510 REPORTS ON THE STATE OF SCIENCE. 



co-ordinated with the teaching of domestic science and the former should 

 be so taught as to provide an intellectual as well as a manual training. 



(12) It is important that inspectors of schools should possess an 

 adequate knowledge of the subject-matter and methods of instruction in 

 elementary science. 



APPENDIX A. 



Si/Uabns of Work in Elementary Experimental Science. 



Note. — It is assumed that in their arithmetic lessons the pupils have acquired skill in the 

 measurement of lengths and areas and have through these exercises obtained a real 

 knowledge of the manipulation of numbers in the decimal system not involving the 

 use of more than two digits after the decimal point. 



Syllabus for Boys' Schools, First Fear {about 11 to 12 years of aye). 



The measurement of volume of a rectangular block of wood. The reason for 

 selecting the cube as the unit for measuring volume and capacity ; explanation of 

 therrule for calculating volume of a rectangular solid — a means of counting the 

 number of unit cubes that will build up the solid. 



Cut out of turnip, soap, clay, &c., cubes of one inch and one centimetre edge. 

 To make a lioUow cube of cardboard of one decimetre edge, the volume of which 

 is the litre, containing 1 ,000 cubic centimetres. Mould some putty or plasticine into 

 rectangular shape, and determine its volume by measurement ; distort it, and lead 

 class to see it still occupies the same amount of space, and may still be measured 

 in rectangular units. 



The volume of rectangular blocks of wood (including cubes) in cubic inches 

 and cubic centimetres; the number of cubic centimetres in a cubic inch. 



The graduated cylinder ; the fluid ounce and measuring glass ; the number of 

 cubic centimetres in a fluid ounce ; fill a water-tight rectangular box with water, 

 and pour into gr.iduated cylinder; compare volume by direct measurement and 

 by graduated cylinder; the limits of accuracy in using the graduated cylinder. 

 Volume of small bodies by displacement in graduated cylinder. 



The burette — a more finely divided graduated cylinder. Volume of small 

 bodies such as pencils, glass rod, nails, by displacement in burette. The pipette — 

 its method of use. Direct measurement of capacity of a bottle by burette and 

 pipette. 



First notions of force and weight — the measurement of a pull or push ; the 

 force of gravity very simply treated. Equal weights defined as those that stretch 

 a spiral spring or an elastic cord to an equal extent ; construction of a series of 

 bags of sand or shot of equal weight. 



Experiments with a simple lever or seesaw ; equal weights balance at equal 

 distances from the turning edge. 



British and metric units of weight and capacity ; the gallon and its sub- 

 divisions ; a gallon of water weighs ten pounds. To weigh cubes of diflferent 

 kinds of wood on the seesaw. 



The balance, adjustment and use ; weight of cubes of wood, determined to 

 j^jf gram. 



Weight of volumes of water (30, 40, 50 c.c, &c.), measured from burette and 

 pipette, leading to the fact that one cubic centimetre of water weighs one gram. 

 Repeat these experiments with hot and lukewarm water. 



Weigh volumes of milk, spirit, brine, mercury, &c., measured from burette, and 

 to calculate the weight of 1 c.c. of each. 



Find the weight of 1 c.c. of milk, skimmed milk, cream, and mixtures of 

 fresh milk and water. Measurement of amount of cream in milk by allowing 

 100 c.c. of fresh milk to stand for some hours in graduated cylinder.
