4.1  Unifying Concepts and Processes

Unifying concepts and processes help students think about and integrate a range of basic ideas which builds an understanding of the natural world.

• Describe the parts that make up a system.
• Relate how the parts of a system affect the whole system.

• System is a group of related objects that work together for a particular purpose (machines, organism).
• Most things are made of parts
• When parts are put together, they can do things that they couldn’t do by themselves.
• Often a person can find out about a group of things by studying one or a few of them.
• A group of objects may be sub classified in one or more ways.
• The parts in a system interact with the other parts to cause the system to work
• A system may not work if a part is missing, broken, worn out, mismatched, or misconnected.
• A small part of something may be special in some way, yet not give an accurate picture of the whole.

• Sort objects by their characteristics.

• Objects can be ordered by their properties
• Objects can be classified as either natural or of human design

• Organization of objects, organisms, events, and systems help people understand similarities and differences that in turn help understand the world.
• Objects have more than one property
• Objects are classified by their properties.
• Objects in a group may share some characteristics and differ in others.
• Objects are identified and described by their properties.
• Objects, organisms, events, and systems can be organized into groups with similar properties.

Evidence consists of observations and data on which to base scientific explanations.

The goal is to help students use evidence to understand interactions and predict changes

• Use evidence gathered from an investigation to develop a scientific explanation.

• Evidence is something that is observed and can be used to understand what is happening and make predictions about future changes in natural and designed systems.
• Observation helps us learn.
• Observation helps understand interactions and predict changes.
• We can use one or more of the five senses to observe and describe objects.
• Practice helps us to be better observers.
• Predictions are guesses based on what people know.
• If people didn't have previous experiences, then there prediction is a "wild guess".
• Pictures can be used to represent features of objects being described.
• Recording observations helps remember specific information.
• Observations are used to help make explanations.
• When people disagree on observational data, they usually make more observations to increase the reliability of their observations.
• Observation, creativity, and logical argument are used to explain how things work.
• The more experience or data a person has the better prediction they are likely to make
• The way a system works can be used to describe and explain what it is (operational definition).
• Events can be classified as probable, improbable, possible, or impossible.
• Records need to be kept during investigations and not created or altered later.

Models are tentative schemes or structures that correspond to real objects, events, or classes of events, and that have explanatory power.

The goal is to help students learn how to make and use many models, including physical objects, plans, mental constructs, mathematical equations, and computer simulations.

• Create a model, graph, or illustration that represents an object, living thing, or an.
• Explain and answer questions about a model and how it represents an object, living thing, or an event.
• Explain procedures or ideas in more than one way (e.g., sketches, charts, and graphs).

• Pictures and drawings can be used to represent features of objects being described.
• Sketches can be usd to explain procedures and/or ideas.
• An object’s motion can be described by tracing and measuring its position over time.
• Models are structures that are similar to real objects in some ways.
• Models may be missing detail, different size, or not able to do all of the same things.
• A model though different from the real thing can be used to learn something about the real thing.
• Seeing how a model changes may suggest how the real thing works if the same were done to it.
• Geometric figures, number sequences graphs, diagrams, sketches, number lines, maps, and stories can be used to represent objects, events, and processes in the real world. Such representations can never be exact in every detail.
• Create a model, graph, or illustration that represents an object, living thing, or an event.
• Explain and answer questions about a model and how it represents an object, living thing, or an event.
• Models are structures that correspond to real objects, events, or classes of events.
• Data can be organized by time: before, during, and after an event/interaction.

Explanations provide interpretation, meaning, or sense to objects, organisms, or events. Explanations incorporate existing scientific knowledge and new evidence from observations, experiments, or models into internally consistent, logical statements, such as hypotheses, laws, principles, and theories.

The goal is to help students create explanations which incorporate a scientific knowledge base, logic, and higher levels of analysis.

• Explanations are based on observation derived from experience or experimentation and are understandable.
• Good explanations are based on evidence from systematic scientific investigations.
• Scientists raise questions about the world around them and seek answers to some of them by combining observation and trying things out.

• Objects can be compared to other objects.
• Explanations tell how something does what it does
• People are more likely to believe your ideas if you give good reasons for them.
• One way to understand something is to think how it is like something else.
• One way to describe something is to say how it is like something else.
• Strong feelings can affect a person's reasoning.
• How do I know is a good question to ask to try and understand what is or has happened.
• Sometimes people aren’t sure what will happen because they don’t know everything that might be having an effect on the event.
• Some events are more likely to happen than others.
• Some events can be predicted more accurately than others.
• To create a better communicate an explanation, procedures or ideas it is helpful to include a variety of media (written words, oral explanations, sketches, charts, graphs, ...).
• Reasonable conclusions can be made when a rule that always holds is related to good information about a particular situation. If then logic. (If plants are green and this is green, then it is a plant. If John is not a plant and he paints himself green he will not be a plant.)
• Reasoning by similarities can suggest ideas but can't prove them.
• Practical reasoning may require several steps.
• Often a person can find out about a group of things by studying just a few of them.
• When people disagree on explanations for an observation they usually make more observations to refine their explanations.
