Particle Theory1. Matter is composed of

particles.

2. Particles are in random motion.

3. Particles have energy (kinetic energy is energy of motion)

4. Particles can collide

5. Particles that collide can transfer energy.

Variables for Collisions1. Temperature

2. Energy

3. Particle size

4. Solids, liquids, gases

• The higher the temperature the more energy the particles have.

• Particles with more energy can have more collisions.

• More energy also means that particles can have more distance between them.

• Larger particles may be harder to move or may have less space between them.

• The spaces between particles are different depending on the state of matter (gases have more space).

Assessment: Diagram (with your name) Diagram one lab station. Use as much detail as possible.

•Include arrows (to show motion). Long arrows for more/faster motion and short arrows for slow.

•Use colored dots to represent particles.

• Label the diagram as to what is happening.

• Use appropriate science vocabulary such as: energy, temperature, collisions, phase of matter etc.
