Systems
Interacting parts that form a whole
What is a system?
The goal of this area of study is to ask and answer questions about the natural world.
What is science?
The goal of this is to apply scientific understanding to develop solutions.
What is engineering?
The unit measure for mass.
What is a gram?
How long ago the earth was formed.
What is 4.5 billion years ago?
A system that is part of another system
What is a subsystem?
A prediction of what will happen in an experiment based on prior knowledge
What is a hypothesis?
True or false: there are three parts to engineering design.
True!
The unit measure for volume.
What is a liter?
The process where the Earth changes rocks over time through chemical and physical changes
What is the rock cycle?
Energy, information, and matter that ENTERS a system
What is input?
Something you keep the same from trial to trial to ensure a valid experiment.
What is a controlled variable?
Engineers must take these limits and rules into account when solving design problems.
What are scientific principles and impacts on humans and the planet?
The unit measure for length.
What is a meter?
Rocks that have been changed by heat and pressure.
What is a metamorphic rock?
Something that defines the limits of the system to be studied
What is a system boundary?
The variable being purposefully changed by the experimenter.
What is the manipulated or independent variable?
Design solutions can be judged based on these factors.
What is how well the design meets the criteria and constraints of the problem?
The unit measure for weight.
What is a newton?
Rocks that are made of compacted and cemented particles.
What is a sedimentary rock?
A simplified representation of a system that is used to study the system
What is a model?
The variable being measured and recorded.
What is the responding or dependent variable?
These are the three parts to engineering design.
What is define, develop solutions, and optimize?
This glass container looks something like a drink pitcher.
What is a beaker?
Rocks that form when molten rock cools.
What is an igneous rock?
