Oklahoma State Standards for Science: Grade 7

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. Identify qualitative and/or quantitative changes given conditions (e.g., temperature, mass, volume, time, position, length, etc.) before, during, and after an event. 16
Suggested Titles for Oklahoma Science State Standard 1.1.

1.2. Use appropriate tools (e.g., metric ruler, graduated cylinder, thermometer, balances, spring scales, stopwatches, etc.) when measuring objects, organisms, and/or events. 58
Suggested Titles for Oklahoma Science State Standard 1.2.

1.3. Use appropriate System International (SI) units (i.e., grams, meters, liters, degrees Celsius, and seconds); and SI prefixes (i.e., micro-, milli-, centi-, and kilo-) when measuring objects, organisms, and/or events. 58
Suggested Titles for Oklahoma Science State Standard 1.3.

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.

4.3. Evaluate data to develop reasonable explanations, and/or predictions. 57
Suggested Titles for Oklahoma Science State Standard 4.3.

4.4. Accept or reject hypotheses when given results of an investigation. 16
Suggested Titles for Oklahoma Science State Standard 4.4.

4.5. Communicate scientific procedures and explanations. 16
Suggested Titles for Oklahoma Science State Standard 4.5.

OK.5. Science Processes and Inquiry: Inquiry: 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.

5.1. Use systematic observations, make accurate measurements, and identify and control variables. 5
Suggested Titles for Oklahoma Science State Standard 5.1.

5.2. Use technology to gather data and analyze results of investigations. 46
Suggested Titles for Oklahoma Science State Standard 5.2.

5.3. Review data, summarize data, and form logical conclusions. 9
Suggested Titles for Oklahoma Science State Standard 5.3.

5.4. Formulate and evaluate explanations proposed by examining and comparing evidence, pointing out statements that go beyond evidence, and suggesting alternative explanations. 9
Suggested Titles for Oklahoma Science State Standard 5.4.

OK.1. Physical Science: Properties and Physical Changes in Matter: Physical characteristics of objects can be described using shape, size, and mass whereas the materials from which objects are made can be described using color and texture. The student will engage in investigations that integrate the standards and lead to the discovery of the following objectives:

1.1. Matter has physical properties that can be measured (i.e., mass, volume, temperature, color, texture, and density). Physical changes of a substance do not alter the chemical nature of a substance (e.g., phase changes of water and/or sanding wood). 15
Suggested Titles for Oklahoma Science State Standard 1.1.

1.2. A mixture of substances often can be separated into the original substance using one or more of the physical properties. 14
Suggested Titles for Oklahoma Science State Standard 1.2.

OK.2. Life Science: Structure and Function in Living Systems: Living systems at all levels of organization demonstrate the complementary nature of structure and function. The student will engage in investigations that integrate the process standards and lead to the discovery of the following objectives:

2.1. Living systems are organized by levels of complexity (i.e., cells, tissues, organs, and/or systems). 41
Suggested Titles for Oklahoma Science State Standard 2.1.

2.2. Specialized structures perform specific functions at all levels of complexity (e.g., leaves on trees and wings on birds). 31
Suggested Titles for Oklahoma Science State Standard 2.2.

OK.3. Life Science: Reproduction and Heredity: Reproduction is the process by which organisms give rise to offspring. Heredity is the passing of traits to offspring. All organisms must be able to grow, reproduce, and maintain stable internal conditions while living in a constantly changing external environment. The student will engage in investigations that integrate the standards and lead to the discovery of the following objectives:

3.1. Characteristics of an organism result from inheritance and from interactions with the environment. 42
Suggested Titles for Oklahoma Science State Standard 3.1.

3.2. Reproduction is essential for species survival. Individual organisms with certain traits are more likely to survive and produce offspring. 23
Suggested Titles for Oklahoma Science State Standard 3.2.

OK.4. Life Science: Behavior and Regulations: All organisms must be able to grow, reproduce, and maintain stable internal conditions while living in a constantly changing external environment. Behavioral response is a set of actions determined in part by heredity and in part by experience. The student will engage in investigations that integrate the standards and lead to the discovery of the following objectives:

4.1. Living organisms strive to maintain a constant internal environment (i.e., temperature regulation). 41
Suggested Titles for Oklahoma Science State Standard 4.1.

4.2. Living organisms have physical and/or behavioral responses to external stimuli (e.g., hibernation, migration, plant growth, etc.). 14
Suggested Titles for Oklahoma Science State Standard 4.2.

OK.5. Earth/Space Science: Structures of the Earth System: The earth is mostly rock, three-fourths of its surface is covered by a relatively thin layer of water, and the entire planet is surrounded by a relatively thin blanket of air, and is able to support life. The student will engage in investigations that integrate the standards and lead to the discovery of the following objectives:

5.1. Global patterns of atmospheric movement influence local weather such as oceans effect on climate. 10
Suggested Titles for Oklahoma Science State Standard 5.1.

5.2. Clouds, formed by the condensation of water vapor, affect local weather and climate. 13

OK.6. Earth/Space Science: Earth and the Solar System: The earth is the third planet from the sun in a system that includes the moon, the sun, eight other planets and their moons, and smaller objects, such as, asteroids and comets. The student will engage in investigations that integrate the standards and lead to the discovery of the following objectives:

6.1. Most objects in the solar system are in regular and predictable motion. Those motions explain such phenomena as the day, the year, phases of the moon, and eclipses. 11
Suggested Titles for Oklahoma Science State Standard 6.1.

6.2. Seasons result from variations in the amount of the sun's energy hitting the surface, due to the tilt of the earth's rotation on its axis and the length of the day. 4
