DNA: The Human Body Recipe
Students describe DNA and the roles in which engineers are involved with the human body. In this DNA lesson students participate in a class demonstration.Â
Curated OER
How Cells Reproduce
Students explain why cells reproduce and draw a diagram of each of the stages in mitosis. They put the stages of mitosis (interphase, prophase, metaphase, anaphase, telophase, and cytokinesis) in the correct sequence, from the beginning...

Cell (Biology)
Students conduct a series of activities to explore the nature of cells. In this biology lesson, students observe plant and animal cells under the microscope and compare them. They differentiate osmosis and diffusion.
Curated OER
DNA Extraction
Students extract and observe a visible amount of DNA from Escherichia. coli cells. They discuss the properties of DNA. Confirmation of the presence of DNA by a reaction with an indicator is confirmed within this activity. Many hands-on...
Cornell University
Plant Cell Crime Scene
Use science to solve the mystery of the Poplar murder. Pupils use forensic botany to determine if a suspect could be the killer. By analyzing images from a Transmission Electron Microscope, learners determine if the material found on the...

Investigating DNA
Students engage in a variety of activities designed to facilitate the understanding of DNA. Activities include preparing human chromosome spreads, separating a mixture of dyes using gel electrophoresis and extracting DNA from onion cells,
Curated OER
DNA Extraction with Kitchen Chemistry
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...
Howard Hughes Medical Institute
Stem Cells and Diabetes
Students investigate stem cells. In this science lesson, students discuss stem cells and view a video about human embryonic development. Students conduct the pulse-chase.

Learning the Structure and Function of DNA
Young scholars read about Humane Genome Project, examine structure and function of DNA, and participate in gel-electrophoresis lab. They complete Internet activity to test their knowledge of DNA.
Curated OER
The Structure of DNA
Students describe the structure of the double helix, explain how DNA copies itself, and recognize that the sequence of DNA is what makes each individual unique.
Curated OER
DNA Models
Young scholars create DNA models. Using puzzle pieces to represent the parts of a DNA strand, they put together a segment of DNA. Once everyone has completed their individual strand, they being linking with other students using tape. ...
