Communications
Johannes Gutenberg invented this technology in the the 1450s which helped to spur on the Protestant Reformation, the Renaissance, and explosion of scientific discoveries.
What is the Printing Press?
The invention of this technology by James Watt helped spur the Industrial Revolution. It was used in mills, power boats, and power trains.
What is the steam engine?
This technology detects objects with radio waves.
What is RADAR?
RADAR stands for RAdio Detection And Ranging. Radio waves are sent out from a transmitter until they hit an object. The receiver receives the radio waves that bounced back. The RADAR system translates this information into a visual picture and provides information about where an object is located.
Elias Howe contributed to this invention which used a needle that has an eye that is at the bottom rather than the top.
What is the sewing machine?
Anton van Leeuwenhoek was one of the first scientists to build this technology, allowing him to see objects enlarged up to 270 times and able to see bacteria and other organisms.
What is the microscope?
Thomas Edison and his team tested over 1600 different materials to serve as the filament in this invention.
What is the light bulb?
Samuel Morse invented this technology which allowed people to communicate over long distances over wires using Morse Code.
What is the telegraph?
Trains today usually use this kind of engine.
What is the Diesel engine?
This technology detects objects using sound waves.
What is SONAR?
Sonar stands for SOund Navigation And Ranging. A transmitter sends an ultrasonic sound wave which travels through water and reflects off of solid objects. These reflected sound waves are detected by the sonar system and translated into pictures.This invention uses energy waves to excite water molecules to heat up food.
What are microwave ovens?
Wilhelm Roentgen helped to develop this technology which allows doctors to see bones and other parts of the body.
What is x-ray?
Edison, who was hard of hearing, improved this invention by Alexander Graham Bell's by amplifying the sound of the receiver.
What is the telephone?
This communications technology was developed about 50 years after the telegraph thanks to the inventor Gugliemlo Marconi, making it possible to send messages (and entertainment) hundreds of miles away without wires.
What is Radio?
This man designed the assembly line and made it possible for the automobile to be affordable to many people.
Who was Henry Ford?
This technology revolutionized warfare and weaponry.
What is Gun Powder?
The light bulb cannot have this gas inside it because the fillament will burn up quickly.
What is oxygen?
Computers store information in a series of 1s and _________.
What is 0s.
In order to power up light bulbs with electricity in homes, Thomas Edison had to develop this.
What are power stations?
The original televisions (before flat screen TVs) had a large tube inside called the picture tube or CRT. This is what CRT stands for.
What is Cathode Ray Tube?
The front of the CRT was the screen that you watch.
This type of engine does not use spark plugs like the internal combustion engines. It is more effecient, but requires a heavier engine, so it is used for larger vehicles.
What is the diesel engine?
A British soldier named Ernest Swinton invented this vehicle that moved on caterpiller tracks and protected soldiers as they travelled.
What is the Tank?
Hydrofluorocarbons are used in the pipes of this device to help remove heat.
What are refrigerators?
Refrigerators use HFCs (hydrofluorocarbons) as the liquid refrigerant.
This part of the computer stores short-term memory. It is abbreviated RAM.
What is RANDOM ACCESS MEMORY?
It holds the commands that will be used soon or have been used recently.
What is a camera?
A satellite that always orbits above the same part of the earth.
What is geosynchronous?
Communication satellites receive and send radio signals to different parts of the Earth. Geosynchronous satellites are in high orbits and move at the same speed that the Earth is spinning.Werner von Braun, a German scientist, helped to develop this technology that would travel to space.
What is a Rocket?
John Phillip Holland improved the development of this technology that utilizes ballast tanks that would add or take away sea water to create weight.
What is the submarine?
Clocks use this simple machine to maintain a set rate.
What are pendulums.
What is the Central Processing Unit?
This is the part of the computer that does most of the calculations and tells the other parts of the computer what to do.
This was the first device used to record sound.
What is the phonograph?
