Baking Soda Science Projects

If you have baking soda, you have the prime ingredient for a slew of science experiments! Here's a look at some of the projects you can try, including the classic baking soda volcano and growing baking soda crystals.

Baking Soda And Vinegar Volcano

If you only try one baking soda science project, make a baking soda and vinegar volcano. You can color the liquid to make the volcano erupt 'lava' or go with the original white eruption. The baking soda reacts with vinegar, a weak acid, to form water and carbon dioxide gas. If you add a small amount of detergent to the volcano, the gas gets trapped to make a thick foam.

Baking Soda Stalagmites And Stalactites

Baking soda is a good material for growing homemade stalagmites and stalactites. The non-toxic crystals form quickly and show up well against a dark-colored yarn. It's easiest to use gravity to get crystals to grow downward (stalactites), but constant dripping from the center of the yard will produce upward growing crystals (stalagmites), too.

Dancing Gummy Worms

Use baking soda and vinegar to make gummy worms dance in a glass. This is a fun project that demonstrates how vinegar and baking soda produce carbon dioxide gas bubbles.

Baking Soda Invisible Ink

Baking soda is one of many common household ingredients you can use to make invisible ink. All you need is baking soda and a bit of water to write a secret message. Baking soda weakens the cellulose fibers in paper. The damage is invisible under ordinary conditions but can be revealed by apply heat.

Ketchup And Baking Soda Volcano

There's more than one way to make a baking soda chemical volcano. The advantage of reacting ketchup with baking soda is that you get a thick, red eruption without having to add any dye or colorant.

Homemade Fire Extinguisher

The carbon dioxide you can make from baking soda can be used as a homemade fire extinguisher. While you won't have enough CO2 to put out a serious blaze, you can fill a glass with the gas to extinguish candles and other small flames

Make Baking Powder

Baking powder and baking soda are two different products used to make baked goods rise. You can use baking powder in place of baking soda in a recipe, although the result may taste a bit different. However, you have to add another ingredient to baking soda in order to make baking powder.
