Hello fellow bloggers

This term our theme is Up,up and away. That means we are learning about science. We did an experiment  where we had to taste baking soda and vinegar yuck! We mixed them together and recorded and what happened.

QUESTION.

If we mix vinegar and baking soda what would the reaction?
THESIS.
Vinegar tastes sour and it is a liquid. Baking soda is 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  chemical reaction will occur . we might see and hear an explosion ,fire,foaming,bubbles .fizzing or something else . the resulting mixture might look and taste different . there might even be a difference in size of materials

EQUIPMENT
AND MATERIALS:
Half teaspoon baking soda
Vinegar
Container for mixing
Teaspoon for mixing
PROCEDURE
Step 1: pour some vinegar into a container to depth of about 2cm
Step 2: use  a teaspoon to measure in half a 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 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 means a gas must have been produced. A quick check online showed us that the gas was carbon dioxide.
