22 questions
In 1665, an English scientists named Robert Hooke made a simple microscope and looked at a piece of cork, the dead cells of oak bark. Hooke observed small, box shaped structures such as those shown below. He called them cellulae (Latin for small rooms) because the box like cells of cork reminded him of the cells in which monks live at the monastery.

During the late 1600s, Dutch scientist Anton van Leeuwenhoek, inspired by a book written by Robert Hooke, designed his own microscope. To his surprise he saw living organisms in pond water. Watch at least 20 seconds of this live microscope video of pond water then answer the questions. (Ignore the annoying music)
