    • Chemical change by LiamIf you do certain things to chemicals, certain reactions will happen
    • IntroductionThis is an experiment about Modification.Modification means changing, e.g. if I had an apple and I peeled it, Ihave changed the way my apple looks. I have modified it.
    • What my experiment isMy experiment is to melt sugar and turn it into carbon.Sugar is a white crystal, it comes from a plant called sugar cane. Sugar is sweet and crunchy, a little bit of sugar is fine but a lot can be unhealthy. It is surprising that something from a plant can be unhealthy.Carbon is in coal, oil and in plants. It can be solid and it is black.
    • My prediction of what happensI think that the sugar will start to melt and then dry up after I’ve heated it.
    • Materials One teaspoon of sugar A small pot A stove
    • method1. Put one teaspoon of sugar into a large pot and spread evenly over the bottom of the pot. One millimetre is ideal.2. Put the pot on low heat, the sugar will start to melt and turn to liquid.3. Slowly it will start to blacken and harden.4. This is carbon.
    • Observation1. The sugar started to melt.2. It started to go toffee colour3. Slowly it went solid and black and turn into carbon
    • Why it happenedWhen the sugar turned to liquid the heat made the sugar dry up.I kept heating the sugar after it dried up and that’s when it turnedto carbon.
