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...

Students 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.

Investigate the ins and outs of cell division with this comprehensive set of activities. Detailed instructions for six different activities and your choice of eight different creative assessments can be found within this resource. By...

Donate old socks for science! Young biologists model mitosis and meiosis, using socks as chromosomes and a balloon as a nucleus. This ingenious idea for modeling cell division will be more memorable to your young biologists than any set...

Seventh graders explore the process of cell division. Students observe an animation of cell division. They draw the phases of mitoses. Students describe the phases of cell division and explain the events that occur during mitosis.

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...

Life science learners view an online animated mini textbook comparing two types of cell division. Working in groups, they use a digital microscope to capture images of cells in different stages of mitosis and meiosis. Then they create an...

Young scholars listen to a lecture covering the process of going from one cell to two cells. Using the textbook, students differentiate between meiosis I and Meiosis II. Young scholars work in pairs to create one stage using pipe...

Learners 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.

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...

Learners identify each phase of mitosis and the main characteristics of each. Students prepare a microscope slide with onion root tip. Learners observe the cell division occurring in the cells and label the mitosis phases observed.

Seventh graders describe the processes involved in mitosis and meiosis. In this life science lesson, 7th graders create chromosome models using strings and beads. They play a jeopardy team game at the end of the unit to review concepts...

The living environment, from the interior of a cell to the complex relationships among populations, is queried in this final examination. Learners examine air pollution maps, cell diagrams, population graphs, and drawings of cells. They...

The New York Regents High School Examinations are comprehensive and include various question formats, including multiple choice and graph analysis. This particular version, the 2008 Living Environment exam, surveys a variety of topics....

Students examine cell division and the process of mitosis.  In this cell reproduction lesson students grow yeast and observe the results, and learn about the career of scientific illustration. 

Students explore ways to turn back the genetic clock. They explore cells and mitosis. Students participate in an activity to create a flip book that will animate the process of mitosis. They explain each stage of mitosis.

High schoolers use microscopes to study live fish embryos and animated diagrams of cell division on the Internet. They see that scientists rely on technology to enhance the gathering and manipulation of data. They create web pages on...

Pregnant women exposed to PAH air pollution increase the risk of obesity in their children. The example of epigenetics, along with others, builds the basis for understanding the process of cell differentiation. Scholars view a video,...

Students study how cancer cells mutate and affect cell division.  In this investigative lesson students view a PowerPoint presentation learn the seven warning signs of cancer. 

Using yarn and chenille stems, lab groups collaborate to model mitosis and meiosis. Brief background information and a vaguely written procedure comprise this outline. More instruction needs to be provided to learners about cell division...

The 2005 version of the Regents High School Examination in ecology is as comprehensive as previous years' exams. It consists of 40 multiple-choice questions on topics ranging from the structure of DNA to interactions within an ecosystem....

Students determine the approximate time a cell spends in each phase of mitosis by counting cells in each phase from a prepared slide. They use a few simple calculations to estimate how long cells spend in each cycle in the body.

This exam covers every topic in a typical first-year biology course. A wide variety of question styles gives high schoolers every opportunity to show what they know. Why start from scratch when a comprehensive final exam is easily...

Seventh graders describe the stages of mitosis. In this biology lesson, 7th graders explain the importance of cell division. They complete an activity packet at the end of the lesson.
