Ecosystems: Interactions, Energy and Dynamics

Matter and Its Interactions

Use information from several sources to provide evidence that Earth events can occur quickly or slowly.

Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land.

Develop a model to represent the shapes and kind of land and bodies of water in an area.

Obtain information to identify where water is found on Earth and that it can be solid or liquid.

Plan and conduct an investigation to determine if plants need sunlight and water to grow.

Develop a simple model that mimics the function of an animal in dispersing seeds or pollinating plants.

Make observations of plants and animals to compare the diversity of life in different habitats.

Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.

Analyze data obtained from testing different materials to determine which materials have the properties that are best suited for the intended purpose.

Make observations to construct an evidence-based account of how an object made of a small set of pieces can be disassembled and made into a new object.

Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot.

Algorithms and Programming

With guidance, model daily processes by creating and following algorithms (sets of step by step instructions) to complete tasks verbally, kinesthetically, with robot devices, or a programming language.

Algorithms

With guidance, independently and collaboratively create programs to accomplish tasks using a programming language, robot device, or unplugged activity that includes sequencing and repetition.

Control

With guidance, decompose (break down) the steps needed to solve a problem into a precise sequence of instructions.

Modularity

Independently or with guidance, create a grade-level appropriate artifact to illustrate thoughts, ideas, or stories in a sequential manner (e.g., story map, storyboard, and sequential graphic organizer).

Give credit to ideas, creations and solutions of others while writing and developing programs.

With guidance, independently and collaboratively debug programs using a programming language and/or unplugged activity that includes sequencing and repetition.

Use correct terminology (e.g., debug, program input/output, code) to explain the development of an algorithm to solve a problem in an unplugged activity, hands on manipulatives, or a programming language.

Program Development

Variables

Model the way a computer program stores, accesses, and manipulates data that is represented as a variable.

Computing Systems

Devices

Select and use appropriate computing devices or software to perform a variety of tasks for an intended outcome.

Hardware & Software

Identify the components of a computing system and what the basic functions are (e.g., hard drive and memory) as well as peripherals (e.g., printers, scanners, external hard drives) and external storage features and their uses (e.g., cloud storage).

Troubleshooting

Identify, using accurate terminology, simple hardware and software problems that may occur during use (e.g., program is not working as expected, no sound is coming from the device, caps lock turned on) and discuss problems with peers and adults.

Data Analysis

Collection, Visualization, & Transformation

With guidance, collect and present the same data in various visual formats.

Inference & Models

With guidance, construct and interpret data with up to four categories and present it in a chart, bar graph, or pictograph (visualization) in order to draw conclusions with or without a computing device.

Storage

With guidance, develop and modify an organizational structure by creating, copying, moving, and deleting files and folders.

Impacts of Computing

Compare how people live and work before and after the implementation or adoption of new technology.

Culture

Social Interactions

With guidance, develop a code of conduct, explain, and practice grade-level appropriate behavior and responsibilities while participating in an online community. Identify and report inappropriate behavior.

Internet Safety, Law, & Ethics

Individually and collaboratively identify ways to stay safe online.

Networks & The Internet

Cybersecurity

Explain what passwords are, why we use them, and use strong passwords to protect computing devices and information from unauthorized access.

Network Communication & Organization

Recognize that computing devices can be connected in a variety of ways.
