Two-Point Linkage with Drosophila
Carolina LabSheets™ Overview In this lab students explore the genetic consequences of gene linkage using an F1 cross of Drosophila. 172050 Two-Point Linkage:The vial of F1 flies is from a cross between females having yellow bodies and white eyes (172290 yellow white) and wild-type males having gray bodies and red eyes (172100 wild type). Yellow […]
Vinegar Eels
Carolina LabSheets™ Overview In this lab, students observe vinegar eels. These small animals, barely visible without magnification, are found in unpasteurized cider vinegar, where they feed on the bacteria responsible for the conversion of apples to vinegar. Vinegar eels, Turbatrix aceti or Anguillula aceti (Muller, 1783), are examples of roundworms, or nematodes.. Download Student Lab […]
Investigating a Phenotype
Carolina LabSheets™ Overview A phenotype is an expressed trait. Most phenotypes studied in introductory genetics classes are visually conspicuous traits such as wing shape or eye color. In this activity, students investigate a phenotype that is not so conspicuous, and they perform a simple chemical test to reveal the underlying basis of the phenotype. Corn […]
Seed Germination
Carolina LabSheets™ Overview The story of how a seed becomes a plant is fascinating to young students. These activities will help them explore the process of germination. Students will observe the internal structure of a seed, seed germination, and early seedling growth. The activities are recommended for grades K–4 and can be done as part […]
Pill Bug Behavior
Carolina LabSheets™ Overview This activity is an introduction to animal behavior. Students conduct an experiment to test the response of pill bugs (Armadillidium vulgare) to conditions of low and high humidity. Pill bugs are crustaceans. Most crustaceans are aquatic, but pill bugs are terrestrial. Even so, they retain gills as respiratory organs, which restricts them […]
Introduction to Protists: Euglena
Carolina LabSheets™ Overview In this lab, students observe Euglena, a protist that combines some characteristics of animals with the plant-like ability to photosynthesize. Traditionally, Euglenas were classified under Domain Eukarya, Kingdom Protista, and Phylum Euglenozoa (sometimes Euglenophyta). However, it is widely recognized that Protista is not a natural grouping. Currently, Euglena is classified in the […]

Introduction to Prokaryotes: Bacteria
Carolina LabSheets™ Overview In this lab students are introduced to the Domain Bacteria (Eubacteria). They will make smears of bacteria on microscope slides from pure cultures, perform a simple stain, and observe their stained slides under a microscope. The stained slides are best observed at 700–1000× with oil immersion; however, they can be viewed under […]
