Learning to Look, Looking to Learn - Peeling Onions
Lilly Martin Spencer's "Peeling Onions" is the subject of a series of exercises that model for learners how to use the elements of art to read a painting. A series of worksheets focus viewers' attention on how Spencer uses color and...
Curated OER
Discovering Mitosis in Onion Roots
Learners 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.
Curated OER
Onion: Print and Color
In this word recognition worksheet, students trace the word "onion", write the word independently, and color the picture of the onion.
Curated OER
Comparing Apples and Onions
Fifth graders observe heredity. In this Science lesson, 5th graders are introduced to the concept of traits being passed from parents to offspring. Students investigate the concepts through apples and onions.
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.
Curated OER
DNA Extraction From Onion
Students extract DNA from an onion using household equipment and supplies.
Curated OER
You...Instead of the Onion Skin
Learners observe their own epithelial cells from the inside linings of their cheeks using DigiScope technology. They prepare a slide with both onion cells and epithelial cells and make an illustrated booklet for a PowerPoint presentation...
Virginia Department of Education
The Cell Cycle and Mitosis
What a packed lesson plan! 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...

Point of View: Comparing Esperanza's and Isabel's Perspectives About Life in the Camp (Chapter 7: "Las Cebollas/Onions")
Explore point of view and more with a Common Core-designed instructional activity. Learners experience different points of view by representing one of two characters from Esperanza Rising during a partner discussion. They must use...
Curated OER
Onion Cells
Students observe the cells of an onion by wet mounting it and viewing it in a microscope. In this hands on lesson students make their own wet mount slide of an onion and are able to identify the cells in it such as, the nucleus,...
Curated OER
Onion Skins
Students explore the structure of a plant cell. They carefully peel a single layer of onion skin from a slice of onion and stain it with methylene blue to observe the structures inside. They use a Digiscope connected to a computer to...
Curated OER
ISOLATION OF DNA FROM ONION
Learners perform a laboratory exercise designed to show how DNA can easily be extracted from onion cells. They conduct an optional test for the presence of DNA using standard lab equipment.
Curated OER
A Hidden Beauty
Expose the beautiful mystery of bulbs as young botanists learn all about these fascinating plants. They glean information from a short text before observing actual bulbs (consider an onion), and comparing their findings with predictions....
Curated OER
Cell Size and Shape; Diffusion and Osmosis Processes
Use salmon eggs as a cell model for demonstrating the movement of water over concentration gradients. Junior scientists examine the same process microscopically with an onion cell. They use a thistle tube and a semipermeable membrane to...
Baylor College
Magnifying and Observing Cells
Though it isn't a novel activity to prepare onion cell and Elodea plant cell slides as examples of cells in a microbiology unit, this resource will leave you thoroughly prepared. As pupils examine the slides that they prepare, they draw...
Curated OER
Taco Grande
What do you use to chop an onion or brown the meat? Learners with special needs read through a taco recipe, then use it to complete three different academic development activities. They circle the best utensil for the job, match each...
Curated OER
Mitosis and Cancer - Biology Teaching Thesis
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...
Virginia Department of Education
The Ratio of Surface Area to Volume
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...
Curated OER
Cell Division and Mitosis
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.
Curated OER
Comparing Apples and Onions
Fifth graders observe and compare apples. In this apples instructional activity, 5th graders work in groups to record the physical characteristics of a variety of apples. Students predict each apples weight and then weigh them to see if...
Curated OER
Extraction of DNA from White Onion
Pupils investigate techniques involved in extracting and isolating DNA. Students extract and observe onion DNA.
Curated OER
ISOLATION OF DNA FROM ONION
Students perform a lab in which they extract DNA from onion cells. Students break through the cell and nuclear membranes and then break down the protein that the DNA is wrapped around.
Curated OER
Extraction of DNA from Onion
Students experiment with DNA by isolating it from plant tissue. They investigate whole onions to prepare DNA. They complete the experiment to examine the structural characteristics of DNA.
Curated OER
Extraction of DNA from White Onion
Students conduct lab test with minced onion to determine where chromosonal DNA is located within the cell, and whether or not it can be extracted.
