Unit 2 Science Test Practice

Who is an engineer?

• a person who makes problems by using tests

• a person who finds problems by observing solutions

• a person who solves problems by using math and science

What is the design process?

• a plan to test if a problem exists

• a way to pick out materials to make a solution

• a set of steps that engineers follow to solve problems

What is technology?

• what scientists do to learn more about Earth

• what engineers make to meet needs and solve problems

• what animals and plants use to live in their environments

What is the environment?

• all the technology in the city

• all the living and nonliving things in a place

• something engineers make to solve problems

What is the first step in the design process?

• choose materials

• name the problem

• communicate the results

How do engineers use math and science in their work?

• to read books

• to write letters

• to solve problems
