UNIT 1:
Interactions

Unit Topic/ Length:



This unit uses the topic of the structure of the Earth and Scientific Method to
teach students to write explanations through an expository essay. This 10
week unit contains a series of interim
assessments that build in complexity,
culminating with an essay that will be presented written in the classroom.

Essential Question:


Why
are
interactions
im
portant
?

Big Ideas/ Enduring Understandings



Through the process of scientific
investigation we
can answer
questions, solve problems and
provide sound explanation for the
world around




Understanding interactions
happening among components of
air, water and land, provides
understanding of events that occur
in the planet.

Guiding Questions

1.

What are
scientific investigations?

2.

What are interactions?

3.

How the steps of the scientific
method will help me understand
the structure of the Earth?

4.

What are the different views of the
Earth?

5.

What is the lithosphere made of?

6.

How weathering and erosion
influence ch
ange over time?

7.

What evidence supports the
hypothesis of the continental drift?

8.

How will I communicate my
scientific explanations?

9.

What are your strengths and
struggles in learning scientific
skills and processes?


10. What goals can I set to improve




my learning in the next unit?

ASSESSMENT EVIDENCE


Authentic Performance
Task(s):


Alignme
nt to NYS common Core Standards for
Literacy:

Students will work in groups
to…




Students
will read and interpret
data, searching for evidence that
supports a claim that explains


How does,


[Air, water, plate movement]


change
the structure of

Earth
over time?


After conducting secondary
research, students will write an
expository essay,
introducing the
topic of Interactions that change
the Structure of Earth,
supported by evidence from text
and data. This evidence will be
further discussed through the
essay, using domain

specific key
terms when appropriate through
well chosen and relevant

facts,
details and examples that will
help the reader clearly
understand the purpose of
understanding the structure of
Earth.

Literary Genre: Expository Text


expository essay



an essay that gives information or explains
something real.


expository
” comes from the word:





expound


(
to give a detailed statement
), which comes
from:

1.

the prefix ex
-

(meaning
outside
)

2.

plus the base word for the Latin verb (
to place
).


expound
” is similar to the word:




explain
” (
to make plain; define
), which comes from:

1.

the prefix ex
-

(meaning
outside
)

2.

plus the base word for the Latin verb (
to make
clear
).


Elements of Expository Writing



It’s purpose is to share information with the reader.



It often includes facts about real people and events.



The information is usually presented in a straightforward way
.



The events are often presented in the order in which they happened
(chronologically).



It may be organized by topics and sometimes includes headers.



It may include diagrams, photographs, maps, graphs or illustrations to
hope the reader understand the subj
ect better.



The factual information can be checked by referring to other sources.

How to Write an Expository Essay by Yourself


The Steps

1.

You receive an assignment to write about a subject (the
main topic
).

2.

You do a quick investigation to
decide what to

write

about.

Talk to friends and family. Look on the internet. Look in the
library for books on the subject. Ask a librarian for help.

3.

You
decide what sub
-
topics

are important to include to
best explain

your subject.

4.

You
create the

essay
outline
.

5.

You do

research and write

details about the sub
-
topics. Include
pictures and graphs if appropriate.

6.

You
organize the sub
-
topics

according to the outline.

7.

You
write a rough draft

from research notes. After you
proofread it
,
give it to the teacher to che
ck for errors.

8.

You
write the final draft

from the edited rough draft.

9.

You put a
nice cover

on the essay with pictures (
illustrations
), a
title
,
and
credits
.
