The digestive system consists of the organs of the digestive tract, or food tube, and the digestive glands. In the pharynx, there are several openings: one into the esophagus, the tube into which food is swallowed one into the glottis, through which air enters the larynx, or voice box and two into the Eustachian tubes, which connect the pharynx to the ear. Also inside the mouth behind the tongue is the pharynx, or throat. Inside the mouth are two internal nares, or openings into the nostrils two vomerine teeth in the middle of the roof of the mouth and two maxillary teeth at the sides of the mouth. The third lid, called the nictitating membrane, is transparent. On the outside of the frog’s head are two external nares, or nostrils two tympani, or eardrums and two eyes, each of which has three lids. You can try out the demo here and the App.As members of the class Amphibia, frogs may live some of their adult lives on land, but they must return to water to reproduce.

However, Froguts isn't free for homeschoolers. We've heard a number of people recommend Froguts as the most precise (at times, tedious and annoying). Students receive comprehensive explanations and analysis of the following systems:Ī very precise and realistic dissection tool?įor the kinesthetic and hands-on learners that won't appreciate the McGraw-Hill interface, there are more challenging and precise tools available. No need to worry about mistakes! Although the explanations are solid, the interactive features are definitely lacking. This process can be repeated multiple times.

There are interactive features that teach students how to make the actual incisions.

Students will see a mix of real video footage and images. I like that you can break the steps up over multiple days. This is a step-by-step narrated audio and video program. If you know, or use, another tool we missed, please comment below and we'll add it! Virtual Lab from McGraw-Hill Here is a list of some great online tools for virtual frog dissection. Some are incredibly realistic while others come with built-in quizzes. No mess, no smells, no 'gross,' frog dissection labs.Įach tool will have strengths and weaknesses. Mistakes in online labs can be 'redone.' No second guessing which organ is what. How can an online program provide a better learning environment than a hands-on lab?ĭigital images are often higher quality. There is also the question, ' Is it humane?' This question is especially pertinent now that there are comparable alternatives.Īrguably, there are online/digital programs and tools that provide an even better environment and educational experience. But there are many reasons why schools and homeschools have stopped performing the 'classic' frog dissection. Some educators might disagree with me, saying that queasiness isn't an excuse for skipping a hands-on dissection lab. And then I started exploring digital options for my youngest who has a 'sensitive stomach' when it comes to hard science. However, after my oldest completed an online conceptual physics lab, I realized that technology has far surpassed my expectations. Back in 'my day' there was no such thing as 'virtual labs,' much less 'virtual dissections.' Like it or not, grossed out or engaged, we all had to suffer through the process (and smells, ugh!).
