This week the Spotlight shines on Mr. Scott Uhlhorn’s and Mr. Duane Potts’ seventh grade science classes. Each spring, the science department sharpens up the scalpels, passes out the rubber gloves, and guides their classes through the inner workings of some would-be Kermit’s.
“Frog dissection is a great science activity,” reports Mr. Uhlhorn. “Dissection is an important tool when studying anatomy and comparative anatomy. It is also a good lesson in teamwork and cooperation (kids work with a partner).”
Each team is assigned a frog (which they name) and begin a series of six step-by-step dissections over the course of a week. The students are also responsible for a series of detailed drawings.
Mr. Potts reports, “Dissection is hands-on learning at its best. The kids are engaged from the moment they are given their frog to the final cut of the brain dissection.”
The unit is evaluated by a lab test where students rotate between stations and must be able to identify various anatomical features of the frogs. A lesson on frog metamorphosis is also presented. The graphic nature of this project caused some of the students to be as ‘green’ as their frogs at times but overall everyone survived and learned from it. Way to go, Mr. Uhlhorn and Mr. Potts!
