Students will discover how paleontologists study and classify dinosaurs and how evolutionary biologists study the relationships between organisms. Students will use fossil and genetic evidence to investigate evolutionary relationships between living and extinct organisms.

Type: Lesson Plan

This lesson can be integrated with math concepts/practices comparing probability.  The science and engineering concepts/practices are to determine the probability for genotype and phenotype combinations using Punnett Squares and Pedigrees.

Type: Lesson Plan

This is an introductory lesson for middle school genetics with a focus on vocabulary development and conceptual understanding.

Type: Lesson Plan

The nucleus of the cell contains genetic material known as DNA. Sections of DNA are genes that code for specific traits and DNA coils to create chromosomes. Students will be able to define DNA, chromosomes, and genes. Students will also create a model to show how these structures are related and where they are found in the cell.

Type: Lesson Plan

Students will use reading strategies to help them understand how the DNA replication process works.

Type: Lesson Plan

Students will examine Gregor Mendel's laws of genetics in this lesson. Students will first explore the range of variation in human physical traits and discuss where this variation comes from. They will be then paired into groups and given the role of genetic counselors that are trying to predict the traits of offspring using traits of their parents. A toss of a coin will represent alleles for various characteristics. Students will combine dominant and recessive traits to determine the phenotype and genotype of their genetic babies. Their predicted baby will be displayed for peers to view. As an extension to this activity, the students can learn that through gene technology, parents may soon have more choices available to them: hair color, physical size, intelligence. Students canl research and evaluate how can science answer new and ethical questions.

Type: Lesson Plan

Students will read "Your Genes, Your Choices." They will explore the impact of Biotechnology and create a brochure that represents what they have learned. By the end of the lesson, students will have a better understanding of DNA, GMOs, and Biotechnology.

"A Taste of DNA" is an activity-based lesson intended to be used as a reinforcement of the concepts associated with the structure of DNA and building DNA. It covers information pertaining to base pairing, DNA shape and structure, cellular organelles, and the function of DNA. In this lesson students will have the opportunity to move around the classroom, build a long strand across the science floor, and create their own strand with the knowledge they've gained.

In this lesson, students explore morphology (body shape) of fish and how they can indicate the fish"s lifestyle.

In this lesson students will investigate pedigrees and culminate in an activity where students create their own or imaginary pedigree.

Type: Lesson Plan

This is a lesson on genes, alleles and chromosomes. This lesson will teach dominant and recessive genes.

Beginning genetics lesson for 7th grade students.

Type: Lesson Plan

Through this lesson, students will use pedigree analysis in the context of mitochondrial DNA inheritance to determine how they would identify a missing person.

Type: Lesson Plan

Students will discover how DNA will "code" for traits by performing a lab activity where segments of paper DNA (genes) are picked at random, a list of traits is made, and a dog is drawn featuring its genetic traits.

Type: Lesson Plan

Students randomly select jelly beans (or other candy) that represent genes for several human traits such as tongue-rolling ability and eye color. Then, working in pairs (preferably of mixed gender), students randomly choose new pairs of jelly beans from those corresponding to their own genotypes. The new pairs are placed on toothpicks to represent the chromosomes of the couple's offspring. Finally, students compare genotypes and phenotypes of parents and offspring for all the "couples" in the class. In particular, they look to see if there are cases where parents and offspring share the exact same genotype and/or phenotype, and consider how the results would differ if they repeated the simulation using more than four traits.

Type: Lesson Plan

Students will use toothpicks (representing chromosomes) with dots on them (representing genes) to understand how traits are passed from parents to offspring. They will understand the relationship between genes, chromosomes, and traits.

Type: Lesson Plan

Explore heredity--how genetic information in DNA is passed from parents to offspring. In this interactive tutorial, you'll see how inherited genetic information impacts traits in offspring.

As a class, students work through an example showing how DNA provides the "recipe" for making our body proteins. They see how the pattern of nucleotide bases (adenine, thymine, guanine, cytosine) forms the double helix ladder shape of DNA, and serves as the code for the steps required to make genes. They also learn some ways that engineers and scientists are applying their understanding of DNA in our world.

This informational text resource is intended to support reading in the content area. Scientists used ancient bones to compare Neandertal DNA to that of modern humans from around the globe. The results are surprising: many of us are closer to Neandertals than previously thought. Once considered very unlikely, scientists now believe that humans and Neandertals may have interbred.

This article reveals how scientists have found a way to make a synthetic chromosome and insert it into yeast cells. Scientists discovered that this chromosome can alter or create new traits in an organism. This research could lead to creating an entirely synthetic genome, which scientists expect to accomplish in the next few years.

Studying dog DNA may have many applications including helping scientists to have a better understanding of canine origins and how dogs became domesticated. Understanding and locating certain genes has many breeding applications. Studying and understanding dog diseases may be able to further the study of human diseases.

This resource comes from the Cold Springs Harbor Laboratory: DNA from the Beginning online module series. There are 41 modules located on this site all focused on DNA and organized by individual concepts. The science behind each concept is explained in each module by: animations, an image gallery, video interviews, problems, biographies, and additional links. This is the 2nd module in the series, and it is focused on how genes come in pairs.

This website allows students and/or teachers to refresh their memory on terms such as DNA, traits, heredity, and genetics.

In this video module, students learn how scientists use genetic information from dogs to find out which gene (out of all 20,000 dog genes) is associated with any specific trait or disease of interest. This method involves comparing hundreds of dogs with the trait to hundreds of dogs not displaying the trait, and examining which position on the dog DNA is correlated with the trait (i.e. has one DNA sequence in dogs with the trait but another DNA sequence in dogs not displaying the trait). Students will also learn something about the history of dog breeds and how this history helps us find genes. The methods shown are the same as those used in studies looking for genes in people for diseases like cancer, diabetes, and heart disease. This lesson will take one full class period. In preparation for the lesson, it may be helpful for students to have some basic understanding of what DNA is and that differences in DNA between people can cause genetic disorders. However, these topics are reviewed briefly in the lesson. All necessary handouts and worksheets are downloadable in Word and PDF formats, and students need only paper and pen/pencil to complete the lesson. Other than a few group discussion questions, there are four main in-class activities in this lesson. First, students match 4 dog breeds to 4 breed behaviors. Second, students make a dog breed by choosing founders from 28 dogs. Third, students complete a chart showing 3 DNA positions in 8 dogs to demonstrate understanding of what it means for a site on the DNA to be correlated with a specific trait. Fourth, students use real DNA data from a specific scientific study to find the gene that is altered in boxer dogs displaying the trait of white coat color.
