It was STEM day in 2nd grade! First, our young scientists discovered chemical reactions by mixing baking soda with vinegar in empty bottles. The reactions heard in the STEM Lab as the colorful balloons filled with carbon dioxide was sheer glee! We were so excited that we had to share our discoveries with Mrs. Shumny. Next, we learned how to make the perfect paper airplane & how they fly. We tested the airplanes outside and learned that trick to a high flying paper airplane is to fold them with sharp creases. A fun and interesting day was had by all!
