Core Skills Analysis

Science

  • The 11-year-old student learned about chemical reactions by observing the fizzing effect produced by the lemon and baking soda interaction in the volcano.
  • They gained an understanding of acids and bases through the reaction between the citric acid in the lemon and the sodium bicarbonate in the baking soda.
  • The student explored the concept of carbon dioxide production as they observed the bubbles forming and escaping from the mixture during the volcanic eruption.
  • They also learned about pressure as they witnessed the build-up of gases within the lemon volcano before it erupted.

Tips

To further explore the concept of chemical reactions, encourage the student to try different variations of the lemon volcano experiment, such as changing the proportions of lemon juice and baking soda or adding other ingredients to observe how it affects the reaction. Additionally, they can research and explore other natural acids and bases that can be used in similar experiments.
