Dissolving Sugar Cubes

water worked the best to dissolve the sugar cubes. hypothesis If a sugar cube is put in coke then it will dissolve the fastest because the coke has the closest molecular structure to the sugar cube. Procedure Set up the materials Pour liquid the independent variable into the cups up to the first

Sugars Cubes are great for exploring science concepts Absorption and Dissolving using coloured water. Children will have fun playing and experimenting with the coloured water and the effects this has on sugar cubes. This is a super simple science experiment for kids that is easy to set up and requires easy accessible items.

Put a sugar cube into the cold water and stir with the spoon until the sugar disappears. Repeat this process remembering to count the amount of sugar cubes you put into the water until the sugar stops dissolving, you are at this point when sugar starts to gather on the bottom of the glass rather than dissolving.

the sugar cube to dissolve Variables Independent variable Dependent variable Control variables temperature time it takes for all the sugar cube to dissolve same amount of water same type of sugar cubes same shaking Simple prediction The hotter the water, the less time it takes the sugar cube to dissolve. Quantitative prediction if possible

This means the finer the sugar particles, the faster it will dissolve. The sugar in the middle of a sugar cube is protected from the water by the sugar in the outer layers of the cube the water has to go through those outer layers first. But if you crush the cube into a powder, all of the sugar is exposed to the water at once.

If you leave the sugar cubes long enough, they will dissolve completely! Extension tasks. Design an investigation by thinking about how to make it a fair test. Think about the amount of water used, the number of cubes and the amount of material used to block the water. Perhaps you could time how long each cube tower takes to fall!

Include what you did and the time it took for the sugar cube to dissolve for each of the variables. 4. Suppose you wanted a sugar cube to dissolve as quickly as possible. Describe how you would do it. Use your results from 3 to support your answer. 5. If you carried out the experiment like you described in 4 above, how long

Bob needed to work out the average dissolving times for each of his sugars. He wrote down his working out for icing sugar like this average dissolving time 27 23 25 3 75 3 25 s a Work out the average dissolving times for the other two sugars. Show all your working out. b Write all three average dissolving times into your table.

A sugar cube is placed into a beaker of distilled water and allowed to dissolve.The initial mass is 107.20 g.

Step 2 Mix water with drops of food coloring, then allow students to carefully pour or use an eyedropper to add the colored water to the dish, just enough to touch the bottom of the sugar cube stack. Step 3 Make observations.Encourage students to watch as the colored water travels through the sugar cubes. Ask them to notice how the cubes absorb the water rising and gradually dissolve.
