<p>In the seventies a pioneering science programme in India attempted to revitalise the learning of science in village schools which had no science labs. The shift was from the chalk-and-talk method to hands-on, on making things with simple humble material available in the village. The hunt was on for low-cost, locally available, affordable things to do science.<br /><br />Science of a matchbox<br />The matchbox surprisingly emerged as a STAR. Being mass produced in a factory the matchbox confirms to certain standard dimensions. The length of the matchbox is very close to 5 cm (2 inches) – a very good estimate of length. You could put six matchboxes back-to-back to make 30 cm (1 foot). The weight of the new matchbox is very close to 10 gm. Ten new matchsticks (not burnt) weigh about 1 gm and the weight of a single matchstick is very close to 0.1 gm.<br />Paint the matchbox drawer with some oil to make it water proof. Fill it with water and the drawer holds roughly 20 ml of water. Pour out 5 drawers of water in a bottle to make 100 ml. The humble matchbox becomes a good measure for volume. <br />So, using a universally available matchbox, you can get a good feel of length, weight and volume — all very basic entities of any science curriculum!<br /><br />Matchbox train<br />Of course, you make many simple toys with matchboxes. For instance, the zero-cost Matchbox Rider which is made by threading an old matchbox in an ingenious way. Make four holes and then weave a 1.5-metre long thread at a slant in the matchbox. Tie a knot on the ends. Hold the string in both hands as shown. Turn and twist the left hand rapidly. The matchbox will travel along the string track. You can stick a picture of a rabbit to make the toy more interesting. <br />Watch video http://www.youtube. com/watch?v=g7Rcf9Soqfg<br /><br />Matchstick models<br />Take two matchsticks, scrape the sulphur and push them in a piece of black cycle-valve tube to make a universal joint of two. With more sticks and tubes make scores of 2-D shapes – triangle, square, hexagon etc. The square when pressed will bend and become a kite-shaped rhombus. All other shapes will wobble and shake but not the triangle – it will not budge. Of all the polygons, the triangle emerges as the strongest structure. No wonder triangles are used to construct roof trusses, bridges and huge microwave towers. You can also build 3-D structures like tetrahedrons, prisms, cubes and icosahedrons. With these basic modules you can make many more structures.

Fix two paper clips on the outer shell of an empty matchbox and weave a 1-metre long thread through them. Tie fat knots on the ends of the thread. There should be very little gap between the clip and the matchbox edge. Place the matchbox drawer in its shell. Hold the thread tight and let the matchbox go. The matchbox will fall in short funny jerks. You can slow the fall by pulling the draw out and speed it up by pushing it in. <br />Watch video http://www.youtube. com/watch?v=OHOb--hfiQU<br /><em><br />(The writer is an award-winning science teacher and founder of toysfromtrash.com)<br /></em><br />A matchbox teaser<em><br /><br /></em>How many things can you fit in a matchbox? 20.... 30.... 100?
