Goal 14 "Life below water"

Our physics and chemistry teacher gave us the idea of making a very large poster in which the students of the center will be asked: "How many years do you think it would take for these objects to degrade in the oceans?"

Besides of that large poster that the teacher told us, we put some small cards with the name of the objects and the real object so students could see them.
After three weeks of work we lowered it to the entrance of the institute and we let them put their opinions of how much they believed that they would take time to degrade.

After a week we saw that many people had already answered and we decided to put the right answers and that is how we finished our project.
