Watch as an animated cell goes through the process of mitosis as DNA coils and bunches into chromosomes. Once the nuclear membranes dissolve, spindles pull chromatids to opposite sides and stretch the cell. The video ends as mitosis...

Paul Andersen conveys the complexity of the cell and its organelles, explaining the function of each in detail. Hear how all the parts work together to help a eukaryotic cell operate. Use this video in a high school biology class for an...

Paul Andersen uses beads to demonstrate mitosis and meiosis. He explains the differences between the two and physically moves the beads around to represent the pulling apart of chromosomes and duplication. Get a clear understanding of...

This quiz just looks neat! It has two cell diagrams for biology class members to label. They also describe the function of each organelle. A prokaryotic and eukaryotic cell are displayed for them to compare, and then they fill in the...

Students observe slides of cork cells and discuss the use of microscopes. They view a power point presentation on "Looking Inside Cells" and take notes aligned with the PPT presentation. They collaborate with a partner to create an...

Get up close and personal with human cells with this lab worksheet. Learners use a microscope to examine their own cheek cells, drawing diagrams of the cells and identifying the parts when they have focused in on a visible specimen....

Your students should enjoy this slideshow which includes some basic definitions about the atomic structure of atoms. In fact, this presentation would be best-viewed before giving details and diagrams of neutrons, protons and quarks. The...

Watch as cells split beneath a microscope. This nineteen-second clip does not have narration or music, but it gives a fascinating look at mitosis. Use this in a high school biology class to demonstrate what mitosis really looks like.

This quick clip of a lung cell splitting under a microscope is rapidly discussed as it is shown. Microscopic imaging lends us a thrilling close-up of the mitotic process as it is explained. Show this clip to an advanced biology class.

Cellular transport and activity are highlighted with vivid images taken by a microscope. Some animation and other footage is shown as well to discuss the inner workings of a cell. Begin your biology class with this introduction to cells.
