Vitamin B1 - About

The Chicken Farm educational game and related reading are based on the 1929 Nobel Prize in Physiology or Medicine. No one had heard of vitamins until Christian Eijkman pointed out that a substance in rice skin was missing from the diet of beriberi patients, which was later discovered to be vitamin B1. This was the first time that an illness was linked with vitamin deficiency.

Chicken Farm Game

- Why do we need vitamin B1?
- What food contains vitamin B1?
- What is the disease beriberi?

This fast-paced game relies on a keen knowledge of food containing vitamin B1 and good keyboard skills to save lives.

You have one minute to feed chickens suffering from beriberi with the correct food to stop them from dying. If you are too slow, or provide the wrong food, the chickens will collapse and die. Cure them quickly, and you could end up on the list as "the fastest feeder this month"!

About the educational games

The educational games are based on Nobel Prize awarded achievements and were produced between 2001 and 2012. Most games have not been updated since production (including potential scientific facts changes) and are provided here on an 'as is' basis by popular demand.

Some of the games run in modern browsers without the need of any plugin (either as a new version or using Ruffle), but many of the games still require Adobe Flash Player. Flash is an old technology that has reached end of life. These games will no longer work without a dedicated setup. If you are depending on these games in your profession, please advice your local IT support. We do not have the resources to provide support.

We are working on supporting more games without Flash.
