Top 5 Scientific Discoveries That Changed Class 10 Science Forever

Science evolves constantly, and many classroom concepts are built on ground-breaking discoveries. Let's explore five revolutionary findings that have shaped the Class 10 Science curriculum and continue to empower students:

1. The Law of Reflection and Refraction
   Sir Isaac Newton and Willebrord Snell
   Every time we see ourselves in a mirror or watch a pencil bend in a glass of water, we're witnessing laws set by great scientists centuries ago. Their work forms the basis of your chapter "Reflection and Refraction."
2. The Cellular Theory
   Schleiden & Schwann
   The discovery that all living things are made up of cells changed biology forever. Today, topics like "Life Processes" start with this fundamental idea.
3. Chemical Equations and Balancing
   Antoine Lavoisier
   His contributions to the Law of Conservation of Mass help students understand why balancing equations in "Chemical Reactions and Equations" is so essential.
4. Magnetic Effects of Electric Current
   Hans Christian Ørsted
   The simple experiment where electric current caused a compass needle to move, led to a new era in electromagnetism—the basis of electric motor and generator concepts.
5. The Modern Periodic Table
   Dmitri Mendeleev
   His organization of elements makes "Metals and Non-metals" and "Acids, Bases, and Salts" chapters easier to understand by showing patterns in chemical behavior.

By exploring the stories behind these discoveries, students not only prepare for exams—they also feel the wonder of scientific progress!
