Sea Shells in Acid Lab Experiment

This is a lab activity where students learn about the effects of acidic water on shelled animals. The students set up three beakers- one for water, one for salt water, and one for vinegar (acid). They place a seashell in each and make observations over the course of three days. The sea shells and vinegar create a bubbly reaction that piques the students' curiosity. My students love it! Great for science topics covering life sciences, ocean chemistry, global warming, mollusks and the animal kingdom, pH, the scientific method and lab reports.

Materials Needed:
Sea shells (I get mine from the Dollar Tree!)
Vinegar
Salt
Water
Cups

This activity aligns with NGSS-MS-ESS3 (Human Impact on Earth). Consider the impact that climate change can have on marine organisms.
