Hi, Thank you for visiting JustAsk to get your education or parenting question answered. Unfortunately, though, it's not really clear what you are asking.

You tagged your question as "Helping my child with science," so are you asking about a particular science project, and whether or not it is a good one for your child to do? If so, I would suggest that you talk to your child's teacher about any specific guidelines he/she has for the science project assignment, and then review the soup in metal pan project against those guidelines. Here are additional tips for helping your child with science projects: http://www.education.com/topic/help-child-with-science-fair-projects/

If you accidentally categorized the question incorrectly and instead are asking a food/cooking safety question, here is a resource center on Education.com that you may find helpful: http://www.education.com/topic/child-food-safety/  I also found an article online about safe cooking pots: http://www.naturallifemagazine.com/0112/pots.htm However, please talk to your child's pediatrician about any specific health concerns you may have.

Thank you for asking!
