Carolina’s Perfect Solution® Specimen Comparison
No need to compromise What if you could provide your students with a higher quality preserved specimen and an enhanced dissection experience while at the same time improving the safety of your learning environment? Does this sound too good to be true? We have developed a preservation formula that produces superior specimens without compromising classroom […]
Using Histology Slides to Enhance Mammalian Dissection
There are 4 main types of tissue: epithelial, muscle, nervous, and connective. Each type has a particular function and can be found to some degree in most organs. In order to understand the structure and function of each type of tissue, it is important to view them microscopically. Many tissues viewed with the naked eye […]
Demonstrating Cellular Respiration and Fermentation
Cellular respiration and fermentation are 2 of the most challenging concepts for introductory biology students, who may become so consumed by memorizing steps of the Krebs cycle and glycolysis that they lose sight of the big picture. The following demonstrations place aerobic cell respiration and fermentation firmly in grasp. First, students observe respiration in germinating seeds by detecting the carbon dioxide produced. Next, they observe the carbon dioxide gas produced by yeast fermentation.
The Chemistry of Beer
Many science teachers take their love of chemistry and microbiology out of the classroom and move it to the garage for a home beer brewing adventure. Whether you enjoy brewing your own, or enjoying the fruits of others’ brewing efforts, the art of beer is in the science.
Diffusion and Osmosis
All cells are bound by some type of permeable or semipermeable membrane that governs the ions, small molecules, and large molecules that enter and leave the cell. Diffusion is the general process of movement down a gradient that results in equal concentrations of solutes on both sides of the membrane. When water is the molecule entering or leaving the cell the process is osmosis. This guide breaks down the important information students need to know, provides links to products and free digital resources, and includes suggestions for hands-on-labs that reinforce student learning.
Using Aquatic Plants to Demonstrate Photosynthesis
Introduction Egeria densa, also known as Elodea densa because of its previously incorrect classification in the Elodea genus, is the most popular aquatic plant used to teach photosynthesis in the classroom. Originally from Brazil, E. densa has spread to temperate regions on all of the continents except Antarctica. Known for its bright green color and leafy stems, E. densa is an excellent oxygenating […]
How to Make a Good Scientific Model
Are your students able to generate observations and then construct a good scientific model? After your students complete an inquiry activity, use our scientific model checklist to guide them through constructing and refining a model. Encourage students to use the checklist to ensure their model is sound. Allow lab groups to switch models and critique them. Go […]
Forensics
Forensics is the interdisciplinary application of science to investigate and analyze evidence of historical, and most often criminal, events. In the classroom, training forensic scientists requires preparing students to be able to identify, compare, and analyze a breadth of evidence types using skills across biology, chemistry, and physics.
Ecology: Ecosystem Interactions
Carolina has everything you need to teach ecology. This guide on ecosystem interactions, breaks down the important information students need to know, provides links to products and free digital resources, and includes suggestions for hands-on-labs that reinforce student learning.
Substitute Plans
It’s that time of year again when you’re asked to provide lesson plans for a substitute who may or may not have a science background. Keep your students engaged in science with activities that are safe and easy for a substitute to manage. Make it Phenomenal! Use our Phenomena Video Gallery to get students questioning […]
