Yesterday we went to Room 20. We did an experiment called expanding bags. We needed vinegar, baking soda, a plastic bag and a tissue. I thought it would go all bubbly and would puff up and pop!! We put the baking soda in a tissue. Then we dropped it in the vinegar. It made a gas called carbon dioxide. The bag puffed up and went pop!! It popped because the vinegar made a gas called carbon dioxide. by Kaleb Demanser
Yesterday we went to Room 20. We did Science. It was exploding. We used bags, baking soda, white vinegar and a tissue. We put the ingredients in the bag and we shook it. We went outside and we had a good shake. It got fatter and fatter and POP! I made the gas carbon dioxide.
