On a truss bridge, members connect at points called?
Joints
This long hollow cylinder carries clean water from a treatment plant to homes and schools – engineers design it so water can flow safely underground.
Pipe
These help the train slow down and stop safely at stations
Brakes
This everyday object needs batteries to light up, and you can carry it in your hand when the lights go out.
Flashlight
This furry engineer doesn’t need blueprints or a hard hat, but it still builds some of the best dams in nature.
Beaver
Bridges are made out of this shape to keep the structure strong
Triangle
Name 3 rivers in the United States (200 points per answer).
Hudson River, Mississippi River, Colorado River
This is the front part of the train that pulls all the other cars. It's like the train's brain and muscles combined!
Engine
Name 5 items in your house that use electricity
Lights, television, air conditioning/heater, washer/dryer, electric stove, microwave, refrigerator
This bridge type’s strength comes from its pattern of connected triangles, making it look like a geometry project stretched across a river.
Truss bridge
What is weight from cars, people, or trucks on a bridge called?
Load
This ancient civilization is well known for their water engineering inventions including aqueducts, public baths and sewers.
Romans, Greeks, Mayans, Aztecs
The fastest train in the USA
This famous inventor flew a kite during a storm to learn more about electricity.
Benjamin Franklin
This part of a circuit isn’t a door, but it still “opens” and “closes” to control the flow of electricity.
Switch
When a truss member is pulled, it is in ___
Tension
Name two main ways to control water in an engineering system.
Gravity and Pressure
A force that slows down moving objects or prevents stationary objects from moving
Friction
Name 2 units of electricity (400 points per answer)
Amperes, Volts, Watts
This famous New York City skyscraper can stand tall without swaying too much because engineers packed its core with dense steel columns – it can also be seen from this office !
Empire State Building
When a truss member is pushed, it is in ___
Compression
This process removes dirt, chemicals, and germs for water so it’s safe to drink, often using filters and disinfectants.
What is water treatment?
What does a train need to reach high speeds? (4 options, 500 points each)
Smooth Shape, Strong Engines, Light Materials, Low Friction Tracks
This closed loop provides a path for electricity to flow, allowing electric components (resistors, switches, and power sources) to operate as a functional system
What is a circuit?
This rooftop gadget on electric trains acts like a very polite robot arm, reaching up to “high-five” the overhead wire for power.
