In order to dissolve something there needs to be two substances – a solute and a solvent: (A solute is a solid that dissolves and a solvent is the liquid it has dissolved in) Koolaid can be dissolved in water. Sugar can be dissolved in water. Instant coffee can be dissolved in water. A mixture called a solution is made when a solid disappears into a liquid. When the substance dissolves the solution is transparent. The solution could be of a colour. If it is not transparent (see-through), it is not a real solution. A solid solute dissolves in a solvent to make a mixture called a solution. In order to melt something you need only one substance: Chocolate melts in a fondue pot. Butter melts in a frying pan. Wax melts in a burning candle. Ice melts on a hot day.
Steps to be taken
1. Take some sugar and stir it into a jug of water. The granulated crystals dissolve and mix with the water. 2. Take an ice cube from the freezer and place it on a plate and take it outside on a hot day and watch it melt. 3. Try melting and dissolving some of the other items above or try some items that you may have around the house. Note: Make sure you have adult supervision it you burn a candle or melt butter or chocolate.
