@learningobserved: Science in action! 🧪✨ Here are the exact measurements to try both off gassing experiments at home with your kids: Reaction 1: Classic CO^2 Fizz 100ml warm water 1 tbsp baking soda 1 tbsp washing-up liquid Food colouring 50ml vinegar (add this last to trigger the fizz!) Reaction 2: Elephant Toothpaste (Oxygen Release) 100ml hydrogen peroxide (3% or 6% household solution works great) 1 tbsp washing up liquid Food colouring The Activator: 1 sachet (7g) dried yeast dissolved in 3 tbsp warm water How to test the gas: Once your elephant toothpaste foam erupts, light a wooden splint, blow out the flame so it's just glowing, and gently dip it near the oxygen rich bubbles (watch it reignite)! 🔥 Have your kids note down the differences in foam speed, texture, and gas properties between the two. 📍 Save this post for your next hands on STEM session! #stemlearning #scienceathome #homeeducationuk #learningthroughplay #homeschool
