Students investigate the uses of pesticides and the pros and cons of their use. In this pesticides lesson, students observe simulations of the three classes of pesticides and the effects or actions each has. Students answer 3 follow up...

Young scientists or chefs culture yeast to produce yogurt. The materials and a general description of how make yogurt are provided, but there is very little detail otherwise. You could use this as an activity when your biology class is...

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.

Students observe the experimental process called bacterial transformation and demonstrate phenotype changes in bacteria that have been transformed with an antibiotic-resistance gene and a metabolic marker. They create a luminescent...

Students grow E. coli strain HB101, which contains the plasmid pUCD607 with the bioluminescence (Lux+) gene. The plasmid containing the Lux+ gene is isolated from the E. coli, then characterized by restriction analysis.

This is not they typical set of teacher instructions. It is an organized chart of the important organic compounds. For each, the involved elements, the name of the building block monomers, the names of polymers, extra information, and a...

In this living environment worksheet, learners answer 30 multiple choice questions and 42 short answer questions in preparation for the Regents exam.

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...

Young scholars are taught how enzymes enable chemical reactions to occur a body temperature and how the lack of enzymes in the body can cause problems in the break-down and absorpion of nutrients. They match up different enzymes with...

Students explore the effect enzymes have on reactions. They demonstrate the process of enzymatic reaction by making cheese. after experimentation, they answer a series of questions.

Students listen as the teacher tells the story of Sisyphus rolling the stone up the mountain. Students prepare two batches of jello, one with fresh pineapple, and one with canned pineapple. While the jello is setting, students work on...

Students explore DNA and restriction enzymes using fragments of DNA separated by electrophoresis on an agarose gel. They analyze the results to see "whodunit".

Students design and conduct an experiment to test their ideas about how to speed up or slow down the rate of an enzyme-catalyzed reaction. They have access to an array of physical and chemical factors that might influence enzyme...

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 identify the steps in a gel electrophoresis experiment and describe the role of enzymes. They examine the relationship between fragment size and migration rate in a gel. They view DNA fragments as well.

Students develop and run a laboratory comparing alcohol tolerance in flies with and without the ADH enzyme.

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

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...

Seventh graders demonstrate the processes of science by posing questions and investigating phenomena through language, methods and instruments of science. They study the body features or systems of several animals.

Students perform restriction digests on DNA samples from four individuals, and then search for similarities between the individuals by running the restriction fragments on an electrophoresis gel.

Students analyze various beverages to determine vitamin C content. Students research diseases resulting from vitamin C deficiencies and identify countries most affected.

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...

Investigate the relationships between different deep-sea organisms by DNA sequencing. A worksheet provides instructions for DNA sequencing and space to work. They simulate gel electrophoresis by cutting out paper "DNA strands."...

High schoolers played a game of Jeopardy where there was five categories with five questions each in order to assess the retention of concepts taught over the semester. The categories included: Graphing/Summarizing/ Scientific Method,...
