Describe an object you use everyday. What materials make up the object? Explain why those materials were used and how they were combined.
Answer may vary
What is Melt?
A change from solid to liquid
What are the properties of matter?
Shape, Size, Color, Texture, and Hardness
What is a physical property? Give me an example of each one
Mass, magnetism, sink or float, and temperature
How can cooling affect the states of matter?
When a liquid is cooled, it can change to a solid. This change of state is called freezing. When a gas is cooled, it can change into a liquid, this change of state is called condensation.
What is the purpose of combining materials?
People combine materials to make products harder, stronger, safer, and more useful
What is condensation?
The change from gas to liquid
Matter is what _______
Matter is anything that has mass and takes up space
Measured and mass
A puddle forms on a sidewalk, then dries up. This is evaporation in action. If you were to observe this process, how would you best describe it?

How would you measure and identify the physical properties of a large steel nail? Which tools would you use to measure the properties?
The large steel nail is gray, shiny, and rough. You can use a scale to weigh and a ruler to measure the height of the large steel nail.
How can heat affect liquids?
Heating a liquid can make it evaporate. Evaporation is a slow change from liquid to gas. If it gets hot enough, a liquid can boil.
How would you combine materials to make a stronger, safer, long-lasting house?
Brick, wood, and glass
Group objects based on ike properties
What are the states of matter? Give an example for each one
Liquid - Water
Gas - Air
Solid - Rock
When observing a hot drink on a cold day, several physical properties become apparent, what are they? How could you observe or measure each physical property?
Evaporation, condensation, water vapor, etc.
Draw a change in state caused by heating and cooling. Use arrows and labels to model what is happening
etc.
