Stability and Change - Things may change slowly or rapidly.

Stability and Change - Things may change slowly or rapidly.

Patterns - Patterns in the natural world can be observed.

Patterns - Patterns in the natural world can be observed.

Cause and Effect - Events have causes that generate observable patterns.

Structure and Function - The shape and stability of structures of natural and designed objects are related to their function(s).

Patterns - Patterns in the natural world can be observed.

Patterns - Patterns in the natural and human-designed world can be observed.

Cause and Effect - Simple tests can be designed to gather evidence to support or refute student ideas about causes.

Energy and Matter - Objects may break into smaller pieces and be put together into larger pieces, or they may change shape.

Cause and Effect - Events have causes that generate observable patterns.

The History of Planet Earth - Some events happen very quickly; others occur very slowly, over a time period much longer than one can observe.

Earth Materials and Systems - Wind and water can change the shape of the land.

Plate Tectonics and Large-Scale System Interactions - Maps show where things are located. One can map the shapes and kinds of land and water in any area.

The Roles of Water in Earth's Surface Processes - Water is found in oceans, rivers, lakes, and ponds. Water exists as solid ice and in liquid form.

Developing Possible Solutions - Designs can be conveyed through sketches, drawings, or physical models. These representations are useful in communicating ideas for a problem's solutions to other people.

Optimizing the Design Solution - Because there is always more than one possible solution to a problem, it is useful to compare and test designs.

Interdependent Relationships in Ecosystems - Plants depend on water and light to grow.

Interdependent Relationships in Ecosystems - Plants depend on animals for pollination or to move their seeds around.

Biodiversity and Humans - There are many different kinds of living things in any area, and they exist in different places on land and in water.

Structure and Properties of Matter - Different kinds of matter exist and many of them can be either solid or liquid, depending on temperature. Matter can be described and classified by its observable properties.

Structure and Properties of Matter - Different properties are suited to different purposes.

Structure and Properties of Matter - Different properties are suited to different purposes. A great variety of objects can be built up from a small set of pieces.

Chemical Reactions - Heating or cooling a substance may cause changes that can be observed. Sometimes these changes are reversible, and sometimes they are not.

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 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.

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 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.

Constructing Explanations and Designing Solutions - Make observations from several sources to construct an evidence-based account for natural phenomena.

Developing and Using Models - Develop a model to represent patterns in the natural world.

Constructing Explanations and Designing Solutions - Compare multiple solutions to a problem.

Obtaining, Evaluating, and Communicating Information - Obtain information using various texts, text features (e.g., headings, tables of contents, glossaries, electronic menus, icons), and other media that will be useful in answering a scientific question.

Planning and Carrying Out Investigations - Plan and conduct an investigation collaboratively in order to produce data to serve as the basis for evidence to answer a question.

Developing and Using Models - Develop a simple model based on evidence to represent a proposed object or tool.

Planning and Carrying Out Investigations - Make observations (firsthand or from media) to collect data that can be used to make comparisons.

Planning and Carrying Out Investigations - Plan and conduct an investigation collaboratively in order to produce data to serve as the basis for evidence to answer a question.

Analyzing and Interpreting Data - Analyze data from tests of an object or tool to determine if it works as intended.

Constructing Explanations and Designing Solutions - Make observations (firsthand or from media) to construct an evidence-based account for natural phenomena.

Engaging in Argument from Evidence - Construct an argument with evidence to support a claim.

Ask questions, make observations, and gather information about a situation that 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.

Structure and Function - The shape and stability of structures of natural and designed objects are related to their function(s).

Optimizing the Design Solution - Because there is always more than one possible solution to a problem, it is useful to compare and test designs.

Defining and Delimiting Engineering Problems - A situation that people want to change or create can be approached as a problem to be solved through engineering. Asking questions, making observations, and gathering information are helpful in thinking about problems. Before beginning to design a solution, it is important to clearly understand the problem.

Developing Possible Solutions - Designs can be conveyed through sketches, drawings, or physical models. These representations are useful in communicating ideas for a problem's solutions to other people.

Asking Questions and Defining Problems - Ask questions based on observations to find more information about the natural and/or designed world(s). Define a simple problem that can be solved through the development of a new or improved object or tool.

Developing and Using Models - Develop a simple model based on evidence to represent a proposed object or tool.

Analyzing and Interpreting Data - Analyze data from tests of an object or tool to determine if it works as intended.
