ReplyDeletesir are we suppose to answer these without use of internet ????
ReplyDeletea) Light and Light bulb, Thomas Edison, has tried to invent this 1000 times ( i believe ) and he only succeeded once , purpose of it is to make light (didnt use internet)
b) Since invention of a light bulb, scientist and people had better understanding of the functions of light bulb and electricity. Now people has expanded the use of light bulb to such variety ways and needs.
BAROMETER
ReplyDeleteA barometer is a device that measures air (barometric) pressure. It measures the weight of the column of air that extends from the instrument to the top of the atmosphere. There are two types of barometers commonly used today, mercury and aneroid (meaning "fluidless"). Earlier water barometers (also known as "storm glasses") date from the 17th century. The mercury barometer was invented by the Italian physicist Evangelista Torricelli (1608 - 1647), a pupil of Galileo, in 1643. Torricelli inverted a glass tube filled with mercury into another container of mercury; the mercury in the tube "weighs" the air in the atmosphere above the tube. The aneroid barometer (using a spring balance instead of a liquid) was invented by the French scientist Lucien Vidie in 1843.
This invention has allowed people to predict the whether for peoples knowledge and wellbeing. by predicting the air pressurre this piece of equipment has saved many lives
number 3.... deserves number 1 because of it extensive research and james do you live on here?
ppl check out this element song video... look out for silicon. funny

James, you can use the internet for research as long as your answer is in your own words and answers the question.
ReplyDeleteGood job to those of you who have answered so far!
a) The invention of the microscope is attributed to Zacharias Janssen, who developed it in 1590.
ReplyDeleteb) Advances in technology enable new discoveries to be made which were previously unknown, due to the better access to information through the use of technology. When the microscope was made available for use by scientists a whole score of objects unseeable by the naked human eye, for example bacteria, were exposed to the world. This led to research into bacterial properties, which has been built upon by countless scientists throughout history. Without the microscope, this scientific knowledge would not have been discovered.

a) Name an example of a technology or invention developed by scientists.
ReplyDeleteAntibiotics (Alexander Fleming).
b) Explain how an advance in technology has increased scientific knowledge.
As technology has advanced, so has scientific knowledge. The microscope and the telescope for instance. Without these two inventions, many scientific discoveries would remain undiscovered
A. the invention of the first chemical battery was made by an Italian physicist, named Alessandro Volta, in 1800.
ReplyDeleteB. As technology has advanced, scientific knowledge as devloped in ways that couldn't have been achieved without this new technology.
with the invention of the battery, an easier understanding of how energy can be converted into other types of energy was maintained and used for the benifits of society.

a. The invertion i choose was the light bulb
ReplyDeleteb. The advance in technology for the light bulb is now you can get a energy saver light bulb which savers power. Michael Bayeh
a) Samuel F. B. Morse invented Morse Code and lightning wires.
ReplyDeleteb)As more inventions are created, the scientific knowledge of our universe increases. For example, the telescope has given us a visual of what is out there in the universe, it has helped us determine many aspects and details of space.
Morse Code has helped us as it is always an efficent and dependable source of telecomunications when modern technology fails us.

lol, is it just me or is the quote of the week actually funny? :P
ReplyDeleteGotta love Einstein
a. Galilo, in 1609, was the first person to invent the telescope which he used in he astronomical discoveries.
ReplyDeleteb. the advance in technology has increased scientific knowlege as it has confirmed and denied many theories and also helps create new ones.
Tracy Leong
a) lightbulb
ReplyDeleteb) with advances in technology scientific knowledge has increased with materials becoming smaller and more advanced. for example, computers- used to take up a large space and were slow. today computers are small and fast.

ReplyDeletea. antibiotics
ReplyDeleteb. advancements in technology has boosted the accuracy and knowledge obtained through scientific research and experiments. if it weren't for technology advancements the human race would be no where near where it is today
a) Light Bulb
ReplyDeleteb) The light bulbs are now more smaller and brighter, for example, a hard drive in the olden days were big, heavy and took ages to transfer data, now they are smaller with a much larger capacity, lighter and 5X faster transfer rate, light bulbs before were bigger and less powerful, now they are smaller and more powerful, not to mention more efficient also.
Joseph Foti
God these questions get my heart pounding!
ReplyDeletea) THE LIGHT BULB
b) if technology did not develop, we wouldn't have a blog ;)
a) Name an example of a technology or invention developed by scientists. (1 mark)
ReplyDeletepenicillian
b) Explain how an advance in technology has increased scientific knowledge. (2 marks)
With increases in technology scientists are able to see and discover more. the differences in telescopes have allowed scientists to see further away and discover more.

