(A) identify and use patterns to describe phenomena
or design solutions;
(B) investigate and predict cause-and-effect relationships
in science;
(C) measure and describe the properties of objects
in terms of size and quantity;
(D) examine the parts of a whole to define or model
a system;
(E) identify forms of energy and properties of matter;
(F) describe the relationship between structure and
function of objects, organisms, and systems; and
(G) describe how factors or conditions can cause objects,
organisms, and systems to either change or stay the same.
(6) Matter and its properties. The student knows that
matter has physical properties that determine how it is described,
classified, and used. The student is expected to:
(A) classify matter by observable physical properties,
including texture, flexibility, and relative temperature, and identify
whether a material is a solid or liquid;
(B) conduct a descriptive investigation to explain
how physical properties can be changed through processes such as cutting,
folding, sanding, melting, or freezing; and
(C) demonstrate that small units such as building blocks
can be combined or reassembled to form new objects for different purposes
and explain the materials chosen based on their physical properties.
(7) Force, motion, and energy. The student knows that
forces cause changes in motion and position in everyday life. The
student is expected to:
(A) explain how objects push on each other and may
change shape when they touch or collide; and
(B) plan and conduct a descriptive investigation to
demonstrate how the strength of a push and pull changes an object's
motion.
(8) Force, motion, and energy. The student knows that
energy is everywhere and can be observed in everyday life. The student
is expected to:
(A) demonstrate and explain that sound is made by vibrating
matter and that vibrations can be caused by a variety of means, including
sound;
(B) explain how different levels of sound are used
in everyday life such as a whisper in a classroom or a fire alarm;
and
(C) design and build a device using tools and materials
that uses sound to solve the problem of communicating over a distance.
(9) Earth and space. The student knows that there are
recognizable patterns in the natural world and among objects in the
sky. The student is expected to:
(A) describe the Sun as a star that provides light
and heat and explain that the Moon reflects the Sun's light; and
(B) observe objects in the sky using tools such as
a telescope and compare how objects in the sky are more visible and
can appear different with a tool than with an unaided eye.
(10) Earth and space. The student knows that the natural
world includes earth materials that can be observed in systems and
processes. The student is expected to:
(A) investigate and describe how wind and water move
soil and rock particles across the Earth's surface such as wind blowing
sand into dunes on a beach or a river carrying rocks as it flows;
(B) measure, record, and graph weather information,
including temperature and precipitation; and
(C) investigate different types of severe weather events
such as a hurricane, tornado, or flood and explain that some events
are more likely than others in a given region.
(11) Earth and space. The student knows that earth
materials and products made from these materials are important to
everyday life. The student is expected to:
(A) distinguish between natural and manmade resources;
and
(B) describe how human impact can be limited by making
choices to conserve and properly dispose of materials such as reducing
use of, reusing, or recycling paper, plastic, and metal.
(12) Organisms and environments. The student knows
that living organisms have basic needs that must be met through interactions
within their environment. The student is expected to:
(A) describe how the physical characteristics of environments,
including the amount of rainfall, support plants and animals within
an ecosystem;
(B) create and describe food chains identifying producers
and consumers to demonstrate how animals depend on other living things;
and
(C) explain and demonstrate how some plants depend
on other living things, wind, or water for pollination and to move
their seeds around.
(13) Organisms and environments. The student knows
that organisms have structures and undergo processes that help them
interact and survive within their environments. The student is expected
to:
(A) identify the roots, stems, leaves, flowers, fruits,
and seeds of plants and compare how those structures help different
plants meet their basic needs for survival;
(B) record and compare how the structures and behaviors
of animals help them find and take in food, water, and air;
(C) record and compare how being part of a group helps
animals obtain food, defend themselves, and cope with changes; and
(D) investigate and describe some of the unique life
cycles of animals where young animals do not resemble their parents,
including butterflies and frogs.
