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?

Assignment 1:

[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?

Assignment 2:

[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?

Assignment 3:

[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.

Assignment 4:

[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.

Assignment 5a:

[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.)

Assignment 5b:

[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.)

Assignment 5c:

[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.

Assignment 6a:

[lo 1.3]

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

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
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.
Tarell
what is the actual application of fullerenes nowadays?
Damian
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.

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.
