What is Matter?
What is matter?
Anything that has mass and takes up space
What are the three states of matter?
Solid, liquid, gas
Which property tells us how heavy an object is?
Mass.
Melting ice?
Physical
What is the closest Country to Australia?
Papau New Guinea
Which one is NOT matter: air, water, sunlight or a rock?
Sunlight. It is energy, not matter
Which state of matter has a fixed shape and a fixed volume?
Solid
Which property describes how much space an object takes up?
Volume.
Burning piece of paper?
Chemical.
Where did Mr. Ferguson Previously live before moving to TI?
Redcliffe
A balloon is filled with air. Explain how this shows that air is matter.
Air takes up space inside the balloon and has mass.
What happens to the particles in a solid when it is heated?
The particles gain energy and vibrate faster.
Honey flows more slowly than water. What property explains this?
Viscosity.
A student cuts a piece of paper into small pieces. Explain why this is a physical change.
The paper changes size and shape, but no new substance is formed.
How many islands are in the Torres Strait? (to the nearest 10)
274
Two objects have the same volume but different masses. What does this tell us about the objects?
They have different densities. One has more mass in the same amount of space.
Why can a liquid change its shape but a solid usually cannot?
Liquid particles move past one another. Solid particles vibrate in fixed positions.
Which property describes adding water into concentrated juice?
Dilution
An iron nail begins to rust. Is this a P or C change? Explain
Chemical changes because a new substance (rust) forms.
What month was Mrs. Ferguson born in?
February
A student says "Gas is not matter because we cannot see it". Explain why the student is incorrect.
Gas has mass and takes up space, even though we cannot visually see it.
Ice melts into water. Explain what happens to the particles and whether the total mass changes.
Particles gain energy and move past each other. Total mass stays the same.
Two blocks have the same volume. One has a mass of 100g and the other 200g. Which block is denser? Explain
200g block because it has more mass in the same volume.
An egg is cracked into a frying pan and then cooks it. Identify the physical and chemical changes. Explain why.
Physical change: Cracking the egg (only the form changes)
Chemical change: cooking the egg (new form of egg is irreversible)
Who designed the Torres Strait Islander flag, and in what year was it adopted?
Bernard Namok, in 1992.
