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

  Vibrating objects produce sound. The pitch of the sound can be varied by changing the rate of vibration.

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 differ in many ways.

CE/CE Content Objectives:

• 4E1

  To understand distinguishing characteristics of selected vertebrates and invertebrates

• 4E2

  To understand the increasing complexity of cellular organization from cell to organism

CE/CE Concept Eb:
• Animals must be able to adapt to changes in order to survive.

CE/CE Content Objectives:

• 4E3

  To understand the means and characteristics of animal adaptation

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:
• The human body is composed of sensory organs which detect heat, light, and sound.

CE/CE Content Objectives:

• 4G1

  To understand the sensory organs and their function

• 4G2

  To understand the proper care of sensory organs

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

CE/CE Content Objectives:

• 4G3

  To understand the roles of exercise, sleep, cleanliness, and diet for proper growth and development

NSES Content Standard

• 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.

  An organism's patterns of behavior are related to the nature of that organism's environment, including the kinds and numbers of other organisms present, the availability of food and resources, and the physical characteristics of the environment. When the environment changes, some plants and animals survive and reproduce, and others die or move to new locations.

  All organisms cause changes in the environment where they live. Some of these changes are detrimental to themselves or other organisms, whereas others are beneficial.

  Humans depend on both their natural and their constructed environment. -Humans change environments in ways that can either be beneficial or detrimental for other organisms, including the humans themselves.

CE/CE Concept H:
• Living things perform specialized tasks in the environment.

CE/CE Content Objectives:

• 4H1

  To understand the differences among producers, consumers, and decomposers

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.
