High schoolers explore the process of chemosynthesis and relate it to the biological communities in cold seeps. In this biochemistry lesson students interpret analyses of enzyme activity and draw inferences about organisms in cold seep...

Learners simulate gene splicing by examining bacteria. They create a bacterial DNA into which they insert the human DNA (gene) that codes for growth hormone. They cut the sites of the enzyme to study how the human DNA can be joined to...

For this nutrition worksheet, students review the organs and enzymes that are part of the digestive system. Then students review the food pyramid by comparing two menus. This worksheet has 9 fill in the blank, 4 true or false, and 5...

In this genes worksheet, students review the system that controls gene expression and the enzymes required for regulating genetic expression. This worksheet has 6 fill in the blank and 7 short answer questions.

In this replication worksheet, students color in the nucleotide outline and the enzymes plus the base pairs to show the replication of DNA.

Substances that decompose with the help of living organisms do so at different rates. Scholars experiment with Winogradsky columns to determine the rate of decomposition, the oxygen and sulfide content changes, and bacteria levels. The...

In 1993, Phillip Sharp and Richard Roberts won the Nobel Prize for their discovery of split gene theory. Learn about the breakthrough with the help of an online interactive. Hear both scientists explain it in their own words, watch an...

In this saliva worksheet, high schoolers conduct an experiment to test how saliva breaks down starches. Students complete 6 short answer questions.

In this DNA technology worksheet, students will review 12 vocabulary words relating to the uses and results of DNA technology in this crossword puzzle.

In this metabolism worksheet, students name the two mechanisms for ATP synthesis and give an example of where this occurs for each. Then they explain what happens during the oxidation of glucose and the three steps. Students also...

In this word search worksheet, students locate 9 words related to biology. The word list includes enzyme, hydrogen, and nucleic acid.

In this genetics worksheet, students compare structures of molecules, compare the function of genetic enzymes, and compare transcription and translation. This worksheet has 2 multiple choice and 20 matching questions.

Fifth graders make cheese using two different methods. In this cheese making instructional activity, 5th graders make rennet cultured cheese following the step by step directions. They also make cheese using a genetically engineered...

Students 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...

Young scholars try to confirm the sequence of a given cDNA clone using the WWW tools and traditional restriction analysis. They grow the clone, prep the plasmid, cut the plasmid with restriction enzymes and compare their results to what...

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...

Ninth graders investigate what restriction enzymes do, and explain how a DNA sample can link a suspect to a crime.

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...

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 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...

Young scholars create DNA models using colored construction papers. In this biology lesson, students identify enzyme restriction sites. They model how DNA plasmids replicate when taken up by a bacterial cell.

How does temperature affect lipase activity? Young scholars conduct an experiment to collect data on the interaction of lipase at different temperatures. They add lipase to a solution of milk, sodium carbonate, and phenolphthalein and...

Biology classes will bubble with excitement as they complete this assignment. Beginning with an informative overview of cellular respiration and fermentation processes, the highlight comes as an experiment in determining the rate of...

Six pages begin with a detailed introduction to meiosis and homologous chromosome pairs. Instructions guide learners through a simulation in which they draw craft sticks marked with autosomes in order to decode the genes inherited by...
