Science Elementary School Programs - Fourth Grade

Science, as defined by the National Academy of Sciences, is the "use of evidence to construct
testable explanations and predictions of natural phenomena, as well as the knowledge
generated through this process."

Recurring themes are pervasive in sciences, mathematics, and technology. These ideas
transcend disciplinary boundaries and include patterns, cycles, systems, models, and change
and constancy.

The study of elementary science includes planning and safely implementing classroom and
outdoor investigations using scientific processes, including inquiry methods, analyzing
information, making informed decisions, and using tools to collect and record information,
while addressing the major concepts and vocabulary, in the context of physical, earth, and
life sciences. Districts are encouraged to facilitate classroom and outdoor
investigations for
at least 50% of instructional time.

In Grade 4, investigations are used to learn about the natural world. Students should
understand that certain types of questions can be answered by investigations and that
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. They have limitations and based on new discoveries
are constantly being modified to more closely reflect the natural world.

  • Within the natural environment, students know that earth materials have properties
    that are constantly changing due to Earth's forces
    . The students learn that the
    natural world consists of resources, including renewable and nonrenewable, and their
    responsibility to conserve our natural resources for future generations. They will also
    explore Sun, Earth, and Moon relationships. The students will recognize that our major
    source of energy is the Sun.
  • Within the living environment, students know and understand that living organisms
    within
    an ecosystem interact with one another and with their environment.
    The students will recognize that plants and animals have basic needs, and they are met
    through a flow of energy known as food webs. Students will explore how all living organisms
    go through a life cycle and that adaptations enable organisms to survive in their ecosystem.
