And on Future Minds, David Hewlett speaks with Christina Hanna about her project on redox reactions for economic stability. This project modelled an economic crisis that is looming due to the chemical reactions that are eroding huge pieces of infrastructure across the country.

Coral Chemistry activity

Chemistry matters! Build your own coral structure out of eggshells and explore the impact that acid can have on undersea creatures!

Download the activity as a [PDF]

WHAT DO YOU NEED?

  • 2 eggshells (from eggs that have been used)
  • 250 ml (1 cup) water
  • 250 ml (1 cup) white vinegar
  • 2 transparent cups or small containers
  • Hot glue gun and glue sticks

WHAT DO YOU DO?

  1. Build two small coral-like structures out of used eggshells. Use hot glue to stick the pieces together. 
  2. Glue one structure to the bottom inside each cup. 
  3. Fill one cup with water and the other cup with vinegar. 
  4. Make observations at the start and over time (e.g., 24 hours). Use the chart below to record observations. If you have a camera, you can take pictures of the eggshells as a record of your observations.

WHAT’S THE POINT?

Corals are tiny animals that build the structure they live on - the coral reef! The structures are made of layers of calcium carbonate, the same material eggshells are made of. 

You probably saw a lot of bubbles in the cup with the vinegar. What made these bubbles? The bubbles are the product of a chemical reaction between the vinegar and the calcium carbonate in the eggshells. This is because vinegar is an acid. Over time the vinegar breaks down the shells.

This same chemical reaction is happening in our oceans. Greenhouse gases make the oceans more acidic. This is called ocean acidification. Since acids break down coral and seashells, these animals could lose the structures that keep them safe.

WHAT ELSE?

Go Further!

  • Think like a climate scientist! What if the oceans get warmer? How does the temperature of water affect the coral-like structure? Try the same experiment using warm water and vinegar. Do you have a small shell from your last trip to the beach, try it out!
