in the design process?

• It helps to ignore possible solutions

• It increases the chances of creating an effective solution

• It makes the process longer

• It reduces the need for testing
