Student Expectations Bundled in Lesson
Noun=Underline Verb=Italicize
6.5 (A) Know that an element is a pure substance represented by chemical symbols
6.5 (B) Recognize that a limited number of the many known elements comprise the largest portion of solid
Earth, living matter, oceans, and the atmosphere
Most material things in the world are composed of different combinations of about 100 different elements.
Solid earth (crust): Hydrogen, Oxygen, Carbon,
Calcium, Potassium, Silicon, Magnesium,
Phosphorus, Sulfur, Aluminum, Sodium, Iron
Living matter: Hydrogen, Oxygen, Carbon,
Nitrogen, Calcium, Potassium, Silicon,
Magnesium, Phosphorus, Sulfur, Aluminum
Atmosphere: Oxygen and Nitrogen
Oceans: Hydrogen, Oxygen, Carbon, Calcium,
Potassium, Magnesium, Sulfur, Sodium, Chlorine
Objective/Key Understanding:
 Identify the symbol for a given element by using a periodic table of elements such as hydrogen, oxygen, iron
 Compare and contrast the elements found in the living and nonliving parts of the biosphere.
Closing Product/ Question/ Informal Assessment:
 Complete a Frayer Model to define
‘element’ as a pure substance represented by a symbol on the periodic table.

Activity: Provide samples of common items such as sugar, brown sugar, salt. Water, colored water, rocks, aluminum foil, orange juice, etc. Ask student to record observations of each sample (stations or rotate items) the classification of the sample (pure substance or mixture) and their evidence or justification.
6.5 A and B
- Bring in real life examples of elements for the students to see such as gold, silver, and aluminum
