Objective

By the end of this lesson, you will be able to create your own magic potions using simple chemistry principles.

Materials and Prep

• Water
• Food coloring
• Baking soda
• Vinegar
• Measuring spoons
• Cups or containers
• Stirring utensils
• Protective eyewear (optional)

Make sure you have adult supervision and permission to use these materials.

Activities

1. Create a fizzing potion:

   • Fill a cup with water.
   • Add a few drops of food coloring to the water.
   • Add a tablespoon of baking soda to the cup.
   • Slowly pour vinegar into the cup and observe the reaction.

2. Create a color-changing potion:

   • Fill two cups with water.
   • Add different colors of food coloring to each cup.
   • Add a tablespoon of baking soda to one cup and stir.
   • Add a tablespoon of vinegar to the other cup and stir.
   • Observe and compare the color changes in the two cups.

Fourth Grade Talking Points

• "Chemistry is the branch of science that deals with the properties, composition, and behavior of matter."
• "In our activities today, we are using different substances like baking soda and vinegar, and observing how they react with each other."
• "When baking soda and vinegar mix, they undergo a chemical reaction that produces carbon dioxide gas. This gas creates the fizzing effect."
• "Food coloring is made up of different molecules that absorb and reflect light, which is why we see different colors."
• "When we mix baking soda with water, it changes the pH level and can cause the color of the food coloring to change."
• "Vinegar is an acid, and when we mix it with the baking soda, it neutralizes the baking soda's basic properties, resulting in a color change."
