Civil Engineering
What common building material is made by mixing cement, water, sand, and gravel together?
concrete
What does the acronym CAD stand for when designing 3D models on a computer?
Computer Assisted/Aided Design
What stores chemical energy and converts it into electrical energy?
Battery
What do programmers call an error or mistake in a computer program's code that stops it from working right?
A bug
At what temperature Celsius does pure liquid water freeze into solid ice?
What do you call a vertical post or pillar that holds up a bridge or a roof?
column (or pillar)
Which hand tool is specifically used to tighten or loosen hex-headed nuts and bolts?
wrench
What is the term for the continuous flow of electricity through a wire?
If you want a computer program to repeat a specific action 10 times in a row without rewriting the code 10 times, what coding structure would you use?
Loop
What do we call energy generated from natural resources that never run out, such as sunlight, wind, and water?
Renewable Energy
What piece of personal protective equipment (PPE) must you wear on your head to protect against falling objects at a construction site?
Hard hat
What handheld instrument has jaws and sliding scales used to measure the precise diameter of a bolt or pipe?
Caliper / micrometer
What safety device in your home's breaker panel intentionally melts or trips to break a circuit if too much electricity flows through it?
Fuse
In coding, what is a named container used to store data or a piece of text called?
Variable
What gas makes up the largest percentage (about 78%) of Earth's atmosphere?
Nitrogen
What do engineers call the detailed 2D architectural drawings used to guide a building's construction?
When using a seesaw or a crowbar, what is the stationary pivot point called?
fulcrum
Why are most electrical wires made out of copper metal instead of plastic?
Copper is a good conductor that lets electricity flow easily, while plastic is an insulator that blocks it.
What does HTML stand for, which is the foundational language used to structure text and links on a webpage?
HyperText Markup Language.
What physical process happens when a solid material transitions directly into a liquid because heat is added?
Melting
Why are bridges built with triangles instead of squares?
The triangle is the strongest geometric shape, and it cannot change its angles without changing the length of its sides, making it highly stable.
What slippery substance do engineers add to moving machine gears to stop them from rubbing, overheating, and wearing down?
Lubricant
What does a simple light switch physically do inside a wall to turn a light bulb off?
It opens the circuit, creating a gap in the wire so electricity can no longer loop through.
What data type can hold only one of two possible values: True or False?
Boolean
If a chemical liquid has a pH of exactly 7, is it an acid, a base, or neutral?
Neutral
