Science
Anything that is made to meet a need or desire is a ________________.
Technology Product
An original or test model on which a real product is based is called a ____________.
Prototype
Marco is using a computer to help him find information for a report. Which statement best describes the computer as the object used?
it is a TOOL
You probably use the tools shown below every day (telephone/pencil and paper). What is a true statement about these tools?
They are both examples of technology.
Identify the goal, input, output, and feedback of the solar cell system.
Goal: use solar energy to generate electricity.
Input: planning, material, cost, and solar energy.
Output: electrical energy.
Feedback: reduced use of commercial energy.
Design
Tools, parts, and processes that work together form a ___________.
Designed System
Researchers want to build a new type of spaceship for transporting astronauts to the moon. What should they do first?
They should plan a PROTOTYPE
Sometimes a prototype tests poorly or fails completely. What should be done when that happens?
The prototype should be modified, with the good parts of it kept.
So the design can be duplicated.
A designed system, product, or process that people use to solve problems is called ___________.
Technology
Anything that helps people shape, build, or produce things to meet their needs is called a _______.
Tool
Bulldozers, measuring cups, pencils, and hammers are all examples of tools. What else can be said about all of them?
They are all technology products.
A fuel-efficient automobile is an example of a designed system. What is an example of feedback for such an automobile?
Data on how much fuel the car used to travel 100k.
Why should the engineer build a prototype of the shoes?
To test and identify problems before the final design goes into production.
A series of steps used to achieve a goal or make a product is called a ___________.
Technology Process
A group of researchers are working on a way to make winter coats warmer. The first coat the researchers' design is not very warm. What should they do?
They should examine their test data for ways to improve the coat's design.
New solutions to problems often begin with a "What if?" question. Which "What if?" question would an engineer ask after seeing the electrical energy station shown below? (a building with smoke stacks and smoke coming out)
What if we could burn coal to make electricity without polluting the air?
Long ago, there were few roads. Now, there are many roads. How has a system of roads changed most communities?
People can easily get from one place to another.
Describe a part of the design process the engineer should do AFTER testing the prototype.
1. Evaluate the design and modify it if necessary.
2. Any redesigned prototype should also be evaluated through a series of repeated tests until it meets the design criteria.
3. The final design solution should be presented using graphs or drawings so others can replicate the work.
The use of scientific and mathematical principles to develop something practical is called ___________.
Engineering
Sylvia works for a car company. She uses her knowledge of math and science to design dashboards that make it easier to operate cars. What is Sylvia's profession?
Engineer
Angie tested a reflector that she hopes will make bicycles safer. Although her first test went well, she repeated the test three more times. What is a true statement of the data she received?
She obtained more accurate data than if she had only tested the reflector once.
A picture shows solar cells on the roof of a house. These cells take solar energy and convert it into electricity that appliances in the house need to function. *Use reasoning to support the claim that solar cells are part of a designed system*
A designed system is any group of tools and processes people put together to solve a problem. The solar cells are connected to the home's electrical system and its electrical appliances.
