Lumbriculus: Contraction Rate of the Dorsal Blood Vessel
Carolina LabSheets™ Overview In this introductory physiology lab, students determine the contraction rate of the dorsal blood vessel of the blackworm Lumbriculus. Students then design and conduct an experiment to determine the effect of temperature change or chemical exposure on the contraction rate. Student Lab Sheet Needed Materials* Lumbriculus culture (141720 for 30 students) dropping […]
Investigating Hatching of Brine Shrimp Eggs
Carolina LabSheets™ Overview In this lab students study the hatching of brine shrimp eggs and design an experiment to see what factors influence hatching. Brine shrimp, genus Artemia, are found in saline lakes on all continents except Antarctica. They tolerate a wide range of salt concentrations. Brine shrimp produce two different types of eggs. In […]
Introduction to Protists: Amoeba
Carolina LabSheets™ Overview In this lab, students will observe Amoeba proteus as an example of an animal-like protist. Traditionally, amoebas were classified under Domain Eukarya, Kingdom Protista, and Phylum Amoebozoa. However, it is widely recognized that Protista is not a natural grouping. Amoebozoa are more closely related to fungi and animals than they are to […]
