Physical Properties
What do we call the measurement of how heavy an object is?
Mass
What type of materials do magnets attract?
Metal like iron
What are the three states of water?
Solid, liquid, gas
What does the Law of Conservation of Mass state?
Mass is neither created nor destroyed
What is an example of a material that decays?
Food, animals, or leaves
What property describes the shape of an object?
Shape
What happens when two magnets are brought close together?
They can attract or repel each other.
What is one use for water in its solid state?
Ice for cooling drinks
If you have 5g of clay and you break it into smaller pieces, what is the total mass?
5g
What happens during the process of burning?
It turns materials into ash and gases, changing their properties.
What is the term for how much space an object takes up?
Volume
How can you demonstrate that magnets can repel each other?
By using two like poles (north-north or south-south).
How does water behave when it is heated?
It turns into steam (gas/ Water vapor)
How can you demonstrate the Law of Conservation of Mass using a balloon?
By inflating it and showing the mass remains the same.
How does rust form?
Rust is formed by the reaction of iron with oxygen and moisture.
Name a sense we use to perceive an object's color
Sight
What is the difference between attraction and repulsion in magnets?
Attraction pulls objects together; repulsion pushes them apart.
What are the properties of water in its gas state?
It is invisible and can fill any space.
Why does the mass of an object not change when it is divided into parts?
Because the total mass of the parts equals the whole.
Describe a change that happens when food is cooked
It undergoes chemical changes that alter its taste and texture.
What physical property indicates how rough or smooth a surface is?
Texture
Name a common household item that is magnetic.
Refrigerator magnets
Why is water important in its liquid state for living things?
It is essential for hydration and chemical reactions.
What happens to the mass of materials when they decay?
It is transformed into other materials but the total mass remains constant.
How do the characteristics of materials change during chemical reactions?
New materials with different properties are formed.
