📢We did some FREEZING, STORMY winter science last week in our winter ESL unit🥶 Here’s a scientific explanation for what is happening in the last part of the video! 🥶What causes this chemical reaction and how is this snowstorm created? There’s lots of cool science stuff going on here! ✨ 1️⃣ For starters, the water is more dense than the oil, so it sinks through the oil and sits at the bottom. Also, the oil and water are immiscible (un-mixable), so they will always separate back into separate layers. 2️⃣ The acrylic paint is water based, so it will mix with the water to make white water. If you used oil based paint (for example, blue would be lovely!), the oil paint would mix with the baby oil and make the oil blue. 3️⃣ On a side note, food colouring is also water based, so if you add it to your jar, it will mix with the water and will make your bubbles blue. The Alka Seltzer has sodium bicarbonate (baking soda) and citric acid in it. When those mix with water they make bubbles of carbon dioxide which rise up to the surface through the oil. When the carbon dioxide is released into the air, the remaining water falls back down through the oil. (Why? Because water is more dense than the oil) 4️⃣ The carbon dioxide carries some of the water and paint mixture up with it. Since the oil and water are immiscible, these bubbles are easy to see in the oil. If we were doing this experiment without any oil, we’d basically have a fizzing jar and we wouldn’t be able to see those awesome little bubbles rising up and falling down again! ✨Isn’t science so beautiful and so CRAZY at the same time?! 🥶 💥If you think your child would like my classroom and if you feel like we are the right fit, feel free to reach out, group classes enrollment for 2024 opens in January! 💥 Eagerly expecting you, Alice ELLoquent #onlineenglishforchildren #onlineenglish #onlineenglishclassroom #esl #eslteacher #onlineenglishteacher #englishgames #stemforkids #scienceforkids
