MIXTURES OF MATERIALS How much will dissolve? Did you know that: that there is a limit to the mass of a solid that can dissolve in a given amount of water, and that this limit is different for different solids. Well, there is and this is what you need to remember from today’s sciencework.YOUR TASK Aim: to find out how much salt and sugar will dissolve in 60ml of water. (Copy down your aim in your science books).1. Predict how many small measuring spoons of salt/sugar willdissolve in 60ml of water. ( I think . . . . .small measuring spoons ofsalt/sugar will dissolve in 60ml of water ).2. Put 60ml of water in a transparent container.3. Add 1 small, level measuring spoon of salt/sugar to your water at atime. Record how many will dissolve.4. Draw a labelled diagram to show what you used and what you did.Remember, diagram in pencil, labels in pen.5. Under the heading Method write 4 sentences describing what youdid. Under the heading Results, write down what happened in yourexperiment. Under the heading Conclusions, write down what you found out. (Ifound out that the amount of salt that will dissolve in 60ml of wateris different/the same as the amount of sugar that will dissolve in60ml of water).Brain teasing questions 1. Using the results from the whole class, calculate the averagenumber of measuring spoons of salt that would dissolve in 60ml ofwater. Do the same for sugar.(Average = total number of measuring spoons divided by the number of groups). Recording sheet Aim We wanted to find out how much _ _ _ _ and _ _ _ _ _would dissolve in 60ml of _ _ _ _ _.Method We measured 60ml of water into a see through plastic _ _ _ . Next we added one small measuring _ _ _ _ _ ofsalt or sugar to see how much would _ _ _ _ _ _ _ _.Results We dissolved_________ measuring spoons of salt and_________ measuring spoons of sugar.Conclusions We found out that the amount of salt that would dissolvein 60ml of _ _ _ _ _ was *______________* the amountof sugar that would dissolve.Word Bank Salt *different to**the same as**less than*
