New Mexico Standards for Second Grade Science

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. Conduct simple investigations (e.g., measure the sizes of plants of the same kind that are grown in sunlight and in shade).
I-A.2a. Use tools to provide information not directly available through only the senses (e.g., magnifiers, rulers, thermometers).
I-A.3a. Make predictions based on observed patterns as opposed to random guessing.
I-A.4a. Follow simple instructions for a scientific investigation.

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

I-C.1a. Record observations on simple charts or diagrams.
I-C.2a. Measure length, weight, and temperature with appropriate tools and express those measurements 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. Observe that the phase of the moon appears a little different every day but looks the same again after about four weeks.
II-A.2a. Observe that some objects in the night sky are brighter than others.
II-A.3a. Know that the sun is a star.

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

II-B.1a. Know that rocks have different shapes and sizes (e.g., boulders, pebbles, sand) and that smaller rocks result from the breaking and weathering of larger rocks.
II-B.2a. Understand that rocks are made of materials with distinct properties.
II-B.3a. Know that soil is made up of weathered rock and organic materials, and that soils differ in their capacity to support the growth of plants.
II-B.4a. Recognize the characteristics of the seasons.

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-B. Know that living things have similarities and differences and that living things change over time.

II-B.1a. Explain that stages of the life cycle are different for different animals (e.g., mouse, cat, horse, butterfly, frog).
II-B.3a. Observe how the environment influences some characteristics of living things (e.g., amount of sunlight required for plant growth).

II-C. Know the parts of the human body and their functions.

II-C.1a. Identify a variety of human organs (e.g., lungs, heart, stomach, brain).
II-C.2a. Know that various nutrients are required for specific parts and functions of the body (e.g., milk for bones and teeth, protein for muscles, sugar for energy).
II-C.3a. Identify the functions of human systems (e.g., respiratory, circulatory, digestive).

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. Observe that properties of substances can change when they are mixed, cooled, or heated (e.g., salt dissolves in water, ice melts).
II-A.2a. Describe the changes that occur when substances are heated or cooled and change from one state of matter to another (i.e., solid, liquid, and gas).

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

II-B.1a. Describe how heat can be produced (e.g., burning, rubbing, mixing some substances).
II-B.3a. Describe the usefulness of some forms of energy (e.g., electricity, sunlight, wind, sound) and how energy (e.g., heat, light,) can affect common objects (e.g., sunlight warms dark objects, heat melts candles).
II-B.4a. Observe that sound is made by vibrating objects and describe it by its pitch and loudness.
II-B.5a. Recognize that moving objects carry energy (kinetic energy).

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

II-C.1a. Describe how the strength of a push or pull affects the change in an object's motion (e.g., how a big or small push affects how high a swing rises).
II-C.2a. Observe that electrically charged materials and magnets attract and repel each other, and observe their effects on other kinds of materials.

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.5a. Know that science has discovered many things about objects, events, and nature and that there are many more questions to be answered.
