Discovering Mitosis in Onion Roots

What a packed lesson! Provide your class with the opportunity to learn about the cell cycle in several exciting ways. Biologists first learn about the theory behind mitosis, then proceed to view onion tips under the microscope and create...

Plumb the depths of the Submarine Ring of Fire and explore seismic waves with this lesson. Junior geologists simulate s-waves and p-waves, calculate their speeds, and then apply the data to discover the material that makes up inner...

Searching for simple ways to teach mitosis to high schoolers? Using colored chalk and onion root tips, pupils visually demonstrate what they view when looking through the lens of a microscope. There are also various ways to expand the...

Young scholars discover the processes that occur during mitosis and what makes each phase different and distinct from the others as well as how each contribute to the overall process of mitosis by looking at onion root tips under a...

Observe onion root cells undergoing mitosis underneath a light microscope and determine the phase of mitosis the cells are in. High schoolers draw a sketch of the mitotic cells, explore why cells undergo mitosis and learn how...

Although we cannot clone ourselves yet, our bodies make copies of our cells every day. The video begins by defining diploid and haploid. Learners see the cell cycle and begin to understand what happens in interphase before mitosis...

You slough off all your skin cells once every seven years. Thank goodness for mitosis, or we would all be looking pretty strange without skin. The video begins by reviewing the cell cycle, looks at an overview of cells undergoing...

Paul Anderson gives an explanation of how to conduct a biology lab to see mitosis and meiosis. This clip is directed at teachers and shows how to use an onion root and the fungus sordaria to count up the phases and draw a cell cycle pie...

Students conduct an experiment to determine how the absence of a root cap affects a plant's ability to sense gravity. They make comparisons between capped and decapped roots.

Online mitosis activity offers the student the opportunity to identify, classify, calculate, and graph the phases of mitosis. Explanations of each phase, actual cells are displayed for classifying and gathering data in this comprehensive...
