Accessibility Statement: Portion Distortion Trends Over Time

Portion Distortion Trends

Accessibility for educational games is a work in progress across the industry. We continually seek solutions to make our products fully accessible, and we strive to adhere to established standards for accessibility and usability on each new project. Some of our older products may not be accessible in all areas and have not been optimized for current accessibility recommendations. Here, we offer the content and approach of this game, so that learners are better able to find alternative content and ways of learning.

Content of modules:

Portion Distortion lets users explore how the serving size of various foods has changed in the US from 1977 to 1996. By clicking on a time period (either 1977-1978, 1989-1991, or 1994-1996), the user can see the weight of a single serving of each food item during that time period. This is visually illustrated with an image of the item on a scale.
