DISSECTING FROGS!

A WebQuest for Grade 8 Biology

DISSECTING FROGS!

Introduction

You have just been hired as a physiology scientist in Dr. Frogger’s laboratory. Your goal is to investigate the internal anatomy of a frog. Unlike the boys in Aesop’s fable below, you are sensitive to the frogs’ feelings. Therefore, you will be conducting your investigations virtually. What organs are present? Where are they located? What are their functions? Put on your lab aprons and goggles and venture on to your tasks.

The Boys an the Frog

An Aesop’s Fable

Some boys, playing near a pond, saw a number of Frogs in the water and began to pelt them with stones. They killed several of them, when one of the Frogs, lifting his head out of the water, cried out: “Pray stop, my boys: what is sport to you, is death to us.”

Task

Task 1: Complete a virtual dissection of a frog.

Task 2: Research the functions of key organs identified in the virtual dissection.

Task 3: Complete a worksheet as a demonstration of what you have learned.

As a Scientist in Dr. Frogger’s Laboratory, What are you expected to accomplish?

Task 2:

Review the structures and functions of a frog’s organs. Pay attention particularly to the heart, liver, lungs, stomach, intestine, kidneys, bladder, brain, skeleton, and skin.

Task 3:

Complete the worksheet, identifying the location and function of the frog’s organs listed.
