Comenius project: Why is water precious?


1. Stack lumps of sugar on a petrol dish.
2. Pour 15 ml of colf water on the bottom of the dish
3. Use a timer and find out how long does it take the "sugar tower" to fall down.
4. Do the same thing with hot water from the tap.

What did we learn?

The hotter the water the more easier sugar dissolves in it.

Cold water - and the tower holds

Cold water and the tower has fallen in 6 min 11 sek

Hot water and almost there...

Tower in hot water fell down in 3 min 33,8 sek
Tower in a hot water - another group's result
