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. What is a Responding Variable? - Definition & Example
In this lesson, you will learn what a responding variable is, and how it relates to the other variables in an experiment. You will also read an example of a simple experiment, and try to determine what the responding variable is.
