Download a photograph of a frog or cut one out of a magazine, if you're not on a computer. You can also use a frog design or draw one yourself.
Draw straight lines, beginning from certain parts or organs of the frog and reaching the surrounding empty space.
Write the name of each part on the end of its corresponding straight line. Consult the "Frog Dissection" article on the website Biology Junction (see Resources) for the right name of each part. For example, a frog does not have a "nose" but "nostrils," while its "ears" are called "tympani" (singular: tympanum).
Draw a rectangle around the word describing each part. This can make it easier for the viewer to distinguish which word corresponds to which part, especially if many words are crammed together.
Repeat the process using designs of the frog's anatomy to label the internal organs, such as the heart, the liver and the intestines. "Frog Dissection" has detailed pictures and analyses on the frog's internal anatomy to help you label the parts. Use separate images for the male and female frog's reproductive system.
