Jefferson County Science Scope and Sequence
Course:
4th Grade
Course Code:
5020010
Quarter: 1A
Topic(s) of Study: Thinking Like a Scientist
Bodies of Knowledge: Nature of Science
Big Idea(s): 1: The Practice of Science 2: The Characteristics of Scientific Knowledge 3: The Roles of
Theories, Laws, Hypotheses, and Models
Essential Questions: Why should evidence be used and cited to support scientific explanations? Why
could the results of investigations differ when scientists use similar methods and tools to study the natural
world? How does a scientific question determine the method of study?
NGSSS
SC.4.N.1.1 Raise questions
about the natural world, use
appropriate reference materials
that support understanding to
obtain information (identifying
the source), conduct both
individual and team
investigations through free
exploration and systematic
investigations, and generate
appropriate explanations based
on those explorations. Cognitive
Complexity: High
SC.4.N.1.2 Compare the
observations made by different
groups using multiple tools and
seek reasons to explain the
differences across
groups. Cognitive Complexity:
High
SC.4.N.1.3 Explain that science
does not always follow a rigidly
defined method ("the scientific
method ") but that science does
involve the use of observations
and empirical evidence.
Cognitive Complexity: Moderate
SC.4.N.1.4 Attempt reasonable

Develop questions to investigate the
natural world around us and write
them in a science notebook. (I, IV)
Describe how different approaches to
science are not always a rigid step by
step process, but can include
observations by analyzing a video. (I)
Discuss reasons why differences may
exist among various lab teams. (II)
Recognize that scientists question and
check each other’s work through role
play. (II, V)
Use proof (empirical evidence) to
support explanations and document in
a science notebook. (III, IV)
Conduct an investigation and record
observations in a science notebook.
(III, IV)
Compare and contrast observations
made by different groups using a
graphic organizer. (IV)
Describe the different types of models
(2D, 3D, computer simulations). (VII)
Explain why models are important but
are also limited in what they can
represent. (VII)
Explain why it is important to use lab
tools safely. (VIII)
Create a lab safety plan for the
classroom and describe why it is
important to have a lab safety

A. Lab Tools
1. Used by
scientists to
carry out
investigations
MACC.4.MD.1.1: Know relative sizes

system of units including km, m, cm;
kg, g; lb, oz.; l, ml; hr, min, sec.
Within a single system of
measurement, express
measurements in a larger unit in
terms of a smaller unit. Record
measurement equivalents in a two
column table. For example, know
that 1 ft is 12 times as long as 1 in.
Express the length of a 4 ft snake as
48 in. Generate a conversion table
for feet and inches listing the
number pairs (1, 12), (2, 24), (3, 36),
...
MACC.4.MD.2.4: Make a line plot to
display a data set of measurements
in fractions of a unit (1/2, 1/4, 1/8).
Solve problems involving addition
and subtraction of fractions by
using information presented in line
plots. For example, from a line plot
find and interpret the difference in
length between the longest and
shortest specimens in an insect
collection.
LACC.4.RI.1.3: Explain events,
procedures, ideas, or concepts in a
historical, scientific, or technical
text, including what happened and
why, based on specific information
in the text.
LACC.4.RI.2.4: Explain events,
procedures, ideas, or concepts in a

INTO NEXT TOPIC OF
STUDY
Now that we know that
we can study the natural
world through
observations,
investigations and
explanations, let’s use
these skills to help us
understand the patterns
in the sky and the
relationship between the
Sun, Earth, and Moon.
