science project for 5th grade
 
Do you have any ideas for a science project to test plastic food wrap -- which one, if any, keeps food fresher longer?

Plastic Bags
 
I have an idea for you. Put the bread into the plastic bag, then soak the plastic bag. Wait a week, and see if any mold has growen inside the bag, which means water has gotten in. This means that it's probably not a good choice of a plastic bag to store parishables in.
