Sharing is caring - thank you for spreading the word! When combined, these two ingredients create a chemical reaction that fizzes and bubbles, much to the delight of my children. Having done all of these activities, my kids are now well aware of what happens when baking soda and vinegar combine. Then I challenged my kids to determine which two powders were baking soda and which two liquids were vinegar.

The great baking soda and vinegar experiment

Will the weight go up, down, or stay the same? Now that you have your guess, flip up the balloon to empty all of the baking soda into the flask see photo below.

Stand back, watch the balloon grow, and watch the scale see photo below. This result is especially confounding if you happen to be familiar with the law of conservation of mass : In any closed system, mass is neither created nor destroyed by chemical reactions or physical transformations. In short, the mass of the products of a chemical reaction must equal the mass of the reactants.

Did you really just violate the law of conservation of mass? The answer is below…but to avoid a spoiler, skip down to the Going Further section before reading on.

When you added the baking soda to the vinegar, the two combined to make carbon-dioxide gas, which inflated the balloon. The expansion of the balloon changed the weight of your sealed flask because you and your entire experiment are submerged in a fluid: air. Just like water, air is a fluid, and fluids buoy up objects. By increasing the volume of your sealed flask, you cause it to displace more air, increasing the buoyant force on it and reducing its weight.

The mass stayed the same due to the law of conservation of mass, but because of buoyancy, the weight went down! Consider possible explanations for the weight change: Did the balloon leak? Did something funny happen to the scale?

What else might be going on? Plan an experiment to test your theory, gather equipment, and carry it out. Does the weight loss of your flask match the theoretical prediction?

This activity is meant to spark more experimentation. Having a variety of supplies on hand will allow for creative investigation into this phenomenon.

Video Demonstration. Put on your safety goggles. Attach a balloon to the end of the funnel. Using the funnel, pour two level teaspoons 10 mL of baking soda into the balloon see photo below. Attach the balloon to the flask, making sure the neck of the balloon is snugly seated below the lip or collar of the flask. As you work, keep the balloon hanging off to the side of the flask so none of the baking soda falls into the vinegar—yet. To begin, carefully put the sealed flask onto the scale and write down its starting weight.

Write down the final weight when the reaction is over. Surprise—your balloon swelled enormously, but the weight actually dropped. Related Snacks Feeling Pressured Feel atmospheric pressure changes by stepping into a garbage bag.

Last updated September 11, In this demonstration, the teacher will perform a reaction between acetic acid vinegar and sodium bicarbonate baking soda in order to inflate a balloon and to introduce the concept of a chemical reaction to students. Students will observe the reaction, and identify indicators of chemical change as well as discuss the different types of matter that are involved. This demonstration will help prepare your students to meet the performance expectations in the following standards:. You will have the opportunity to observe a demonstration of a chemical reaction carried out by your teacher. Record your observations for what happened during each portion of the experiment in the data table below. Summary In this demonstration, the teacher will perform a reaction between acetic acid vinegar and sodium bicarbonate baking soda in order to inflate a balloon and to introduce the concept of a chemical reaction to students.

Vinegar Baking Soda ~ Paint Experiment

Science Kindergartners Experiment 30 Comments. Vinegar is acetic acid dissolved in water and baking soda is a base called sodium bicarbonate. Initially, the reaction makes carbonic acid which is unstable.

Balloon Blow-Up Science Experiment

Adding baking soda to vinegar is a well-known, frequently used reaction that illustrates gas formation. Both ingredients are readily available from the grocery store, and both can be safely discarded down the sink.

Baking Soda and Vinegar Balloon

Have you seen our Exploding Rocket Art? It is seriously cool! This is a milder version, but still lots of fun for preschool kiddos. Mix baking soda into the egg dye until you form a thick paste. Pour vinegar into the squeeze bottle. The paint tends to settle, so you may need to give is a quick stir every now and then. For our first experiment the kids used an angled spatula normally used for icing cakes to spread the thick paint onto a cardboard.
