Ch 9: Investigation & Experimentation in Physical Science: Help and Review

About This Chapter

The Investigation and Experimentation in Physical Science chapter of this Middle School Physical Science Help and Review course is the simplest way to master digging deeper into physical science. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of investigation and experimentation in physical science.

Who's it for?

Anyone who needs help learning or mastering middle school physical science material will benefit from taking this course. There is no faster or easier way to learn middle school physical science. Among those who would benefit are:

  • Students who have fallen behind in understanding experimentation and investigation methods
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about investigation and experimentation in physical science
  • Students who struggle to understand their teachers
  • Students who attend schools without extra science learning resources

How it works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the Investigation and Experimentation in Physical Science chapter exam.

Why it works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the Investigation and Experimentation in Physical Science chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any question about investigation and experimentation in physical science. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

The Scientific Method: Steps, Terms & Examples

1. The Scientific Method: Steps, Terms & Examples

The scientific method is more than just hypotheses and experiments. In this lesson, we'll explore the themes and variations that make up the world of science.

Experimental Design in Science: Definition & Method

2. Experimental Design in Science: Definition & Method

What are the requirements of a scientific experiment? How do scientists turn hypotheses into theories and laws? Learn the answers to these questions and more in this lesson on the design of scientific experiments.

Evaluating Data from Scientific Investigation

3. Evaluating Data from Scientific Investigation

After watching this video, you will be able to explain the meaning of the terms 'accuracy' and 'reproducibility,' or precision, as they relate to science experiments. A short quiz will follow.

Variables & Controls in a Science Experiment

4. Variables & Controls in a Science Experiment

After watching this video, you will be able to explain how science experiments are conducted; what variables, controlled variables, and controls are: and why these things are important. A short quiz will follow.

Measures of Central Tendency: Definitions & Practice

5. Measures of Central Tendency: Definitions & Practice

After watching this video, you will be able to explain the meaning of the terms central tendency, mode, mean and median. You will also be able to calculate these three values from provided data. A short quiz will follow.

How to Read Scientific Graphs & Charts

6. How to Read Scientific Graphs & Charts

How do scientists summarize their findings with visual aids? In this lesson, explore the different types of tables, charts and graphs that scientists use. Learn to read these effectively as a preview to your science studies.

How to Construct Graphs from Data & Interpret Them

7. How to Construct Graphs from Data & Interpret Them

After watching this video, you should be able to explain what a graph is, construct a scatter plot, and interpret scatter plots from scientific data. A short quiz will follow.

Linear & Nonlinear Relationships in Data Graphs

8. Linear & Nonlinear Relationships in Data Graphs

After watching this video, you will be able to explain the difference between linear and nonlinear relationships when plotting graphs. A short quiz will follow.

Solve for Unknowns in Scientific Equations

9. Solve for Unknowns in Scientific Equations

Calculating a missing value in an equation is something you may come across in your scientific analyses. As long as you know the relationship between the variables in the equation, as well as the rest of the measured values, this is a relatively straightforward process for you to master.

Two Main Branches of Physical Science

10. Two Main Branches of Physical Science

In this lesson, we will discuss how physics and chemistry are considered to be the two main branches of physical science. We will also look at the overlap between physics and chemistry.

How to Build a Spaghetti Bridge: Instructions, Ideas & Tips

11. How to Build a Spaghetti Bridge: Instructions, Ideas & Tips

Hands-on learning is always the most exciting for students and teachers. In this lesson, you'll learn how to teach students about force through building spaghetti bridges, a much-loved engineering project for physics students.

Triple Beam Balance: Definition & Use

12. Triple Beam Balance: Definition & Use

A triple beam balance is a really useful piece of laboratory equipment that you can use to find the mass of an object. In this lesson, learn what a triple beam balance looks like and how to use it.
