Begin the lesson by inflating a balloon to demonstrate volume. Explain that the balloon, the air inside, and even you are matter, highlighting that matter is anything with mass and volume.

What Is Matter?
Learning Objectives
- Understand that matter is anything that has mass and volume.
- Differentiate between mass and volume, and identify units used to measure each.
- Explain the concept of density and how it relates to mass and volume using examples like a foam ball and a baseball.
- Recognize that matter is composed of atoms, which are the basic units of all matter.
- Identify the three states of matter and understand that the state is determined by the arrangement of its atoms.
Introduction and Hook
Direct Instruction
Discuss the concepts of mass and volume, using examples like a foam ball and a baseball to illustrate differences in density and mass.
Introduce the three states of matter—solids, liquids, and gases—and explain how the arrangement of atoms determines the state.
Guided Exploration
Watch the video 'What is Matter?' to reinforce the concept that matter is anything with mass and volume. The video includes demonstrations like inflating a balloon and using a balance to compare mass.
Explore particle motion in different states of matter with the video 'Particle Motion in Matter'. This video helps students understand how particle arrangement and movement define physical properties.
Hands-On Activity
Conduct a hands-on activity where students compare the masses of objects of similar volumes using a balance. This reinforces the understanding of mass and volume as properties of matter.
Independent Practice
Assign students the task of identifying and classifying objects around the classroom or home as solids, liquids, or gases, based on their properties.
Check for Understanding
Use the 'States of Matter – Comprehension' assessment to evaluate students' understanding of mass, volume, and particle arrangement in different states of matter.
Review and Reflection
Facilitate a class discussion to reflect on the properties of matter and how they relate to everyday objects. Encourage students to share examples and insights.
Assessment and Extension
Administer the 'Review – Matter and Materials' assessment to gauge students' understanding of the unit's key concepts, including transparency, conductivity, and phase changes.
Try the Quiz
For further exploration, students can engage in the 'Design, Build and Improve a Boat' activity, which challenges them to apply their understanding of material properties and buoyancy.
