What is tech.? the use of knowledge and resources to develop products and systems to satisfy people's needs or wants.
why do we study tech.? so that we can understand,use, and manage it.
how is tech. used? used to solve problems and extend our capabilities.
how fast is tech. growing ? exponentially
names the main types of tech. and how they are used medical- vaccines,medicine,and surgery. agricultural- pest control,irrigation,and other tech. for farming. energy- all sources,fossil fuels,wind,water, and sun. communication- using one form or another to send and receive info.
what are the basic steps in the problem solving method 1. understanding the problem. 2. gathering info. 3. developing solutions. 4. implementing solutions. 5. testing and evaluating. 6. redesign and communication.
what is a system? a combination of parts that work together to achieve a desired goal.
how does a systems model work? inputs -> process or resources -> output -> feedback -> back to inputs
list the parts of a systems model and explain what they do input- the different possible solution ideas process or resource- the amount of goods and services available to be used. output- the outcome as a result of the input and resources that are used.
what types of outcomes can systems create? desired, expected, undesired, unexpected
name the different tech. eras and explain their significance Prehistoric- hunting and gathering tools. Agricultural- growing food. Industrial- mass producing goods. Informational- technology age.
what is energy? the ability to do work
what is work? the process of transferring energy
what is potential energy? energy of position, energy that is not in use but available
what is kinetic energy? energy of motion or energy that is in use
what is law of conservation of energy? energy can't be created or destroyed by ordinary means, but can be converted from one form to another
what is energy transformation? the changing of energy from one form to another
what is gravitational potential energy? potential energy that is dependent on height
what can be used to maintain control of an object while it is going down a slope? friction
what will happen to an object that goes down a slope too steep? it will become out of control and will not be able to stop at the end.
the first hill on any roller coaster is very important because it must? create enough gravitational potential energy for the coaster to go through the rest of the track without needing any more power.
what are ethics? ethics are concerned with standards, rules or guidelines for morally or socially approved conduct, such as being honest or trustworthy or acting in the best interest of society.
