describe that an unbalanced
force acting on an object
changes its speed, or direction of
motion, or both. Cognitive
Complexity: Moderate

observations or experiments,
identify variables, collect and
organize data, interpret data in
charts, tables, and graphics,
analyze information, make
predictions, and defend
conclusions. Cognitive
Complexity: High
SC.6.N.1.2 Explain why scientific
investigations should be
replicable. Cognitive Complexity:
High
SC.6.N.1.3 Explain the difference
between an experiment and
other types of scientific
investigation, and explain the
relative benefits and limitations
of each. Cognitive Complexity:
High
SC.6.N.1.4 Discuss, compare, and
negotiate methods used, results
obtained, and explanations
among groups of students
conducting the same
investigation. Cognitive
Complexity: High
SC.6.N.2.3 Recognize that
scientists who make
contributions to scientific
knowledge come from all kinds
of backgrounds and possess
varied talents, interests, and
goals. Cognitive Complexity: Low
 Identify gravity as the force that causes
objects to fall to Earth. (II, III)
 Design an experiment that demonstrates
the different properties of gravity. (III)
 Describe unbalance forces using a graphic
organizer. (IV)
Objectives below are from Quarter 1A
and should be embedded in this topic of
study.
 Explain the difference between an
experiment and other types of scientific
investigations.
 Use appropriate reference materials to
support scientific investigations of various
types, such as systematic observation or
experiments.
 Develop a hypothesis with one testable
independent variable.
 Distinguish between dependent and
independent variables and controls in a
variety of activities.
 Explain why scientific investigations
should be replicable.
 Conduct, discuss, and compare similar
investigations by working cooperatively in
groups.
 Collect and organize data in charts,
tables, and graphics.
 Give examples of how advances in
technology have affected scientific
theories and laws.
 Compare and contrast the terms that
describe examples of scientific knowledge
such as: theory, law, hypothesis, and
model.
 Distinguish between laws and theories by
understanding that laws describe the
what and theories explain the why.
 Explain why models are used in science to
observe processes that happen too
slowly, too quickly, or are too small or
vast for direct observation.

SC.6.N.3.1 Recognize and explain
that a scientific theory is a wellsupported and widely accepted
explanation of nature and is not
simply a claim posed by an
individual. Thus, the use of the
term theory in science is very
different than how it is used in
everyday life. Cognitive
Complexity: Moderate

Give examples of visual/physical,
mathematical, and conceptual models as
used in science.

SC.6.N.3.2 Recognize and explain
that a scientific law is a
description of a specific
relationship under given
conditions in the natural world.
Thus, scientific laws are different
from societal laws. Cognitive
Complexity: Moderate
SC.6.N.3.4 Identify the role of
models in the context of the
sixth grade science benchmarks.
Cognitive Complexity: Moderate
LA.6.2.2.3 The student will
organize information to show
understanding (e.g.,
representing main ideas within
text through charting, mapping,
paraphrasing, summarizing, or
comparing/contrasting);
LA.6.4.2.2 The student will
record information (e.g.,
observations, notes, lists, charts,
legends) related to a topic,
including visual aids to organize
and record information and
include a list of sources used;

reflection, and research.

measures of center (median
and/or mean) and variability
(interquartile range and/or mean

the data were gathered.

Relating the choice of
measures of center and
variability to the shape of the
data distribution and the context
in which the data were gathered.

taking measurements, or
