By these means he found out what quantity of water was equal to a certain weight of silver. The mass being then taken out, he poured in by measure as much water as was required to fill the vase once more to the brim. ![]() Having prepared them, he filled a large vase with water up to the brim, wherein he placed the mass of silver, which caused as much water to run out as was equal to the bulk thereof. Whence, catching at the method to be adopted for the solution of the proposition, he immediately followed it up, leapt out of the vessel in joy, and, returning home naked, cried out with a loud voice that he had found that of which he was in search, for he continued exclaiming, in Greek, eurhka, (I have found it out).Īfter this, he is said to have taken two masses, each of a weight equal to that of the crown, one of them of gold and the other of silver. Charged with this commission, he by chance went to a bath, and being in the vessel, perceived that, as his body became immersed, the water ran out of the vessel. He, in due time, presented the work to the king, beautifully wrought, and the weight appeared to correspond with that of the gold which had been assigned for it.īut a report having been circulated, that some of the gold had been abstracted, and that the deficiency thus caused had been supplied with silver, Hiero was indignant at the fraud, and, unacquainted with the method by which the theft might be detected, requested Archimedes would undertake to give it his attention. Hiero, when he obtained the regal power in Syracuse, having, on the fortunate turn of his affairs, decreed a votive crown of gold to be placed in a certain temple to the immortal gods, commanded it to be made of great value, and assigned an appropriate weight of gold to the manufacturer. Though Archimedes discovered many curious matters which evince great intelligence, that which I am about to mention is the most extraordinary. And while they were anointing of him with oils and sweet savors, with his figures he drew lines upon his naked body, so far was he taken from himself, and brought into ecstasy or trance, w ith the delight he had in the study of geometry. * Chalkface Lovesongs is broadcast on Radio 4 on Sundays at 5.40pm, starting on February 9, and repeated the following Saturdays at 7.45pm.Jacquie Buttriss reads her story on February 9 (repeated February 14).Often times Archimedes’ servants got him against his will to the baths, to wash and anoint him, and yet being there, he would ever be drawing out of the geometrical figures, even in the very embers of the chimney. The more stones we put in the bath, the more the weight of the stones made the water leak, imperceptibly, out of the tiny split. The children’s observations skills were spot on. There was a tiny, hairline crack in the side. My assistant’s smile broadened as she stood up and pointed to the side of the bowl. “The water’s gone down,” said one, knowingly. The children crowded in to see for themselves. “Right, stand back everybody and we’ll see how much the water has gone.” I looked at the line. So, we tried again, placing the two biggest Mr Archimedes stones in the bath, followed by the two biggest Kangaroos, Goats and Wombats. “Right everybody, stop what you’re doing, find your pebbles and come over here to join in.” I thought that if it didn’t work with one set of stones, it was sure to work with two, or maybe three. ![]() My assistant and I exchanged bemused glances and the children asked, predictably, “Can we do it again?” There was no discernible difference and I had to admit that the water was still at the original level marker. Finally, the level of the water was measured. ![]() Then each of the other characters - Kangaroo, Goat and Wombat - was carefully placed in the tub. We used stones for my lessons, which we painted as the book’s characters.įirst, the Mr Archimedes stone was put into the bath. Mr Archimedes decides it is time to find out who the culprit is, so they all take turns getting in and out of the bath and Mr Archimedes measures the water. The problem is that, whenever they have a bath together, the water always overflows. In the book, Mr Archimedes has a bath with three of his friends - Kangaroo, Wombat and Goat. We then went through the story - I decided to use Mr Archimedes’ Bath, by Pamela Allen. The first group gathered around the table and the children took turns to pour water into the bath, about two-thirds of the way up the side. One of these key scientific concepts was displacement and I wanted to focus on Archimedes’ principle. I was teaching five and six-year-olds and wanted to do a sequence of lessons about the properties of water - evaporation, condensation and dissolving. ![]() By Jacquie Buttriss, retired primary teacher
