S2U2L1-2 review

This is a review for Unit 2 Lessons 1-2 Technology And Our World

Engineers use a process to design new technology to meet human needs. Technology affects our everyday life and can affect the environment around us.​

Multiple Choice

Engineers solve problems by using _______ and _________.

• math and science

• math and language

• science and technology

• science and geography

Design Process

is a set of steps that engineers follow to solve problems

Multiple Choice

What is the first step in the design process?

• plan and build

• find a problem

• redesign

• communicate

The Second Step

The second step in the design process is plan and build a solution

Multiple Choice

What happens during this step? (Plan and build)

• You figure out what you want to do to solve the problem and choose the materials you will need.

• You test your creation and work on how to improve it.

• Communicate to everybody what you are building by sharing ideas.

Engineers work in many areas

Some engineers design cars, some make robots. Others find ways to make the world cleaner or safer.

Multiple Choice

What do you call an engineer that works on planes and rockets?

• A civil engineer

• A robotics engineer

• An aerospace engineer

Open Ended

Why are engineers important?

How are engineers and design process related?

The design process guides engineers as they solve problems.​

Multiple Choice

What does a civil engineer do?

• plans bridges and roads

• designs robots

• builds airplanes and rockets

Multiple Choice

Steps that engineer follow to solve a problem

• the problem that needs solution

• plan and build

• design process

Multiple Choice

The answer to a problem

• solution

• redesigning

• build and test

Multiple Choice

How you find out whether a solution works

• plan and build

• test

• communicate

Multiple Choice

Things you use to make a design

• problems

• materials

• solution

What is a process?

A process is a series of actions. These actions produce a result.

There are many types of engineers. Bio means “life.” Biology is the study of life. What would bioengineers do for their work?

Bioengineers use biology, math, and engineering to solve problems. They find ways to help the body. They also develop medicine to keep the body healthy. Bioengineers often work in hospitals or labs. 

The H-4 Hercules

was the biggest flying plane ever built. Only one was built and it only flew one time. Why might this be the case?

The H-4 Hercules, nicknamed the “Spruce Goose,” was designed by engineers for use during a war. However, the war ended before the first plane could be completed. Therefore, the engineers did not need to build more.

Multiple Choice

What does it mean to design?

• to make a plan to do or build something

• to rebuild and make improvements

• To communicate the results

Multiple Choice

What is a process?

• a line of material for your design

• a number of steps and decisions that plans the way work is done.

• a series of unfortunate events

Multiple Choice

Why do people invent things?

• because they are told by their teachers

• because they want to do something about the extra materials lying around

• because they want to do something in a better way

Multiple Choice

What are NOT technological tools we use to communicate with other people who are far away?

• telegraph

• paper and pen

• television

• internet

Multiple Choice

Why do you think it is important to use the smallest possible parachute in a design to keep the egg from breaking?

• A larger parachute costs more to make.

• the smallest possible parachute is better matched with the small egg.

Multiple Choice

What other solutions—in addition to using a large parachute size, using a high release height, and wrapping the egg—can you think of for safely landing a parachuted egg?

• You could also plan the best landing area for the egg.

• setup in a rocky ground landing

Open Ended

What did you learn from the egg-parachute experiment?
