🧪 Antoine Lavoisier

Antoine Lavoisier was a brilliant scientist known for discovering how burning and breathing use oxygen.

🔬 What Did Antoine Lavoisier Do?

Antoine Lavoisier was born in Paris, France, in 1743. He loved doing careful experiments and, most importantly, weighing everything before and after. By doing this, he showed that when something burns or changes, the total amount of matter stays the same. He named the gases oxygen and hydrogen, and showed that water is made of both. His wife, Marie-Anne, worked with him, making drawings of their experiments and translating science books.

🌟 Why Antoine Lavoisier's Work Still Matters

Lavoisier helped turn chemistry from guesswork into a real science based on measuring things. He wrote one of the first lists of chemical elements and helped create a clear system for naming chemicals that scientists still use. Every time a scientist carefully measures the results of an experiment, they are following his example.

🏫 Classroom Activity

Light a candle safely (adult supervised) or watch a video of one, and talk about how it needs oxygen from the air to keep burning.

🏠 Homeschool Activity

Weigh an object on a kitchen scale, then rearrange or combine it with something else and weigh again, talking about how matter changes form but isn't lost.
