Egg Experiment Observations and Procedures

In this video tutorial, the teacher guides children through an experiment involving eggs, vinegar, and water. The experiment demonstrates how vinegar dissolves eggshells over 48 hours, while water does not. The video includes setting up the experiment, observing initial reactions, and discussing the results after 48 hours. The children are encouraged to engage with the experiment by observing changes and playing with the eggs. Safety precautions, such as wearing gloves, are emphasized throughout the process.
