Yuk!

Hello fellow blogger,

This term our theme  is Up Up and away and it is all about science. In the first week back at school we did something with baking soda and vinegar.  First we had to taste the vinegar and baking soda then we had to mix them together. It started to bubble an fizz and we had to taste the foam to see if it  tasted the same. Here is what we did after that.

	QUESTION.	If we mix this two different cim
	THESIS.	Vinegar taste sour and it is a liquid. Baking soda is a solid, soft white powder and it taste salty and horrible. They are both food substances but based on their different taste, they must be chemically
	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 size of the materials.

M I D D L E	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 2 cm. Step 2: Use a teaspoon to measure in one 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  in the container rose even higher .  When the mixture was tasted, the taste was unpleasant and was similar taste to the baking soda.

E N D	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 mean a gas must have been Produced. A quick check online showed us that the gas was carbon dioxide.
