Vocab
The knowledge, processes and products that solve problems and make work easier
Technology
An object orbiting the Earth that can be used to send and receive signals
Satellite
Why is a GPS system an important piece of technology?
GPS technology sends location data from satellites orbiting Earth. They can give users directions to a destination.
What is the first step in the design process?
Identify the problem
After you determine a design solution, what is the next step in the design process?
Build a prototype
A set of steps for developing products and processes that solve problems
Design process
Give two examples of technology that have improved transportation systems.
ex. Cars, trains, planes, etc.
Name two defense systems the body has against germs. How do these systems protect you?
Tears: Flush out the eye
Skin: Stops germs from entering the body
Saliva: First defense against bacteria entering the mouth
Blood: White blood cells attack viruses and bacteria
What are resources you can use to conduct research?
Internet, encyclopedias, books, interviewing experts, etc.
Why is it important to communicate your results with other scientists?
Communicating results allows you to share ideas with others. Other scientists may help you find solutions to problems with your product.
The first fully working product that uses your design solution
Prototype
Give three examples of technology used in your home.
Television, Computer, Microwave, etc. (Accept all reasonable answers)
How does a bandage mimic the job of the skin?
If you have a cut, a bandage protects the open wound from bacteria.
Who designed the world's first piloted and powered airplane?
Orville and Wilbur Wright
What is the main purpose of developing a prototype?
To test whether or not your product will work
A smaller or simpler version of an object
Model
How has train transportation changed over time?
The first trains ran on steam power from the 1800s to the mid-1900s. Then electric, diesel and magnetic levitation trains replaced steam trains. Magnetic levitation trains use powerful magnetics to move just above their tracks. Magnetic levitation trains are faster than diesel-electric trains.
Give two examples of technology at school.
Electronic whiteboard
Intercom system
Chromebooks
Accept all reasonable answers
Once you determine a solution that solves your problem, what are three other factors to consider before building a prototype?
Cost
Time
Safety
What is an unintended problem created by airplane travel?
Accept all reasonable answers
- noise pollution, environmental pollution, etc.
To move people or goods from one location to another location
Transport
Give an example of healthcare technology. Who benefits from this technology?
How have airplane designs changed over time?
The Wright brothers tested gliders and the first motorized airplane that laid the foundation for modern jets that can turn easily.
Explain the design process in your own words.
Accept reasonable responses.
1. Identify the problem
2. Do research
3. Develop possible solutions
4. Choose one solution
5. Design and construct a prototype
6. Test the prototype
7. Communicate results
8. Evaluate and redesign
Why is it important to record your measurements and observations when testing a prototype?
