In this chapter I learned that an atom is the smallest you can break down a substance. I liked the expiriment when the cabbage juce turned the substances inside a bag purple and heat came from the bag. I didn't like all the powerpoints we did. I find them boaring. I also learned that cabbage juce is an indacator. I learned what an indicator is too. I still don't get how a solution is a mixture and how a mixture can't be a solution.
