  4. identify parts that, when separated from the whole, may result in the part or the whole not working, such as cars without wheels and plants without roots;
  5. manipulate parts of objects such as toys, vehicles, or construction sets that, when put together, can do things they cannot do by themselves.

The student is expected to:

  1. observe, describe, and record changes in size, mass, color, position, quantity, time, temperature, sound, and movement;
  2. identify that heat causes change, such as ice melting or the Sun warming the air and compare objects according to temperature;
  3. observe and record weather changes from day to day and over seasons;
  4. observe and record stages in the life cycle of organisms in their natural environment.
(K.8) Science concepts. The student knows the difference between living organisms and nonliving objects.

The student is expected to:

  1. identify a particular organism or object as living or nonliving; and
  2. group organisms and objects as living or nonliving.
(K.9) Science concepts. The student knows that living organisms have basic needs.

The student is expected to:

  1. identify basic needs of living organisms;
  2. give examples of how living organisms depend on each other;
  3. identify ways that the Earth can provide resources for life.

Grade 1

(1.6) Science concepts. The student knows that systems have parts and are composed of organisms and objects.

The student is expected to:

  1. sort organisms and objects according to their parts and characteristics;
  2. observe and describe the parts of plants and animals;
  3. manipulate objects such as toys, vehicles, or construction sets so that the parts are separated from the whole which may result in the part or the whole not working; and
  4. identify parts that, when put together, can do things they cannot do by themselves, such as a working camera with film, a car moving with a motor, and an airplane flying with fuel.
(1.7) Science concepts. The student knows that many types of change occur.

The student is expected to:

  1. observe, measure, and record changes in size, mass, color, position, quantity, sound, and movement;
  2. identify and test ways that heat may cause change such as when ice melts;
  3. observe and record changes in weather from day to day and over seasons; and
  4. observe and record changes in the life cycle of organisms.
(1.8) Science concepts. The student distinguishes between living organisms and nonliving objects.

The student is expected to:

  1. group living organisms and nonliving objects; and
  2. compare living organisms and nonliving objects.
(1.9) Science concepts. The student knows that living organisms have basic needs.

The student is expected to:

  1. identify characteristics of living organisms that allow their basic needs to be met; and
  2. compare and give examples of the ways living organisms depend on each other for their basic needs.

Grade 2

(2.5) Science concepts. The student knows that organisms, objects, and events have properties and patterns.

The student is expected to:

  1. classify and sequence organisms, objects, and events based on properties and patterns; and
  2. identify, predict, replicate, and create patterns including those seen in charts, graphs, and numbers.
(2.6) Science concepts. The student knows that systems have parts and are composed of organisms and objects.

The student is expected to:

  1. manipulate, predict, and identify parts that, when separated from the whole, may result in the part or the whole not working, such as flashlights without batteries and plants without leaves;
  2. manipulate, predict, and identify parts that, when put together, can do things they cannot do by themselves, such as a guitar and guitar strings;
  3. observe and record the functions of plant parts; and
  4. observe and record the functions of animal parts.
(2.8) Science concepts. The student distinguishes between living organisms and nonliving objects.

The student is expected to:

  1. identify characteristics of living organisms; and
  2. identify characteristics of nonliving objects.
(2.9) Science concepts. The student knows that living organisms have basic needs.

The student is expected to:

  1. identify the external characteristics of different kinds of plants and animals that allow their needs to be met; and
  2. compare and give examples of the ways living organisms depend on each other and on their environments.

Grade 3

(3.8) Science concepts. The student knows that living organisms need food, water, light, air, a way to dispose of waste, and an environment in which to live.

The student is expected to:

  1. observe and describe the habitats of organisms within an ecosystem;
  2. observe and identify organisms with similar needs that compete with one another for resources such as oxygen, water, food, or space;
  3. describe environmental changes in which some organisms would thrive, become ill, or perish; and
  4. describe how living organisms modify their physical environment to meet their needs such as beavers building a dam or humans building a home.
(3.9) Science concepts. The student knows that species have different adaptations that help them survive and reproduce in their environment.

The student is expected to:

  1. observe and identify characteristics among species that allow each to survive and reproduce; and
  2. analyze how adaptive characteristics help individuals within a species to survive and reproduce.
(3.10) Science concepts. The student knows that many likenesses between offspring and parents are inherited from the parents.

  1. identify some inherited traits of plants; and
  2. identify some inherited traits of animals.

Grade 4

(4.5) Science concepts. The student knows that complex systems may not work if some parts are removed.
