Be aware that this is an incremental lab. Students must complete each part before receiving the packet for the next part. I will know they have completed each part because there are questions the student must respond to in the classroom. Being this is a five-week course, note that if you want your child to dissect along with the instructor, it will take time for your specimen to arrive. So it is imperative that the student begin immediately. There are many activities he or she can begin working on.
This course is designed for a student to learn about amphibians; specifically the leopard frog. Also to watch or follow the instructor on how to prepare to dissect a frog.
In this lesson, the student will be introduced to the different kinds of equipment needed to perform a dissection in the first video. They will learn how they can make their own kit from items around their home.
Students are provided diagrams and instructions to label the frog as they dissect. They can watch the instructor do a step-by-step dissection of a leopard frog’s external anatomy in the second video. Students will have handouts to refer to and learn the tips to easily access the mouth of a frog in the third video.
***Please note that the videos are set to private on Youtube because these are classes people pay a fee for; they are not free to the public. Let me know your email to directly send the links to you a day or two prior to your dissections so there is no delay.
Through an asynchronous format, students can discuss what they found unusual or interesting in the anatomy of the frog. Questions are prompted in the Google doc layout of the course, which makes the student accountable to the instructor.
Students can interact with each other through an I spy game via the classroom. An example would be:
I spy something triangular inside the mouth of the frog. Their peers can try to guess what it is via the videos or the dissection itself. The answer to the prompt would be. I spy a tongue! Then, once a peer responds, that student can return with I spy a ________; to keep the game going.
Students may take the online quiz to review the material learned in this lesson.
Lesson 3 Frog Dissection P2 Eye, Brain, Skin, and Muscles
This asynchronous course is for a student to watch or follow the instructor. The demo video consists of discussion questions for students to submit to the instructor or with their peers. An online quiz evaluates the student’s understanding.
Prior to the dissection, students will become familiar with amphibian characteristics through a video.
Then, I will dissect a leopard frog for the student using a step by step process through a Google Doc and video. We will begin by removing the lens from the eyes, exposing the brain, skinning, and identify major muscles. In each step of the way, the student will hear a school bell ring. They are to pause and take a break.
Throughout the video, there are observational discussion questions for students to submit to the instructor or share with their peers.
Some of the discussion questions are as follows:
Why do frogs have three eyelids?
How are the eyes similar and different from human eyes?
When exposing the brain what did you notice about the frog’s cranium?
How is the frog’s brain similar or different from the human brain?
(These are just a few of the questions students will discuss in this dissection course.)
This is a lengthy dissection and preparing for labeling the muscles is a meticulous process since labels must be cut out and attached to each pin. Printable labels will be provided for each step. Upon completion, there is a Google Form multiple-choice online quiz to evaluate the student’s understanding of how to dissect these parts of the Frog. They are to take the quiz as many times as they like until they make all the possible points. This is part of the learning experience.
In this lesson, the student will learn the internal anatomy of the frog through diagrams and videos. They will watch the instructor do a step-by-step dissection of a leopard frog’s internal anatomy video after they have completed their coloring page and studied the diagrams. In conclusion, students are to write an observational paragraph using various questions that the instructor has touched upon. They are to take the online quiz to review the material learned in this class. This quiz can be taken multiple times. This is part of the learning experience.
***Students may share their experiences with each other through the classroom platform. Students do need to respond to questions from Part 1 and 2 prior to doing P3 of the frog dissection. They will also engage in the “High Five Question” game to interact with their peers.
