1. USING THE SCIENCE OF COMPUTATION CONSTRUCTION/ AGRISCIENCE/TECHNOLOGY

2. AREAS OF COMPUTATION IN AGRISCIENCE MEASUREMENT : Involves determining the number of units in something; a foot is 12 inches long or a bushel of shelled corn is always 56 pounds. MATHEMATICS : Involves the use of numbers and symbols to show relationships. Made up of two areas- skills and applications

3. WHY STANDARDS OF MEASUREMENT ? Buyers and sellers must have the same standard when trading. Persons mixing chemicals need to use the same standard that is given in the mixing instructions. People who make products need to use the same standards.

4. MEASUREMENT SYSTEMS CUSTOMARY SYSTEM -Inch, foot, yard, mile, ounce, pound, quart, pint, gallon and acre are examples. METRIC SYSTEM - Grams, meters, liters are examples. Based on decimal system that increases or decreases by numbers by 10s. Uses prefix (“centi”) to meter to form centimeter (1/100 of a meter)

5. LINEAR MEASUREMENT IT IS THE DISTANCE BETWEEN TWO POINTS. EXAMPLES : 1 FOOT = 12 INCHES 1 YARD = 3 FEET OR 36 INCHES 1 MILE = 5,280 FEET

6. AREA IT IS THE MEASUREMENT OF SURFACES EXAMPLES : LAND FLOOR SPACE IN A GREENHOUSE REPORTED IN SQUARE FEET OR SQUARE METERS

7. VOLUME IT IS THE TOTAL SIZE OF AN OBJECT. IT IS THE TOTAL AMOUNT OF SPACE SOMETHING TAKES OR HOLDS. RECORDED IN CUBIC FEET OR CUBIC METERS

8. WEIGHT WEIGHT IS THE HEAVINESS OF SOMETHING; RELATED TO GRAVITY WHICH IS THE PULL OF THE EARTH. MEASURED IN POUNDS OR MASS IN KILOGRAMS

9. INSTRUMENTS USED IN LINEAR MEASUREMENTS MEASURING STICKS TAPE MEASURES CHAINS CALIPERS REMOTE MEASUREMENT THICKNESS GAUGE

10. USE OF FIVE MAIN SHAPES IN CONSTRUCTION SQUARE: AREA=L X W RECTANGLE : A = L X W TRIANGLE : A = B X H DIVIDED BY 2 TRAPEZOID : A = B + B DIVIDED BY 2 X H CIRCLE : R SQUARED X 3.14

11. LAND AREA CUSTOMARY UNIT IS THE ACRE ONE ACRE IS : APPROXIAMATELY 210 FT BY 210 FT. OR 43,560 SQ. FT. METRIC UNIT IS THE HECTARE A HECTARE IS 2.47 ACRES OR 107,639 SQ. FT.

12. VOLUME VOLUME IS THE AMOUNT OF SPACE SOMETHING OCCUPIES. MEASURED IN CUBIC UNITS

13. WAYS OF SELLING TIMBER BOARD FOOT : A piece of wood one foot square and one inch thick. CORD : Pulpwood or firewood is usually sold this way. A stack 4 feet wide by 4 feet high by 8 feet long or 128 cubic feet is one cord A cord of wood also weighs 5300 lbs.
