Oklahoma State Standards for Science: Grade 2

OK.1. Science Processes and Inquiry: Observe and Measure: Observing is the first action taken by the learner to acquire new information about an object, organism, or event. Opportunities for observation are developed through the use of a variety of scientific tools. Measurement allows observations to be quantified. The student will accomplish these objectives to meet this standard.

1.1. Observe and measure objects, organisms, and/or events using developmentally appropriate nonstandard units of measurement (e.g., hand, paper clip, book, etc.) and Systems International (SI) units (i.e., meters, centimeters, and degrees Celsius). 3
Suggested Titles for Oklahoma Science State Standard 1.1.

1.2. Compare and contrast similar and/or different characteristics in a given set of simple objects, familiar organisms and/or observable events. 2
Suggested Titles for Oklahoma Science State Standard 1.2.

OK.2. Science Processes and Inquiry: Classify: Classifying establishes order. Objects, organisms, and events are classified based on similarities, differences, and interrelationships. The student will accomplish these objectives to meet this standard.

2.1. Classify a set of simple objects, familiar organisms, and/or observable events by observable properties. 2
Suggested Titles for Oklahoma Science State Standard 2.1.

2.2. Arrange simple objects, familiar organisms, and/or observable events in a serial order (e.g., least to greatest, tallest to shortest, etc.). 5
Suggested Titles for Oklahoma Science State Standard 2.2.

OK.3. Science Processes and Inquiry: Experiment and Inquiry: Experimenting is a method of discovering information. It requires making observations and measurements to test ideas. Inquiry can be defined as the skills necessary to carry out the process of scientific or systemic thinking. In order for inquiry to occur, students must have the opportunity to ask a question, formulate a procedure, and observe phenomena. The student will accomplish these objectives to meet this standard.

3.1. Ask a question about objects, organisms, or events in the environment. 16
Suggested Titles for Oklahoma Science State Standard 3.1.

3.2. Plan and conduct a simple investigation. 16
Suggested Titles for Oklahoma Science State Standard 3.2.

3.3. Employ simple equipment and tools; such as magnifiers, thermometer, rulers, etc.; to gather data. 16
Suggested Titles for Oklahoma Science State Standard 3.3.

3.4. Recognize potential hazards and practice safety procedures in all science activities. 16
Suggested Titles for Oklahoma Science State Standard 3.4.

OK.4. Science Processes and Inquiry: Interpret and Communicate: Interpreting is the process of recognizing patterns in collected data by making inferences, predictions, or conclusions. Communicating is the process of describing, recording, and reporting experimental procedures and results to others. Communication may be oral, written, or mathematical and includes: organizing ideas, using appropriate vocabulary, graphs, and other visual representations. The student will accomplish these objectives to meet this standard.

4.1. Interpret pictures, simple bar graphs, and/or tables. 15
Suggested Titles for Oklahoma Science State Standard 4.1.

4.2. Recognize and describe patterns, then make predictions based on patterns. 211
Suggested Titles for Oklahoma Science State Standard 4.2.

4.3. Communicate the results of a simple investigation using drawings, tables, graphs, and/or written and oral language. 31
Suggested Titles for Oklahoma Science State Standard 4.3.

OK.1. Physical Science: Properties and Interactions of Objects and Materials: Characteristics of objects can be described using physical properties such as size, shape, color, texture, or magnetism. Interactions change the position and motion of objects. The student will engage in investigations that integrate the process standards and lead to the discovery of the following objectives:

1.1. Objects can be described in terms of the materials of which they are made. Physical properties of materials can be changed by tearing, sifting, sanding, or pounding. 4
Suggested Titles for Oklahoma Science State Standard 1.1.

1.2. Motion and interaction of objects can be observed in toys and playground activities. 17
Suggested Titles for Oklahoma Science State Standard 1.2.

1.3. Magnets attract and repel each other and certain other materials. Magnetic force passes through materials such as paper, glass, and water. 7
Suggested Titles for Oklahoma Science State Standard 1.3.

OK.2. Life Science: Life Cycles and Organisms: Life cycles represent the stages an organism passes through from its own birth to the birth of the next generation. The student will engage in investigations that integrate the standards and lead to the discovery of the following objectives:

2.1. Plants and animals have life cycles that include developing into adults, reproducing, and eventually dying. The details of this life cycle are different for different organisms. 137
Suggested Titles for Oklahoma Science State Standard 2.1.

2.2. Generally, offspring resemble their parents. 53
Suggested Titles for Oklahoma Science State Standard 2.2.

OK.3. Earth/Space Science: Properties and Changes of Earth and Sky: Earth materials consist of rocks, soils, water, and air. The sun appears to move across sky in the same way every day. The student will engage in investigations that integrate the standards and lead to the discovery of the following objectives:

3.1. Earth materials can be used as resources (e.g., building materials and for growing plants). 24
Suggested Titles for Oklahoma Science State Standard 3.1.

3.2. The size and shape of shadows change at different times of the day. 2
Suggested Titles for Oklahoma Science State Standard 3.2.
