Alien Juice Bar - Acids and Bases

The Alien Juice Bar tutorial provides a simple and fun way to introduce the characteristics of Acids and Bases including the concepts of pH, pOH, neutralization.

Whether students are killing off aliens by serving them acidic or basic drinks that their constitutions cannot deal with, or they are sorting drinks by their characteristics, students can learn or review the main points of acids and bases.  This tutorial created through UC Berkeley is simplistic enough for middle school while intriguing enough to capture the attention of most high school students.

There are three parts of the tutorial. Part one allows students to learn about pH and pOH by identifying them using cabbage juice.  Phase two allows students to determine which drinks are safe to serve aliens based upon the acidic or basic composition of the monster.  Aliens die when their pH levels are altered. The third phase guides students through the neutralization of pH by mixing acids and bases.

This tutorial is best used on an interactive white board (SMART Board) to involve the entire class in the process of protecting or destroying aliens with basic acidic knowledge.
