Elements, Compounds and Mixtures
Activity10/15/09
Matter
The atoms and molecules that make up our surroundings.
Chemistry is the study of matter
We need to be able to describe what it’s made of, how it works and what it looks like!
So, where are we?
What we’ve learned…How to classify matter into
states: solid, liquid, gases. (the big picture)
Where we’re going…Taking a closer look – groups of
atoms and molecules
What we’re doing today
As scientists, we make decisions based upon what we observe (colors, changes, textures, etc.)
Today we’ll be using models to examine matter and how it interacts.
Our modelsEach group has a set of dishes filled
with beadsEach bead represents one atom!Each groups of beads represents a
compound – or a set of atoms bound together.
In groups we are going to complete a few tasks to discover different ways matter can be sorted
Do not open the petri dishes!
Part 1: Pure Substance vs. Mixture
Pure substance: all particles of matter are identical
Mixture: a physical blend of two or more pure substances in any proportion
Your group task: take 4 minutes to sort your petri dishes into two groups: pure substances and mixtures. Write the symbols from the petri dishes onto your worksheet according to how you grouped them.
MIXTURE NON-MIXTURE – PURE SUBSTANCE
ELEMENTS, COMPOUNDS, & MIXTURES ACTIVITYSORT DISHES INTO TWO GROUPS,
MIXTURES AND NON-MIXTURES.
Part 2: Elements vs. CompoundsPure substances can be classified into two sub-
categories:
Element: substances made from one type of atom
Compound: substances made from one or more types of atoms, chemically bound together
Your group task: take 4 minutes to list the pure substances you classified in Part 1, then categorize them into elements and compounds. Once you have sorted them, list the formulas from the petri dishes onto your worksheet in Part 2.
NON-MIXTURES – PURE SUBSTANCE
Elements Compounds
ELEMENTS, COMPOUNDS, & MIXTURES ACTIVITY
SORT PURE SUBSTANCE GROUP INTO TWO SUBGROUPS.
Part 3: Elements, Compounds and Mixtures
Group task: Based on the groups you just made, take 5 minutes to fill in the table in Part 3 on your worksheet with drawings of the samples and their formulas.
For example, was classified as a compound, so I would draw it in a box in the compound row of the table and write it’s symbol
MIXTURESNON-MIXTURES – PURE

ELEMENTS, COMPOUNDS, & MIXTURES ACTIVITY (Part 3)
What have we learned?Reflection: Take a minute to think about
something new that you’ve learned today.
Share it with a partner!
Matter can be categorized as a mixture or a pure substance
Pure substances can be further categorized as elements or compounds
But scientists don’t use pictures to describe matter – they use symbols!
Part 4: Describing mixtures and pure substances using codes
Look at the codes you wrote in part 1.
Group task: Take 3 minutes to discuss and answer the following questions on your worksheet in part 4
1. How are the mixture formulas different
from pure substance (non-mixtures) codes?
2. How do the codes relate to the objects in the dishes?
Part 5: Describing elements and compounds using codes
Look at the codes you used to describe pure substances in Part 2
Group task: take 3 minutes to discuss and answer the following questions on your worksheet in Part 5
1. How are the compound codes different from the element codes?
2. How do the codes relate to the objects in the dishes?
Part 6: Rules for writing formulas and codes!
Elements Compounds MixturesGold AuSodium NaCarbon CHydrogen H2

Look at the list of matter below, and the chemical formulas that chemists use to represent them
Group task: Take 5 minutes to write 4 rules for how chemical formulas are written. Think about• Why are some letters capitalized?• What do the small numbers represent and where are they
located?• What is the difference between the mixture codes and the
pure substance codes?• What information do formulas and codes tell us?
