Experiments in class (4th Year Primary Education)
The students of 4th year Primary Education are carrying out different experiments in class.
In this case, the aim of the experiment was to demonstrate the effectiveness of toothpaste and the importance of maintaining proper oral hygiene.
It consisted of putting one egg covered with toothpaste in a container filled with vinegar and another egg without toothpaste in a container with vinegar, and then waiting 24-48 hours. The experiment showed that the protein in the egg (similar to dentine) falls apart if it is not protected, while the egg with toothpaste remains intact.
