Data and Analysis

Computing Systems

Algorithms and Programming

Test, compare, and refine multiple algorithms for the same task and determine which is the most appropriate.

Develop programs that include sequences, events, loops, and conditionals.

Explore how complex tasks can be decomposed into simple tasks and how simple tasks can be composed into complex tasks.

Test and debug (identify and fix) errors in a program or algorithm to ensure it runs as intended.

Model how computer hardware and software work together as a system to accomplish tasks.

Use data to highlight or propose cause-and-effect relationships, predict outcomes, or communicate ideas.

Compare and contrast how computing has changed society from the past to the present.

Model how information is broken down into smaller pieces, transmitted as packets through multiple devices over networks and the internet, and reassembled at the destination.

Engineering Design

Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.

Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.

Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.

Earth's Place in the Universe

Identify evidence from patterns in rock formations and fossils in rock layers to support an explanation for changes in a landscape over time.

Earth's Systems

Make observations and/or measurements to provide evidence of the effects of weathering or the rate of erosion by water, ice, wind, or vegetation.

Analyze and interpret data from maps to describe patterns of Earth's features.

Earth and Human Activity

Obtain and combine information to describe that energy and fuels are derived from natural resources and their uses affect the environment.

Generate and compare multiple solutions to reduce the impacts of natural Earth processes on humans.

From Molecules to Organisms: Structures and Processes

Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction.

Use a model to describe that animals' receive different types of information through their senses, process the information in their brain, and respond to the information in different ways.

Energy

Use evidence to construct an explanation relating the speed of an object to the energy of that object.

Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.

Ask questions and predict outcomes about the changes in energy that occur when objects collide.

Apply scientific ideas to design, test, and refine a device that converts energy from one form to another.

Waves and their Applications in Technologies for Information Transfer

Develop a model of waves to describe patterns in terms of amplitude and wavelength and that waves can cause objects to move.

Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen.

Generate and compare multiple solutions that use patterns to transfer information.
