Science Engineering and Technology
Science helps us understand the natural world. What does engineering help us do?
Design solutions to solve problems or meet needs.
What is the first step in the engineering design process?
Identify the problem or need.
What is a system?
A group of parts that work together to perform a function.
What is a model in science or engineering?
A. A real version of something
B. A smaller or simpler version used for testing or understanding
C. A random guess
D. A type of technology
B. A smaller or simpler version used for testing or understanding.
What word is this defining?: A working model built to test a design and see if it functions as intended.
Prototype
Anything made by humans to meet a need or want is called what?
Technology
A prototype is best defined as what?
A working model built to test a design.
In a solar oven, what is the input?
Sunlight (solar radiation).
Why do scientists and engineers use models?
Faster, Easier, Safer, and Cheaper
What word is this defining?: Any device, tool, or process created by humans to solve a problem or meet a need.
Technology
Which of these is an example of technology?
A. A hammer
B. A cloud
C. A rock
D. A tree
A. A hammer
What is a criteria in engineering?
Criteria = what the design must do/have
If the energy source in a solar car is removed, what happens?
The system loses its energy input and stops working.
When scientists study how birds glide, which type of investigation is this—scientific or engineering?
Scientific investigation.
What word is this defining?: A smaller or simpler representation used to test, explain, or study something that is too large, complex, or dangerous to observe directly.
Model
How are science and engineering connected?
A. Science uses tools made by engineers.
B. Engineers create tools that help scientists make new discoveries.
C. They are not connected at all.
D. Science is more important than engineering.
B. Engineers create tools that help scientists make new discoveries.
What are constraints in engineering?
Constraints = limits like time, cost, or materials.
In a terrarium model, what energy source drives the water cycle?
The Sun.
What is one limitation of using a model?
A. It might not show every detail or act exactly like the real thing.
B. It works better than the real object.
C. It is always the same size as the real thing.
D. It never needs testing.
A. It might not show every detail or act exactly like the real thing.
What word is this defining?: To make a design as effective or efficient as possible after testing and improving it.
Optimize
Which of these shows science influencing technology?
A. Learning how light works leads to creating cameras.
B. Using cameras helps people find new animals.
C. Building roads helps people drive faster.
D. Plants growing taller because of sunlight.
A. Learning how light works leads to creating cameras.
Why is testing an important step in the design process?
It helps identify problems and improve the design before final production.
How can changing one part of a system affect the others?
Because systems are connected — a change in one part can affect how the whole system works.
Which of these is an example of a model?
A. A paper airplane used to test how a real airplane might fly
B. A real airplane flying passengers
C. The Sun shining
D. A computer game
A. A paper airplane used to test how a real airplane might fly.
What word is this defining?: A group of parts that work together to perform a function.
