Gr 5-6 Acid or a Base? Understanding the pH Scale

Why does acid rain eat away at limestone and marble? How come most cleaning products contain a base? Answer these questions and more as we explore the pH scale. Students will have a chance to observe hands-on experiments and determine for themselves if each mystery solution is an acid or a base. During our discussion, we will also cover what constitutes an acid and base and characteristics of each.


Program format
1.) This program will begin with a discussion of different types of drinks that the students enjoy

2.) After our discussion, we will talk about how most of these drinks are acidic while others are basic

3.) We will review the vocabulary necessary to understanding the lesson

4.) Students will watch a short video on the pH scale: what it is and the various ways we can test pH

5.) In our first activity, students will be presented with 6 “mystery” liquids which they will try to identify and then determine whether they are an acid, a base, or neutral

6.) Once the identity of the 6 liquids is revealed, students will learn about how acids and bases play a role in our everyday lives

7.) In our second activity, we will discuss how acids and bases are formed, and whether each solution presented would have more hydronium ions, hydroxide ions, or an equal amount
