STEM 1
Why do things fall when you drop them?
gravity
TRUE OR FALSE
Engineers work by themselves!
FALSE
Engineers work together or bounce ideas off each other
What type of spacecraft went to the moon?
A. Space Shuttle B. Rocket C. Flying Saucer
B. Rocket
Why are we choosing to try and colonize Mars and not the Moon?
The Moon does not have an atmosphere or the Moon has too thin of an atmosphere
TRUE OR FALSE
Attention to detail is somewhat needed for engineering
FALSE
Attention to detail is absolutely necessary for engineers!
(+50 points if a specific example is given)
What were stick figures originally drawn on?
Stick figures were originally drawn on caves!
TRUE OR FALSE
Mass is a weight
Mass is NOT weight. While both are forms of measurement, mass will always stay the same unlike weight which can shift.
STEM stands for...
Science
Technology
Engineering
Mathematics
What is Kinetic Energy?
Kinetic Energy is energy in motion
TRUE OR FALSE
Engineers come up with one model and make their final design
FALSE
Several prototypes are made first in order to make sure of safety
What falls faster the bowling ball or feather?
The bowling ball
(+50 if students mention air resistance)
What did Romans use chains for?
Romans used chains to connect and secure objects such as drawing water from a well
Name a part of a rocket
Nosecone, body tube, fins, motor mount, exhaust flame
What is STEM's definition of technology?
Technology is defined as a manmade object or system that solves a problem. So
What is Potential Energy?
Potential Energy is the buildup of energy.
What were bridges originally made of?
Simple materials
(+50 points if any of these were mentioned) wooden logs, stone, and dirt
Our brains do what when watching cartoons?
Chains are durable because the interlocking function allows the chains to distribute weight. While still flexible, any force applied on chains is shared equally instead of just one link.
What is the definition of mass?
Mass refers to the amount of matter in an object
Name a type of engineer!
Construction, mechanical, civil, electrical, computer...
Where was the first successful rollercoaster built?
The first successful roller coaster was actually built in Coney Island in 1884.
What is a prototype?
Prototypes are early versions of a design that keep getting better.
Why are helicopters and airplanes different in the way they fly?
While airplanes are able to get into the air horizontally, helicopters are unique in being able to lift vertically, meaning they can simply go upwards to fly
What were rockets originally made for?
Rockets had to be repurposed from war weapons, to having to carry initially animals and other objects to space before humans could travel.
What is the definition of gravity?
Gravity is an invisible force that pulls objects toward each other
What is the definition of Engineering?
Engineering is defined as the process of creating/using technology to solve a problem or make something easier.
Name a part of an airplane and what it does
Propeller- Results in the aircraft being pushed forward from the resulting pressure difference
Engine- Moves the plane forward with force to be able to fly fast
Wing- Generate most of the lift to hold the plane in the air
Tail- Provides stability during flight, in a way similar to the feathers on an arrow
Etc...
What two forces work together to make bridges work?
Compression and Tension
Which scientist proposed the three laws of motion?
Issac Newton
What is the back of your eye known as?
What is the Retina?
