Oklahoma State Standards for Science: Grade 4

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 (e.g., mass, length, time, volume, temperature) using Systems International (SI) units (i.e., grams, milligrams, meters, millimeters, centimeters, kilometers, liters, milliliters, and degrees Celsius). 3
Suggested Titles for Oklahoma Science State Standard 1.1.

1.2. Compare and/or contrast similar and/or different characteristics (e.g., color, shape, size, texture, sound, position, change, etc.) in a given set of objects organisms or events. 3
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 objects, organisms, and/or events using two or more observable properties (e.g., simple dichotomous keys). 23
Suggested Titles for Oklahoma Science State Standard 2.1.

2.2. Arrange objects, organisms, and/or events in serial order (e.g., least to greatest, fastest to slowest, etc.). 4
Suggested Titles for Oklahoma Science State Standard 2.2.

OK.3. Science Processes and Inquiry: Experiment: Experimenting is a method of discovering information. It requires making observations and measurements to test ideas. The student will accomplish these objectives to meet this standard.

3.1. Ask questions about the world and formulate an orderly plan to investigate a question. 32
Suggested Titles for Oklahoma Science State Standard 3.1.

3.2. Evaluate the design of a scientific investigation. 32
Suggested Titles for Oklahoma Science State Standard 3.2.

3.3. Design and conduct a scientific investigation. 32
Suggested Titles for Oklahoma Science State Standard 3.3.

3.4. Recognize potential hazards and practice safety procedures in all science investigations. 32
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, other visual representations, and mathematical equations. The student will accomplish these objectives to meet this standard.

4.1. Report data using tables, line, bar, trend, and/or simple circle graphs. 12
Suggested Titles for Oklahoma Science State Standard 4.1.

4.2. Interpret data tables, line, bar, trend and/or simple circle graphs. 12
Suggested Titles for Oklahoma Science State Standard 4.2.

4.3. Make predictions based on patterns in experimental data. 32
Suggested Titles for Oklahoma Science State Standard 4.3.

4.4. Communicate the results of investigations and/or give explanations based on data. 32
Suggested Titles for Oklahoma Science State Standard 4.4.

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 different ways to investigate questions and evaluate the fairness of the test. 32
Suggested Titles for Oklahoma Science State Standard 5.1.

5.2. Use a variety of measurement tools and technology. 12
Suggested Titles for Oklahoma Science State Standard 5.2.

5.3. Formulate a general statement to represent the data. 32
Suggested Titles for Oklahoma Science State Standard 5.3.

5.4. Share results of an investigation in sufficient detail so that data may be combined with data from other students and analyzed further. 32
Suggested Titles for Oklahoma Science State Standard 5.4.

OK.1. Physical Science: Position and Motion of Objects: The position of a moving object can be described relative to a stationary object or the background. The student will engage in investigations that integrate the standards and lead to the discovery of the following objectives:

1.1. The position and motion of objects can be changed by pushing or pulling. The size of the change is related to the strength of the push or pull. 6
Suggested Titles for Oklahoma Science State Standard 1.1.

1.2. The motion of an object can be described by tracing and measuring its position over time. 6
Suggested Titles for Oklahoma Science State Standard 1.2.

OK.2. Physical Science: Electricity: Electricity in circuits can produce light. The student will engage in investigations that integrate the standards and lead to the discovery of the following objectives:

2.1. Some materials are conductors of electricity while others are insulators. 8
Suggested Titles for Oklahoma Science State Standard 2.1.

2.2. The flow of electricity is controlled by open and closed circuits. 8
Suggested Titles for Oklahoma Science State Standard 2.2.

OK.3. Life Science: Characteristics of Organisms: Each type of organism has structures that enable it to function in unique and specific ways to obtain food, reproduce and survive. The student will engage in investigations that integrate the standards and lead to the discovery of the following objectives:

3.1. Organisms can survive only in environments in which their needs can be met. 47
Suggested Titles for Oklahoma Science State Standard 3.1.

3.2. Living organisms can be classified using various characteristics (e.g., habitats, anatomy, behaviors, etc.). 16
Suggested Titles for Oklahoma Science State Standard 3.2.

3.3. Many observable characteristics of an organism, such as the color of flowers or the number of limbs on an animal, are inherited from the parents of the organisms. 8
Suggested Titles for Oklahoma Science State Standard 3.3.

OK.4. Elementary Earth/Space Science: Properties of Earth Materials: Earth materials consist of rocks, soils, water, and air. The student will engage in investigations that integrate the process standards and lead to the discovery of the following objectives:

4.1. The processes of erosion, weathering, and sedimentation affect Earth materials. 12
Suggested Titles for Oklahoma Science State Standard 4.1.

4.2. Fossils provide evidence about the plants and animals that lived long ago and the nature of the environment at that time (e.g., simulating the formation of fossils). 28
