Science is best understood through experiments and hands-on learning methods. In order to make science both entertaining and informative, Presidians of Grade 7 made lemon volcanoes that helped them understand the reactions between acids and bases. Lemon juice contains citric acid which when mixed with sodium carbonate (base) reacts to form carbon dioxide and sodium citrate, which causes the liquid to fizz and bubble. The students thoroughly enjoyed the activity.
