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 […]
MOM’s Acid-Base Chemistry
Introduction In this experiment, students react milk of magnesia with vinegar to study acid-base chemistry, chemical equilibrium, solubility, and heat of neutralization. Milk of magnesia (MOM), which still finds wide use as a laxative and antacid, is a suspension of magnesium hydroxide in water. The suspended particles of magnesium hydroxide give MOM its characteristic milky-white […]
