Testing for Segregation of Alleles
Carolina LabSheets™ Overview In this lab, students test corn pollen for evidence of the segregation of alleles. The gene locus is waxy endosperm on chromosome 9. Students should be familiar with the iodine test for starch before performing this lab. Download Student Lab Sheet Needed Materials Starchy: Waxy Pollen (177010) for up to 25 students […]
Using Planarian Reproduction as a Path to Hands-On Inquiry Learning
Planarians are fascinating animals best known for their ability to regenerate from even very small pieces of their bodies. A common classroom lab involves cutting planarians into an anterior and a posterior half and watching them regenerate. What some people don’t realize is that splitting in half—voluntarily!—is also a planarian reproductive strategy. Devising experiments to […]
Introductory Genetics with Drosophila
Carolina LabSheets™ Overview Drosophila is one of the most popular model organisms for the study of genetics. This LabSheet can be used with a variety of our Drosophila cultures and sets in studies of monohybrid, dihybrid, and sex-linked crosses. The following crosses are especially recommended for introductory genetics activities although many others can be done. See our complete […]

Introduction to Prokaryotes: Archaea
Carolina LabSheets™ Overview In this lab, students are introduced to Halobacterium, a representative of the Archaea, one of the three domains of life (along with Bacteria and Eukarya). Halobacterium is an extremophile, requiring a hypersaline environment for its growth. At the saline levels found in the human body, Halobacterium will lyse. This makes it one of the safest microbes for […]
Introduction to Planaria
Carolina LabSheets™ Overview In this lab, students examine the anatomy and behavior of the planarian, a simple animal with bilateral symmetry. The activity does not cover regeneration.For that, see our 132900 Carolina BioKits®: Planaria Regeneration or our Carolina™ Protozoa and Invertebrates Manual. Download Student Lab Sheet Download Planarian Anatomy Sheet Needed Materials Planaria (132950 or similar culture) for […]
