1 5.1 The Classification of Matter Date: Warm up: Matter is anything that has mass and volume eg. Pure Substances Matter that only contains eg. Compounds A pure substance that consists of The elements are in and cannot be separated by physical means eg. Elements A pure substance that into anything simpler eg.

2 5.1 The Classification of Matter Mixtures Mixtures contain joined together, but their particles are not chemically joined eg. Heterogeneous Mixtures A mixture that is in its composition The particles of the substances exist in The components can be distinguished by eg. Homogenous mixtures Made up of substances that are mixed together eg. Summary: (two to three sentences summarizing this section) Self- Reflection Questions: 1. Describe one thing you learned about this topic today. 2. Describe one thing about this topic you want to learn in more detail.

3 5.2 Properties of Matter Date: Warm up: Physical Properties Physical properties may be They include things such as colour, melting point, boiling point, density, hardness, ductility, viscosity, malleability, luster Activity: Describe each of the above properties

4 5.2 Properties of Matter Chemical Properties Chemical properties describe the as it changes into a new substance They include things such as flammability, corrosion, and reactions with acid Activity: Describe each of the above Summary: (two to three sentences summarizing this section) Self- Reflection Questions: 1. Describe one thing you learned about this topic today. 2. Describe one thing about this topic you want to learn in more detail.

5 5.3 Changes in Matter Date: Warm up: Physical Change The substance before and after the change May cause a, but not in substance Eg. When substances can exist in states, changing from one state to another is a eg. Water à solid to liquid to gas Chemical Change Occurs when a substance changes into one or more with different properties Most chemical changes are E.g., Classify the following as a physical (P) or chemical (C) change. Sugar dissolves in water Silver tarnishes An apple is cut Heat changes water to steam Baking soda reacts to vinegar Iron rusts Milk sours Wood rots Pancakes cook Food is digested Ice melts Paper towel absorbs water

6 5.3 Changes in Matter Identifying Chemical and Physical Changes Physical Chemical Reversible New substances? Properties Energy change Summary: (two to three sentences summarizing this section) Self- Reflection Questions: 1. Describe one thing you learned about this topic today. 2. Describe one thing about this topic you want to learn in more detail.

7 5.4 Kinetic Molecular Theory Date: Warm up: Kinetic Molecular Theory 1) All matter is made up of tiny particles called 2) have different atoms 3) The particles are in 4) The more the particles have, the faster they move 5) The attraction between particles decreases with increase in Solids Particles are Particles are in place Attraction between particles is but as vibration increases Liquids Increase in energy from solids, increased amount of Particles are still can move freely within the container Attraction still quite high, but less than and with distance apart

8 5.4 Kinetic Molecular Theory Gases Increase in energy from liquids, increase in of particles Particle are very Particles into each other in a very rapid straight line motion between the particles, they are too far apart and moving Increase in energy causes an increase in Increase in speed and number of particles hitting the Change of State of Matter Summary: (two to three sentences summarizing this section) Self- Reflection Questions: 1. Describe one thing you learned about this topic today. 2. Describe one thing about this topic you want to learn in more detail.
