Earth and Space Sciences in All Science Courses
Earth and space science concepts can be incorporated into biology, chemistry, and physics. What are Earth and space sciences? Earth and space sciences, an interdisciplinary course of study, applies the principles of physics, chemistry, and biology to explain observed interactions among Earth’s four primary systems–the biosphere, lithosphere, hydrosphere, and atmosphere–while recognizing Earth’s place in space […]
Dissection Options for Remote or Socially Distanced Labs
These dissection activities engage students whether they’re learning in the classroom or remotely. With the increasing popularity of distance learning, as well as the continued threat of COVID-19, many teachers are looking for dissection options that will work well for remote or socially distanced labs. At Carolina, we offer several options that allow your students […]
Teach Life Cycles with the Tobacco Hornworm
Bring in something new and different–something that may be the highlight of your semester. In the spring, many teachers and students look forward to studying life cycles because the accompanying hands-on activity is a highlight of the semester. This unit generally involves classroom observation of the metamorphosis of butterfly larvae or tadpoles. This is an […]
The Genome Age: Detecting Transgenes in Genetically Modified Food
Capitalize on students’ interest in forensic science as they use polymerase chain reaction to detect foreign genes in important food plants. Molecular genetic techniques have been used to add transgenes into the genomes of a number of important food plants, and these foreign genes can be readily detected using polymerase chain reaction (PCR). The experiment […]

Mole Day Celebration Happy Mole Day. It’s party time! Break out the . . . the . . . the what? How do you celebrate the value of the Avogadro constant and why would you want to anyway? Keep reading and we’ll give you all kinds of ways to commemorate the big day. As for […]
Investigating Enzyme Reaction Rates Using Toothpickase
A dry lab activity Objectives At the end of this activity, students should be able to demonstrate their understanding of the vocabulary describing an enzyme reaction, including the following terms: enzyme, quaternary structure, active site, substrate, products, V-max, substrate concentration, competitive inhibitors, and enzyme concentration. Background The vocabulary needed to describe an enzyme reaction can […]
12 Safe Practices for the Microbiology Laboratory
These best practices will help you safely contain microorganisms in your lab. Treat all microorganisms as potential pathogens. While the majority of microorganisms are not pathogenic to humans and have never been shown to cause illness, under unusual circumstances a few microorganisms that are not normally pathogenic can act as pathogens. Treat all microorganisms–especially unknown cultures–as […]
Derivation of the Kinematics Equation
High school physics courses usually begin with a study of classical mechanics. Early in the course students are introduced to the equations of motion, the kinematics equations. Kinematics Kinematics is the study of the motion of objects without concern for the forces causing the motion. These familiar equations allow students to analyze and predict the […]

Fox Domestication and Poison Resistance in Rodents
Examples to Use When Teaching About Selection and Evolution: Fox Domestication and Poison Resistance in Rodents Evolution and the role that natural selection plays in evolution can be difficult to teach. Evolution occurs over many generations and generally over long periods of time, increasing the abstraction of the concept for many students. Using concrete examples […]
