🧪 SCIENCE LESSON: WHAT IS MATTER MADE OF?

Grade: 4th
Subject: Science
Duration: 1–2 hours

🎯 LEARNING OBJECTIVES

Students will be able to:

• Understand that all matter is made of tiny particles called atoms.
• Identify atoms as the basic building blocks of matter.
• Recognize that atoms join to form molecules.
• Describe simple parts of an atom (protons, neutrons, electrons).

📘 LESSON CONTENT 

🔍 What is Matter?

Matter is everything that has mass and takes up space.

Examples:

• Water 💧
• Air 💨
• Books 📚
• Animals 🐾

🧪 What is Matter Made Of?

Matter is made of tiny particles called atoms.

Atoms are so small that we cannot see them, even with our eyes.

👉 Everything around us is made of atoms.

🔗 Atoms and Molecules

Atoms can join together to form molecules.

👉 Example:

• Water (H₂O) is made of molecules
• Each molecule is made of atoms

⚛️ PARTS OF AN ATOM (SIMPLE)

Atoms have three main parts:

• Protons ➕ (positive)
• Neutrons ⚪ (no charge)
• Electrons ➖ (negative)

👉 You don’t need to memorize charges deeply—just recognize the parts.

🧠 KEY IDEA

👉 Atoms are the building blocks of all matter.

✏️ EXTENDED NOTEBOOK KEY CONCEPT

All matter is made of very small particles called atoms. These particles are the basic building blocks of everything in the universe.

Atoms are too small to be seen, but they exist in all objects and living things. Atoms can combine with other atoms to form molecules. For example, water is made of molecules, and each molecule is made of atoms.

Each atom has three main parts: protons, neutrons, and electrons. These parts work together to form the structure of the atom.

Understanding atoms helps us understand how matter is formed and how it behaves.

👉 Key idea: Everything around us is made of atoms.

🎨 CLASS ACTIVITY

🖍️ Main Activity

Draw and label matter.

Instructions:

• Draw 3 objects (example: water, air, a book)
