Definitions- Name it
the features or qualities the solution of a design problem should have
what is criteria
Define outputs
product of the system
What three things can influence technology?
1) Scientific knowledge
2) Environmental/ Natural Resources
3) Society
Give an example of a system model
Ex: earthquake shake tables & model buildings used to replicate what would happen during an earthquake.
the limitations that engineers face during the design process
what is "constraints"
Define boundaries
defines edges of a system (limits/ borders)
How does scientific knowledge affect technology?
As we learn something new, we can build it or improve it.
What problem was a backpack designed to address?
Making it easier to carry a heavy load.
Making it easier to carry many items.
anything that needs to be addressed in the world
what is problems
Define components
the parts of the system that interact and carry out a process
What are some advantages of investigating with a system model compared to carrying out investigations on a real-world system?
safer, less expensive, and easier to study
Give an example of how using a natural resource to make a technology has impacted the environment.
Using oil has caused pollution.
Cutting down trees has caused habitat loss.
Mining for minerals has cause harmful chemicals to be released.
the use and application of science and math to solve problems
What is engineering
Define Iterative Testing
design testing that is repeated many times
What two components play a role in determining which technologies are developed and used?
a communities values & environmental conditions
Give an example of a technology solution that was inspired by nature
What is inputs
Define system
a set of interacting parts that work together
What are the 6 parts to the engineering design process?
1) Define the problem
2) Identify Needs
3) Develop Solutions
4) Test Solutions
5) Consider trade-offs
6) Optimize solutions
Give an example of how changing one component in an ecosystem can affect another component within that same ecosystem.
Adding wolves back into Yellowstone increased the number of trees, because elk were now prey to the wolves so fewer elk were eating tree saplings.
