En clase hicimos un experimento poniendo clavos o tornillos de hierro, acero y acero inoxidable en agua con y sin oxigeno y en un bote cerrado para ver y comprobar qué efectos producían en cada uno de ellos.
In Science lessons we are learning the changes that occur in some materials. One of these changes is rusting (oxidation). We went to check how the protection of the metals avoid them to rust.
In class we did an experiment putting nails or screws of iron, steel and stainless steel in water with and without oxygen and in a closed pot to see and check what effects they produced in each one of them.
Starting the experiment.
Checking on real materials in the street:
- Outside the school.
- Outside the firestation.
