Chemical Reactions

Our Science Experiment

Baking soda
Food Colouring

Some of our predictions were 
The cup will explode because it has an acid and an alkaline.
It will bubble everywhere.
The colour will change when the bubbles bubble. 

Baking soda tastes yuck! Well to most people.
First we put 1/4 of a cup of baking soda in a cup.

Adding a few drops of food colouring

Slowly we poured in the vinegar.
Something is happening!
A chemical reaction!
Waves crashing over the cup
Lava bubbling out of the cup
The vinegar mixed with the baking soda and made bubbles. The bubbles are carbon dioxide. It is a gas like in fizzy drinks.

Boom! The science experiment exploded out of the cup on to the table. It was a dark dark red. The bubbles bubbled up the cup. Pop pop pop pop went the devil bubbles. The explosion speedily happened. If you want to do this experiment you will need two scoops of baking soda one cup of vinegar and four little drops of food colouring. Next you have to put the colouring and the vinegar into the cup to make it go Boom!

Bubble bubble bubble the magic ingredients over flowed like a fizzy drink. It was covering the container with vinegar and baking soda. It was a chemical reaction. When the soda was ready the chemical reaction gushed down the cup. The bubbles were pouring down the cup. Then the bubbles got on the plastic lid. There were bubbles all over the plastic lid and the table.

Boom! The experiment exploded with bubbles coming up and up. Soon we had to watch the experiment. Soon it rose up and red bubbles appeared up fast like the wind. the experiment looked like a volcano exploding down an angry mountain. First we put in baking soda. Next we put in any colour of food colouring. Then we put in vinegar. Suddenly the experiment exploded everywhere.

Pop pop the science experiment started to crackle and fizz over the rim of the cup. Blue crashing waves smashed into the hard sand. The bubbles rose quickly up so you have to watch carefully because I nearly missed the reaction. If you want to do this experiment you've got to use food colouring, vinegar and baking soda. First you put a third of a cup in your container. Second you drip in food colouring in your container. Last of all you deposit the vinegar in the container and something impressive will happen.

  1. WOW! Room5 what great sentence starters you are using. I can tell by the way you all have used amazing words in your story, that it was a very exciting experiment. Beau I love the the piece where you wrote Blue crashing waves smashed into the hard sand. Keep up the AWESOME work.

  2. I really like the bit when it when it came up like a valcano
