Introduction

It’s back to school and love seems to be in the air. Check out this fun way to learn about chemical reactions.

Objectives

To create a "potion" and learn about chemical reactions

Materials

• Clear plastic cup (five ounce approximately)
• Vinegar
• Baking soda
• Food coloring (optional)
• Dishwashing liquid (optional)
• Tablespoon (measurement does not have to be exact)
• Wooden craft stick (or something for stirring)

Procedure

Fill the glass one-half full of vinegar. Put two drops of food coloring in the vinegar and a squirt of dishwashing liquid. Stir with the craft stick. Put a tablespoon of baking soda in the vinegar mixture. Watch out!

Conclusion

The baking soda reacts with the vinegar to produce carbon dioxide gas. Baking soda is a base and vinegar is an acid. This is a chemical reaction because a new substance (carbon dioxide) is produced. The fizzing and bubbling are a result of the gas being released.
