Scientific MethodsVideo and Animations! New!
Check out these video animations to help you learn some key biology concepts! More on the way!
How to Catch a Criminal with DNA and Gel Electrophoresis!
This short video explains how gel electrophoresis can be used in forensic cases to determine if a suspect was present at a crime scene. It also has a great analogy to help you remember how and why the banding patterns of DNA fingerprints occur!
Cell Membrane and Transport Video Series
This
series of videos explains the structure of the plasma membrane and how
materials are transported across it. Diffusion, facilitated
diffusion, active transport, endocytosis, and exocytosis are all included
and clearly explained. There is a
longer series with more detailed
explanations and analogies, as well as a
short video series with short and
sweet animations that get right to the point. Check them both out!
Cellular Respiration Video Series
This series of videos explains how aerobic cell respiration works. Also, you get to see sugar explode! Glycolysis, the link reaction, the Krebs cycle, and the electron transport chain are all covered and animated to help you understand the process of making ATP (cell energy) using food and oxygen! This series goes with the Respiration Interactive activity and I recommend starting with
this activity here!
Variables in Science: Independent, Dependent, and Controlled
This short video explains variables, including independent variables, dependent variables, and controlled variables, using a simple example of an experiment with vitamins and squid. It also explains the importance of controlled variables in experimental design and shows an example of what can go wrong that involves nacho cheese. Check it out!
What are Viruses?
A short video explaining viruses and some fascinating facts about them, including the vast number of viruses, their incredibly small size, and how they work!
Enzymes and How They Work: An Introduction
All
living things depend on enzymes to stay alive and healthy! A quick and
simple explanation of how enzymes work!
Mitosis and the Cell Cycle
This animation shows the cell cycle (interphase, mitosis, and cytokinesis), using easy to follow animations, clear explanations, and helpful analogies. Perfect for any student of Biology interested in learning how cells divide to reproduce!
