NM.I. Scientific Thinking and Practice: Understand the processes of scientific investigations and use inquiry and scientific ways of observing, experimenting, predicting, and validating to think critically.

I-A. Use scientific methods to observe, collect, record, analyze, predict, interpret, and determine reasonableness of data.

I-A.1a. Make new observations when discrepancies exist between two descriptions of the same object or phenomenon to improve accuracy.
I-A.3a. Use numerical data in describing and comparing objects, events, and measurements.
I-A.4a. Collect data in an investigation and analyze those data.

I-B. Use scientific thinking and knowledge and communicate findings.

I-B.1a. Use a variety of methods to display data and present findings.
I-B.2a. Understand that predictions are based on observations, measurements, and cause-and-effect relationships.

I-C. Use mathematical skills and vocabulary to analyze data, understand patterns and relationships, and communicate findings.

I-C.1a. Use numerical data in describing and comparing objects, events, and measurements.
I-C.3a. Use various methods to display data and present findings and communicate results in accurate mathematical language.

NM.II. Content of Science: Earth and Space Science: Understand the structure of Earth, the solar system, and the universe, the interconnections among them, and the processes and interactions of Earth's systems.

II-A. Know the structure of the solar system and the objects in the universe.

II-A.1a. Describe the objects in the solar system (e.g., sun, Earth and other planets, moon) and their features (e.g., size, temperature).
II-A.2a. Describe the relationships among the objects in the solar system (e.g., relative distances, orbital motions).
II-A.3a. Observe that the pattern of stars stays the same as they appear to move across the sky nightly.
II-A.4a. Observe that different constellations can be seen in different seasons.

II-B. Know the structure and formation of Earth and its atmosphere and the processes that shape them.

II-B.1a. Know that Earth's features are constantly changed by a combination of slow and rapid processes that include the action of volcanoes, earthquakes, mountain building, biological changes, erosion, and weathering.
II-B.2a. Know that fossils are evidence of earlier life and provide data about plants and animals that lived long ago.
II-B.3a. Know that air takes up space, is colorless, tasteless, and odorless, and exerts a force.
II-B.4a. Identify how water exists in the air in different forms (e.g., in clouds and fog as tiny droplets; in rain, snow, and hail) and changes from one form to another through various processes (e.g., freezing/condensation, precipitation, evaporation).

NM.II. Content of Science: Life Science: Understand the properties, structures, and processes of living things and the interdependence of living things and their environments.

II-A. Know that living things have diverse forms, structures, functions, and habitats.

II-A.1a. Know that an adaptation in physical structure or behavior can improve an organism's chance for survival (e.g., horned toads, chameleons, cacti, mushrooms).
II-A.2a. Observe that plants and animals have structures that serve different functions (e.g., shape of animals' teeth).
II-A.3a. Classify common animals according to their observable characteristics (e.g., body coverings, structure).
II-A.4a. Classify plants according to their characteristics (e.g., tree leaves, flowers, seeds).

NM.II. Content of Science: Physical Science: Understand the structure and properties of matter, the characteristics of energy, and the interactions between matter and energy.

II-A. Recognize that matter has different forms and properties.

II-A.1a. Identify and compare properties of pure substances and mixtures (e.g., sugar, fruit juice).
II-A.2a. Separate mixtures based on properties (e.g., by size or by substance; rocks and sand, iron filings and sand, salt and sand).

II-B. Know that energy is needed to get things done and that energy has different forms.

II-B.1a. Understand that light is a form of energy and can travel through a vacuum.
II-B.2a. Know that light travels in a straight line until it strikes an object and then it is reflected, refracted, or absorbed.
II-B.3a. Measure energy and energy changes (e.g., temperature changes).

II-C. Identify forces and describe the motion of objects.

II-C.1a. Recognize that magnets can produce motion by attracting some materials (e.g., steel) and have no effect on others (e.g., plastics).
II-C.2a. Describe how magnets have poles (N and S) and that like poles repel each other while unlike poles attract.
II-C.3a. Observe that some forces produce motion without objects touching (e.g., magnetic force on nails).
II-C.4a. Describe motion on different time scales (e.g., the slow motion of a plant toward light, the fast motion of a tuning fork).

NM.III. Science and Society: Understand how scientific discoveries, inventions, practices, and knowledge influence, and are influenced by, individuals and societies.

III-A. Describe how science influences decisions made by individuals and societies.

III-A.1a. Describe how food packaging (e.g., airtight containers, date) and preparation (heating, cooling, salting, smoking, drying) extend food life and the safety of foods (e.g., elimination of bacteria).
III-A.2a. Know that science produces information for the manufacture and recycling of materials (e.g., materials that can be recycled and others that cannot [gasoline]).
