6R: Acid and Alkali Testing

In our science lesson today, we learned how to test for acids and alkali. We used universal indicator paper to identify the ph level. A real hands on piece of learning. We also talked about independent and dependent variables, and whether we thought an acid, alkali or neutral substance would make a better cleaner. The children were reminded that although the chemicals we were using are safe, some chemicals can be dangerous and good scientists will  treat them with caution.
