Oklahoma Standards for Fourth Grade Science

OK.E/SS. EARTH/SPACE SCIENCE

E/SS.4. Properties of Earth and Moon - The Earth and its Moon have specific properties. The student will engage in investigations that integrate the process standards and lead to the discovery of the following objectives:

E/SS.4.1. Earth materials consist of rock, soils, water, and air.
E/SS.4.2. The processes of erosion, weathering, and sedimentation affect Earth materials (e.g., earthquakes, floods, landslides, volcanic eruptions).
E/SS.4.3. Fossils provide evidence about the plants and animals that lives long ago and the nature of the environment at that time (e.g., the formation of fossils).
E/SS.4.4. The observable shape of the moon changes from day to day in a cycle that lasts about a month.

OK.LS. LIFE SCIENCE

LS.3. 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 process standards and lead to the discovery of the following objectives:

LS.3.1. Organisms can survive only in environments in which their needs can be met (e.g., food, shelter, air, reproduction, and water).
LS.3.2. Living organisms may be grouped by various characteristics or the environment in which they live (e.g., habitats, anatomy, behaviors).
LS.3.4. Energy from the Sun is passed to organisms through food chains.

OK.PS. PHYSICAL SCIENCE

PS.1. 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 process standards and lead to the discovery of the following objectives:

PS.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.

PS.2. Energy - Energy is the ability to do work or to cause a change in matter. Forms of energy include electricity, heat (thermal), light and sound. The student will engage in investigations that integrate the process standards and lead to the discovery of the following objectives:

PS.2.1. Electricity is the flow of electrical power or charge.
PS.2.1.a. The flow of electricity is controlled by open and closed circuits.
PS.2.2. Heat results when substances burn, when certain kinds of materials rub against each other, and when electricity flows through wires.
PS.2.2.a. Metals are good conductors of heat and electricity.
PS.2.2.b. Increasing the temperature of any substance requires the addition of heat energy.
PS.2.3. Light is a form of energy made of electromagnetic waves.
PS.2.3.a. Light waves travel in a straight line.
PS.2.3.b. Substances may cause light waves to change direction of travel (e.g., reflection, refraction).
PS.2.3.c. Sound is a form of energy caused by waves of vibrations that spread from its source.

OK.SPI. SCIENCE PROCESSES AND INQUIRY

SPI.1. Observe and Measure - Observing is the first action taken b 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 process standard.

SPI.1.1. Observe and measure objects, organisms, and/or events (e.g., mass, length, time, volume, temperature) using International System of Units (SI) (i.e., grams, milligrams, meters, millimeters, centimeters, kilometers, liters, milliliters, and degrees Celsius).

SPI.2. 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 process standard.

SPI.2.1. Classify a set of objects, organisms, and/or events using two or more observable properties (e.g., simple dichotomous keys).

SPI.3. 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 process standard.

SPI.3.3. Design and conduct a scientific investigation.
SPI.3.4. Recognize potential hazards and practice safety procedures in all science investigations.

SPI.4. 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 process standard.

SPI.4.1. Report data using tables, line, bar, trend, and/or simple circle graphs.
SPI.4.2. Interpret data tables, line, bar, trend and/or simple circle graphs.
SPI.4.3. Make predictions based on patterns in experimental data.
SPI.4.4. Communicate the results of investigations and/or give explanations based on data.

SPI.5. 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 process standard.

SPI.5.1. Use different ways to investigate questions and evaluate the fairness of the test.
SPI.5.2. Use a variety of measurement tools and technology.
SPI.5.3. Formulate a general statement to represent the data.
