Play the Cell Size SIM Certain cell types should have a general size and have proportionate parts. But what if those sizes and proportions are different than they should be? The size of the nucleus versus the size of the cytoplasm in a cell is an important measure – it can tell us if something might be wrong with that cell. Explore more about this "NC ratio" in Cell Size SIM. To learn more about cells, visit The Building Blocks of Life.

Play the Keys to the Ocean Game Our world is full of different plants, animals, bacteria, and other life. But how do we know which species is which? Scientists have built tools called taxonomic keys that help us do this. Take a trip to the ocean to help researchers identify different species of fish and zooplankton in Keys to the Ocean. To learn more about taxonomy and species identification, visit our story page about Taxonomy.
