@learningwithdad: 🧪 30 Days of STEM – Day 12! 🥚 Two days ago we put an egg into vinegar and left it to see what would happen… and today it was finally time for the reveal! 👀 The vinegar reacted with the calcium carbonate in the eggshell, dissolving the hard shell and leaving the soft membrane behind. 🤯 The kids loved checking on it and seeing how much it had changed over the two days! Such a simple experiment, but a brilliant way to learn about chemical reactions and how materials can change. 🔬 Would you try this one at home? 👇 #30DaysOfSTEM #STEMForKids #EggInVinegar #ScienceForKids #kidsscience
