How can you minimize heat loss in a house?
Insulation, more efficient windows, better siding material
100
What is the first step of the design process? p. 6
Defining the problem
100
What are the three main ways heat can move? (EQ#1)
Conduction, Convection and Radiation

What is density?
It's the amount of mass in a given volume.
It's the degree of compactness.

What two 6th grade classes are important for engineers?
Math & Science
200
What was the goal in the solar oven design challenge?
To create something that would maximize heat gain.
200
What are criteria?
Goals, requirements or standards
200
How does heat travel through a solid? (EQ#2)
Conduction
200
How do you know if something will float in water?
It has a density less than 1.
200
Who designs and create engines and power generators?
Mechanical Engineer
300
What was the goal in the ice cube design challenge?
Create something that would insulate, or minimize heat transfer.
300
What are constraints?
limitations and restrictions such as budget, time, materials, and capabilities
300
How does heat travel through empty space? (EQ#4)
Radiation
300
How do you know if something will sink in water?
It's density is greater than one.

Who designs, and maintains infrastructure like roads, bridges, and dams, as well as public systems like water treatment and sewage?
Civil Engineer
400
What two parts of the water cycle does the Drinking Bird use?
Evaporation and Condensation
400
What is a prototype?
model of a product used to test ideas
400
How does heat travel through a liquid or gas? (EQ#3)
Convection
400
What is densest?
Honey
400
Who designs and manufactures aircraft, spacecraft, satellites, and missiles?
Aerospace Engineer
500
What type of engine is the Drinking Bird?
Heat Engine
500
What is optimizing a design solution?
refining or redesigning to get the best performance or minimizing costs, while satisfying all defined constraints
500
What is the difference between a conductor and an insulator?
Conductors move heat.
Insulators stop heat from moving.
500
Solids are denser than liquids, so why does ice float?
Water forms lattices when it freezes, so there are more spaces in the solid than in the liquid.

Who designs industrial processes that turn raw materials into useful products, such as fuels, medicines, and plastics?
Chemical Engineer
