Students extract DNA from an onion using household equipment and supplies.

Students extract DNA from green peas. In this DNA extraction lesson plan, students use a blender to chop up peas, they mix them with a little soap, they tenderize them and they mix them with alcohol to see the DNA precipitate through the...

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.

DNA is the code for all biological traits, both plant and animal. Using an exploratory lesson, learners begin to explore the concept of a biological code by decoding word puzzles. They then extract DNA from plant cells using detergent to...

High schoolers 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.

Students study DNA by isolating it from plant tissue. They determine the purpose of each step in the isolation procedure as it relates to the physical and biochemical characteristics of the genetic material

High schoolers investigate techniques involved in extracting and isolating DNA. Students extract and observe onion DNA.

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.

Mr. Bergman has been murdered and we need you to solve the crime! The cross-curricular unit covers 11 different types of forensic science and includes 17 activities. Scholars perform blood type analysis, blood spatter analysis,...

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.

Students, working in cooperative groups, extract very impure samples of DNA from a number of tissue samples. They determine how the samples can be preserved and how they are similar.
