This experiment demonstrates how states of matter can change – mixing a solid with a liquid to create gas! The science behind this balloon baking soda experiment is the chemical reaction between the base – baking soda – and the acid – vinegar. When the two ingredients mix together the balloon baking soda experiment gets its lift! The gas produced from the two ingredients is carbon dioxide or CO2.

Vocabulary:

• Inflate

• Fizz

• Gas

• Expand

• Observe

• Extra Credit Word: Exothermic (absorbs heat, so it feels cold)

Materials:

• Empty 12-16 oz soda bottle (or any bottle about that size with a small neck)

• Balloon

• Baking Soda

• Vinegar

• Small funnel

• Teaspoon

• Small measuring cup

Directions:

1. Have your children scoop the baking soda into the balloon using the funnel

2. Help your children put the vinegar into the flask using a pipette or small measuring cup

3. Next, attach the balloon to the top of the flask; make sure not to pour the baking soda into the

   vinegar!

4. Ask your children what might happen, and why.

5. Count to 3 and everyone holds up their balloon so the baking soda falls into the vinegar,

   creating a chemical reaction and blowing up their balloon.

6. Let the kids know what will happen scientifically – SCIENCE:

   a. When baking soda and vinegar are mixed together, it creates a gas called carbon dioxide. The gas begins to expand in the bottle and starts to inflate the balloon.  The more gas that is created, the larger the balloon will inflate.
