Biology: Biology Basics: 01: Scientific Method - Medical Animation
MEDICAL ANIMATION TRANSCRIPT: We'll begin our study of biology with the scientific method. The word biology is made up of the terms bio, which means life, and the suffix, ology, which means the study of. So, biology is the study of life and living organisms. And the foundation of all sciences, including biology, is the scientific method. The scientific method is an orderly way of investigating and evaluating factual information to learn how the world around us works. The basic steps of the scientific method are:making an observation, forming an inference and developing a hypothesis, conducting a controlled experiment, and drawing conclusions. Scientists use their senses to notice things in the world around them. After making observations, scientists ask questions, and then gather information, called data. After making observations, scientists ask questions, and then gather information, called data. For example, My car is terrible! is an example of subjective data. In contrast, My car wont start! is objective data, and is an example of an observation. Lets use this car trouble as an everyday example of using the scientific method to solve a problem. In this situation, when youre having trouble with your car, you might then ask, Why wont my car start? Well, there could be a number of causes maybe the car is out of fuel, or the battery might be dead. You could use an inference to possibly eliminate one of these things. Using an inference means to apply information in a logical way to reach a conclusion. In this example, your inference might be that the problem isnt a lack of fuel, because you know you filled the gas tank yesterday and havent driven the car very far since then. Your inference that a lack of fuel isnt the cause of the car failing to start may lead you to think the problem might be a dead battery. You can use this idea to form a testable explanation, called a hypothesis. You must to be able to test a hypothesis in order for it to be considered valid and scientific! A hypothesis can be presented in the form of an if then statement. In this case, the hypothesis might be, If my car starts when I use jumper cables, then the battery is the problem. This hypothesis is testable because either your car will or wont start when you use the jumper cables. Now, you can design a controlled experiment to test your hypothesis. During a controlled experiment, you control, or keep constant, all the factors, known as variables, except for the one you want to test. In this experiment, the variable that changes is the battery, while all other possible variables that might prevent the car from starting are not manipulated or changed. Why must you change only one variable? Because if you change or affect more than one, you wont know which variable caused the car to start. You can carry out your controlled experiment by attaching jumper cables from a charged battery to the battery in your car to see if the car then starts. In an actual experiment, you would record any data that results, such as how long you tried to jump-start the battery, and whether or not the car started. Well cover more details on controlled experiments and types of data in separate videos. After completing your experiment, you can draw a conclusion by using the resulting data to see if it supports your hypothesis. Remember, your hypothesis was, If my car starts when I use jumper cables, then the battery is the problem. The results of the experiment confirmed the hypothesis, so the conclusion is that the battery was the problem. If your car didnt start when using jumper cables, then your original hypothesis was not supported. As a result, a new hypothesis needs to be formed and tested. The scientific method continues until no more options remain. In review, the basic steps of the scientific method are: making an observation, forming an inference and developing a hypothesis, conducting a controlled experiment, and drawing conclusions.

What attorneys say about MLA and The Doe Report:
"There is nothing like a great graphic depicting the real nature and extent of a victim's injuries to get full value for your client. I use Medical Legal Art for mediations as well as trial."

"Whether it's demonstrating a rotator cuff tear, neck movement a few milliseconds after rear impact, or a proposed lumbar fusion, the Doe Report represents an instant on-line database of medical illustration for health-care and legal professionals.

Illustrations can be purchased 'as is' or modified within hours and sent either electronically or mounted on posterboard. An illustration is worth a thousand words, as juries perk up and look intently to capture concepts that are otherwise too abstract. Start with good illustrations, a clear and direct voice, a view of the jury as 12 medical students on day one of training, and your expert testimony becomes a pleasure, even on cross examination. An experienced trial lawyer should also emphasize these illustrations at the end of trial, as a means of visually reinforcing key concepts covered.

As a treating physician, I also use these accurate illustrations to educate my own patients about their medical conditions. The Doe Report is an invaluable resource, and its authors at MLA have always been a pleasure to work with."

"For us, the defining feature of effective demonstrative evidence is whether, by itself, the piece will tell the story of the case. Medical legal Art provides our firm with illustrations and animations that are clear and persuasive. Their exhibits tell the story in a way that allows the jury to understand a very complex subject, very quickly."

"Thanks, and your illustrations were effective in a $3 million dollar verdict last Friday."
