There is a //physical change// going on here though. Since each Ipod Nano is made up of the same metal (aluminum) and they don't change into a different substance, this is obviously a physical change. Plus, the fact that the color of each Ipod Nano changes supports the idea that this is an example of a physical change. Also, there might be scratches on one, but not another. These are both facts that lead you to believe that this is an example of of a physical property and change. || || Photosynthesis is a //chemical property// that is used by plants.

As we all know, plants come in contact with sunlight all the time. When the rays from the sun come in contact with the leaves of a plant, those rays of sunlight are converted into sugar through a special process. This process is called photosynthesis. The sunlight is converted into sugar (energy used by the plant), which is then used to produce oxygen or fruits. Since a plant converts the sunlight into sugars, a totally different material, this is an example of a //chemical change//. ||
