Science Education Partnership Award: Development and Genetics
This unit introduces students to fundamental concepts of how their brain grows. Lessons cover concepts at a wide range of perspectives: from systems (shape and size changes) to cells (cell division and migration) to molecules (genes and proteins). The earliest stages of brain maturation are covered from how brain cells grow their axons and dendrites, and establish interconnections, to the action of chromosomes and genes, including the genetic instructions (i.e., DNA-RNA-protein) that are the "recipe for life" Because of the human genome project, genetics and molecular biology are increasingly present in today's media. As part of progressive science education, children need to become aware of the contributions of genes and healthy environments to typical maturation of brain and behavior, as well as to better recognize atypical conditions that may occur in the world around them. Portions of this unit were pilot-tested in 3rd and 6th grade classrooms last year. Further implementation in all grades is planned this year.
| Title of Lesson |
Brief Description |
| Brain Development and Cell Movement |
Students explore size and shape changes in major brain parts, cell division and migration in early stages of brain development with interactive models. |
| How the Brain Develops Its Connections |
Students learn how brain cells grow dendrites and axons and how they form connections with other brain cells. |
| Why We Are the Way We Are |
Students are introduced to genetics by learning about traits, chromosomes, and genes with constructing models. |
| Recipe for Life |
Students learn how the genetic code is copied and translated into proteins for healthy cells by "cracking" the "secret" codes. |
