Science Middle School Programs - Seventh Grade

Grade 6 science is interdisciplinary in nature; however, much of the content focus is on physical
science. National standards in science are organized as multi-grade blocks such as Grades 5-8
rather than individual grade levels. In order to follow the grade level format used in Texas, the
various national standards are found among Grades 6, 7, and 8. Recurring themes are pervasive
in sciences, mathematics, and technology. These ideas transcend disciplinary boundaries and
include change and constancy, patterns, cycles, systems, models, and scale.

The strands for Grade 7 include:
  • Scientific Investigations and Reasoning
    • To develop a rich knowledge of science and the natural world, students must become
      familiar with different modes of scientific inquiry, rules of evidence, ways of formulating
      questions, ways of proposing explanations, and the diverse ways scientists study the
      natural world and propose explanations based on evidence derived from their work.
    • Scientific investigations are conducted for different reasons. All investigations require
      a research question, careful observations, data gathering, and analysis of the data to
      identify the patterns that will explain the findings. Descriptive investigations are used to
      explore new phenomena such as conducting surveys of organisms or measuring the
      abiotic components in a given habitat. Descriptive statistics include frequency, range,
      mean, median, and mode. A hypothesis is not required in a descriptive investigation. On
      the other hand, when conditions can be controlled in order to focus on a single variable,
      experimental research design is used to determine causation. Students should experience
      both types of investigations and understand that different scientific research questions
      require different research designs.
    • Scientific investigations are used to learn about the natural world. Students should
      understand that certain types of questions can be answered by investigations, and the
      methods, models, and conclusions built from these investigations change as new
      observations are made. Models of objects and events are tools for understanding the
      natural world and can show how systems work. Models have limitations and based on
      new discoveries are constantly being modified to more closely reflect the natural world.
  • Matter and energy. Matter and energy are conserved throughout living systems. Radiant
    energy from the Sun drives much of the flow of energy throughout living systems due to
    the process of photosynthesis in organisms described as producers. Most consumers then
    depend on producers to meet their energy needs. Decomposers play an important role in
    recycling matter. Organic compounds are composed of carbon and other elements that
    are recycled due to chemical changes that rearrange the elements for the particular needs
    of that living system. Large molecules such as carbohydrates are composed of chains of
    smaller units such as sugars, similar to a train being composed of multiple box cars.
    Subsequent grade levels will learn about the differences at the molecular and atomic level.
  • Force, motion, and energy. Force, motion, and energy are observed in living systems
    and the environment in several ways. Interactions between muscular and skeletal systems
    allow the body to apply forces and transform energy both internally and externally. Force
    and motion can also describe the direction and growth of seedlings, turgor pressure, and
    geotropism. Catastrophic events of weather systems such as hurricanes, floods, and
    tornadoes can shape and restructure the environment through the force and motion
    evident in them. Weathering, erosion, and deposition occur in environments due to the
    forces of gravity, wind, ice, and water.
  • Earth and space. Earth and space phenomena can be observed in a variety of settings.
    Both natural events and human activities can impact Earth systems. There are
    characteristics of Earth and relationships to objects in our solar system that allow life to
    exist.
  • Organisms and environments
    • Students will understand the relationship between living organisms and their environment.
      Different environments support different living organisms that are adapted to that region of
      Earth. Organisms are living systems that maintain a steady state with that environment and
      whose balance may be disrupted by internal and external stimuli. External stimuli include
      human activity or the environment. Successful organisms can reestablish a balance through
      different processes such as a feedback mechanism. Ecological succession can be seen on a
      broad or small scale.
    • Students learn that all organisms obtain energy, get rid of wastes, grow, and reproduce.
      During both sexual and asexual reproduction, traits are passed onto the next generation.
      These traits are contained in genetic material that is found on genes within a chromosome
      from the parent. Changes in traits sometimes occur in a population over many generations.
      One of the ways a change can occur is through the process of natural selection. Students
      extend their understanding of structures in living systems from a previous focus on external
      structures to an understanding of internal structures and functions within living things.
    • All living organisms are made up of smaller units called cells. All cells use energy, get rid of
      wastes, and contain genetic material. Students will compare plant and animal cells and
      understand the internal structures within them that allow them to obtain energy, get rid of
      wastes, grow, and reproduce in different ways. Cells can organize into tissues, tissues into
      organs, and organs into organ systems. Students will learn the major functions of human
      body systems such as the ability of the integumentary system to protect against infection,
      injury, and ultraviolet (UV) radiation; regulate body temperature; and remove waste.
