Oklahoma State Standards for Science: Grade 6

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. 13
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.) to measure objects, organisms, and/or events. 48
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. 48

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, other visual representations, and mathematical equations. The student will accomplish these objectives to meet this standard.

4.1. Report data in an appropriate method when given an experimental procedure or data. 13
Suggested Titles for Oklahoma Science State Standard 4.1.

4.2. Interpret data tables, line, bar, trend, and/or circle graphs. 14
Suggested Titles for Oklahoma Science State Standard 4.2.

4.3. Evaluate data to develop reasonable explanation, and/or predictions. 48
Suggested Titles for Oklahoma Science State Standard 4.3.

4.4. Accept or reject hypotheses when given results of an investigation. 11
Suggested Titles for Oklahoma Science State Standard 4.4.

4.5. Communicate scientific procedures and explanations. 11
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. 35
Suggested Titles for Oklahoma Science State Standard 5.1.

5.2. Use technology to gather data and analyze results of investigations. 32
Suggested Titles for Oklahoma Science State Standard 5.2.

5.3. Review data, summarize data, and form logical conclusions. 20
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. 20
Suggested Titles for Oklahoma Science State Standard 5.4.

OK.1. Physical Science: Physical Properties 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, and texture). Changes in physical properties of objects can be observed, described, and measured using tools such as simple microscopes, gram spring scales, metric rulers, metric balances, and Celsius thermometers. 11
Suggested Titles for Oklahoma Science State Standard 1.1.

1.2. The mass of an object is not altered due to changes in shape. 11
Suggested Titles for Oklahoma Science State Standard 1.2.

OK.2. Physical Science: Transfer of Energy: Change from one form of energy to another (i.e., electrical energy to light energy). The student will engage in investigations that integrate the standards and lead to the discovery of the following objectives:

2.1. Energy exists in many forms such as, heat, light, electricity, mechanical motion, and sound. Energy can be transferred in various ways. 14
Suggested Titles for Oklahoma Science State Standard 2.1.

2.2. Electrical circuits provide a means of transferring electrical energy when heat, light, and sound are produced (e.g., open and closed circuits). 7
Suggested Titles for Oklahoma Science State Standard 2.2.

2.3. Electric currents and magnets can exert a force on each other. 7
Suggested Titles for Oklahoma Science State Standard 2.3.

OK.3. 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:

3.1. Cells are the building blocks of all organisms (both plants and animals). 18
Suggested Titles for Oklahoma Science State Standard 3.1.

3.2. Living systems are organized by levels of complexity (i.e., cells, organisms, and ecosystems). 99
Suggested Titles for Oklahoma Science State Standard 3.2.

OK.4. Life Science: Populations and Ecosystems: Populations consist of individuals of a species that occur together at a given place and time. All populations living together and the physical factor with which they interact compose an ecosystem. The student will engage in investigations that integrate the standards and lead to the discovery of the following objectives:

4.1. Organisms within an ecosystem are dependent on one another and on nonliving components of the environment. Some source of energy is needed for all organisms to stay alive and grow. Energy transfer can be followed in food chains and webs. 9
Suggested Titles for Oklahoma Science State Standard 4.1.

4.2. In all environments, organisms with similar needs may compete with one another for resources, including food, space, water, air, and shelter. Other relationships may be beneficial. 11

OK.5. Earth/Space Science: Structures of the Earth and the Solar 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. Earth has four main systems that interact: the atmosphere, the hydrosphere, the biosphere, and the geosphere. 4
