Ch 8: PSSA - Science Grade 8: Systems, Models & Patterns

About This Chapter

Have your students go through this chapter to bring back their memories about systems, models, and patterns. Encourage students to review each lesson to brush up on the major terms and concepts that will be covered on the PSSA - Science Grade 8 test.

PSSA - Science Grade 8: Systems, Models & Patterns - Chapter Summary

To give your students the best chance at passing the PSSA - Science Grade 8 test, have your students go through this extensive study guide about systems, models, and patterns. Within the lessons, our instructors address systems theory, the different types of technological systems, scientific uses for simulations and models, and the importance of patterns. Other topics addressed in this chapter are as follows:

  • Examples of systems analysis
  • Outputs and inputs used by systems
  • An explanation of open and closed systems
  • The process of engineering design
  • The relationship between cause and effect

If you have a competitive student, you can motivate them to use our study materials by challenging them to take our lesson quizzes. There is a lesson quiz connected to every lesson we offer. Your student can take the quiz before or after reviewing the lesson. All of the questions are multiple-choice, and they cover the most pertinent topics, such as definitions, critical thinking, and reading comprehension. As your student prepares for the PSSA - Science Grade 8 test, answering the questions on our quizzes will give your student a baseline of how well he or she knows this particular topic.

Systems Analysis: Definition & Example

1. Systems Analysis: Definition & Example

What is systems analysis? And how is it used to solve problems? Learn about systems analysis and some examples. See how well you analyzed the information in this lesson by taking a quiz.

How Systems Use Inputs & Outputs

2. How Systems Use Inputs & Outputs

Systems are all around us. But what are they and how do they work? Learn about inputs and outputs, then see how this lesson's input affected your mental systems by taking a quiz.

Closed & Open Systems: Definition & Examples

3. Closed & Open Systems: Definition & Examples

In this lesson, you'll learn the difference between closed and open physical systems. Explore examples of when each kind of system occurs, and learn why scientists sometimes choose one over the other.

Why Scientists Use Models & Simulations

4. Why Scientists Use Models & Simulations

What is a model? What is a simulation? And why do scientists use them? Learn how scientists analyze the past and predict the future. Then take a quiz to test your new knowledge.

Engineering Design: Definition & Process

5. Engineering Design: Definition & Process

In this lesson, we will define engineering design and explain the engineering design process from defining the problem to testing and redesigning the final product.

Cause and Effect Relationship: Definition & Examples

6. Cause and Effect Relationship: Definition & Examples

This lesson explores the relationship between cause and effect and teaches you about the criteria for establishing a causal relationship, the difference between correlation and causation, and more.

Patterns in Nature: Definition & Examples

7. Patterns in Nature: Definition & Examples

Look carefully at the world around you and you might start to notice that nature is filled with many different types of patterns. In this lesson we will discuss some of the more common ones we come across.
