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 explore DNA restriction mapping. They cut pieces of paper into lengths representing those produced when specific enzymes are used to cut a strand of DNA.

High schoolers investigate the enzyme catalase. In this enzyme lesson plan, students observe a normal catalase reaction, they observe liver tissue, potato, chicken and apple for the enzyme catalase and they study the effects of...

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...

Learners use the prelab as an introduction to the importance of DNA fingerprinting- a form of identification that us being accepted by both scientific and leagl experts. They prepare a gel for electrophoresis. DNA fragments, which have...

In order to understand DNA fingerprinting, advanced biology aces divise a crime scenario and analyze three different samples of lambda DNA. This creative lesson plan provides practice with micropipettes, electrophoresis boxes, and other...

Pupils examine the effects of specific enzymes on samples of liver tissue, muscle tissue (chicken), apples, and potatoes.

Pupils are allowed to strip away the cell walls of plants cells (using enzymes) and then observe the resulting spherical protoplasts (plant cells minus the cell wall). They see that plants cells indeed have a plasma membrane in addition...

Students 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.

Students analyze the calcium content of egg shells as an introduction to the toxic effects of pesticides on biological systems.

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...

Students recognize different consumer products, found in and around the home, that have reactive or denaturing properties when used together. They explore chemical and physical properties of each product by identifying chemical formulas...

Students work with whole plant material and are not required to measure small quantities, yet they can see evidence of transformed plant cells (plant cells that have genes from bacterial plasmids). This is a laboratory suitable for...

Students are able to distinguish between transcription and replication. They are able to distinguish between DNA and RNA. Students name some of the proteins and enzymes used in replication and transcription. They are able comprehend the...

Students experience a "hands-on" activity to get visual evidence of the physical nature of DNA and the process of DNA purification. They explore one method of chromosomal DNA isolation and DNA extraction.

Fourth graders model the activity of an enzyme acting on a substrate and observe relationships. Have students place toothpicks in a pile. One member of the team should break as many toothpicks as possible, in 10 seconds.

Students perform an experiment that measures respiration.  In this performing an experiment that measures respiration lesson plan, students discuss aerobic and anaerobic respiration.  Students measure the gas produced by...

Biology learners investigate the effect of sucrose concentration on yeast alcoholic fermentation. During the lesson,they compare and contrast the processes of cellular respiration and alcoholic fermentation. They design an experiment to...

Students conduct an experiment that allows them to assess individual differences in random DNA sequences and apply those differences when solving a forensic problem. After discussing the polymerase chain reaction and its use to identify...

Students list differences between DNA-related terms and create a simple DNA circle map. They order terms including human body, organ, tissue, cell, nucleus, etc. from largest to smallest. They discuss differences and similarities among...

Students create numbered DNA sequences by taping together the order of the sequence. They count the number of bases in their RFLP's and shade the boxes on their Gel Electrophoresis sheets that represent individual fragments. They...

Pupils use limited data and their prior knowledge to solve problems focused on various inhibitors of respiration in this lesson plan on cellular respiration in a molecular level. This lesson plan includes a student handout and a...

Students use this lab as a follow up to the introduction of the ecosystems and productivity levels, bioassays and what and how they measure, and Daphnia magna as an index organism, i.e., a species whose health within an ecosystem...
