Six pages begin with a detailed introduction to meiosis and homologous chromosome pairs. Instructions guide learners through a simulation in which they draw craft sticks marked with autosomes in order to decode the genes inherited by...

In this biology activity, students identify and describe a number of easily observable genetic traits and compare the traits they have with other students. Then they identify and describe that some traits are common while others are not...

Students explain the difference between dominant and recessive genes, identify what causes differences in the traits of parents and their offspring, and explain how sex is determined. They will also improve their reading and...

In this biology worksheet, 9th graders identify which seed color is dominant in the given chart and explain why it is. Then they create a Punnett square showing the alleles of the parent plants and first generation of offspring.

Students investigate dominant and recessive traits by studying their schoolmates.  In this genetics lesson, students analyze specific traits of other children in school and create a database of information based on whom carries...

In this biology instructional activity, 9th graders create a Punnett square to show the possible offspring of a carrier female and a normal male for color blindness. Then they draw a pedigree for the family and indicate whether the...

In this biology worksheet, 9th graders describe how two alleles can produce three phenotypes. Then they create a Punnett square showing the possible offspring of red and white cattle. Students also determine the genotypes and phenotype...

Young scholars, in groups, research, analyze and synthesize information on genetic diseases. After watching a video on genetics, groups perform research on a variety of genetic diseases and present their findings to the class.

Students explore the concept of extinction by studying dinosaurs. In this dinosaur lesson, students distinguish between extinct creatures and those that still exist.

Students explore human behavior by participating in a class science game. In this human characteristics lesson, students identify different human traits that are passed down by each generation and the purpose each of them have. Students...

In this literacy learning exercise, middle schoolers find the words that are related to the concept that is the theme of the word search puzzle.
