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.

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.

What a packed instructional activity! 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...

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...

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

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.

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.

Demonstrate the ratio of surface area to volume in your high school class by using phenolphthalein, gelatin, and an onion. Intrigue the class by leading a discussion on osmosis and diffusion, then making "scientific jello." Participants...

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...

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 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...

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.

Students model and differentiate between the processes of mitosis and meiosis. In partners, they use yarn and construction paper to create models for each of the phases of mitosis and meiosis then compare the chromosome numbers in each...

Seventh graders explore the cell cycle. They view pictures of different stages of mitosis and explain why cells reproduce. They identify the five phases of mitosis: interphase, prophase, metaphase, anaphase, and telophase.

Students will be able to identify the different stages of the eukaryotic cell cycle as well as the different stages of mitosis in the proper order. Students will also be able to recognize what organelles of the cell are integral to...

Students 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 calcualte...

Students use the internet to research how the time of day affects the tides. They work together to develop a demonstration of the tide patterns for a month. They create a chart showing the relationship between tides and the phases of...

Students discover through whole-class role play, the process of mitosis. They will all become a chromosome and demonstrate how they line up 23 to 23.

Eighth graders are able to define meiosis. They are able to compare and contrast meiosis and mitosis. Students are able to state the phases of meiosis. They complete a K-W-L chart on meiosis and mitosis. Students talk about meiosis...

Students compare and contrast the cell cycle of frog eggs, normal cells, and cancer cells. They watch a video about early development of the frog embryo, generate a hypothesis in small groups, and listen to a teacher-led lecture. ...

Tenth graders examine the process of mitosis on a laser disc. They examine mitosis in an onion utilizing the microscope.

Young scholars 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.

Students study what happened to the dinosaurs and possible causes of extinction.  In this investigative lesson plan students create dinosaur eggs.
