Grade 8 Science Oklahoma standards Standards

Students will continue to apply the standards and practices from the previous grade levels.

Algorithms & Programming

Algorithms

Design algorithms in natural language, flow and control diagrams, comments within code, and/or pseudocode to solve complex problems.

Control

Develop programs that utilize combinations of nested loops, compound conditionals, procedures without parameters, and the manipulation of variables representing different data types.

Modularity

Decompose problems and subproblems into parts to facilitate the design, implementation, and review of complex programs.

Program Development

Seek and incorporate feedback from team members and users to refine a solution to a problem that meets the needs of different users.

Incorporate existing code, media, and libraries into original programs of increasing complexity and give attribution.

Systematically test and refine programs using a range of student created inputs.

Model effective communication between participants and demonstrate successful collaboration when developing computational artifacts.

Document text-based programs of increasing complexity in order to make them easier to follow, test, and debug.

Variables

Computing Systems

Devices

Develop and implement a process to evaluate existing computing devices and recommend improvements to the design based on how other users interact with the device.

Hardware & Software

Design and refine projects that combine hardware and software components to collect and exchange data.

Troubleshooting

Systematically identify, resolve, and document complex software and hardware problems with computing devices and their components.

Data Analysis

Collection, Visualization, & Transformation

Develop, implement, and refine a process that utilizes computational tools to collect and transform data to make it more useful and reliable.

Inference & Models

Refine computational models based on the data generated by the models.

Storage

Impacts of Computing

Culture

Explore careers related to the field of computer science, and explain how computing impacts innovation in various career fields.

Evaluate and improve the design of existing technologies to meet the needs of different users and increase accessibility and usability.

Social Interactions

Describe and use safe, appropriate, and responsible practices (i.e., netiquette) when participating in online communities and understand the impact of not using safe, appropriate, and responsible practices.

Communicate and publish key ideas and details individually or collaboratively in a way that informs, persuades, and/or entertains using a variety of digital tools and media-rich resources.

Internet Safety, Law, & Ethics

Discuss the social impacts and ethical considerations associated with cybersecurity, including the positive and malicious purposes of hacking.

Networks & The Internet

Cybersecurity

Evaluate physical and digital procedures that could be implemented to protect electronic data/information; explain the impacts of cybersecurity threats and attacks.

Compare the advantages and disadvantages of methods of encryption to model the secure transmission of information.

Network Communication & Organization

Explain protocols and their importance to data transmission; model how packets are broken down into smaller pieces and how they are delivered.

Earth's Place in the Universe

Biological Unity and Diversity

Heredity: Inheritance and Variation of Traits

From Molecules to Organisms: Structure and Processes

Waves and Their Applications in Technologies for Information Transfer

Motion and Stability: Forces and Interactions

Develop and use a model of the Earth-sun-moon system to describe the cyclic patterns of lunar phases, eclipses of the sun and moon, and seasons.

Develop and use a model to describe the role of gravity in the motions within galaxies and the solar system.

Analyze and interpret data to determine scale properties of objects in the solar system.

Use arguments based on empirical evidence and scientific reasoning to support an explanation for how characteristic animal behaviors and specialized plant structures affect the probability of successful reproduction of animals and plants respectively.

Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms.

Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism.

Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation.

Analyze and interpret data to identify patterns within the fossil record that document the existence, diversity, extinction, and change of life forms throughout the history of life on Earth.

Apply scientific ideas to construct an explanation for the patterns of anatomical similarities and differences among modern organisms and between modern and fossil organisms to infer ancestral relationships.

Analyze displays of pictorial data to compare patterns of similarities in the embryological development across multiple species to identify relationships not evident in the fully formed anatomy.

Construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals' probability of surviving and reproducing in a specific environment.

Gather and synthesize information about the practices that have changed the way humans influence the inheritance of desired traits in organisms.

Use mathematical representations to support explanations of how natural selection may lead to increases and decreases of specific traits in populations over time.

Apply Newton's Third Law to design a solution to a problem involving the motion of two colliding objects in a system.

Plan an investigation to provide evidence that the change in an object's motion depends on the sum of the forces on the object and the mass of the object.

Ask questions about data to determine the factors that affect the strength of electric and magnetic forces.

Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.

Conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact.

Use mathematical representations to describe patterns in a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.

Integrate qualitative scientific and technical information to support the claim that digitized signals (sent as wave pulses) are a more reliable way to encode and transmit information.
