At this week for Sisters4Science, the Ariel girls go to do some chemistry and make lunch bag rockets! By using vinegar, baking soda, water, and tissue, the girls were able to create a reaction that turned into an explosion in a Ziplock bag! With the help of Christiana and Brianna, all of the girls were given vinegar and water to mix in a Ziplock bag. Once that was mixed, Bailey gave all of the girls a small amount of baking soda into a tissue. The girls then had to quickly drop the tissue into the bag and close it to watch it expand! The reaction took no more than 10 seconds, and soon enough all of the girls were running away from their exploding rockets! When I asked the girls what they thought was happening inside of the bags, Ja’Nyha told everyone that the baking soda and vinegar were reacting together and all of the carbonation from the reaction was making the bag expand. Looks like Ja’Nyha knows her chemistry! It was very impressive!
Because the experiment was so messy, the girls got to go outside to make their lunch bag rockets. After they were done, they got some more physical activity in and played a round of ‘Red Rover’ on the playground! All in all it was an exciting day of science and fun at Ariel
