Let’s start out the new year with some new-looking pennies! 💰 Do you have any old dirty ones laying around? Do you know how they get so dirty? The oxygen in the air binds with the copper in pennies, creating copper oxide. This new molecule is what creates the brown or black color that emerges. Grab those dirty pennies and let’s experiment! Tune in on Mondays for #makeitmonday where we will feature a STEAM activity to help you discover the science in everyday things! 🧪 #gno2023 #tempegeeksnightout #gno #tempeaz #stem #steam
