primitive streak, trilaminar disk, zygote
Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
1. The images below show embryos of different species at different stages of development.
Label the images below with 1-4 from least developed to most developed.
A 4 B 1 C 3 D 2
2. Which image above do you think is a human? Explain. Example B is human
because its smaller
Gizmo Warm-up
Embryology is the study of the development of embryos from a
single cell to a multicellular fetus. In the Embryo Development
Gizmo, you will compare the development of different animals
and learn the details of mammalian development. To begin, be
sure the COMPARE tab is selected.
1. What do the images have in common? They have a similar shape
Click on the check box to turn on Scale bars and labels. You are observing the zygotes, or
fertilized single cells, of five animals.

, 2. At this point, are you able to tell which animal is which? no Explain? Its to small to tell
