## Freehand drawing

Freehand drawing

Now we are going to see how well you are able to draw without geometry instruments. This is called FREEHAND DRAWING. Use a sharp HB pencil for each of the following assignments.

Are you left-handed or right-handed?

## [lo 1.3]

Draw parallel diagonal lines in each frame. Indicate the direction in which you draw the lines most easily with an arrow.

Interesting:

Is there any resemblance in which direction right-handed and left-handed learners find it the easiest to draw the lines?

## [lo 1.3]

Draw parallel horizontal lines in each frame. Also indicate the direction in which you draw the lines most easily, with an arrow.

Interesting:

Is there any resemblance in the direction in which left-handed learners draw the lines the most easily?

## [lo 1.3]

Draw parallel vertical lines in each frame. Indicate with an arrow the direction in which you draw the lines most easily.

Interesting:

How do most right-handed learners draw the lines most easily?

How do most left-handed learners draw the lines most easily?

Background:

Once you are able to draw horizontal and vertical lines, you must try to draw RIGHT ANGLES.

## [lo 1.3]

Begin by drawing a vertical line and then draw a horizontal line at one of the points so that a right angle is formed. Draw fast and keep moving your hand while supporting it with the little finger if necessary. See how many right angles you are able to draw in a minute.

Background:

If you are capable of drawing right angles, you will be able to join right angles in order to form SQUARES, RECTANGLES and TRIANGLES.

If you draw a line, think only of its direction. Another line will determine its length.

## [lo 1.3]

Draw at least five squares of different sizes. (Experiment with the sequence in which you draw the sides by numbering the sides. Which way do you find the easiest? Circle it.)

## [lo 1.3]

Draw at least five rectangles of different sizes. (Experiment with the sequence in which you draw the sides by numbering the sides. Which way do you find the easiest? Circle it.)

## [lo 1.3]

Draw at least five triangles of different sizes. Experiment with the size of the angles.

Background:

The above-mentioned exercise is very important, since most of the objects that you will want to draw can be simplified and drawn as basic geometric figures. Therefore, in drawing a specific object you can use the geometric figures to form the framework.

Make a drawing of an object such as an animal by using an oval that developed from a rectangle

Let us practise drawing an oval or a circle with the aid of a square or a rectangle.

INSTRUCTIONS FOR A CIRCLE :

1. Draw a square as in Assignment 5A.
2. Mark half of each side with a small mark.
3. Join the marks with a slight curve in order to form a circle.
4. Draw the circle with a dark pencil.
5. Erase the lines of the square carefully.

## [lo 1.3]

Draw at least three circles of different sizes by following the above-mentioned instructions.

where we get a research paper on Nano chemistry....?
what are the products of Nano chemistry?
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..

Even nanotechnology is pretty much all about chemistry... Its the chemistry on quantum or atomic level

no nanotechnology is also a part of physics and maths it requires angle formulas and some pressure regarding concepts

I only see partial conversation and what's the question here!
what about nanotechnology for water purification
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
Professor
I think
Professor
Nasa has use it in the 60's, copper as water purification in the moon travel.

what is the stm
is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
Damian
How we are making nano material?
what is a peer
What is meant by 'nano scale'?
What is STMs full form?
LITNING
scanning tunneling microscope
Sahil
how nano science is used for hydrophobicity
Santosh
Do u think that Graphene and Fullrene fiber can be used to make Air Plane body structure the lightest and strongest. Rafiq
Rafiq
what is differents between GO and RGO?
Mahi
what is simplest way to understand the applications of nano robots used to detect the cancer affected cell of human body.? How this robot is carried to required site of body cell.? what will be the carrier material and how can be detected that correct delivery of drug is done Rafiq
Rafiq
if virus is killing to make ARTIFICIAL DNA OF GRAPHENE FOR KILLED THE VIRUS .THIS IS OUR ASSUMPTION
Anam
analytical skills graphene is prepared to kill any type viruses .
Anam
Any one who tell me about Preparation and application of Nanomaterial for drug Delivery
Hafiz
what is Nano technology ?
write examples of Nano molecule?
Bob
The nanotechnology is as new science, to scale nanometric
brayan
nanotechnology is the study, desing, synthesis, manipulation and application of materials and functional systems through control of matter at nanoscale
Damian
Is there any normative that regulates the use of silver nanoparticles?
what king of growth are you checking .?
Renato
What fields keep nano created devices from performing or assimulating ? Magnetic fields ? Are do they assimilate ?
why we need to study biomolecules, molecular biology in nanotechnology?
?
Kyle
yes I'm doing my masters in nanotechnology, we are being studying all these domains as well..
why?
what school?
Kyle
biomolecules are e building blocks of every organics and inorganic materials.
Joe
how did you get the value of 2000N.What calculations are needed to arrive at it
