Teacher(s):
Subject: Science
Grade band(s): HS
Number of students:
Unit: HS Chemical/Physical
Reactions
Setting:
Lesson Objective(s):
Objective 1: Students will identify elements contained in common objects.
Objective 2: Students will identify elements on the periodic table.
Objective 3: Students will identify and describe the uses of a periodic table.
Connections to the GBEs:
Standard(s):
Materials and Their Properties (1) 9.4 Explain that elements are pure substances that cannot
be separated by chemical or physical means. Recognize that compounds are pure substances
that can be separated by chemical means into elements.
Essence: Elements and Compounds
E1: Differentiate between elements and compounds.
E2: Identify characteristics of elements and compounds.
E3: Given examples, identify as elements or compounds.
Materials and Their Properties (1) 9.5 Classify various common materials as an element,
compound or mixture.
Essence: Elements, compounds, and mixtures
E1: Sort given materials as elements, compounds, or mixtures.
E2: Given examples, identify as an element or compound.
E3: Match mixtures or compounds with their component parts.
Materials and Their Properties 9.7 (1) Use the Periodic Table to identify an element's atomic
number, valence electron number, atomic mass, group/family and be able to classify the
element as a metal, non-metal or metalloid.
Essence: Period Table
E1: Use the Periodic Table to identify facts about elements.
E2: Given a Periodic Table with a key, identify if an element is a metal or nonmetal.
E3: Given the Periodic Table, match atomic number with the corresponding element.

Materials:
1. Common objects
2. Periodic Table and element flashcards
3. Element Riddles Worksheet
4. Compound and Element pictures
Activities:
1. Element-warm up: Begin with visual aids
and by introducing the term element- a
substance that cannot be broken down into
simpler parts or components. Explain how
common objects are made of elements. Show
students examples (jewelry-made up of Agsilver and Au-gold), liquid thermometer (Hgmercury), and (He-helium) in a balloon
(suggestions-use materials are easiest to
access). Next, introduce compound. A
compound is a substance formed when two
or more elements are chemically joined.
Water, salt, and sugar are examples of
compounds.
2. Periodic table: Explain to students the function
of a periodic table and how it can be used. Explain
that each box contains information about a different
atom. The periodic table shows all the atoms that
everything in the known universe is made from. It’s
kind of like the alphabet in which only 26 letters, in
different combinations, make up many thousands of
words. The 100 or so atoms of the periodic table, in
different combinations, make up millions of different
substances. Explain to students that an atom is the
smallest particle or “building block” of a
substance. An element is a substance made up of
all the same type of atom. For example, a piece of
carbon is made up of carbon atoms.
3. Interactive periodic table: Explain to
students the meanings of the different
numbers and letters in the boxes of the table,
paying particular to attention to the element
symbol and atomic number. Feel free to use
the periodic table provided or the interactive
periodic table at the following address:

4. Periodic table riddles activity: Students take a
look at riddles describing common objects and try to
figure out what elements they contain.
5. Element/compound sort: Show students
of materials and have them sort into (2)
categories: compound or element (can be
done individually, in pairs or whole group).
Warm-up:
Introduce students to elements by comparing them to the ingredients that make up a recipe. You can
show students a baked good (cookie, cupcake, etc.) that they are familiar with and ask them what are
the ingredients needed to make the item shown. Next, show students a piece of jewelry or another
object and ask them what materials (elements) they think that item contains. If needed show students
picture of elements (flashcards) to give them answer choices.

Closing Activity:
Element/compound sorting task. Have students talk about/identify the primary difference between an
element and compound (element- pure substance found on periodic table (contains only one type of
atom)/ compound is made up of more than (1) substance on the periodic table (contains more than 1
atom of different elements).
