Dear M.L. Taylor,<br /><br />Thank you very much for your message and sorry for my late answer!<br /><br />I suggest we can make a news out of your experience, and publishing your video there.<br /><br />Would you mind writing a paragraph about your experience, and sending it to me along with the video at this address: <a href='mailto: mathilde.bargoin@eun.org'>mathilde</a>?<br /><br />Thank you very much in advance,<br /><br />Kind regards,<br /><br />Mathilde

One of my students filmed our experiment and edited it into a quicktime video. Can we upload his video to share with other participants in the experiment?<br /><br />M.L. Taylor

Hola Araceli!<br /><br />Exactamente! <br /><br />S es la salinidad absoluta <br /><br />ms es la masa de sal restando del valor que hayas obtenido la masa inicial del plato<br /><br />y msw es la masa del agua salada.<br /><br />Muchas gracias para su participacion en el Experimento Global del Año Internacional de la Química!!<br /><br />Saludos,<br /><br />Mathilde

Hola a todos! <br /><br />Me llamo Araceli Mateo y soy profesora de química en una escuela secundaria<br /><br />Estamos por llevar a cabo la experiencia 2 sobre salinidad y quisieramos confirmar la fórmula para determinar la salinidad absoluta.<br /><br />En el teórico dice que S = ms: msw * 1000 (g:kg)<br /><br />S es salinidad absoluta<br />ms es la masa de la sal obtenida por diferencia de pesadas<br />msw es la masa del agua salada<br /><br />Es así? Por favor necesito la respuesta con urgencia<br /><br />Saludos<br /><br />Araceli desde Rosario (Argentina)

To conduct the experiment about Salinity, you will use:<br /><br />• Shallow glass or plastic dish or Petri dish (preferably clear to make it easy to see the salt).<br />• Cover for the dish that allows air circulation.<br />• Graduated measuring cylinder or jug.<br />• Balance that can weigh to 0.1 g with the capacity to weigh the dish and water<br /><br /><br />The activities of the Global Water Experiment are designed to be undertaken with equipment and materials commonly available in a school laboratory. However if preferred, a kit especially designed for carrying out the activities in the Global Water Experiment can be purchased from the Radmaste Centre at the University of Witwatersrand in South Africa: http://www.radmaste.org.za/. Adapted experimental protocols have been developed for these kits to ensure consistency with the Global Water experiment.<br /><br />The kit is supplied as a school resource with the common equipment and materials to perform the experiments and ten individual sets of equipment for student use (which can also be ordered individually). The price of the kit is about $US165 and does not include postage and packaging. The order form and the up-to-date prices can be found at:<br />http://www.radmaste.org.za/docs/RADMASTEorderform.pdf
