Bridge Building
I'm a bridge whose deck takes the shape of an "arch."
What is an Arch Bridge?
I am the three types of buoyancy.
What is Positive, Negative and Neutral Buoyancy?
I am a combination of two or more simple machines.
What is a Compound Machine?
I am a substance that carries electric current easily. I have low resistance.
What is a Conductor?
I am a machine that can think, move, and act on its own.
What is a Robot?
I'm a bridge that has beams and footings to support the deck.
What is a Beam Bridge?
I am the amount of matter or "stuff" in an object.
What is Mass?
I am the ability to cause change in an object.
What is Energy?
I am a material that does not carry electric current easily. I have high resistance.
What is an Insulator?
I could help replace a body part.
What is a Bionic?
I'm a bridge with cables and towers to support the deck.
What is a Suspension Bridge?
I am the amount of "space" something takes up.
What is Volume?
I am done when the object moves in the same direction of the force exerted.
What is Work?
I am the smallest particle of matter.
What is an Atom?
I am the four types of sensors in the EV3 kit.
What are Color, Touch, Gyro, Ultrasonic?
I use an arrangement of triangles to support the deck.
What is a Truss Bridge?
I am the Greek word that means "I have found it."
What is Eureka?
I am a combination of a wedge and a wheel and axle.
What is a Gear?
I am a type of "circuit" where there is only one path for electricity to take.
What is a Series Circuit?
I am the part of the robot that responds to the controller and takes action.
What is the Effector?
These two forces have to act in opposite directions for a bridge to work properly.
What are Compression and Tension?
I am the two ways to change pressure on an object.
What are "changing force" and "changing surface area?"
I am the equation for calculating efficiency.
What is Output Work divided by Input Work times 100%?
I am a type of "current" where electricity flows in one direction.
What is Direct Current?
I am used in programming when I want the Robot to do two different actions when it senses two different inputs.
What is a Switch?
