Teaching the conservation of mass through experiments can be tricky.

Challenges:

• Getting exact measurements is really important. If there's a mistake, it can cause confusion.
• Sometimes, experiments don't show the main ideas clearly if conditions aren't controlled.
• Some students might find it hard to balance complicated equations.

Ways to Help:

• Try using simple reactions, like mixing baking soda and vinegar. You can see how mass changes if you measure carefully.
• Give students guided worksheets to help them practice balancing equations. This will make learning easier and more effective.
