Jello Cells...Yum!

To begin our study of the human body, we are learning about cells, the building blocks of, well, everything. We're using:
The Kingfisher First Human Body Encyclopedia (Kingfisher First Reference)
and also Body systems and organs: Covering system, skeletal system, muscular system, circulatory system, respiratory system, digestive system, excretory system, ... system (Step-by-step science series) Really long title for a little paperback workbook!

 We studied pictures of cells and their labeled parts, then decided to make an edible cell. Cuz every lesson is better when you eat it at the end.
 After raiding the refrigerator and cabinets, we came up with stawberry nuclei, gumdrop mitochondria, ribosome sprinkles, and tootsie rolls flattened and curled to look like rough ER. I wouldn't recommend the tootsie rolls - they melted in the jello. We could still see bits of them in there. The ooze wasn't pretty, though.

KID 1 adds ribosome sprinkles

KID 2 drops in mitochondria gumdrops

Our cells are ready for cryofreezing...or cryofrigerating in our case.


We put a cell on a glass plate and held a light under, huh?
