On Down — Down Syndrome

Scientists have known for some time that Down Syndrome, the most common chromosomal abnormality, is caused by an additional chromosome #21. However, new fetal stem cell research is demonstrating that it is not only the presence of this additional chromosome, but also what the genes are missing, that may impede the development of a Down Syndrome brain.

All 50 Secrets of the Sequence videos have an accompanying classroom-tested lesson that encourages students to further explore the video topics. Each lesson includes background information, state and national science standards, discussion questions and answers, teacher notes and an activity that will ensure a hands-on, “minds-on” experience.
