Product Description
In this lab students will use alka seltzer to understand the law of conservation of mass. I use this lab before I teach the law so students can discover it on their own. Materials needed: triple beam balances or electronic scale, graduated cylinder, ziploc bags, plastic cup, water, and alka seltzer tablets. I've also found that denture cleaner tablets work well and show a color change which the kids like.
