This is a two to three minute You Tube animation reviewing the concept of microbial quorum sensing. The animation is narrated and is highlighted by the appearance of key terms during various steps of the process depicted.
Explain what quorum sensing is
Explain how gram + and gram – preform this sensing
Explain the type of signaling and what the bacteria do in response to the signal
Target Student Population:
Students who would benefit from this animation include AP Biology or Chemistry students at the high school level and General Biology, General Chemistry or General Microbiology students at the college level.
Prerequisite Knowledge or Skills:
A basic understanding of cell structure and what is meant by gram + or gram - is required to fully understand this animation.
Type of Material:
This is a stand alone animation with voice-over functionality.
This animation would be useful as an introduction to the topic of quorum sensing. It is very short and provides a basic background of a very complex topic. Instructors can then decide how much detail they wish to expand to once the animation is viewed.
Evaluation and Observation
Great animation; simple explanation
Explains the communication of bacteria very well
Shows how the protein provides intra cellular signaling to DNA
Briefly explains G-proteins
Probably should view after the genetics chapter
Potential Effectiveness as a Teaching Tool
The simplicity of this animation makes it very useful for the introduction of this topic in a course
Could be used in class or as an out of class assignment or review
Content level makes it inappropriate for advanced students
Addition of a quiz would enhance the animation
Ease of Use for Both Students and Faculty
Easy to navigate
Simple to use
Not ADA compliant-- there need to be subtitles for the voice over narration
Other Issues and Comments:
Good video. Great concept to take something this difficult to understand and make it easy.
