Dissolving
http://www.digitalbrain.com/digitalbrain/public/subjects/1.%20primary/ks2sci/su3/mod4/exercise2.db_psc Water is an important solvent; other substances dissolve in it to form solutions. Many substances are water soluble - they dissolve in water to form new substances. If you add salt to water, it will dissolve, disappearing and turning into a salt solution. Not everything will dissolve in water- you can try an experiment to find out what will and what won't dissolve in task 1. If something will not dissolve in water it might dissolve in another liquid, like alcohol for example. Oily substances tend not to dissolve- this is one reason why we have to add washing up liquid to our water to get grease off our plates! |

Dissolving - 4learning
http://www.channel4.com/science/index.html Solids do not disappear when they dissolve in a liquid. You can get them back by evaporating the liquid away, leaving the solid behind. When a solid dissolves, tiny bits of it come off and become part of the liquid. How quickly a solid dissolves depends on what you do to it. |

More about dissolving (6c)
http://www.standards.dfes.gov.uk/schemes2/science/sci6c/?view=get This unit consolidates and extends children's understanding of what happens when a variety of solids dissolve. Experimental and investigative work focuses on: -making and testing predictions -planning a fair test -repeating observations and measurements and evaluating these -representing data in line graphs and interpreting what these show. Work in this unit also offers opportunities for relating understanding of dissolving to everyday contexts. This unit takes approximately 12 hours. |
