Curated OER
Mitosis and Cell Division
Students 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 microscope.

Discovering Mitosis in Onion Roots
Students discover the different stages of mitosis by examining onion roots under a microscope, drawing diagrams of what they see, and organizing collected data in a chart and create a pie graph from their lab data.

Cell Division
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...

Understanding Cell Division
Middle schoolers collect and describe cells from an onion root tip which are undergoing the stages of cell division. They use a ProScope USB microscope to identify and compare cells in five phases of mitosis.
Curated OER
Cell Division and Mitosis
Pupils identify each phase of mitosis and the main characteristics of each. Students prepare a microscope slide with onion root tip. Pupils observe the cell division occurring in the cells and label the mitosis phases observed.

Investigation of Meiosis in Common Plants and Animals
Pupils witness various stages of mitosis through preparing onion root tip slides. With teacher guidance, they learn a great deal through the hands-on process of preparing the slides themselves.

Mitosis
High schoolers explore the four stages of mitosis. They view a prepared slide of an onion root tip undergoing mitosis to identify the stage for each cell in view. They record the number of cells in each stage, graph the results, then...

Cell Cycle
In this cell cycle activity, 7th graders study the various images of the cell cycle. Students then label each picture with the correct cycle. Students then answer several questions about the cell cycle.

Cell Cycle Portfolio
High schoolers work together in groups to complete various stations on the cycles of cells. Individually, they keep their completed work in a folder after following specific instructions on how to complete each experiment. They use the...

Identify the Phases of the Cell
In this cell phases worksheet, 7th graders study the phases of an onion cell. Students write the onion mitosis cell phases on the lines.

Serc: Observing Cell Division
In this activity, learners make microscopic observations of onion root tips, discuss them with classmates, then make detailed drawings that are shared.
