Data and Analysis

Computing Systems

Algorithms and Programming

Develop programs with sequences and loops, to express ideas or address a problem.

Break down (decompose) the steps needed to solve a problem into a precise sequence of instructions.

Develop plans that describe a program’s sequence of events, goals, and expected outcomes.

Give attribution (credit) when using the ideas and creations of others while developing programs.

Describe basic hardware and software problems using accurate terminology.

Store, copy, search, retrieve, modify, and delete information using a computing device and define the information stored as data.

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

Identify safe and unsafe examples of online communications.

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

Earth's Place in the Universe

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

Earth's Systems

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 kinds 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.

Ecosystems: Interactions, Energy, and Dynamics

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.

Biological Evolution: Unity and Diversity

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

Matter and its Interactions

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 an 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.

Engineering Design

Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool.

Develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem.

Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs.
