🧪 Science with Sarah: Dancin’ spaghetti 🍝

A great study in chemical reactions AND density

👉 Watch the video of Sarah’s science experiment at Indian Creek Elementary here!

Hello parents, teachers and students! Today’s experiment explores the chemical reaction between baking soda and vinegar. We’re gonna make spaghetti dance!

Be sure to check out GMSA@9 on Wednesdays when Meteorologist Sarah Spivey does the demonstrations and explains the science behind it.
