DNA Fingerprinting through a Chemistry Lens
Students explore DNA and restriction enzymes using fragments of DNA separated by electrophoresis on an agarose gel. They analyze the results to see "whodunit".
Curated OER
Extraction of DNA from White Onion
Students investigate techniques involved in extracting and isolating DNA. Students extract and observe onion 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.
Curated OER
DNA Recombination II
Students model recombination in DNA. They color the DNA sample and cut it out. Students use their "restriction enzymes" to cut the DNA into specific fragments. They separate the fragments using the "gel electrotrophoresis." Students...

Who Done It?
Pick and choose which activities to include in this crime scene investigation. Junior detectives can examine fingerprints, DNA, blood samples, or bone structure. The plan suggests you have teams solve a mystery, but it does not give you...
Curated OER
Who's Who and How Do You Know for Sure?
Students investigate the applications of DNA fingerprinting, They read crime scenarios and using the details of the crime and laboratory experimentation decide the suspects guilt or innocence.
Curated OER
Edible DNA
Pupils use multicolored soft candies (gumdrops and candy orange slices) and toothpicks to create models of DNA structures. They discuss the fact that DNA must copy itself before splitting into two cells. Students demonstrate this by...
Curated OER
How Cells Duplicate and Why Where Something Can Go Wrong
Seventh graders explore the function of a cell and cell division. In this investigative lesson students construct a 3-D model of a DNA molecule.
Curated OER
A Spool Of Thread
Students describe a spool of light colored thread that the teacher holds in his/her hands. They are asked what substances (cotton and wood) are present and what structures (thread and spool) are present. The teacher conclude that the...
Curated OER
Constructing a Phylogenetic Tree
Students are given the opportunity to analyze DNA sequence differences between organisms in order to establish a reasonable picture of the evolutionary relationships between them (Phylogenetic Tree). In the simulation form they are...
