Design processes
What is technology?
What is: science for practical purposes.
Name forms of matter.
What is: Mass, Density, Volume.
1 newton = ? pounds.
What is: 0.25 pounds.
How do you test the reliability of an experiment?
What is: Redo the experiment many times.
What is the use of Engineering Design Process?
What is: It helps identify & and meet a need.
Name the Variables in an experiment.
What is: Controlled variable, Dependent Variable, Independent variable.
What is not matter?
What is: Light & Sound.
Name the formula for mass.
What is: Density x Volume.
What sites can you trust and not trust for reliable scientific information?
What is:
Trust = Scientific journals, Government sites, research by scientists,etc.
Don't trust = Commercial sites.
What skills do you need to be an engineer?
What is: Math, Science, Tech, thinking Methodically, thinking Creatively.
Name steps for E.D.P.
What is: Identify need, Conduct research, Brainstorm, Redesign to improve, Communicate results, Test & Evaluate.
Name units of Volume, Mass, and Length.
What is: Liters, grams, and meters.
Name the formula for volume.
What is: Mass/Density.
Name 2 things (other than redoing an experiment) you can do to make a good experiment?
What is: Make a controlled experiment and do peer review.
Name 2 types of technology.
What is: Complex and Simple.
Provide 2-4 constraints.
What is: Time, Materials, budget, Environment.
Name ways to measure weight.
What is: Triple beam measure, Spring scale, normal weighing scale.
How do you find volume of irregular shaped object?
What is: Water displacement.
Why do scientists write down every detail of an experiment?
What is: So they can do over the experiment to compare results.
What do you do if your prototype doesn't work?
What is: Brainstorm solutions.
List steps in Scientific Process.
What is: Define problem, Plan investigation, Form Hypothesis, Identify variable, Do Experiment, Collect and organize data & analyze data, and Draw conclusion.
Density
a. What is density of water?
b. Name inequality for sink or float of an object by its density and the water's density?
What is:
a. 1g
b. if object > 1g, sink.
if object < 1g, float.
if object = 1g, stays below surface of water.
How do you find density of an object.
What is: Mass/Volume.
Name 3 types of organized data.
What is: Spreadsheets, Tables, Graphs.
What is a trade off?
Trading off one advantage for another in order to meet constraints.
