In a fun and interactive two-day lesson, learners sort anole lizard pictures by appearance. Next, they watch a video about the anoles and re-sort based on the information in the video. In addition to physical characteristics, budding...

Students analyze DNA sequence differences between organisms in order to establish a reasonable picture of the evolutionary relationships between them. They take the role of molecular biologists and make genetic changes and constructing...

Get your class to take a closer look at DNA. Pupils conduct research to determine the methods used by scientists to analyze the molecular structure of DNA. The class members investigate different types of molecular imaging along with gel...

Learners interpret different DNA fingerprints, then do a jigsaw activity to explore other uses of DNA forensics. They listen to a radio program about using DNA as evidence and discuss the limitations of and problems with DNA testing.

High schoolers complete a study guide using a website which is an animated primer on DNA, genes, and heredity. The Web site is organized around key concepts. The web links and study guide are included.

What do you have in common with a fruit fly? About 60 percent of your DNA. The resource, divided into two units, is intended for grades four to eight and another for high schoolers. Both units include eight lessons covering the...

How does HIV operate at the molecular level? Pupils discover the progression from a healthy immune cell to one infected with HIV, watch an animation of the HIV life cycle, and finally identify each of the stages with illustrations...

Students gather information about gene sequencing. In this biology lesson, students use the Internet to access information about gene sequencing, then work in pairs to read and record a gene sequence. Lesson includes extension activities.

Junior biologists compare the amino acid sequences from fragments of five different globin molecules. They count the letter differences between each species pair. They construct a graphic representation of the evolutionary relationships...

Middle schoolers expand on and elaborate about the field of genetics.

High schoolers explore issues surrounding DNA microarray technology. They focus on a single area of biomedical research to help them explain how science, people, ethics, and history all fit together. They analyze gene-expression data.

Students discover what they need to know about DNA chips. They extend this knowledge to analyze gene expression data to diagnose two kinds of leukemia.

What will your class learn in a curious tale of a fungus, a virus, and a chestnut tree? Biology scholars discover the world of viral biocontrols through a DNA restriction lab. Groups research the decline of the American chestnut tree at...

Pupils write an essay on the basic steps of the DNA replication process accurately enough to show a complete understanding of the subject. Finally, student correctly identify the polarity of the template strand and match the correct base...

Students study southern blotting and its uses. They research on restriction enzymes and their uses, especially in relation to recombinant DNA. In addition, they write a summary and an interpretation of the gel.

Students use the SEE strategy to visually organize data.

Students analyze the results of a hypothetical cloning experiment using a restriction endonuclease map obtained from an on-line data source. They answer the question, "How can I tell if the DNA I have obtained from this hypothetical...

Students explain the concept of gene sequence analysis. In this gene lesson, students draw inferences about phylogenetic similarities of different organisms.

Learners formulate a hypothesis regarding the validity of the current status of the Arizona Hedgehog cactus as a distinct variety of cactus. They design a procedure to isolate DNA from the tissue of plants, given a list of chemicals and...

Students participate in a teacher-guided activity to teach about protein synthesis. Student roles include one person as the DNA molecule, another is a single stranded sequence of complementary mRNA.

Students engage in a lesson that is about the DNA molecule and focuses upon the sequencing of proteins to identify individuals. They conduct research using a variety of resources and then complete the activities included in the 3 parts...

Students compare the amino acid sequences in cytochrome-c for a variety of organisms and use this information to infer evolutionary relationships. They investigate the role of homeobox genes and what this indicates about the evolution of...

Students describe a spool of light colored thread that the teacher holds in his/her hands. They are asked what substances (cotton and wood) are present and what structures (thread and spool) are present. The teacher conclude that the...
