ClassX Video Lessons Youtube Channel Next Generation Science Chemical Change – Bicarbonate Soda and Vinegar
Have you ever mixed baking soda and vinegar? It’s a fun way to see a chemical change in action! Let’s explore what happens when these two ingredients come together.
A chemical change is when substances combine and create something new. This is different from a physical change, like ice melting into water, where the substance stays the same. In a chemical change, the original substances change into different ones.
When you add bicarbonate soda (also known as baking soda) to vinegar, something exciting happens. You’ll see bubbles and foam forming quickly. This is because a gas called carbon dioxide is being created. The bubbling is a sign that a chemical change is taking place.
The bubbles form because vinegar, which is an acid, reacts with bicarbonate soda, a base. When they mix, they create carbon dioxide gas. This gas is what makes the bubbles and foam you see. It’s like a mini science experiment you can do at home!
Did you know that carbon dioxide can put out a fire? Fire needs oxygen to keep burning. When carbon dioxide is released, it pushes away the oxygen, making it hard for the fire to keep going. This is why carbon dioxide is used in some fire extinguishers.
You can try this experiment at home with the help of an adult. All you need is some baking soda, vinegar, and a container. Watch the bubbles form and think about the chemical change happening right before your eyes!
Learning about chemical changes can be a lot of fun. It’s amazing to see how different substances can create something new and exciting. Keep exploring and discovering the wonders of science!
Bubble Race Experiment: Gather some small containers, baking soda, vinegar, and food coloring. Add a few drops of different food colors to each container. Then, add a spoonful of baking soda to each one. Pour vinegar into each container at the same time and watch the colorful bubbles race! Discuss with your friends or family which color bubbled the fastest and why you think that happened.
Observation Journal: Create a journal to record your observations of chemical changes around you. Start with the baking soda and vinegar experiment. Draw what you see before, during, and after the reaction. Write down what you notice about the bubbles and foam. Over the next week, look for other examples of chemical changes, like rust forming on a nail or a banana turning brown, and add them to your journal.
Fire Extinguisher Role Play: Pretend you are a firefighter using carbon dioxide to put out a fire. Use a small candle (with adult supervision) and a cup of vinegar and baking soda. Light the candle and then carefully pour the vinegar into the cup with baking soda near the candle. Watch how the carbon dioxide gas puts out the flame. Discuss why carbon dioxide is important in this process and how it helps keep us safe.

Chemical change: evidence of chemical change. What happens when bicarbonate soda is added to vinegar? Carbon dioxide forms, creating foam and bubbles inside the beaker. Bubbling is evidence of a chemical change. Carbon dioxide extinguishes the flame by displacing the oxygen that the fire needs to burn.
