The document outlines classroom rules and introduces concepts related to pure substances and the kinetic molecular theory of matter. It discusses the properties and behavior of particles, including how temperature affects particle motion and the distinction between elements and compounds. Examples are provided to illustrate these concepts and categorize various substances.

1. Classroom Rules:
Listen to your teacher.
Raise your hand to speak.
Be kind.
Listen and follow directions.
Respect everyone.
Work hard and do your best.

2. .
• Pure Substances
• Kinetic Molecular
Theory of Matter

3. .
1. What are atoms made of?
2. What does the particle model tell
us about matter?

4. 1. Imagine tiny particles representing
atoms or molecules. On your paper, draw
these "partying particles."
2. Use arrows on your cards to show the
movement of the particles.
Represent "cold" particles with slow, short
arrows on one side of the card
while "hot" particles with fast, long arrows.

5. Particles are constantly moving
(even in solids!), there are
spaces between particles,
and the speed of particle
motion increases with
temperature.

6. pure substances can be illustrated
using a conceptual model.

11. As the temperature rises, the higher the
particle velocity and the greater the space
occupied by the particles.
Substances generally expand as the
temperature rises.
Conversely, substances generally contract
when cooled.
How does particle motion relate to temperature?

12. · They affect the strength of forces
between particles.
· In gases, there are large spaces between
particles.
· In liquids, particles are closer together.
· The concept of small voids between
particles is relevant for solubility in other
substances.
Why are spaces between particles important?

14. Elements is a substance that cannot be
separated into simpler substance by chemical
change
Compounds are pure substances composed
of two or more different elements

15. Pairwork: Which shows an element/compound?
Situation A: Consider tearing a piece of tissue paper. Tissue
paper is made from smaller building blocks like cellulose
fibers. These fibers are themselves made of carbon,
hydrogen, and oxygen atoms linked together in a specific
way. Ripping the tissue separates these complex fibers, not
individual atoms.
Situation B: Imagine tearing a sheet of aluminum foil.
Aluminum foil is mostly made up of a single element called
aluminum (Al). When you rip it, you're separating tiny pieces
of aluminum, each still being aluminum.

16. What generalization can
you make for elements
and compounds? How can
you easily distinguish
them?

17. The following is a list of substances. Group them into
elements and compounds.
