This slide show delves into the various molecular shapes that fat can take, from fat the class of lipid macromolecules, to fat the cell type, to fat the tissue type.
Type of Material:
Presentation
Recommended Uses:
In class during lecture, in an online learning module, or as homework prior to a flipped classroom, even as a peer-to-peer teaching opportunity where students are given the slideshow and instructed to teach each other the material in small groups.
Technical Requirements:
Browser
Identify Major Learning Goals:
To recognize the structural characteristics of different types of fats, including fat molecules, fat cells, and fat tissues. To distinguish between cis- and trans- fats. To distinguish between saturated, monounsaturated, and polyunsaturated fatty acids. To understand health impacts of dietary trans fats, omega-3 fats, and cholesterol at a basic level.
Target Student Population:
middle school, high school, college gen ed, college lower division
Prerequisite Knowledge or Skills:
Basic knowledge of chemistry diagrams and biology are useful.
Content Quality
Rating:
Strengths:
The information is accurate
The illustrations are clear
Two types molecular model is shown, sometimes side by side
Concerns:
Lipid or fat is not really defined clearly
Other types of lipid are only touched on briefly (e.g., the range of steroids is not covered)
The ester linkage of fatty acids to glycerol is not mentioned at all
Little attention paid to glycerol within the triglyceride molecule
Potential Effectiveness as a Teaching Tool
Rating:
Strengths:
This presentation covers the aspects of fats normally covered in a non-majors lower division class, so this presentation would be of great value to instructors
The explanations and illustrations are clear, straightforward and easy understand, even for someone with little background
Concerns:
The space filling models might not be familiar to some users
The diagrams are not explained and are probably too advanced for some users
Learning objectives and prerequisite knowledge is not specifically addressed.
Ease of Use for Both Students and Faculty
Rating:
Strengths:
The slide loaded cleanly and all links worked as intended
The navigation was clear
Navigating backwards was especially fast
Concerns:
There is no table of contents
The slides must be viewed sequentially--there is no way to jump ahead or back
No narration means not accessible for visually-impaired students, who could only use this material if an instructor is providing audible narration
