- Understand how to find unknowns in scientific equations.
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. Acarology: Definition & History
Ticks and mites are tiny creatures, but they can cause some big problems. In this lesson, learn about acarology, the scientific discipline that studies these important arachnids.
11. Phycology: Definition, Facts & History
Under just about every body of water, there exists a secret world teeming with life. Much of this is in the form of algae. Phycology is the study of this algae, and in this lesson, you will learn all about it!
12. Ethnopharmacology: Definition & Examples
Ethnopharmacology studies natural medicines derived from plants and other substances that have been traditionally used by groups of people to treat various human diseases. In this lesson, learn more about this incredibly important science!
13. Evolutionary Physiology: Defintion & Examples
It is said that form follows function. When thinking of the natural world we can see many examples of this. Different shaped beaks of birds cater to their diet, streamlined shape of aquatic animals allow for swimming. The evolution of their physiology has best equipped them to their lifestyles and environments.
14. Forensic Acarology: Definition & Terms
Forensic acarology is the study of the activity of mites on a dead body for the purpose of solving a crime. This lesson is about forensic acarology, its definition, and the relevant terms that are used with it.
15. What is Bryology? - Definition & Advances
Bryology is the study of ancient plants, like mosses, that grow in moist, humid environments. These plants are some of the oldest species on Earth, but we are still learning new things about them every day! In this lesson, learn more about the exciting science of bryology.
16. What is Phytosociology? - Definition & History
There are many different methods of classifying plants. In this lesson, we will learn what phytosociology is and how it classifies plants and explore some of the methods used.
17. Palynology: Definition, Branches & Applications
Palynology studies pollen and spores produced by plants. It has many interesting applications, from crime scene analysis to understanding the diets of ancient people. In this lesson, learn about all the amazing things that palynology can tell us!
18. What is Forensic Palynology? - Definition & Cases
Most of us don't think about pollen outside of allergy season. But it turns out pollen is more useful than you think. This lesson discusses how pollen analysis is used to investigate and solve crimes.
19. What is Paleobotany? - Definition & Importance
Paleobotany allows us to know about the types of plants that lived long ago. It helps us to know more about what life on Earth was like in the distant past. Learn more about this fascinating science in this lesson!
20. Chronobiology: Definition & Examples
Chronobiology studies how natural rhythms affect living organisms. It can help explain why birds migrate, why trees drop their leaves in the fall, and even why some medications should only be taken at night. Learn all about it in this lesson.
21. Chronobiology & Nutrition
Chronobiology is the natural cycles in biology, including those that our body goes through. They can be altered by many different aspects, and in this lesson, we will explore how nutrition can change our chronobiology.
