The Candle Under a Glass science experiment is a simple yet fascinating STEM activity that helps children explore the role of oxygen in combustion. By placing a lit candle in a shallow dish of coloured water and covering it with a glass, students can observe the flame gradually go out as the oxygen inside the glass is used up. They will also notice the water level rising inside the glass, providing an excellent opportunity to discuss air pressure, oxygen consumption, and the science behind burning.
Perfect for classrooms, homeschool lessons, science fairs, and supervised home learning, the Candle Under a Glass experiment encourages children to make predictions, observe changes, and record their findings like real scientists. It introduces important scientific concepts such as combustion, oxygen, air pressure, and scientific observation while developing critical-thinking and inquiry skills. Easy to perform with common household materials and adult supervision, this engaging STEM activity makes learning about science both exciting and memorable.
