Actions

L.2 Life Science

  • DCI.L.2.1 Hierarchical Organization

    • L.2.1 Students will demonstrate an understanding of the classification of animals based on physical characteristics.

  • DCI.L.2.2 Reproduction and Heredity

    • L.2.2 Students will demonstrate an understanding of how living things change in form as they go through the general stages of a life cycle.

      • L.2.2.1 Use observations through informational texts and other media to observe the different stages of the life cycle of trees (i.e., pines, oaks) to construct explanations and compare how trees change and grow over time.

      • L.2.2.2 Construct explanations using first-hand observations or other media to describe the life cycle of an amphibian (birth, growth/development, reproduction, and death). Communicate findings.

  • DCI.L.2.3 Ecology and Interdependence

    • L.2.3A Students will demonstrate an understanding of the interdependence of living things and the environment in which they live.

      • L.2.3A.1 Evaluate and communicate findings from informational text or other media to describe how animals change and respond to rapid or slow changes in their environment (fire, pollution, changes in tide, availability of food/water).

      • L.2.3A.2 Construct scientific arguments to explain how animals can make major changes (e.g., beaver dams obstruct streams, or large deer populations destroying crops) and minor changes to their environments (e.g., ant hills, crawfish burrows, mole tunnels). Communicate findings.

    • L.2.3B Students will demonstrate an understanding of the interdependence of living things.

  • DCI.L.2.4 Adaptations and Diversity

    • L.2.4 Students will demonstrate an understanding of the ways animals adapt to their environment in order to survive.

P.2 Physical Science

E.2 Earth and Space Science

  • DCI.E.2.8 Earth and the Universe

    • E.2.8 Students will demonstrate an understanding of the appearance, movements, and patterns of the sun, moon, and stars.

      • E.2.8.1 Recognize that there are many stars that can be observed in the night sky and the Sun is the Earth's closest star.

      • E.2.8.2 With teacher guidance, observe, describe, and predict the seasonal patterns of sunrise and sunset. Collect, represent, and interpret data from internet sources to communicate findings.

      • E.2.8.3 Observe and compare the details in images of the moon and planets using the perspective of the naked eye, telescopes, and data from space exploration.

      • E.2.8.4 With teacher support, gain an understanding that scientists are humans who use observations and experiments to learn about space. Obtain information from informational text or other media about scientists who have made important discoveries about objects in space (e.g., Galileo Galilei, Johannes Kepler, George Ellery Hale, Jill Tarter) or the development of technologies (e.g., various telescopes and detection devices, computer modeling, and space exploration).

      • E.2.8.5 Use informational text and other media to observe, describe and predict the visual patterns of motion of the Sun (sunrise, sunset) and Moon (phases).

      • E.2.8.6 Create a model that will demonstrate the observable pattern of motion of the Sun or Moon. Use an engineering design process to define the problem, design, construct, evaluate, and improve the model.

  • DCI.E.2.10 Earth's Resources

    • E.2.10 Students will demonstrate an understanding of how humans use Earth's resources.

      • E.2.10.1 Use informational text, other media, and first-hand observations to investigate, analyze and compare the properties of Earth materials (including rocks, soils, sand, and water).

      • E.2.10.2 Conduct an investigation to identify and classify everyday objects that are resources from the Earth (e.g., drinking water, granite countertops, clay dishes, wood furniture, or gas grill). Classify these objects as renewable and nonrenewable resources.

      • E.2.10.3 Use informational text and other media to summarize and communicate how Earth materials are used (e.g., soil and water to grow plants; rocks to make roads, walls or building; or sand to make glass).

      • E.2.10.4 Use informational text, other media, and first-hand observations to investigate and communicate the process and consequences of soil erosion.

      • E.2.10.5 With teacher guidance, investigate possible solutions to prevent or repair soil erosion.
