Objective

By the end of this lesson, you will be able to understand and observe basic chemical reactions.

Materials and Prep

• Clear plastic cups
• Baking soda
• Vinegar
• Food coloring (optional)
• Measuring spoons
• Tablespoon
• Water
• Small bowl or container
• Tablecloth or newspaper (to protect the work area)
• An adult to supervise and assist with the experiment

Prior to the lesson, make sure you have all the materials ready and set up a safe and clean work area.

Activities

1. Mixing Baking Soda and Vinegar

   1. Place a clear plastic cup on the tablecloth or newspaper.
   2. Add 1 tablespoon of baking soda to the cup.
   3. If desired, add a few drops of food coloring to the baking soda.
   4. Slowly pour vinegar into the cup and observe the reaction.
   5. Observe and describe what happens when the baking soda and vinegar mix.

2. Baking Soda and Water

   1. Fill a small bowl or container with water.
   2. Add 1 tablespoon of baking soda to the water.
   3. Mix the baking soda and water together using a spoon.
   4. Observe and describe what happens when baking soda is mixed with water.

Kindergarten Grade Talking Points

• "Today, we are going to learn about chemical reactions."
• "A chemical reaction is when two or more things mix together and change."
• "We will be using baking soda and vinegar to see a chemical reaction."
• "When we mix baking soda and vinegar, it makes bubbles and fizzes. It's like a volcano erupting!"
• "We will also mix baking soda with water to see what happens."
• "Remember, always ask an adult for help and supervision when doing experiments."
