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...

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...

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...

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.

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...

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.

Students 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 cloning.

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...

Students 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. Students work in pairs to create one stage using pipe cleaners, sequins,...

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.

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 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 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. 

High schoolers use high powered dissection microscopes to dissect and examine frog embryos as well as see balls of cells that were produced by rapid division. The concept of mitosis links to the lesson plan.

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....

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 explore the cell cycle. They examine why the cell cycle is necessary. Students discuss the processes of interphase and mitosis. They explore the general phases of mitosis; prophase, metaphase, anaphase and telophase.

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.

Tenth graders work in teams to order events of DNA transcription and translation protein synthesis. In the second lesson, they put the steps of mitosis and meiosis in order using a concept map poster. They use modeling clay to create...

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...

Eighth graders study the importance of cell division, compare cell division in prokaryotic and eucaryotic cells, identify the stages of mitosis and recognize meiosis in reproductive cells.
