Can You Make a Carbon Sink With What's Under Your Sink?

(7th grade) Sarrah - 1st place in 2 regional competitions, top 300 in country

Interested with the idea of carbon sequestration, I explored ways I could create my own carbon sink at home. After lots of research, I learned that acid-base neutralization may work to sequester CO2. Aerating different solutions of sodium hydroxide in a test tube, I found that sodium hydroxide could sequester carbon dioxide on a small scale.

I placed first at the regional NCSEF and NCSAS competitions and was promoted to states, however due to COVID, the state competitions were cancelled. Everyone who was eligible for the state competition was invited to participate in the online national science fair competition Broadcom MASTERS (Math, Applied Science, Technology, and Engineering for Rising Stars), an opportunity usually only offered to the top 10% of Junior and Senior division projects at the state competition. My project and 299 others were chosen from over 3,000 other entrants as the top 300 MASTERS projects, my project being one of 5 selected from North Carolina.