a)PLASTIC!!! first invented by Leo Baekeland who was a Belgium chemist living in New York.
ReplyDeleteb)I think advance in technology has increased scientific knowledge because now we can acknowledge new inventions from different parts of the world and have more accuracy in measuring....stuff...(O.o;)
lol~ Soro Lee
a) The telephone was invented in the 1870s by Alexander Graham Bell and Elisha Gray. It is used as a device for communication.
ReplyDeleteb)An advance in technology has created a real stepping stone for scientists in the 21st century, making it more faster and conveniant to obtain information from primary sources. For example, if a soil sample were taken out in the 21st century, it would be observed and and measured in a matter of days. Technology is still expanding, helping scientists in all fields.
-Shant. Sorry bout the name ;) i do like cars
a) Name an example of a technology or invention developed by scientists. (1 mark)
ReplyDeletePenicilin discovered by Alexander Fleming in 1928.
b) Explain how an advance in technology has increased scientific knowledge. (2 marks)
An advance in technology has increased scientific knowledge because with the technology, scientists are able to measure and observe more accurately and conveniantly.
A) Bifocals
ReplyDeleteThere is no certainty who invented the glasses. But we do know that they were made from quartz and were usually set in bone. Once it was discovered how to make glass without air bubbles it was used insead of quartz. Then in the 1780's, Benjamin Franklin was annoyed with having to canstantly change glasses for different things. He then had his reading glasses cut in half and fused with his distance glasses. These are now called bifocals.
B) Through the advances in science, we as human beings have beeen able to get a better understanding of many different thing and have been able to prove or deny theories.And with this we have made advances in both medicine and technology.
i agree with monique. the quotes of the week are pretty funny :D
ReplyDeletebut moving on to the actual questions.
a) Name an example of a technology or invention developed by scientists. (1 mark)
Scientist Hans Jassen and his son Zacharias are believed to have invented a microscope (20x magnification) somewhere between 1590 and 1610.
b) Explain how an advance in technology has increased scientific knowledge. (2 marks)
Advances in technology have increased scientific knowledge because access to better equipment lets us see where we were unable to see before. Microscopes allow us to see even the tiniest particle, vastly expanding our knowledge of cells, single-celled organisms and bacteria. Telescopes are another technology that increases our scientific knowledge, letting us see into outer space.
Also equipment helps us investigate things on a smaller scale. A light box helps us replicate the effects of light on prisms and ticker timers (the very best invention ever made – just ask Sir) show speed and acceleration, allowing us to investigate easier.

a) Name an example of a technology or invention developed by scientists.
ReplyDeletetelephone
b) Explain how an advance in technology has increased scientific knowledge.
Since this was invented we now have mobile phones as well. these have made communicating with poeple easy and convenient.
microscope
ReplyDeletescientific knowledge has been increased with the advancement of technology. the better the technology the more information and accuracy is available to increase scientific knowledge. take the microscope as an example, from it's primitive form when it was first invented, there was only a small magnification.with the advancement of technology it can magnify alot closer,to a cellular level. this has given scientists the vision to explore specimens to new depths and increase scientific knowledge.
a) Name an example of a technology or invention developed by scientists.
ReplyDeleteAntibiotics (Alexander Fleming).
b) Explain how an advance in technology has increased scientific knowledge.
As technology has advanced, so has scientific knowledge. The microscope and the telescope for instance. Without these two inventions, many scientific discoveries would remain undiscovered
a) x-rays
ReplyDeleteb)the advance of technology has increased scientific knowledge and impacted our society to a great extent. results and information are now delivered more accurately. although initially made by accident, we have benefited from x rays immensely. over time, as x ray machines modified and improved, so did the scientific knowledge. x ray machines are now used heavily medical procedures.

(sir. emmas not on the blog so it wouldnt let her post it. this is her response.)
ReplyDeleteA) Radar- Heinrich Hertz
B) It has advanced technology by allowing scientist to map objects such as the surface of planets, detect objects at a distance, such as things underground. helping to detect earthquakes, look into ice caps that might give us information on climate change and exploring our solar system
Emma Muzzatti
a) in 1609, Galilo invented the telescope; he used this for his atstronomical discoveries
ReplyDeleteb) the telescope has advanced quite a lot from 1609, it helps to prove theories and cross out others, it has increased scientific discovries and made many many discovries.
apologies for my spelling mistakes ^^
ReplyDeletediscoveries**
The X-Ray was first discovered by Wilhelm Conrad Röntgen on the 8th of November 1895
ReplyDeleteThis helped advance current science because X-Rays allow people to view the internal anatomy of humans and animals alike, also useful for medical purposes
a) The Light Bulb b) has increased scientific knowledge as scientists can now experiment with light. This could be done before but the light bulb meant that a reliable source was now available. It also has been used in the advancement of research into energy transfer (e.g. From electrical energy to light energy with as little resulting heat energy as possible.
ReplyDeletePaul Harrison
Good answers by most.
ReplyDeleteThe answer to question a) required only a one word answer to get full marks. Most of you have done this well.
The answer to question b) is a little more tricky. When you are answering questions like this you MUST pay close attention to what the question is asking for. In this case the question was asking for you to show how an advance in technology has increased our knowledge.
The people who answered with microscopes did a very good job of this question and would have got full marks. Have a read through their answers. They were able to link the advancement (microscope) to an increased knowledge. (better understanding of cells, etc...)
Good work. Answering exactly what the question asks for is the key to getting full marks.
