5E Lesson Plan
Teacher: ____Nicholas Smith______________
Date: _________2/2/15-2/6/15_________
Materials: __Promethean Board/PowerPoint presentation, lab sheets/pencils, aluminum plates, boiled eggs, plastic scalpels,
small fishbowl, large orange, syrup, graham crackers, crushed crackers, student computers equipped with PowerPoint,
internet ___
Standards: ___MS 2010 Science Frameworks: 4. Describe the Earth’s System in terms of its position to objects in the universe,
structure and composition, climate, and renewable and nonrenewable resources.___
Objectives: ___The students will be able to describe the structure of the Earth and explain the differences of each layer of the
Earth. ____
Differentiation Strategies: ___ Lecture (Auditory), Small Group, Large Group, Manipulatives (Visual, Kinesthetic),
PowerPoint/Slides (Visual), Technology Assignment (Visual, Kinesthetic), Individualized Instruction ___
ENGAGEMENT:
Using a model of the inner Earth, TTW pre-assess the students on the layers of the Earth. As TT points to different areas of the
planet’s interior, TSW write their answers on a slip of paper. After they are collected, TTW state the correct answers.
Assessment: Pre-Assessment to gage TS prior knowledge.
EXPLORATION:
TTW place the students in groups of three. The students will receive an aluminum plate, one hard-boiled egg, a plastic scalpel,
gloves, and goggles. TTW explain how an egg is a perfect model of the Earth’s interior. TSW be instructed to divide the egg and
examine one half closely. TSW complete a short lab sheet together that helps TS compare the egg with the Earth’s interior.
Sample worksheet question:
Notice how the shell of the egg is hard and brittle. It makes up about 2% of the egg’s mass. How is this similar in proportion and
form to the Earth’s crust?
Assessment: Worksheet to gage TS ability to visualize the Earth’s interior.
EXPLANATION:
Materials needed before lesson: small fishbowl, large orange, syrup, graham crackers, crushed crackers
Beginning from the outside working in, TTW utilize PowerPoint and discuss the characteristics of the Earth’s crust, the Earth’s
mantle, and the Earth’s core. TTW describe the states of matter of each of the layers of the Earth. TTW diagram and discuss
the asthenosphere and the lithosphere.
After the initial lecture, TTW utilize the above materials to model both the structure and give a similar representation of the
state of matter of each layer of the Earth. This will provide a great visual that the students can recall.
For the display:
Approved January, 2013
TTW ask: Which of these would be a good representation of the Earth’s inner core? Why? (TTW place the orange in the fish
bowl to simulate the core.)
TTW ask: How are the viscosities of this syrup and magma similar? (TTW pour the syrup over the orange simulating the
viscosity of magma.)
TTW ask: How does the lithosphere move with the asthenosphere? (TTW place a layer of graham crackers on the syrup to
represent how the lithosphere floats on top of the asthenosphere.)
TTW ask: How does the crushed crackers represent the Earth’s crust? (TTW empty the crushed crackers on the graham crackers
explaining how the lighter material makes up the crust.)
Assessment: Large group Q and A session-informal
ELABORATION:
TSW be grouped into threes. Each group will have a student responsible for content, a student responsible for technology, and
a student responsible for time management and creativity. TSW be instructed to create a PowerPoint that gives a “tour” of the
Earth’s interior. TSW use information from the lesson, text, and internet to briefly explain each layer of the Earth. The required
slides are: crust, lithosphere, asthenosphere, mantle, inner core, and outer core. Required information will be a brief
description, the thickness of the layer, and the state of matter that the layer is in. Each slide must contain at least one picture
that adds to the visual effect and helps portray the appropriate feeling. A rubric will be used for grading.
Assessment: Formal-PowerPoint Tour graded with rubric
EVALUATION:
Lesson direction will be determined by the prior knowledge assessment. Students will be informally assessed during group
discussion and Q and A to determine what items need re-teaching and further explanation. The worksheet will help determine
the students’ ability to visualize a concept they cannot see. Using a rubric, TTW formally assess the students’ PowerPoint
assignment to determine understanding. The students will be able to describe the structure of the Earth and explain the
differences of each layer of the Earth with 90% accuracy.
