K.1.1.A

Objects, and the materials they are made of, have properties that can be used to describe and classify them

K.1.1.A.a

Describe physical properties of objects (i.e., size, shape, color, mass) by using the senses, simple tools (e.g., magnifiers, equal arm balances), and/or nonstandard measures (e.g., bigger/smaller; more/less)

K.1.1.A.b

Identify materials (e.g., cloth, paper, wood, rock, metal) that make up an object and some of the physical properties of the materials (e.g., color, texture, shiny/dull, odor, sound, taste, flexibility)

K.1.1.A.c

Sort objects based on observable physical properties (e.g., size, material, color, shape, mass)

K.1.2.A

Forms of energy have a source, a means of transfer (work and heat), and a receiver

K.1.2.A.a

Identify the sounds and their source of vibrations in everyday life (e.g., alarms, car horns, animals, machines, musical instruments)

K.1.2.A.b

Compare different sounds (i.e., loudness, pitch, rhythm)

K.1.2.A.c

Identify the ear as a receiver of vibrations that produce sound

K.2.1.A

The motion of an object is described as a change in position, direction, and speed relative to another object (frame of reference)

K.2.1.A.a

Describe an objects position relative to another object (e.g., above, below, in front of, behind)

K.2.2.A

Forces are classified as either contact (pushes, pulls, friction, buoyancy) or non-contact forces (gravity, magnetism), that can be described in terms of direction and magnitude

K.2.2.A.a

Identify ways (push, pull) to cause some objects to move by touching them

K.2.2.A.b

Identify magnets cause some objects to move without touching them

K.3.1.D

Plants and animals have different structures that serve similar functions necessary for the survival of the organism

K.3.1.D.a

Observe and compare the structures and behaviors of different kinds of plants and animals

K.3.3.D

There is heritable variation within every species of organism

K.3.3.D.a

Identify that living things have offspring based on the organism's physical similarities and differences

K.4.1.A

All populations living together within a community interact with one another and with their environment in order to survive and maintain a balanced ecosystem

K.4.1.A.a

Describe how the seasons affect the behavior of plants and animals.

K.4.1.A.b

Describe how the seasons affect the everyday life of humans (e.g., clothing, activities

K.5.1.C

The atmosphere (air) is composed of a mixture of gases, including water vapor, and minute particles

K.5.1.C.a

Observe wind as moving air that is felt

K.5.2.F

Climate is a description of average weather conditions in a given area due to the transfer of energy and matter through Earths systems

K.5.2.F.a

Observe and describe daily weather: precipitation (e.g., snow, rain, sleet, fog), wind (i.e., light breezes to strong wind), cloud cover, temperature

K.5.2.F.b

Observe and describe the general weather conditions that occur during each season

K.6.1.A

The Earth, Sun, and Moon are part of a larger system that includes other planets and smaller celestial bodies

K.6.1.A.a

Observe and describe the presence of the Sun, Moon, and stars in the sky

K.6.1.A.b

Observe there are more stars in the sky than anyone can count and that they are scattered unevenly and vary in brightness

K.6.2.A

The apparent position of the Sun and other stars, as seen from Earth, change in observable patterns

K.6.2.A.a

Describe the Sun as only being seen in the daytime and appears to move across the sky from morning to night

K.6.2.B

The apparent position of the moon, as seen from Earth, and its actual position relative to Earth change in observable patterns

K.6.2.B.a

Observe the Moon can be seen sometimes at night and sometimes during the daytime

K.6.2.B.b

Observe that the Moon appears to change shape over the course of a month

K.6.2.C

The regular and predictable motions of the Earth and Moon relative to the Sun explain natural phenomena on Earth, such as day, month, year, shadows, moon phases, eclipses, tides, and seasons

K.6.2.C.a

Observe and describe the characteristics of the four seasons as they cycle through the year (summer, fall, winter, spring)

K.7.1.A

Scientific inquiry includes the ability of students to formulate a testable question and explanation, and to select appropriate investigative methods in order to obtain evidence relevant to the explanation

K.7.1.A.a

Pose questions about objects, materials, organisms and events in the environment

K.7.1.A.b

Conduct a simple investigation (fair test) to answer a question

K.7.1.B

Scientific inquiry relies upon gathering evidence from qualitative and quantitative observations

K.7.1.B.a

Make qualitative observations using the five senses

K.7.1.B.b

Make observations using simple tools and equipment (e.g., magnifiers/hand lenses, magnets, equal arm balances, thermometers)

K.7.1.B.c

Measure length and mass using non-standard units

K.7.1.B.d

Compare amounts/measurements

K.7.1.C

Scientific inquiry includes evaluation of explanations (laws/ principles, theories /models) in light of evidence (data) and scientific principles (understandings ) See CLEs: This concept became C, as the previous concept was eliminated and the GLEs were moved to this concept, and redundancy was eliminated

K.7.1.C.a

Use observations as support for reasonable explanations

K.7.1.C.b

Use observations to describe relationships and patterns and to make predictions to be tested

K.7.1.C.c

Compare explanations with prior knowledge
