cells through a microscope: gray interlocking shapes with indented circles in each one labelled "Nucleus"

An onion cell (seen through a microscope)

You can see individual cells for yourself if you can get access to a regular light microscope, perhaps at your school, or at the science museum. Students often start by looking at an onion cell stained with a little iodine to make the nucleus and the wall easier to see.

You can also get a lens that will attach to your iphone camera that will magnify enough to see cells.

Try looking at your hair, or at a drop of pond water that has bacteria floating in it.
