Middle School Physical Science explores the fundamental concepts of matter, energy, and the interactions between them through engaging experiments and real-world applications.
Atoms are the tiny building blocks that make up all matter. Imagine them as super small Lego pieces that can stick together in different ways!
When two or more atoms join together, they form a molecule. Water, for instance, is made of two hydrogen atoms and one oxygen atom (\(H_2O\)).
Understanding atoms and molecules helps scientists create new medicines, develop cleaner fuels, and even design better materials for sports equipment.
A water molecule is made of two hydrogen atoms and one oxygen atom.
The oxygen you breathe is made up of two oxygen atoms bonded together.
Atoms are the building blocks of matter, and molecules are groups of atoms bonded together.
