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...

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 review the basic principles of plant cell structure, tissue culture, sterile technique, and cell transformation. Next students complete a plant transformation experiment using whole plant material in order to view evidence of...

Learners explore the role of enzymes in chemical reactions. In this enzymes lesson plan, students use hydrogen peroxide and manganese dioxide to observe a chemical reaction. Learners observe the rates of reactions of chalk, hamburger,...

Students are able to identify start and stop sequences in DNA. They are able to model using restriction enzyme and ligase to remove sections of DNA and reattach them. Students are introduced to the process of recombinat DNA through the...

Students draw a diagram to show the fluid mosaic model of a membrane. They explain how hydrophobic and hydrophilic properties help membranes hold their shape. They identify the functions of different cell membrane proteins as well.

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.

Students define the key terms that are the structure and function of DNA. In this genetics instructional activity students complete a lab activity in which they construct a model DNA structure.

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.

Students explore biotechnology through various activities. In this biology instructional activity, students analyze its pros and cons. They study and read informative articles about biotechnology.

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 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...

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 investigate the process of genetic engineering. In this genetic engineering lesson plan, students use paper models of DNA and plasmid bacterium to investigate the process of replicating DNA, splicing genes from DNA, and...

Students construct various virus models using Fruit loops and Alphabits to represent nucleotides and molecules. They constructs capsomeres using shoes as the capsomeres and discuss various viruses.

Students are introduced to DNA microarrays. They discuss how scientists and doctors use them and how they work. They complete a worksheet and discuss their findings.
