Students discuss the functioning of the digestive system and the specific enzymes present. They observe the action of amylase on starch to identify characteristics of enzymes then perform an experiment on the effects of temperature on...

Tenth graders test their saliva for enzyme activity. For this enzyme lesson, 10th graders conduct an experiment to test the enzymatic activity of their saliva. They relate the lack of certain digestive enzymes with alcoholism.

Enzymes in our bodies each have a job to do. Learn the factors that affect the activity of some enzymes using the third activity of an informative 12-part biology series. A three-part laboratory activity asks teams to investigate how...

Students test for the presence of enzymes in fruit and the specificity of those enzymes, as well as to identify and show the susceptibility of enzymes to certain environmental factors (temperature and pH) originating in the enzyme's...

Young scholars participate in a modified demo enzyme lab, a "magic show." The purpose of the demo is to tickle the curiosity of the student and grab their interest before discussions of enzymes. Its purpose is also to stimulate problem...

Student demonstrate knowledge of recombinant DNA techniques (restriction enzyme digest, gel electrophoresis, and staining gel). They demonstrate skills needed to complete a gel electrophoresis and interpret a stained gel. Pupils solve...

Students conduct a variety of experiments to explore gel electrophoresis. For this biology lesson, explain how this process separate DNA and RNA. They discuss the practical applications of this method.

Young scholars test for the presence of enzymes in fruit and the specificity of those enzymes. They identify the susceptibility of enzymes to certain environmental factors such as temperature and pH in the enzymes environment.

Biochemists experiment with the oxothermic decomposition of hydrogen dioxide by adding manganese dioxide. They observe how pepsin enhances the action of acid on the digestion of egg white proteins. They use yeast to make bread rise. All...

Students compare different DNA and run a gel electrophoresis.  In this DNA instructional activity students complete a DNA activity that allows them to better understand its structure and function. 

Students watch a demo which is a modification of an enzyme lab which is done as a "magic show". It's primary purpose is to tickle the curiosity of the student and grab interest before discussion of enzymes. It is also used to stimulate...

Students demonstrate the path of food in the body. In this biology lesson, students conduct an experiment to determine how large the the digestive system is. They name the different organs involved in the digestive process.

Seventh graders explain the mechanism of digestion. In this biology lesson, 7th graders perform an iodine test to check for the presence of starch. They discuss how energy travels through the food chain.

Students extract DNA from their own hair roots. They run an electrophoresis gel to examine patterns of their DNA along with standard DNA. The experiment is based on a crime scene scenario.

Biology stars extract DNA samples from beef thymus and then examine its properties. They use enzymes to digest the DNA samples, and then use electrophoresis to separate fragments. Finally, they discuss methods and principles of...

Young scholars applied various mathematical analyses to interpret their data. By using the resulting DNA fragment patterns from several enzymes students established a possible evolutionary relationship among the mice.

Students demonstrate that many of the enzyme systems needed to break down--and therefore clean up-society's wastes already exist in nature among the decomposers. They select the best starch-munching organisms by altering the environment...

Students use this laboratory exercise, restriction enzymes to recognize a four-, six-, and eight-nucleotide sequence. Assuming that the four component nucleotides (A, C, T, G) are distributed randomly within a DNA molecule, then any...

Students 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 outcome of...

Students 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 DNA in...

Pupils investigate the use of restriction enzymes to recognize a four-, six-, and eight-nucleotide sequence. They utilize restrictive endonucleases to cut Thymus DNA and compare results by viewing the DNA fragments on Agarose Gel...

Students conduct an experiment to demonstrate that many of the enzyme systems needed to break down society's wastes exist in nature among the decomposers in a compost pile. They culture compost bacteria on starch agar to examine the...

Second graders discuss worm composting. In this decomposition instructional activity, 2nd graders look at the anatomy of the worm and how it eats food. They have their own worm bin and review what foods can and can not be given to the...

Young scholars study fungi and its characteristics.  In this fungi lesson students collect and observe fungi then answer questions on what they saw.
