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...

Students plant seeds in order to investigate and explore the questions: "How do seed companies develop varieties of plants?" and "What is the ideal plant?" Students will study related vocabulary and sketch seeds as they emerge. Students...

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...

Students examine the molecular studies of organisms that have led to a new era in their understanding of speciation and evolutionary relationships. Students study the allelic frequency of genes controlling specific molecules and assess...

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...
