, Name Nico Vigneri Date: 2/2/2022
:
Student Exploration: Frog Dissection
Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts
in the orange boxes.
Vocabulary: anatomy, appendix, diaphragm, dissect, fertilize, heart, large intestines, lungs,
lymph vessels, ovary, oviduct, ovisac, rectum, sternum, testis, vasa efferentia, vertebrae
Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
1. Name some of the organs humans use to digest food.
The mouth, esophagus, stomach, pancreas, liver, gallbladder, small intestine, and large
intestine.
2. Do you think frogs have the same or different organs? Explain.
I think that frogs will have mostly similar organs that are slightly different from ours but
fulfill the same basic purposes.
Gizmo Warm-up
Scientists dissect (cut up) other organisms to learn more
about their anatomy, or body structure. In doing so, scientists
can also learn more about human anatomy. In the Frog
Dissection Gizmo, you will complete a virtual dissection of a
female and male frog.
First, select the Female frog. Then click on the rotate button ( ).
With the rotate button selected, click and drag on the frog to
rotate it.
Observe what the female frog looks like.
Now select Show male at the bottom left to switch to the male
frog. Rotate around the male frog to observe what it looks like.
Click Show male and Show female to toggle back and forth
between the two frogs.
1. Do you notice any differences between male and female frogs?
Yes
2. Describe any differences you see.
The female frog is larger and does not have the rough patches on its hands like the male
frog does.
