What is a liquid
What did we learn about the different liquids when poured into the water glass, even when they were poured in a different order.

This type of matter takes the shape of the container, with particles that bounce around quickly
What is gas
When we conducted the candle experiment, explain what happened to cause the changes in matter when heated and cooled.
What is the heat changed the solid to a liquid and the cooling changed the liquid to a solid.
When matter changes from one state to another, it mass _________
What is stays the same
The boiling point of what is _____ degrees celcius
The particle model of matter states that when the temperature of matter increases the particles

Explain why the string tied around the balloon in the freezer no longer fit when it was taken out.
What is the air molecules contracted taking up less space, causing the balloon to shrink
What is density
Architects must allow for ____________ to ensure the _________ of a structure.
The particle model of matter states that when particles move faster, the space
The type of energy that causes a change in matter, or causes particles of matter to move faster or slow down is known as

Unlike weight, this property of an object remains the same no matter where it is in the universe.
What is mass
Explain why the liquid in thermometers rises and falls as the temperature increases and decreases
What is the particles expand causing the liquid to take up more space, and contract when it is cold, causing the liquid to take up less space.
