Foaming and Fizzing

Hi fellow bloggers
This term our school has a theme is Up, up and away and we are learning about science. We did an experiment on foaming and fizzing. What we did was, we tasted two food chemicals and they were vinegar and baking soda the vinegar tasted sour and the baking soda tasted plain. We mixed them together and observed what would happen as soon as we mixed them together it started to rise and bubble when the bubbling stopped we tasted it it was sour and plain at the same time. Before we started the experiment we wrote a science report on foaming and fizzing, I hope you liked my blog post :)

TITLE
Yuk and Yum!
QUESTION.

If we mix vinegar and baking soda together will we observe some kind of reaction?
THESIS.
Vinegar tastes sour and it is a liquid. Baking soda is a solid, soft white powder and it tastes salty and horrible. They are both food substances but based on their different taste, they must be chemically different. So, if they are mixed together, there might be a chemical reaction.
HYPOTHESIS.
We predict that when we mix vinegar with baking soda an observable reaction will accur. We might see and hear an explosion, fire, foaming, bubbles, fizzy or something else. The resulting mixture might look or taste different. There might even be a different in size of the materials.

EQUIPMENT
AND MATERIALS:
Baking soda
Vinegar
Container for mixing
Teaspoon for mixing
PROCEDURE
Step 1: pour the vinegar into a container to a depth of about 2cm.
Step 2: Use a teaspoon to measure in half teaspoon of baking soda.
Step 3: mix with a teaspoon.
Step 4: observe and record what happens.
OBSERVATIONS:
At step 2 the mixture started to fizz. A fizzing sound was heard, bubbles were seen to appear in the mixture and the materials rose higher in the container. At step 3, when the materials were mixed, even more bubbles appeared and the volume of the materials in the container rose even higher. When the mixture was tasted, the taste was unpleasant and was similar to the baking soda.

ANALYSIS
AND
CONCLUSION
The goal of this experiment was to see if an observable reaction would take place when vinegar and baking soda were mixed together. The result of our experiment prove that our hypothesis was correct. We predicted that there would be an observable reaction, and there was. There was lots of foaming and fizzing happening and bubbles appeared which means a gas must have been produced. A quick check online showed us that the gas was carbon dioxide.
