About This Chapter
Who's it for?
This unit of our Middle School Physical Science Homeschool course will benefit any student who is trying to learn how to carry out science investigations and experiments. There is no faster or easier way to learn about investigation and experimentation in physical science. Among those who would benefit are:
- Students who require an efficient, self-paced course of study to learn about the scientific method, experimental design, linear and non-linear relationships, how to determine an unknown quantity and how to read graphs and charts.
- Homeschool parents looking to spend less time preparing lessons and more time teaching.
- Homeschool parents who need a science curriculum that appeals to multiple learning types (visual or auditory).
- Gifted students and students with learning differences.
How it works:
- Students watch a short, fun video lesson that covers a specific unit topic.
- Students and parents can refer to the video transcripts to reinforce learning.
- Short quizzes and a physical science investigation and experimentation unit exam confirm understanding or identify any topics that require review.
Investigation and Experimentation in Physical Science Unit Objectives:
- List and describe the steps in the scientific method.
- Define experimental design in science, and explain how it's carried out.
- Discuss evaluating data from scientific investigations.
- Discuss the difference between variables and controls.
- Describe how to read scientific charts and graphs.
- Demonstrate how to build a graph from data, and describe the relationship among variables.
- Explain the difference between linear and non-linear relationships as plotted on a graph.
- Demonstrate how to apply mathematical formulas to find an unknown quantity.
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.
