We are currently wrapping up our science unit on Chemistry. Students have learned about how various matter can be classified. We have touched on concepts including pure substances, mechanical mixtures, suspensions, solutions, methods use to separate mixtures, concentration, solubility and acidity. Today students participated in a science experiment where they used litmus paper to determine whether 4 mystery solutions were an acid or a base. They also observed a mystery mixture and had to classify the type of mixture, as well as, how they would separate the mixture. Check out the students hard at work!
