This document discusses the properties of matter. It explains that the two main properties of matter are mass and volume. Mass is measured in kilograms using a balance, while volume is measured in litres using a graduated recipient. The document then lists and defines other properties like fragility, resistance, conductivity, elasticity and transparency. It concludes with review questions about these properties and activities to reinforce the key concepts covered.

1. Unit 5: matter
Natural science
4TH OF PRIMARY

2. 2 properties of matter: Mass and volume
 MASS
 The quantity of matter that an object has.
 It is measured in KILOGRAMES
 You can use a BALANCE
 VOLUME
 The space that an object occupies
 It is measured in LITRES
 You can use a GRADUATED RECIPIENT

3. PROPERTIES OF MATTER
 Fragility – The glass is fragil. (glass of water). It is very easy to break.
 Resistance – The wood and the iron are resistant materials. It is difficult to break.
 Conductor – Metal is conductor. It transports the heat.
 Non – conductor – Wood is non conductor. It doesn’t transport the heat.
 Elasticity - A hairband is elastic. It can be deformed, and then recover the initial position.
 Transparence – The glass is transparent. (the window). You can look through the window.

4. QUESTIONS
 What property of matter is measured with litres?
 What property of matter is measured with a balance?
 What property of matter does the glass have?
 What property of matter does the Wood have?
