Grade 7

Module 6


  1. Read the passage and answer the questions that follow.


We all know the story of Beauty and the Beast. In this story we learn of Maurice, Beauty's father who was an inventor and how he invented a machine to chop wood. The people of the town thought he was crazy. Why is it that all inventors seem to be crazy in the eyes of the people around them? I think the reason for this is that these people are way ahead of their time. These people think of making the impossible possible.

One of man's greatest inventions is a piece of wood shaded like a circle. Yes, the wheel. Who invented the wheel? History has it that the wheel may have been invented by the Sumerians, the same people who gave us the first written language? All we know is that it existed in ancient Mesopotamia and that without it we would not have the machines we have today. Through the ages the wheel was improved. Leonardo da Vinci, the Italian painter and inventor who lived about 500 years ago, improved the wheel further by making it lighter and stronger than before. Although the wheel in itself is not a machine, it becomes one when you combine it with an axle or another wheel. During the 19th century new wheels came into use and caused the big Industrial Revolution. We saw the invention of the steam engine. Today we cannot imagine our world without a wheel.

The wheel is used in basically every machine we can think of — in mother's washing machine, inside a modern jet airplane and even in the gyroscope, which plays an important role in guiding space flight.

Research: Wonderful World of Knowledge

  1. Answer the following questions in full sentences:
  1. How did Maurice spend his extra time?
  2. Did the people of his town accept Maurice? Say why.
  3. Why are inventors different to the people around them?
  4. What is regarded as one of the greatest inventions?
  5. When was the wheel invented?
  6. When was the steam engine invented and what was the result of the invention?
  7. Describe what the world would be like without the wheel.
  8. Give the opposite of the following:




  1. What is a gyroscope?
  2. Give a few examples where you know the wheel is irreplaceable.
LO 3.1.4

Using the extract and your imagination, sketch what you think the first wheel looked like.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
for screen printed electrodes ?

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world
