What does the principle of Conservation of Matter state?
What is, the principle that matter cannot be created or destroyed.
200
What is a mixture, and what is a solution?
(Describe a mixture and solution, and give 3 examples for each)
What is:
Mixture: A combination of two or more substances in which each keeps its own properties and both can be easily separated (Ex. Zaxby sauce, Trail Mix, Salad)
Solution: A liquid mixture in which one substance is mixed evenly throughout another substance. (Ex. Chick-fil-A sauce, Sweet Tea, Cheerwine)

What are examples of solvents and solutes?
Give 3 examples for each.
Solvent: Largest amount (the substance that things dissolve in)
The water in sugar water.
The milk in chocolate milk
The water in Sonic’s Cherry Limeade
The water in salty ocean water
Solute: Smallest amount (the substance that is being dissolved)
The sugar in sugar water
The chocolate in chocolate milk

Particles make up all matter, but we cannot see them with our eyes. Why do scientists need special tools like microscopes to study particles?
What is, they are too small to be seen with our own eyes
400
Which statement is true?
A. Cylinder 2 has a smaller volume than cylinder 1
B. Cylinder 3 has a larger volume than cylinder 1
C. Cylinder 4 has a larger volume than cylinder 3
D. Cylinder 2 has a smaller volume than cylinder 4
What is B. Cylinder 3 has a larger volume than cylinder 1

What is the difference between a physical change and a chemical change?
Physical Change: A change in the physical properties of matter, such as color, size, or shape.
Chemical change is forming a new substance, becoming something different than before.
400
What are ways to separate substances in different mixtures and solutions?
Give 3 different ways
What is: Chromatography, Sifting, Filtration, Evaporation, Flotation, and Magnetic Attraction
400
Why can't you trust atoms?
What is, because they make everything up.
500
How do the particles in each of the 3 states move around?
What is, the molecules in a Solid are compacted.
Liquid flows like a river. Gas is everywhere.
500
When scientists describe the physical properties of an object, what is the difference between observable properties and measurable properties?
What is:
Observable Properties - Properties that can be observed using our senses. (Color, scent, texture, etc.)
Measurable Properties- Properties that can be measured using different tools. (Length, mass, volume, etc.)
500
How do the states of matter change from one state to another?
Through change in temperature. Slowing down or speeding up the molecules
Melting, evaporation, and sublimation: Heating up
Freezing, condensation, and deposition: Cooling down
500
How can we affect dissolving for a solution? What are ways that we can change how fast the substance dissolves? Give all three.
What is:
Temperature change (temperature increases)
Particle size (smaller particles will dissolve faster)
Stirring (stirring can help it dissolve faster)
