Earth Science Lesson Plans
Mrs. Amos
Week: 8
UNIT 5 : Geologic Time
Week of : 1/4- 1/8/2016
Standard: (REG/ ADV): SC.7.E.6.4 (AA): Explain and give examples
of how physical evidence supports scientific theories that Earth
has evolved over geologic time due to natural processes.
SC.7.E.6.3: Identify current methods for measuring the age of Earth
and its parts, including the law of superposition and radioactive
dating.
Essential Content: how Earth has changed over time due to
natural processes
Learning Goals:
(1) Students will explain the current methods for measuring the age of the
Earth and its parts.

ESOL/ESE Modifications: 1,2,5,7,8
Assessments: Unit 5
Pre-Assessment: Learning Goal Self -Assessment
(before unit)- Unit Five- geologic time; Pre Test-pages
354-355 “getting ready to read” 9/10; Science Probes
Formative Assessment: bell ringer sheet summaries;
Thinking Maps; Learning goal self –assessment; reflection
sheets
Summative Assessment: End of unit test
Objectives:
(1) Students will decode science vocabulary using word parts.
(2) Students will explain the concept relative age and how
it relates to the Law of Superposition.
(3) Students will explain how radioactive dating is used to
date the Earth and its parts.
(4) Students will describe the concept “half- life”
in determining the age of the Earth.
(5) Students will review concepts related to Geologic Time.
Essential Questions:
(1) How do you “dissect” science words to determine their meaning?
(2) Contrast the scientific methods used to date the Earth and its features.
HOQ:
1. How do scientists know the age of rocks and fossils?
2. How has the Earth changed over time?
3. Relate the Law of superposition to something in your life.

Bell Ringer: Scientists can predict the age of fossils by looking at the age of
the______around them.
I Do: Introduce Earth Science “word parts “. Present list of word parts and their
meaning.
We Do: Discuss how to decode science words.
You Do: Using the word parts provided, produce “new” words (with at least 3 word
parts) new definitions and an illustration of the definition
Exit Ticket: Word parts help you ___________ (figure out the meaning of science
words).
Homework: Study 1st and 2nd nine week notes

Bell Ringer: Radioactive dating helps to determine the___________age of parts
the Earth.
I Do: Review learning scale for Unit 5. Present directions for launch a lab.
We Do: Participate in the activity; complete the three “think about it” questions.
You Do:
1. Inquiry Launch Lab pg. 342 - How can you describe your age?
2. Review of Fossils and Relative age and Absolute vs Relative Age
Exit Ticket: Half- life means_ _____________._
Homework: Study 1st and 2nd nine week notes
(1) (2) (1)
Bell Ringer: Absolute age is______________.
I Do: Present a review of natural processes that have changed Earth.
We Do: Have student pairs “draw” to see which “process” they will be reviewing for the
class.
You Do:
1. In pairs, using their textbooks as a reference, students will produce an informational
“poster” (extra-large sheet of paper) describing how their processes changes Earth over
time (weathering, erosion/deposition, plate tectonics, human activities(desertification,
deforestation, urbanization), volcanoes, earthquakes)
2. Student pairs will present their poster to the class.
Exit Ticket: Presentations
