Investigating Enzymes Used in Laundry Detergent
It's a win-win situation: learn about enzymes and get clean clothes, too. Young scientists add enzymes to a dilution of laundry detergent. They apply them to stained fabrics to determine the effectiveness of the enzyme-filled detergents.
Curated OER
Gelatin and Enzyme Lab
Students observe the effectiveness of detergents on breaking down proteins. In this investigative instructional activity students participate in an activity that shows how proteins are broken down in gelatin and fill out a worksheet.

Extracting DNA from Living Things
Help! Someone's trying to take my DNA! An interesting lab experiment has scholars use basic materials to extract DNA. By applying ethanol, cold water, and a protease enzyme, like pineapple juice, they pull strands of DNA from peas,...
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
Amylase
Students examine what amylase is and its history. For this digestive lesson students study the effect amylase has on starch and how temperature affects the rate of activity.
Curated OER
Molecular Explorations
Students explain the processes for separating DNA from tissue and separating complex mixtures. In this exploratory lesson students complete a lab where they extract DNA.
Curated OER
There's Always Room For Jell-O
Students explore the breakdown of proteins. They cut wells in Jell-O and observe as the detergent digests the Jell-O. Students record their observations and take measurements.
Curated OER
The Cloning of Plasmid and Spinach DNA
Young scholars will first extract genomic DNA from spinach and perform a restriction enzyme digestion on both the spinach DNA and the plasmid using the same restriction enzyme. They then ligate the cut plasmid DNA with the cut spinach...
Curated OER
Cloning of Plasmid and Spinach DNA
Young scholars ligate fragments of genomic DNA from spinach into a vector plasmid. They perform a restriction enzyme digestion. Student use a ligated DNA molecule to transform E. coli cells. Students analyze their procedures and...
Cornell University
Extracting DNA
Uncover the basics of DNA structure through exploration activities. Collaborative groups build DNA models and recreate the process of replication. Then, using plant cells such as peas or strawberries, they extract a DNA sample.
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...
Curated OER
DNA Extraction
In this DNA extraction worksheet, high schoolers learn how to extract DNA from various foods. Students complete 2 short answer questions.
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
Molecular Evolution in Plants
High schoolers are using a paper chromatography study that is suitable for introductory biology. The absorption spectra studies and gel electrophoresis studies are appropriate for students who have complete both introductory biology and...
Curated OER
Molecular Evolution in Plants
Learners examine chlorophylls. They explore the absorbing pigments in a variety of plants. Through activities, students determine spectrophotometrically. They compare plant proteins from the family Brassicace to assess the level of...
Curated OER
DNA Extraction From Living Things
Students extract DNA from split peas. In this biology lesson, students hypothesize what DNA looks like and perform the experiment to verify their hypothesis. They explain the importance of DNA in living things.
Curated OER
DNA Extraction Laboratory Experiment
Students will visualize how DNA is extracted from cells by performing a simple laboratory experiment. They will then use this knowledge to further understand how scientists are using DNA extraction to try to clone human cells, and to...
