About This Chapter
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.
Students will review:
This chapter helps students review the concepts in an investigation and experimentation unit of a standard middle school physical science course. Topics covered include:
- Steps in the scientific method
- Experimental design methods
- Data evaluation techniques
- Variables and controls in experiments
- Scientific graphs and charts
- Construction of graphs from data
- Linear and nonlinear relationships in data
- Methods for finding unknown quantities
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
