The content objectives and classroom connectors on this page were written by selected Tennessee teachers of science and are congruent with the CE/CE Content Topics listed for Second Grade Science. In addition, Standards and Benchmarks have been added to each classroom connector in compliance with the Four Components of Science Education derived from a unique curricular concept. The grade level presentations prepared by the CE/CE represent one of many ways the classroom connectors can be organized.

• Physical Science K-4

• Light, heat, electricity, and magnetism

  Light travels in a straight line unless it strikes an object Light can be reflected by a mirror, refracted by a lens, or absorbed by the object.

  Heat can be produced in many ways such as burning, rubbing, and mixing chemicals. The heat can move from one object to another by conduction.

• Physical Science K-4

• Position and motion of objects

NSES Content Standard

• Life Science K-4

• The characteristics of organisms

  Organisms have basic needs, which for animals are air, water, and food. -Organisms can only survive in environments in which they can meet their needs. The world has many different environments, and distinct environments support the life of different types of organisms.

  Each plant or animal has different structures which serve different functions in growth, survival, and reproduction. For example, humans have distinct structures of the body for walking, holding, seeing, and talking.

  The behavior of individual organisms is influenced by internal cues such as hunger and by external cues such as an environmental change. Humans and other organisms have senses that help them detect internal and external cues.

• Life Science K-4

• Life Cycles of organisms

  Plants and animals have life cycles that include being born, developing into adults, reproducing, and eventually dying. The details of this life cycle are different for different organisms.

  Plants and animals closely resemble their parents.

  Many characteristics of an organism are inherited from the parents of the organism, but other characteristics result from, an individual's interactions with the environment. Inherited characteristic include the color of flowers and the number of limbs of an animal. Other features such as the ability to play a musical instrument, are learned through interactions with the environment.

• Life Science K-4

• Organisms and their environments

  All animals depend on plants. Some animals eat plants for food. Other animals eat animals that eat the plants.

  CE/CE Concept Ea:

  • Animals reproduce by having young.

  CE/CE Content Objectives:

  • 0E1

    To understand some animal young are like the adult

  • 0E2

    To understand that some animals change as they grow

  • 0E3

    To understand how various animals reproduce and care for their young

  CE/CE Concept Eb:
  • Animals live in a variety of habitats and change with the seasons.

  CE/CE Content Objectives:

  • 0E4

    To understand animals have basic needs

  • 0E5

    To understand how seasonal changes affect animals

  CE/CE Concept F:

  • Each plant has different structures which serve different functions.

  CE/CE Content Objectives:

  • 0F1

    To understand the major parts of a plant

  • 0F2

    To understand how plants grow and change

NSES Content Standard

• Life Science K-4

• The characteristics of organisms

  Each plant or animal has different structures which serve different functions in growth, survival, and reproduction. For example, humans have distinct structures of the body for walking, holding, seeing, and talking.

• Science in Personal and Social perspectives K-4

• Personal health

  Different substances can damage the body and how it functions. Such substances include tobacco, alcohol, over-the-counter medicines, and illicit drugs. Students should understand that some substances such as prescription drugs can be beneficial but that any substance can be harmful.

  CE/CE Concept Ga:

  • There are similarities and differences among human beings.

  CE/CE Content Objectives:

  • 0G1

    To understand how people are alike and different

  CE/CE Concept Gb:
  • Human beings experience the world through their senses.

  CE/CE Content Objectives:

  • 0G2

    To understand the importance of the five senses

NSES Content Standard

• Science in Personal and Social perspectives K-4

• Types of resources

  Resources include those things that we get from the living and nonliving environment to meet the needs and wants of a population.

  Some resources include basic materials, such as air, water, and soil; some are produced from basic resources, such as food, fuel, and building materials; and some resources are nonmaterial, such as quiet places, beauty, security, and safety.

  The supply of many resources is limited. If used, those materials can be extended through recycling and decreased use.

• Science in Personal and Social perspectives K-4

• Changes in environments

  Environments include the space, conditions, and factors that affect individual's and population's ability to survive and quality of life.

  Changes in environments can be natural or influenced by humans. Some changes are good, some neither good nor bad, and some are bad. Pollution is a change in the environment that can influence the health, survival, or activities of organisms, including humans.

  Some environmental changes occur slowly, and others occur rapidly. -Students should understand the differences and consequences of changing environments in small increments over long periods of time and changes that occur in large increments in short periods.

NSES Content Standard

• Earth and Space Science K-4

• Properties of Earth materials

  Earth materials are solid rocks and soils, liquid water, and the gases of the atmosphere. These varied materials have different physical and chemical properties. These properties make them useful, for example, as building materials, as sources of fuel, or for growing the plants we use as food.

  Earth materials provide many of the resources humans use.

  Soils have properties of color and texture, capacity to retain water and ability to support the growth of many kinds of plants, including those in our food supply. Other Earth materials are used to construct buildings, make plastics and provide fuel for generating electricity and operating cars and trucks.

  The surface of the Earth changes. Some changes are due to slow processes, such as erosion and weathering, and some changes are due to rapid processes such as landslides, volcanoes, and earthquakes.

  Fossils provide evidence about the plants and animals that lived long ago and nature of the environment at that time.

  CE/CE Concept La:

  • Rocks are part of the earth's composition.

  CE/CE Content Objectives:
