This week, we did an science experiment called 'Foaming and Fizzing'. What we had to do was taste vinegar and baking soda individually and see if they have different taste, then we had to write a report with a title, question, thesis and much more. When we finished the report half way we got to mix the vinegar and baking soda together and taste it.
Here is the report.

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 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 chemical reaction will occur. We might see and hear an explosion, fire, foaming, bubble, fizzing or something else. The resulting mixture might look and taste different. There might even be a different in the size of the materials.

EQUIPMENT
AND MATERIALS:
|
Baking soda
Vinegar
Container for mixing
Teaspoon for mixing
|
PROCEDURE
|
Step 1: Pour some vinegar into a container to a depth of about 2cm.
Step 2:Use a teaspoon to measure in half a teaspoon of baking soda.
Step 3:Mix with 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 baking soda.

ANALYSIS
AND CONCLUSION |
The goal of experiment was to see if an observable reaction would take place when vinegar and baking soda were mixed together. The result of our experiment proves 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 mean a gas must have been produced. A quick check online showed us that the gas was carbon dioxide.
