Option 1 : Design a chamber which prevents rusting of iron nails.

A chemical change, also known as a chemical reaction, is a process in which one or more substances are altered into one or more new and different substances. In other words, a chemical change is a chemical reaction involving the rearrangement of atoms. Here new substances are formed and they can't be reversed. " Design a chamber which prevents rusting of iron nails" is an example of an 'authentic task' to assess students' understanding related to chemical changes as:

Here the students come to know why the rusting of iron happens and in which conditions it happens.
The substances they use to design the chamber shows their understanding of the chemical changes.
If the students design a chamber that is open and allows moisture in it then their lack of understanding can be assessed.
Designing that chamber requires a thorough understanding of the topic of chemical changes and how it takes place.

Hence "Design a chamber which prevents rusting of iron nails" is an example of an 'authentic task' to assess students' understanding related to chemical changes.

On the other hand, creating a filtration mechanism, observing the changes, and creating a cool chamber don't assess students' understanding related of chemical changes because these tasks don't require the complete knowledge of chemical changes.
