Zebrafish Development (Phenomenon) - 0 views

Lottie Peppers on 30 May 21This two-minute video provides brief background on the use of zebrafish as a model in studying animal development, before showing a time-lapse sequence of a fertilized zebrafish egg developing into a larva. The video includes some annotations that help orient the viewer during the time-lapse sequence. Teachers might want to mute the narration beginning at 0:42 min to avoid giving students too much information. This phenomenon could stimulate the following driving questions: How does the zebrafish develop from one cell to the many cells that make up the larva? How do the zebrafish cells divide? How are the developing zebrafish cells similar and different from each other? If all cells in the zebrafish develop from the same original cell, then how do some cells develop differently than others? How are cell division and growth related?
