Classification

Learning Goal By the end of the class, student will be

able to: understand the classification of matter

used by scientists classify various properties of matter

Minds On – What is it? Activity: Post-it Pile Up – What is it?

Look at the objects on your table and start to ask questions

Write down a question on your post-it note, then observe and make another.

Matter Has Many Forms What is Matter?

Anything that has mass or volume Can be solid, liquid, or gas… Mass = a measure of the quantity of

matter in an object Volume = measure of how big an object is

or how much space a fluid takes up.

Melting, Evaporation, Condensation, Freezing, Sublimation, & Deposition

The Particle Theory of Matter… Read the following article ‘The Particle

Theory of Matter’. Attempt to answer the following

questions: Who is Democritus and why is he

important? What did Democritus find out about

matter? Why do we care as scientists?

Classifying Matter ALL MATTER is made up of different

types or combinations of particles. E.g. gold & iron are both metals but they

have different characteristics Yellow & soft

v.s. Silver & hard

Classifying Matter Different types and combinations of

particles give every type of matter particular characteristics, or properties.

PROPERTY – is a characteristic that describes a substance.

Classifying Matter Pure Substance = made up of only one

kind of matter and has a unique set of propertiesPure

Substance

Element Compound

Element

A substance that cannot be broken down into any simpler substance by chemical means.

Compound

Is a pure substance that is made from two or more elements that are combined together chemically.

Quick Lab – Pennies & Water Let’s determine the special properties of

water… Lab: How many drops of water fit on a

penny? Use this lab to define the following terms;

cohesion and adhesion

Classifying Matter Mixture = a combination of pure substances.

Mixture

Heterogeneous Mixture

Mechanical Mixture

Suspensions

Homogeneous Mixture

Solution

Homework A Summary

of Matter Classification Read p.g.

143 and create a mind map of matter classification

Include examples for each.
