1. Science Vocabulary & Concepts: Study Skills & Word Parts
Learning science presents a unique set of challenges for students. In this lesson, learn the tricks of the trade as we discuss scientific vocabulary and other science study skills.
2. Identifying & Interpreting Independent & Dependent Variables
Scientists answer questions by performing experiments that have an independent variable, a dependent variable and at least one control variable. By controlling, adjusting and measuring these variables, scientists find answers to their questions.
3. 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.
4. Sampling Techniques In Scientific Investigations
We can learn a lot by gathering information from a small subset of a larger group. By sampling this smaller group, scientists can save time and money while still gaining a good understanding of the population as a whole.
5. 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.
6. The Metric System: Units and Conversion
Just like you and your friend communicate using the same language, scientists all over the world need to use the same language when reporting the measurements they make. This language is called the metric system. In this lesson we will cover the metric units for length, mass, volume, density and temperature, and also discuss how to convert among them.
7. Unit Conversion and Dimensional Analysis
How is solving a chemistry problem like playing dominoes? Watch this lesson to find out how you can use your domino skills to solve almost any chemistry problem.
8. Significant Figures and Scientific Notation
Are 7.5 grams and 7.50 grams the same? How do scientists represent very large and very small quantities? Find out the answers to these questions in this video.
9. Understanding Textual & Non-Textual Scientific Presentations
In order to understand science, you have to know science. This knowledge includes understanding the various ways that scientific information may be presented as well as how to critically analyze that information.
10. 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.
11. Interpreting Graphs and Charts of Scientific Data: Practice Problems
Do charts and graphs make problem-solving difficult? Complex problems with visual representations can drain your brain during a test. In this lesson, learn three simple rules for solving problems with charts and graphs. We'll try them out as we walk through two sample problems.
12. Interpreting Tables of Scientific Data: Practice Problems
Complex table problems getting you down? Multi-question, situational problems don't have to be a drag on your testing performance. Learn how to apply three simple rules as we walk through two table problems together.
13. Design a Scientific Experiment: Example of Avery and Griffith's Experiment
What are the requirements of a scientific experiment? How do scientists design their investigations? In this lesson, we'll use the work of Avery and Griffith to explore the process of experimental design.
14. What is Physics? - Definition, Branches, Fundamentals & Topics
Get a basic overview of modern physics. Learn about the science's origins, the fields of physics being worked in today, and the major subject areas taught in general physics courses.
15. Molality: Definition & Formula
In chemistry, knowing the concentration of a solution is very important. There are different ways to express the amount of concentration, and one of these is by calculating the molality. In this lesson, we discuss molality.
16. Nanometers: Definition & Symbol
Discover what exactly is meant by the term nano. Then learn exactly how small nanometer sized objects are, and some examples of what exists at that size scale both naturally and artificially created.
17. Natural Laws of Science: Definition & Examples
Natural laws describe how many parts of the natural world work. This lesson defines natural laws and explains the difference between laws and theories. Several examples from physics, biology, and chemistry are also used to illustrate different laws within the natural sciences.
18. Phase Changes of Matter: Types & Examples
We are surrounded by matter. In this lesson, you will learn about phase changes of matter, and the types of phase changes that occur so you can recognize them in the future.
19. Primary Structure of Protein: Definition & Overview
The primary structure of a protein is what is encoded in the DNA. All other protein structures involve folding of the protein, chemical interactions within the protein, and protein-protein interactions. This lesson describes primary protein structure.
20. Principal Quantum Number: Definition & Example
Quantum numbers were developed to characterize electrons - its electron configuration, movement and position in an atom. Each electron has a unique set of quantum numbers. Of the four quantum numbers, our focus in this lesson is the principal quantum number.
21. Radial Symmetry in Biology: Definition & Examples
One way that animals are broadly categorized is based on their body symmetry. Radial symmetry is one type, and here we will explore what it is and what organisms exhibit it. At the end, you can test your knowledge with a brief quiz.
22. Reactant in Chemistry: Definition & Examples
This lesson defines reactants within chemical reactions and how reactants are written in chemical reactions. The role of chemical reactions in reactions is explained, and several examples are provided to provide important context.
23. Reduction in Chemistry: Definition & Overview
When atoms are greedy for electrons, they steal them from other atoms. This reduces their charge. You can see the effects of reduction in the world around you. Learn more about reduction in chemistry and see some examples of it.
24. Selective Permeability: Definition & Overview
This lesson will provide you with a definition of selective permeability. Also, an example and illustration will be provided to support your understanding of the process.
25. Significant Figure: Definition, Examples & Practice Problems
In this lesson, you'll learn about the concept of significant figures and apply it to addition, subtraction, multiplication, and division. You'll learn what numbers are significant, why they are significant, and how to deal with zeroes in a number.
26. Solubility in Chemistry: Definition & Properties
This lesson defines solubility and discusses this property in the context of chemistry. The lesson also includes a discussion of the impact that temperature and intermolecular interactions can have on solubility.
27. Strong Acid: Definition & Examples
Acids are very common in nature and in chemical reactions. In this lesson, you will learn what makes a substance an acid and how to recognize strong acids from others.
28. Strong Base: Definition & Examples
Next time you open your medicine cupboard or pick up some cleaning supplies, beware you might be handling some strong bases! In this lesson, learn the definition of a strong base and where you can find them, then test your new knowledge with a quiz.
29. Spontaneous Generation: Definition, Theory & Examples
Did you know that people (scientists included) thought that mice came from wheat and old shirts? Learn about theory of spontaneous generation and the centuries-long debate over its validity.
