Hey it's 59M. I'm just here to tell you some things I learned in science class for this chapter. I learned that a solution is something made up of more than one thing but only appears to be one thing. I also learned that melting is when something is changing from a liquid to a solid. I also learned about acids and bases and the pH scale. The thing I liked best about this chapter was testing things to see if it was an acid or a base. I thought it was really cool using an indicator and getting to put it in the acids and bases. I also liked making our own solutions and mixtures. My mixture was pretzels, peanuts, and cheerios. My solution was water with blue food coloring. My least favorite thig was all the study guides.=[ They are not fun. Now I have a question. Will someone give me some examples of pyhsical changes? Please leave a comment if you can. =] Thanks!
