Survey of Protista
Carolina LabSheets™ Overview In this lab, students observe a variety of protists and record basic observations of them. Traditionally, protists were classified under Domain Eukarya, Kingdom Protista, and were divided into phyla mainly on the basis of their mode of locomotion. However, it has long been recognized that Protista is not a natural grouping, and that mode […]
Meiosis and Genetics
Carolina LabSheets™ Overview In this lab, students investigate how the events of meiosis relate to Mendelian genetics. The lab is designed to supplement the Meiosis Activity of our Carolina BioKits ® : Chromosome Simulation. Download Student Lab Sheet Needed Materials Carolina BioKits ® : Chromosome Simulation (#171100) Optional Materials Small, colored adhesive dots can be used […]
Modeling Mitosis and Meiosis
Introduction Have student groups use sock “chromosomes” and string to model mitosis and meiosis. These 2 simple activities take approximately 30 min to complete. Discussion questions and answers are provided so that you can assess student understanding of each type of cell division. Next Generation Science Standards Life Science The Cell The Molecular Basis of […]

The activity can be used as a unit introduction for human senses or as a stand-alone olfactory sensation […]
Carbon Snake
A Carolina EssentialsTM Demonstration Total Time: 15 mins Prep: 15 mins | Activity: 10-15 mins Life Science 8-12 Middle/High School Overview During this teacher-directed demonstration of an exothermic reaction, students observe the dehydration of a carbohydrate using concentrated sulfuric acid. Use the demonstration to illustrate topics such as reaction kinetics, organic reaction types, and energy […]
Calorimetry: Measuring the Energy in Foods
A Carolina EssentialsTM Activity Total Time: 65-90 mins Prep: 20-30 mins | Activity: 45-60 mins Life Science 9-12 High School Overview During this investigation, students will determine the calories—or heat content—of 3 different foods. From the experiment setup and data collected, students will have the evidence necessary to construct a model of heat transferred through […]
Constructing and Testing a Dichotomous Key Model for Fruit

Observing Plant Cells
CAROLINA LABSHEETS Quick Links Close Quick Links Open Quick Links Overview Materials Procedures & Prep Kit Overview Materials Procedures & Prep Kit Overview In this lab students observe Elodea leaves under magnification. They will see cell walls and chloroplasts. From the movement of chloroplasts they will infer that cyclosis, or protoplasmic streaming, is occurring. They also will […]
Introduction to Photosynthesis Using Coleus Plants
Carolina LabSheets™ Overview The simple exercises that students perform in this lab demonstrate that plants produce glucose through photosynthesis, that plants convert at least some of the glucose to starch, and that sunlight is a critical factor in photosynthesis. Students expose Coleus leaves to varying amounts of light. These sample leaves are then subjected to an iodine […]
Ocular Dominance
A Carolina EssentialsTM Activity Total Time: 15-30 mins Prep: 15 mins | Activity: 15-30 mins Life Science 8-12 Middle/High School Overview This short, individual engagement activity introduces the senses, sensation and perception, and evolutionary differences in predator-prey relationships. Students differentiate binocular vison and panoramic vision, determine their own ocular dominance, calculate class data percentages, and […]
