This slit is the glottis, and it is the opening to the lungs. (You may need to use your probe to get it to open up). Just behind the tongue, and before you reach the esophagus is a slit like opening. To what structure does the Eustachian tube attach? _Ĥ. They are used to equalize pressure in the inner ear while the frog is swimming. Close to the angles of the jaw are two openings, one on each side. Use a probe to poke into the esophagus.ģ. In the center of the mouth, toward the back is a single round opening, the esophagus. Draw a sketch of the tongue, paying attention to its shape.Ģ. Does it attach to the front or the back of the mouth? _ (You may remove the tongue). Cut deeply so that the frog's mouth opens wide enough to view the structures inside.ġ.
Pry the frog's mouth open and use scissors to cut the angles of the frog's jaws open. Measure the diameter (distance across the circle) of the tympanic membrane. The tympanic membrane is used for hearing. Just behind the eyes on the frog's head is a circular structure called the tympanic membrane. What color is the nictitating membrane? _ What color is the eyeball? _Ħ.
Use tweezers to carefully remove the nictitating membrane. Locate the frog's eyes, the nictitating membrane is a clear membrane that attached to the bottom of the eye. Compare the length of your frog to other frogsĥ. Use a ruler to measure your from the tip of the head to the end of the frog's backbone. How many toes are present? _Are the toes webbed? _Ĥ. How many toes are present on each foot? _ Are they webbed? _ģ. Dorsal side color _ Ventral side color _Ģ. Observe the dorsal and ventral sides of the frog. Science teachers, school administrators, educators, and the scientific community are faced with ethical controversies over animal dissection in classrooms.\( \newcommand\)ġ. Simulation has been proposed as a way of dealing with this issue. One intriguing previous finding was that use of an interactive videodisc dissection facilitated performance on a subsequent actual dissection. This study examined the prior use of simulation of frog dissection in improving students' actual dissection performance and learning of frog anatomy and morphology. There were three experimental conditions: simulation before dissection (SBD) dissection before simulation (DBS) or dissection-only (DO). Results of the study indicated that students receiving SBD performed significantly better than students receiving DBS or DO on both actual dissection and knowledge of the anatomy and morphology. Students' attitudes toward the use of animals for dissection did not change significantly from pretest to posttest and did not interact with treatment. The genders did not differ in achievement, but males were more favorable towards dissection and computers than were females. The Journal of Science Education and Technology is an international and interdisciplinary forum for both invited and contributed peer reviewed articles that advance science education at all levels. Remember to record your observations and answers on this sheet. The journal publishes a broad range of papers covering theory and practice in order to facilitate future efforts of individuals and groups involved in the field. Also, you will be removing organs from the frog and placing them on a dissection sheet to be. Topics fall under the categories of disciplinary (e.g., biology, chemistry, physics, mathematics, computer science, and engineering), technological (e.g., computer, video, audio, and print), or organizational (e.g., legislation, administration, implementation, and teacher enhancement). In addition to works in the fields mentioned above and case studies of exemplary implementations, the journal publishes reviews of books, videotapes, software and relevant products to help reach our common goal: excellence in science education.Slide Topic: Frog Dissection Digestive Urogenital Frog Dissection Frog Dissection Worksheet Frog Dissection Lab Frog Dissection External Anatomy Worksheet Answers Recognizing technology's growing role in both the understanding and development of science and in the delivery of information, the journal includes technology as a component of science education.
