Have you ever heard of Marie Curie? She was a brilliant scientist who, along with her husband Pierre, made some amazing discoveries in their science lab. They spent a lot of time studying a special material called pitchblende. While they were investigating it, they discovered two brand-new elements!
The first element they found was called polonium. Marie named it after her home country, Poland. The second element they discovered was radium. They chose this name because radium gave off very strong rays of energy. These discoveries were so important that both elements were added to the periodic table, which is like a big chart that shows all the known elements in the world.
Marie and Pierre Curie didn’t just stop at discovering new elements. They also came up with a new word: radioactivity. This term describes elements that emit strong rays of energy, just like radium does. Their work helped scientists understand more about how atoms work and how energy can be released from them.
Did you know that Marie Curie was the first woman to win a Nobel Prize? In fact, she won it twice! Her discoveries have helped scientists in many fields, including medicine, where radium is used to treat certain types of cancer.
Marie Curie’s work was groundbreaking and has inspired many scientists who came after her. Her discoveries about radioactivity changed the way we understand the world and continue to be important in science today.
Imagine you are a scientist like Marie Curie. Design your own element by giving it a name, symbol, and unique properties. Draw it on a piece of paper and explain why your element is special. Share your creation with the class!
Explore the periodic table to find polonium and radium. Write down their atomic numbers and any interesting facts you discover about these elements. Discuss with your classmates why these elements were significant in Marie Curie’s research.
Conduct a safe classroom experiment to learn about radioactivity. Use materials like glow-in-the-dark stickers to simulate how radioactive elements emit energy. Observe and record your findings, then discuss how this relates to Marie Curie’s discoveries.
Work in groups to create a short skit about Marie Curie’s Nobel Prize achievements. Assign roles such as Marie, Pierre, and the Nobel committee. Perform your skit for the class and discuss the impact of her work on science and society.
Create a timeline of Marie Curie’s life and her major discoveries. Include important dates, such as when she discovered polonium and radium, and when she won her Nobel Prizes. Present your timeline to the class and highlight how her work continues to influence science today.

I wonder about Marie Curie and her husband, Pierre. They spent many hours in the science lab investigating a material called pitch blend. While investigating it, they found two new elements. These two elements were added to the periodic table: polonium was one of the elements, and radium was the other. She named it radium because it gave off such strong rays. Marie and Pierre Curie also came up with the term “radioactivity” to describe other elements that emitted strong rays.

Science – The study of the natural world through observation and experiments. – Science helps us understand how things work, like why the sky is blue.
Chemistry – The branch of science that studies substances and how they interact, combine, and change. – In chemistry class, we learned how different chemicals react with each other.
Elements – Basic substances that cannot be broken down into simpler substances by chemical means. – Oxygen and hydrogen are elements that combine to form water.
Radioactivity – The process by which certain elements emit energy in the form of particles or waves. – Marie Curie studied radioactivity and discovered new elements.
Energy – The ability to do work or cause change, such as moving an object or heating something up. – The sun provides energy that plants use to grow.
Atoms – The smallest units of matter that retain the properties of an element. – Everything around us is made up of tiny particles called atoms.
Periodic – Occurring at regular intervals; in chemistry, it refers to the periodic table, which organizes elements by their properties. – The periodic table helps scientists understand how elements relate to each other.
Radium – A radioactive element discovered by Marie Curie, used in some medical treatments. – Radium was once used to treat certain types of cancer.
Polonium – A rare and highly radioactive element discovered by Marie Curie. – Polonium is used in some scientific research due to its radioactivity.
Discoveries – New findings or knowledge gained through exploration or research. – The discoveries of new elements have expanded our understanding of chemistry.
