Exploring the World of Atoms
Year 4 Science Discovering the Building Blocks of Everything
What Do You Think Everything is Made Of?
Look around the classroom What do you see? What are these things made of?

Meet the Atom - Nature's Building Block
Atoms are incredibly tiny Everything is made of atoms Like invisible LEGO blocks Too small to see with our eyes

How Small Are Atoms?

Inside an Atom - The Nucleus
The center is called the nucleus Contains protons and neutrons Very dense and heavy Like the pit inside a peach

The Electrons - Tiny Dancers
Electrons zoom around the nucleus Much smaller than protons and neutrons They move incredibly fast Like planets orbiting the sun

Build Your Own Atom Model
Use clay or playdough Make a nucleus in the center Add electrons around the outside Create your favorite element

Different Atoms Make Different Elements
{"left":"Hydrogen - 1 proton\nHelium - 2 protons\nCarbon - 6 protons","right":"Oxygen - 8 protons\nIron - 26 protons\nGold - 79 protons"}

Atom Detective Challenge
Can you find atoms in your lunch? What elements might be in an apple? How about in water? Everything contains atoms!

Amazing Atom Facts
"If an atom was the size of a football stadium, the nucleus would be the size of a marble in the center!"
