Activity: Gizmo - Embryo Development

Objective

Overview

Materials

● I can analyze displays of pictorial data to compare

● Explore how a fertilized cell develops into an embryo, a fetus, and eventually an adult organism. Compare embryo development in different vertebrate species and try to guess which embryo belongs to each species. Use dyes to trace the differentiation of cells during early embryo development, from the zygote to the neurula.
