Featuring Carolina's Perfect Solution® specimens. For a class of 30. Introduces students to basic vertebrate anatomy through dissection of the bullfrog, a typical vertebrate. Bullfrogs are larger than grass frogs, and offer easier organ identification. Updated to support NGSS and 3-dimensional instruction!

Product Details
Students are introduced to basic vertebrate anatomy through the dissection of a bullfrog. As a pre-lab, students watch a phenomenon video and answer related questions to activate their prior knowledge. Students then explore the bullfrog’s external and internal anatomy by body system as they progress through the lab dissection. During the activity, they locate key structures, relate structure to function, and note adaptations. The comprehensive student guide provides a glossary and postlab assessment questions to help reinforce and assess understanding.

This classroom kit is designed for a class of 30. It includes 15 Carolina's Perfect Solution® plain bullfrogs (no injection), 15 disposable dissecting trays, 15 self-locking storage bags, and a comprehensive teacher’s manual with reproducible student guide. The teacher's manual contains procedural and preparation instructions, safety information, and more. The student guide provides step-by-step dissection instructions, labeled color photographs and illustrations, a prelab, assessment questions, and a glossary.

Time Requirement
Teacher prep, 10 minutes. Prelab, 30 minutes. Dissection, 60–90 minutes (or can be divided into multiple class periods). Assessment, 45–60 minutes. Prelab and Assessment can be completed as homework. Note: Carolina’s Wetting Solution (items #220120A and #220121A) is recommended if completing dissection over multiple days.

Digital Resources
Includes 1-year access to digital resources that support 3-dimensional instruction for NGSS. Digital resources may include a teacher’s manual and student guide, prelab activities and setup videos, phenomenon videos, simulations, and post-lab analysis and assessments.
