Recently in chemistry we have discussed radioactivity and classifications of matter. We took a test on Tuesday on the classification of matter unit which consisted of homogeneous and heterogeneous substances etc. Later this week we then had a mini lab on the rate of which our dear friend Frosty the Snowman melted. This taught us about the linear relationships of graphs and that data pools help scientists have more precise data collections and answers. We also did a lab about radioactivity and half lives that used the candy skittles. This helped me learn that you cannot predict the exact time an atom will decay but you can make an educated guess. Next the class is planning on going further into the study of radioactivity. I think this will be interesting because it will deal with the elements individual since no characteristics of these elements are the same.
