What is an example of a substance that can be found in all 3 states of matter?
Water
True or False. Energy can easily pass through an insulator.
False. It's not so easy!
What is the term?
Cannot be broken down into any other substance.
New substance
Could also be pure substance but has to be made of the same type of atoms/particles
Photosynthesis is an example of a _____________.
Chemical reaction
Give an example of a solution and mixture (not already mentioned).
Mixture- legos, m&Ms, beans and rice, etc.
What is the amount of matter in an object called?

True!
How do you know if a chemical reaction has taken place? List at least two ways you would know.
Color change, gas production, temperature change (physical properties change) A new substance is formed!
What is the term?
A substance that only contains one type of atom or particle and cannot be broken down into any other.
Pure substance
How can you separate a solution?
Evaporation
Provide an example of each: solid, liquid and gas
Liquid: water
Gas: oxygen

How would you know if an object has a density higher than water?
It would sink! If it was less, it would float!
True or False. A new substance is formed when salt dissolves into water.
False! It's a mixture because it can be separated through evaporation.
Provide a definition for a mixture and a definition for a solution.
Solution: When one or more substances dissolve into another. It can only be separated through evaporation.
Mixture: Can be separated into individual parts and maintains its own properties.
Explain the differences between a solid, liquid and gas.
Solids have a definite shape and volume. Liquids have a definite volume but take the shape of the container. Gases have no definite shape or volume.
True or False. Rubber is a good insulator and conductor.
False!
Why does the water in a metal pot start boiling when it's on the stove?
The metal pot heats up and transfers heat to the water. The water gets so hot it starts boiling!
True or False. A new substance is created when burning wood and paper.
True! A gas is produced indicating a chemical reaction which forms a new substance, smoke!
