#Frog dissection lab game series#
A well-designed site that allows students to watch a series of videos, learn how eyes function and download step-by-step. Shockwave animations illustrate each part and its function. Uses close-up photos of a fetal pig dissection. While dissection remains a controversial practice to some, Glotfelty says Taylor's turnaround exemplifies its power: that a kid who normally doesn't even like science can get downright excited about frog guts. An online program complete with study guides to demonstrate each system and quizzes with immediate feedback. One by one, Taylor and her team lay the organs on a laminated sheet of paper. "You might hear some popping and some crackling."

A lite game which shows you how to dissect a frog and identify the organs Use your mouse and follow the instructions. This is the thing they want to do," Gotfelty says.Īnd, indeed, even the faint of heart now seem eager to get started, bouncing around their dissection trays.Īs for Taylor Smith, who says she doesn't like science - she's about to use tiny scissors to cut through the frog's collarbone. If you take some more biology education in University you will remember clearly how is done frog surgery operation. "They've been looking forward to this all year. The computer model helps kids understand anatomical theory, he says, but actual dissection engages them in a rare way. The National Science Teachers Association now asks educators to give students a choice, though it also insists on the fundamental importance of dissection as a teaching tool. The Froguts online subscription service includes frog, squid, sea star, cow eye, owl pellet, fetal pig, and Mendelian genetics labs.

Melissa Torres-Gutierrez, a student in Rob Glotfelty's life sciences lab, documents dissecting a frog. as substitutes for the conventional human gross anatomy laboratory. At least nine other states have done the same. This study examined the prior use of simulation of frog dissection in improving. She took her case to court, which ultimately led to a state law that requires students be given an alternative to real animals. But that changed in 1987, when 15-year-old Jenifer Graham of Victorville, Calif., refused to dissect a frog in her biology class. Using dead animals to make these connections used to be the only option for students, whether they liked it or not. "What does this particular organ feel like? How stiff is it? Is it compressible?" "There's something visceral and important about the real thing," says David Evans, executive director of the National Science Teachers Association. Rats, cats, and fetal pigs all give insight into how our own bodies work. In high school the animals get even bigger. First, the class cut open an earthworm, then a chicken wing. "But are we really interested in how frogs' bodies work?" Glotfelty asks the class. Glotfelty's goal is to get them over the squeamish hump. The smell was awful, but it was worth it. Once I opened it, this horrendous smell came out of it.
Taylor, like many of her classmates, doesn't want to touch, much less splay open this formaldehyde-laced frog and pick out its dark, stringy organs. "I don't want to cut open no live animal," says student Taylor Smith, who is thoroughly hidden beneath a black smock, plastic goggles and rubber gloves. Which is why some of the seventh-graders at Baltimore's Patterson Park Public Charter School are seriously grossed out. And, even in death, they're remarkably slimy. Once those seals are broken, these leopard frogs emit a pungent odor.
Things like the slide rule and protractor, the Presidential Fitness Test and wooden blocks.Īmong the Bunsen burners and petri dishes of Rob Glotfelty's life sciences lab sits a stack of curious packages: dead frogs, vacuum-sealed and piled five high. There is a printable worksheet available for download here so you can take the quiz with pen and paper.

This is an online quiz called virtual frog dissection.
