9. Concept of Energy and Power; (a) Concept of Energy and power. (b) Definitions: (i) power (ii) energy (iii) units (c) relationship between energy and power
10. Revision
11. Examination.
WEEK: ONE
DATE:
TOPIC: Revision of last term’s work
The Teacher should use discretion, knowing areas most students are still having difficulties in last term’s work and re-teach or re-explain those areas within this week.
WEEK: TWO
DATE:……………………………..
TOPIC: Board Practice
SUB-TOPICS:
(i) The instrument required for a good board practice
(ii) Setting Drawing Paper on the Board
(iii) Sharpening pencil to conical point and knife edge
(iv) Using the tee and set squares for drawing boarder lines and other horizontal and vertical lines
(v) Positioning and drawing the title block.
(vi) Writing (freehand) legible letters and numerals
Content Development (NOTES FOR FIRST LESSON/PERIOD ONE)
Sub-Topic I: The instruments required for good board practice
The instruments required for good board practice are:
(1) Drawing board and Tee-square
(2) Set-square (30o, 60o , 45o angles)
(3) Compass and Dividers
(4) Protractor and French curves
(5) Drawing pencils (HB and 2H)
(6) Eraser and Drawing paper
Sub-Topic II: Setting Drawing Paper on the Board
Step 1: The drawing board is conveniently placed on the table with the paper on the board, leaving equal size all round, with the Tee-square edge to the left hand side.
Step 2: Place the tee-square on the paper and gently move or slide the tee-square to the top edge of the paper. Set the top edge of the paper parallel to the edge of the tee-square with the stock of the tee-square firmly against the edge of the drawing board on the left-hand side.
Step 3: Hold the paper with four pieces of adhesive tape or two metal cups to hold the paper in position at four corners.
Step 4: Gently slide the tee-square down without moving the paper.
Sub-Topic III: Sharpening of Drawing Pencils to conical point and knife edge
A well sharpened pencil is very essential to technical drawing. Pencils for lettering and freehand sketching should be sharpened to a ‘conical point’ while those for geometrical or engineering drawing should be sharpened to a ‘chisel point’.
All horizontal lines are drawn with the aid of tee-square. The set-square is used sitting squarely on the tee-square to draw vertical lines.
EVALUATION
1. Briefly explain how set-square can be used to draw vertical lines.
2. Mention five drawing instruments.
Content Development (NOTES FOR SECOND LESSON/PERIOD TWO)
Sub-Topic IV: Using the tee and set squares for drawing Lines
This is a practical topic. The teacher should DEMONSTRATE this as much as possible in class for the students
The various uses of setsquares are given below…
