Grade Level(s)
4th grade
Length of Unit
2 weeks
Unit Summary
In this unit students will explore patterns of change in the earthʼs
layers through hands on experiments and activities, as well as case
studies of geologic phenomena. Students will learn about the layers
of the earth, volcano types, and volcanic activity. They will observe
the effects of geologic activity on human life as shown through case
studies. Throughout the unit, students will examine models of the
earth as well as models of volcanoes. They will observe how the
models represent real world situations, and will also identify
limitations of each model. Through reading, class discusion, math
and lab activities, the students will gain a better understanding of the
structure of the Earth.

layers of an apple.
2.Cut an apple in half at each group. Ask students to discuss the
differences observed.
3.Use the color diagram of the earth on the document camera and the
cut apple to describe similarities and differences between the two.
4. Ask what else could have been used to show differences in layers
(hard boiled egg, peach, golf ball, tennis ball, etc.).
5.Make connections to the apple and the picture on the doc camera and
label each layer.
6.Write the name of the layer on the picture on the doc camera as
students label their colored copy that will be placed in their science
notebook.

Lesson 2: Liquid Layers
Materials Needed:
Vegetable oil (1/2 cup per group)
Pancake Syrup (1/2 cup per group)
Water (1/2 cup per group)
Clear glass beaker or jar (1 per group)
1/2 cup measuring cup (1 per group)
Student worksheet: “Liquid Layers”
Demonstration Items:
"
-an unpeeled orange (or coconut)
"
-a jar of water
Layers of the Earth chart
Vocabulary: density
Essential Questions:
1. What is density?
2. Why and how do the densities of vegetable oil, water, and pancake syrup form layers when
mixed together?
Activity
Description of Activities and Setting
Focus/Review
During this activity, students use the scientific method to develop an
understanding of the concept of density and relate that concept to the
development of layers inside Earth.
Objective
•The student will use the scientific method to determine the relative
densities of vegetable oil, water, and pancake syrup.
•The student will learn how and why these liquids, when mixed together,
form layers.
•The student will relate the concept of liquid layers to layers inside Earth.
Teacher Input
The teacher will demonstrate the concept of density. Take a golf ball and
a ping pong ball. Both are about the same size or take up the same
volume. However, one is much heavier (has more mass) than the other.
The golf ball has its atoms much more closely packed together than the
ping pong ball. Thus, the golf ball is denser. The teacher will finally
explain the “Liquid Layers” lab.
AndersonElizabeth
Thursday, January 3, 2013 3:24:15 PM ET
Exploration/
Engagement Activities
1.Put an unpeeled orange in a jar of water. Explain that the orange floats
because it is less dense than water. Explain that density is the ratio of the
mass of a substance to its volume. All matter has density. Peel the orange
and return it to the jar of water. It will sink because without the peel, their
orange is more dense than water. Ask students what this experiment
demonstrates about the density of an orange peel (The orange peel is
less dense than water).
2.Divide students into groups. Distribute the Student Worksheet: “Liquid
Layers.”
3.Explain that vegetable oil, pancake syrup, and water each have a
different density. Ask students to predict which liquid is the most dense
and which is the least dense, and record their predictions in the
“Hypothesis” section “Liquid Layers.”
4.Distribute supplies and explain that students will do an experiment to
determine the relative densities of the three liquids. Ask students to use
the instructions on the worksheet to perform the experiment.
5. After students have completed the experiment procedure and recorded
the data, explain that the liquids have formed into layers according to
their relative density.
6. Ask students which liquid is the most dense. Explain that one can tell
that the syrup is the most dense because it rests at the bottom of the jar.
Ask students which liquid is the least dense. Explain that one can tell that
the vegetable oil is the least dense because it floats on top of the jar.
7. Ask students to complete the Analysis of Data and Conclusion sections
of the student worksheet.
8. Ask students to participate in a brainstorm discussion about how the
liquid layers are similar to the layers inside Earth.
9. Help students understand that the most dense material inside the Earth
rests in the core, and that the least dense material “floats” on top of the
mantle as the crust.
10. Ask students to complete the Further Questions section of “Liquid
Layers” and fill in the Layers of the Earth chart.
Assessment
The student will turn in their “Liquid Layers” worksheet after the lab is
complete.

Lesson 3 - What is the structure of a volcano?
Materials Needed:
tube of toothpaste with lid,
one pin
ICE chart
“Inside a Volcano model” chart
Vocabulary: magma, magma chamber, lava, vent, fissure, gas, ash, erupt
Essential Question: What does the inside of a volcano look like?
Activity
Description of Activities and Setting
Focus/Review
Watch the short video at http://studyjams.scholastic.com/
studyjams/jams/science/rocks-minerals-landforms/
volcanoes.htm . Afterwards, focus the lesson by asking the
essential question: What does the inside of a volcano look
like?
Objective
The students will be able to label a diagram of the inside of
a volcano.
Teacher Input
The teacher will use a tube of toothpaste to introduce the
structure of a volcano.
Show students the ICE chart.
Show students a tube of toothpaste. Ask: What happens
when you squeeze the container of toothpaste?
(Toothpaste will come out.) Demonstrate this action.
Ask: What would happen if you left the cap on and
squeezed the container? (The toothpaste would build up
pressure and explode when released.)
Explain this is what happens to a volcano when it erupts.
Magma collects in a chamber deep inside the earth. As
more magma enters the chamber, the pressure increases
until finally the magma pushes in surrounding rock, and
opens cracks in the earth at weak spots. Eventually, one of
the cracks opens all the way to the surface of the earth.
Volcanoes release built up pressure from inside the earth,
just like taking the cap off a tube of toothpaste.
Leave the cap on the toothpaste. Students should imagine
that the tube is the surface of the earth and the toothpaste
is hot, melted magma underground.
Flatten the toothpaste on the demonstration table. Use a
pin to make a tiny hole near the bottom. Ask: What does
the hole represent? (A volcanoʼs opening)
Press down on the tube near the cap to represent magma
oozing out of a volcano.

Activity
Description of Activities and Setting
Focus/Review
Teacher will shake up a coke can while she she asks what the
students think might happen. She opens the can and it squirts out.
This facilitates a discussion and allows teacher to assess prior
knowledge of gas pressure.

makes it perforated), show a slitted lid (explain what makes it slit).
Explain that we will come back to the “Type of Volcano that would
result” later in the unit. Review the terms Conrolled Variable,
Manpulated Variable, and Responding Variable. Monitor the class as
students investigate and encourage analysis and conclusion.
