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...

A complete overview of oxidation, reduction, and how electrons are moved in respiration. You could use this slide show to elaborate on the concept of harvesting stored energy, and to summarize the stages of aerobic and anaerobic metabolism.

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 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 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.

High schoolers explore the basic process of natural selection and how people can manipulate that process today. The consequences of natural selection on daily life and the implications of evolutionary biology in basic and applied science...

Learners model recombination in DNA. They color the DNA sample and cut it out. Students use their "restriction enzymes" to cut the DNA into specific fragments. They separate the fragments using the "gel electrotrophoresis." Learners...

Biotechnology is big! Introduce the uses of biotechnology to science scholars with a fascinating, fact-filled unit. The first installment in a series of four biotechnology units covers the role biotechnology plays in human and...

In this DNA instructional activity, students access a website to learn how DNA fragments are separated through the process of gel electrophoresis. Then students model the construction of DNA fingerprints and practice interpreting...

Young scholars explore gel electrophoresis using paper models. They model DNA sequences and shade the boxes on their Gel Electrophoresis Sheet which represent the individual fragments.

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 create a paper model of a plasmid and insert a DNA molecule that contains a specific gene into the plasmid. They complete an actual transformation involving E. coli bacterium and relate the two activities to one another.

Students examine the different parts of blood.  In this human blood activity students work in groups and identify parts of blood and construct a model of human blood. 

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.

Seventh graders study the parts of corn and explore the role of starch.  In this corn products instructional activity students prepare a model of water and stones.

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 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.

Young scholars participate in an activity of a mock electrophoresis using paper chromatography to study DNA and genetic restriction mapping.

In this protein synthesis worksheet, high schoolers use a given strand of DNA to write the complimentary base pairs. They transcribe the message to the RNA and then they translate the message into the proper amino acids using the codons...

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...

In this cells worksheet, learners define 14 words associated with cells. They answer 12 short answer questions about the structure and function of the cellular system.

Students explain how DNA directs the production of proteins.

Students explore the "genetic code." They observe how genes may be manipulated for genetic research, gene cloning, and genetic engineering. In a lab setting, students examine the mechanics involved in cutting and ligating DNAs into a...

Students use their knowledge of DNA fingerprinting to evaluate the use fingerprints in courts, and will address the ethics of establishing a national database of fingerprints.
