law of conservation of mass

This is an experiment that explains the law of conservation of mass and how matter is neither created nor destroyed. To begin you need to get all your materials. You will need a plastic bottle, a digital scale, Alka-Seltzer, a testing tube, an acidic solution and a small beaker. First, measure the things individually. Measure the lid, the Alka-Seltzer, the testing tube and the small beaker. Then, measure 10 mL of the acidic solution in a small beaker and then transfer it to the testing tube. Then, drop the testing tube into the water bottle at a 45 degree angle. Measure the water bottle carefully and add the Alka-Seltzer. Shake the bottle until the acidic solution comes in contact with the Alka-Seltzer.



Be sure to write everything down. When I made this experiment, I found that my bottle with the lid weighed 26.29 grams, the Alka-Seltzer weighed 3.43 g, the testing tube weight 8.60 g, the small beaker 27.20 g, the beaker with the solution 37.35 g, the bottle with the testing tube 42.79, the bottle with the testing tube and the Alka- Seltzer 46.011 g. At the end of the experiment, the bottle containing everything weighed 45.82 g and the difference between this and when it weighed 46.011 is that the carbon dioxide left. Be sure to try this experiment but always remember to be safe and ask for parental help if necessary.
