I have always wondered what the spleen did. For most organs I can rattle off a sentence or two about their function, and now I can do the same for the spleen. It is a recycling center for red blood cells. The iron and amino acids are removed from worn out red blood cells in the spleen before the wastes are sent to the liver for disposal. If you've been following this blog it's no surprise that I learned this by reading David Macaulay's The Way We Work book.
This activity was many steps long but lasted less than one hour. Getting the kids hands involved really helped them to understand the purpose of the Spleen.
