At this stage the solution becomes saturated. Now start heating the water. You will observe that more sugar starts dissolving in water. After dissolving more sugar start to cool the water. You will see sugar crystallized at the bottom of the glass once the water cools down. Note down all the changes that occurred during this process and classify them into different categories.

1. Cut a piece of paper in four square pieces. Cut each square piece further into four square pieces. Keep these pieces on the floor or a table so that the pieces acquire the shape of the original piece of paper.Can you join the pieces back to make the original piece? Is there a change in the property of the paper? 2.Group students to play this game: a) Let one name a common process (eg: rusting of iron) b) The other will decide if it is a physical or chemical change. The second student an now pick another and name another process. continue...
